Searching the web, I have found almost no evidence that perlbrew works on cygwin. The specifics of my current issue are:
With the latest install of cygwin (which includes perl 5.14.2), I'm trying to install perl-5.14.2 using the latest perlbrew, installed from the web (not CPAN). I get a hang just after ../dist/threads-shared/t/shared_attr.t...ok is printed to build.log. This is on WinXP Pro 2002 SP3. Previous tries at using perlbrew on other builds of cygwin (which include perl 5.10.1) have also failed, but in other places.
I have posted a comment on Reini Urban's blog on blogs.perl.org and an issue/bug on github for App-perlbrew, but with no responses yet.
Is there any hope that I can get perl to build on cygwin? If not, what can I do to work around it and still use perlbrew (to unify my environments so that my cygwin environment uses perlbrew, just like my linux environment does)?
perlbrew works and perl can be built on Cygwin, with the minor annoyance that some of the unit tests hang (as you have discovered). Keep one eye on the build process output and kill the tests (usually thread related) that don't do anything for a couple of minutes using ps and kill. perlbrew should (knock on wood) run make install even if a handful of tests did not pass.
I never got perlbrew run under cygwin. But as a workaround perhaps try plenv. When I last tried it, it worked out of the box under cygwin.
A 2018 update - perlbrew works fine for me on Cygwin. However, perlbrew-installed perls will not have the patches that a system Perl has. I have a sample repo at https://github.com/cxw42/perlbrew-on-cygwin showing how I built the latest Cygwin system perl and installed it as a perlbrew perl.
In short, building Perl with prefix, site prefix, and vendor prefix set to ~/perl5/perlbrew/perls/perl-<version> will generate a Perl tree. You can drop that Perl tree into ~/perl5/perlbrew/perls/, and perlbrew will pick it up as an available Perl.

I’m a mere mortal using Cygwin on Win7 and wanting to develop perl scripts using SOAP::lite. Installation instructions I found at soaplite.com directed me to start with perl –MCPAN –e shell before attempting an > install SOAP::lite
The newb in me didn’t appreciate that my windows user profile has a space character in it and the CPAN set-up seemed to go all horribly wrong around the point where the script was writing make files for local::lib, MYMETA.yml and MYYMETA.json. I got “no such file or directory” messages quoting only the portion of the path that followed the space in my user profile.
$ uname -a
CYGWIN_NT-6.1 UKLHRL00020 2.0.4(0.287/5/3) 2015-06-09 12:22 x86_64 Cygwin
$ cpan --version
Loading internal null logger. Install Log::Log4perl for logging messages
/usr/bin/cpan version 1.61 calling Getopt::Std::getopts (version 1.06 [paranoid]),
running under Perl version 5.14.4.
[Now continuing due to backward compatibility and excessive paranoia.
See ``perldoc Getopt::Std'' about $Getopt::Std::STANDARD_HELP_VERSION.]
Nothing to install!
When I ran perl –MCPAN –e shell for the first time, it did report “Warning: You do not have write permission for Perl library directories.” and I elected for the default option [local::lib] for the approach to be taken.
So what can I do next?
Looking closer at the Cygwin’s setup-x86_64.exe, a search for “cpan” lists eight packages under the perl category for perl-CPAN-* and perl-Parse-CPAN*, which are all set to “Skip”. The package perl-CPANMeta: Perl distribution CPAN-Meta is version 2.150001-1 from cygwin.mirrors.pair.com. Since this is not installed yet, but the installed Perl5 has some knowledge of an old CPAN, I need to know if it is safe to install the latest and will it work with a space in my profile? Do I need to remove the old CPAN, and how?
You probably want to update to the latest version of ExtUtils::MakeMaker, recent versions contain various fixes for paths containing spaces. This should fix these issues.

Sinan Ünür is right. The error message is that you don't have nmake installed. This means you are attempting to compile code (probably C code) and there's no C compiler or Make program.
A while ago, I would tell people that ActiveState doesn't fully support cpan because it can't compile code. ActiveState uses it's own pre-compiled packages available via the Perl Package Manager (PPM) which can be used from the command line or from a GUI interface. If a package isn't available via the PPM and it requires compilation, you were just out of luck. I would usually recommend Strawberry Perl instead of ActivePerl for this very reason. Strawberry Perl comes with the complete MinGW environment needed for those compilable CPAN modules.
However, about a half a dozen years ago, ActiveState put together an installable PPM package for the MinGW environment. Once this is installed, ActivePerl can use CPAN.
So you have two solutions:
Install this PPM package as Sinan Ünür mentioned in his answer. Then, try Spreadsheet::ParseExcel again.
Install Strawberry Perl instead of ActiveState's Perl. Strawberry Perl seems to be more compatible with the version of Perl found on Unix/Mac/Linux systems. Then try installing the Spreadsheet::ParseExcel package.
Okay, three solutions: Install Cygwin which will give you the complete Linux Environment on your Windows machine. It can take about two hours to install, but it comes with all of the GNU utilities you've known and love, most other Unix/Linux utilities, and the BASH shell.
It's what a lot of Linux/Unix homeboys use when they get sick of that ol' C:\> prompt. Cygwin comes with the latest version of Perl and works with every single CPAN package I've tried. There are a few minor issues (Like Termcaps) where things don't quite work the way they're suppose to, but I'm generally happy with it. It even comes with X11 and allows you to run XWindow apps, and even use XWindow apps across systems -- just like a REAL operating system does!
There maybe a few instances where CPAN modules may still have issues on Windows. One has to do with archiving and unarchiving modules and the missing libz library. However, installing this MinGW package (or using Strawberry Perl or Cygwin) will solve about 95% of the cpan installation issues.
I have tried 5 times.
Computers are deterministic things. That means, unless you change the conditions under which a program runs, it will always do the same thing (except, maybe, if there is a solar flare or an EMP).
So, there is no difference between issuing the same command once versus five times. If it failed the first time, ceteris paribus, it fill fail all five times.
That said, it looks like you installed ActiveState Perl, but did not install the MinGW package which provides the gcc & dmake based build tools.
So,
C:\>ppm install MinGW
and then try to install packages.
You also have the option of building your own perl using the Community Edition of Microsoft Visual Studio 2013 tools, or any other supported compiler.
I am trying to install wxperl on strawberry. I can't install Alien::wxWidgets. I tried everything I can think of. Usually I get an error like this one:
Creating library file: ..\..\src\stc\..\..\..\lib\gcc_dll\libwxmsw28u_stc.a
compilet.exp:fake:(.edata+0x3c): undefined reference to `boot_compilet'
compilet.exp:fake:(.edata+0x40): undefined reference to `boot_compilet'
I don't know what that means. I tried with wxWidgets v 2.8.12 and 2.9.3 and various options. I started with cpanm and later evoking perl Build.PL manually with all kinds of options.
I am on Windows 7 64 bit. I tried with 5.14.2 32bit and 64bit. I am pretty sure that my path has no other perl installation than the one I currently using.
Any ideas? Thanks!
Using strawberry-perl-5.16.3.1-32bit on Windows 7.
It seems that even though the build process crashes with the error message above, Alien::wxWidgets has, in fact, been successfully made, and is ready to install.
Got the same error message building Alien::wxWidgets from SVN trunk. I ran 'build test' and the tests passed so I ran 'build install'. Wx compiled successfully, all tests passed. Padre editor compiled successfully, all tests passed, and it works well.
It is also possible to install via PPM in Strawberry perl:
ppm set repository wxPerl http://www.wxperl.co.uk/repo29 (for WxWidgets-2.9.4)
ppm install Alien::wxWidgets (version 0.61)
Unfortunately, the latest version of Padre editor requires Alien::wxWidgets 0.62, so building Alien::wxWidgets from source is necessary to make Padre from CPAN.
Alternately, you can use the Citrus Perl distribution created by Mark Dootson. One caveat, the version of Perl, 5.16.1, is not the latest, but it is more recent than DWIM Perl build of Strawberry Perl 5.14.2.1 RC.
I would recommend using the latest Strawberry Perl 5.16.3, or 5.14.4.1 for security reasons because it has a a fix for the rehashing flaw which could be used for denial of service attacks. Described here:
http://www.vuxml.org/freebsd/CVE-2013-1667.html
One idea is to install DWIM Perl, which is a Perl distribution which contains Strawberry preloaded with a whole lot of commonly used CPAN modules, and includes Alien::wxWidgets.
I'm a C/C++/Java/Unix geek by trade, but now I have to write a Perl program in Windows. So I've got Cygwin, Eclipse with EPIC installed, and simple test programs run. I do not have a Unix machine available to me that I can run Eclipse on.
But I need to use Net::TCP::Server and I can't figure out how to install it. It doesn't appear to be part of the Cygwin Perl install, and I don't want to spend 5 days learning the world of Perl and CPAN and Perl configuration. I just want to write my program.
Any simple ways of installing a Perl module in Cygwin? I'm thinking something like apt-get install would be nice, but I expect that's too much to hope for.
Thanks
$ perl -MCPAN -e shell
cpan shell -- CPAN exploration and modules installation (v1.9402)
Enter 'h' for help.
cpan[1]> install Net::TCP::Server
And it's instructive to list the configuration with the o conf command.
Seeing that some of the info here is a bit outdated and too complicated, I'd rather suggest the following. There are a few different Perl package managers in use. They are all installed with cpan (which is already part of the Cygwin Perl installation), like this:
# Install ppm (outdated)
cpan PPM
# Install cpanp (still used)
cpan CPANPLUS
# Install cpanm (most recent)
cpan App::cpanminus
Then you can install any Perl package you like, as for example in the OP, using cpanm:
cpanm Net::TCP::Server
Sometimes (as noted above) Cygwin may fail certain tests. For example, when using IPv6 on a machine only configured with IPv4, or when your windows firewall is blocking some tests, etc. To attempt to install anyway, try to use the force flag; -f.
cpanm -f Net::TCP::Server
I'm a C/C++/java unix geek by trade, but now I have to write a perl program in windows. So I've got cygwin, eclipse with EPIC installed, and simple test programs run. I do not have a unix machine available to me that I can run eclipse on.
You should be able to run Eclipse with EPIC right under Windows without Cygwin. I like Cygwin for many things, but it isn't exactly a very stable platform. Eclipse runs as a Java program, so all you have to do is make sure Java is installed on your PC. There is even a pre-built Eclipse package.
You can also get a decent Perl that runs right under Windows. Either ActivePerl or Strawberry Perl. Either one will work although many Unix heads prefer Strawberry Perl because it comes with the same MIGW environment that Cygwin has and many feel it's more compatible with the Unix Perl brethren. However, ActiveState Perl can use the Perl Package Manager (PPM) that contains pre-built modules. Unfortunately, the module you want isn't available via PPM.
But I need to use Net::TCP::Server and I can't figure out how to install it. It doesn't appear to be part of the cygwin perl install, and I don't want to spend 5 days learning the world of perl and cpan and perl configuration. I just want to write my program.
Installing from CPAN is really quite simple. The first time you run CPAN, it should pretty much configure itself. Then, to do an install, you run cpan install Net::TCP::Server and that should be it. However, I've tried on several Mac, Unix, and Linux machines, and I can't get it to work. So, this isn't a Windows problem as much as a problem with this module. It is fairly old, and might not work well in newer versions of Perl. You might have to force the install over test's objections.
Maybe you can use one of the already installed IO modules that come with Perl instead. That'll save you a boatload of trouble because the required modules are part of Perl's existing package.
Despite Cygwin's "problems," I use it regularly whenever I have to use Windows. I would recommend first installing a separate installation of Perl using perlbrew so that you won't interfere with Cygwin's copy of Perl in case something bad happens since Cygwin does not enforce root-user policy. In cygwin shell, type
\curl -L http://install.perlbrew.pl | bash
This should walk through the installation for perlbrew and set it up in one of your executable path. Next type
perlbrew init
perlbrew install --force stable
perlbrew switch stable
Wait a bit while a mint Perl is compiled. For unknown reason, Perl can only pass 99.23% of the core module tests on Cygwin (at least on my machine),hence the --force flag). My experience is that it mostly have something to do with handling of device files, like ports and pipes. I am unaware of people trying to resolve the issue as it seems like a Cygwin problem. Although it has not presented much problem for me with general system and web programming tasks. The module testing routines will fail if any problem exists so I am not fretting over it.
Next step is to install cpanm (cpanminus), type
perlbrew install-cpanm
From here on out, to install any library from CPAN, just type
cpanm [library::name1] [library::name2]
cpanm makes it trivial to install any Perl modules. You can even install from your local directory instead of CPAN.
Your mileage may vary, but I had a lot of trouble until I realized that Strawberry perl had a lot of bin folders in my PATH, and when I changed my .bashrc to export only a very simple PATH=/bin:/usr/bin:/usr/local/bin, Cygwin's perl installation's cpan started working beautifully. I used local:lib as Cygwin doesn't support sudo. Before it got into a bad loop saying "Press SPACE and ENTER to exit Patch" over and over.
I'm running Windows 7 64 bit, which seems to be part of the problem. At first my cpan would hang when I would try to install CPAN from the shell prompt.
I tried restarting my computer, and a variety of attempts to use rebaseall and peflagsall from ash- even starting a new base for the dll's (the command was something suggested on a cygwin mailing list- something like rebaseall -vb 0x730000).
Should I just uninstall Cygwin and try to do a total reinstall? I have all the dependencies that cpan should need (i.e. gcc-4).
I'm getting pretty desperate here- I'm getting error messages that talk about failed dlls if I try to use modules installed from CPAN (specifically, JSON::XS).
Any help you could offer would be fantastic.
Thanks!
The complaining about missing dlls when installing is a known bug I believe, and appears for a lot of modules. Most modules are still installed and still work however. In my experience, you need to force install most modules as well, as there is almost always some test that fails.
While I personally prefer perl from the cygwin environment, there is one good reason for installing Strawberryperl; the need for 64 bit support which cygwin does not support. If you are going to work with large XML data structures using XML::Simple for instance, the 1.5-2GB that 32-bit Windows support will not take you far, and Strawberryperl will come to your rescue. And thanks to perl portability, and apart from keeping two sets of perl's installed on the same computer, the is no problem doing development using cygwin, and then running it "in production" using 64-bit Strawberryperl.
Are you installing cygwin and then building Perl on top of that? You will be far more successful if you use Strawberry Perl which comes with its own cygwin environment that will allow you to build and install most CPAN modules if you need them
I suspect the problem you're hitting is the difference between the regular shell (which will normally be bash and give you a $ prompt on Cygwin) and the cpan shell (which will give you a prompt like cpan[1]>).
In the cpan shell, install CPAN will refresh a bunch of Perl scripts from the CPAN repository. From a bash shell, install CPAN just doesn't make sense: install is a program for installing packages you've just built; it has nothing in particular to do with Perl or with how you install packages on Cygwin.
You can enter the CPAN shell by running cpan at bash shell prompt. But I don't think that's what you need. What you actually want to do is just run the following:
cpan JSON::XS
