I have installed perl-5.8.9, mod_perl-2.0.7, Embperl-2.3.0 and httpd-2.2.22. And while starting apache, I get the error like the following (broken into multiple lines for readability):
httpd: Syntax error on line * of ../conf/httpd.conf:
Cannot load ../Apache2/mod_perl.so into server:
libperl.so: cannot open shared object file:
No such file or directory
And by doing ldd ../Apache2/mod_perl.so, I got the output like
linux-gate.so.1 => (0x00735000)
libperl.so => not found
libnsl.so.1 => /lib/libnsl.so.1 (0x005e5000)

[The question could usefully be moved to the Unix & Linux SE.]
You appear to have installed not-quite-compatible packages, or one or more packages did not install properly, or the installation instructions are missing a step, or the dynamic linker defaults are not as expected.
libperl is (unsurprisingly) part of perl. On some platforms a normal perl default build will create only the libperl.a static library, though it is possible to create a dynamic library libperl.so instead, or both. Some people favor the .so approach, though it can have some performance overheads.
The most likely causes of your problem are:
the installed perl has only static libperl.a, but mod_perl was built against a dynamic perl with libperl.so
the perl package installed libperl.so somewhere the dynamic linker doesn't look
Addressing cause #1 means finding different, compatible packages (or perhaps a combined package).
If it's #2, you should be able to locate libperl.so (somewhere like /usr/local/lib/perl5/5.8.9/mach/CORE/), or just run ldd /usr/local/bin/perl (wherever the new perl binary installed to) to see if it knows where it is.
Before you try any of the changes suggested below, just run ldconfig as root then try again, in case that fixes it.
If you find libperl.so under the new perl installation directory, then you can copy that file to your Apache lib/ sub-directory as Apache should be built (with an ELF RPATH) to include that directory in the library search path. If you find it under /usr/local/lib then you should modify your default linker configuration (/etc/ld.so.conf) to include that directory, and refresh (run ldconfig as root).
Your platform is evidently Linux, but you don't state the type and origin of packages, or whether it's a source build, so I can't be more precise...
I'm slightly suspicious that something didn't install properly because the conventional place for Apache modules is within the modules/ sub-directory, not directly in the ServerRoot.

How do I install Helm (https://hackage.haskell.org/package/helm) on Windows 7 (64-bit)?
(Update: I had posted a lot of error messages here, but I've moved them to my answer to not clutter up the question.)
Installation for Windows 64-bit:
I'm including error messages, for if you follow all the steps up to that point and then just try to install directly. This is a conglomeration of a bunch of ad-hoc steps from following many different posts. Any simplification would be appreciated!
Note: Do all work in directories without spaces. I'm doing all work in C:/PF; modify this to your directory.
Download MSYS2-x86_64 from https://msys2.github.io/ and install it. Cabal install cairo (or helm) will give something like:
Configuring cairo-0.13.1.0...
setup.exe: Missing dependencies on foreign libraries:
Missing C libraries: z, cairo, z, gobject-2.0, ffi, pixman-1, fontconfig,
expat, freetype, iconv, expat, freetype, z, bz2, harfbuzz, glib-2.0, intl,
ws2_32, ole32, winmm, shlwapi, intl, png16, z
Download C libraries. In MINGW64 (NOT MSYS2 - I had trouble with MSYS2 at random stages in the process), use the package manager:
pacman -Ss cairo
to search for the Cairo package. You'll find "mingw64/mingw-w64-x86_64-cairo", so install that:
pacman -S mingw64/mingw-w64-x86_64-cairo
*.pc files should have been added to C:\PF\msys64\mingw64\lib\pkgconfig and C:\PF\msys64\usr\lib\pkgconfig. (pkg-config needs to be able to find these files. It looks in PKG_CONFIG_PATH, which by default should have the lib/pkgconfig folder above. Moving the file here is easiest. See Can't install sdl2 via cabal) If you get
The pkg-config package ... version ... cannot be found
errors then check your *.pc files.
Repeat with other required libraries, like atk
pacman -S mingw64/mingw-w64-x86_64-atk
(I don't know the complete list, but error messages later on will let you know what to get.)
Get the development files for these libraries (as suggested by How to install cairo on Windows). Most of them are bundled up at http://ftp.gnome.org/pub/gnome/binaries/win64/gtk+/2.22/. Unzip.
Copy files (.a, .dll.a) in lib to C:\PF\msys64\mingw64\lib. Copy the pkgconfig folder, which contains the .pc files.
Copy files in include to C:\PF\msys64\mingw64\include.
Add C:\PF\gtk+-2.22.1\bin to the path.
(2) and (3) might be redundant. I don't know - I did them both.
At this point you can probably do "cabal install cairo". (Warning: if your end goal is something else, you may not want to "cabal install" intermediate packages, see https://wiki.haskell.org/Cabal/Survival#Issue_.232_--_Not_installing_all_the_packages_in_one_go.)
See (4) for the syntax in specifying extra-include-dirs and extra-lib-dirs (but if you copied the files above this shouldn't be necessary),
Any time you get
Missing (or bad) header file
check to see you copied the *.h files to mingw64\include and/or add the include folder to the PATH. Use cabal install -v3 to get verbose error messages if the problem persists.
If you get something like
cairo-0.13.1.0: include-dirs: /mingw64/include/freetype2 is a relative path
which makes no sense (as there is nothing for it to be relative to). You can
make paths relative to the package database itself by using ${pkgroot}. (use
--force to override)
try --ghc-pkg-options="--force" (as mentioned at https://github.com/gtk2hs/gtk2hs/issues/139).
Get SDL. Otherwise you'll get
configure: error: *** SDL not found! Get SDL from www.libsdl.org.
If you already installed it, check it's in the path. If problem remains,
please send a mail to the address that appears in ./configure --version
indicating your platform, the version of configure script and the problem.
Failed to install SDL-0.6.5.1
Follow the instructions in (2) to get sdl/sdl2 libraries. (See instructions here Installing SDL on Windows for Haskell (GHC).)
The new version helm-0.7.1 requires sdl2, but there are other dependency issues with helm-0.7.1 as of writing. Download SDL from http://sourceforge.net/projects/msys2/files/REPOS/MINGW/x86_64/ (direct download link to newest version as of writing http://sourceforge.net/projects/msys2/files/REPOS/MINGW/x86_64/mingw-w64-x86_64-SDL-1.2.15-7-any.pkg.tar.xz.sig/download), unzip. "cabal install sdl" gives
* Missing (or bad) header file: SDL/SDL.h
* Missing C library: SDL
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
so we specify where the dirs are (change the name depending on where you extracted sdl to)
cabal install sdl --extra-include-dirs=C:/PF/sdl\include --extra-lib-dirs=C:/sdl/lib
If you got SDL2 (http://libsdl.org/download-2.0.php) (for a newer version of Helm): there is a fatal bug that hasn't been fixed in the release version. (If you don't fix it, cabal install -v3 things which depends on it will give error
winapifamily.h: No such file or directory
("winapifamily.h: No such file or directory" when compiling SDL in Code::Blocks) Download https://hg.libsdl.org/SDL/raw-file/e217ed463f25/include/SDL_platform.h, replace the file in the include folder and in C:/PF/msys64/mingw64/include/SDL2.
Download gtk2hs from http://code.haskell.org/gtk2hs and run
the following
cd gtk2hs/tools
cabal install
cd ../glib
cabal install
cd ../gio
cabal install
cd ../pango
cabal install --ghc-pkg-options="--force"
(Maybe you have already installed glib and gio from before? I did this step because normal install of Pango caused an error for me (https://github.com/gtk2hs/gtk2hs/issues/110)
pango-0.13.1.0: include-dirs: /mingw64/include/freetype2 is a relative path
which makes no sense (as there is nothing for it to be relative to). You can
make paths relative to the package database itself by using ${pkgroot}. (use
--force to override)
Once the Helm developers get things updated you should be able to do "cabal install helm" but right now there seem to be dependency issues. For me, cabal automatically tries to install helm-0.4 (probably because 0.4 didn't give upper bounds on dependencies, while newer versions do. You could try "cabal unpack"ing and deleting the upper bounds...). Then
cabal unpack helm-0.4
Installing gives an error because "pure" got moved to Prelude. Open helm-0.4\src\FRP\Helm\Automaton.hs and change line 17:
import Prelude hiding (id, (.), pure)
Now
cabal install
Try to compile and run a program using Helm
(This is 0.4 - look on the website for a newer sample if you tried a newer Helm)
import FRP.Helm
import qualified FRP.Helm.Window as Window
render :: (Int, Int) -> Element
render (w, h) = collage w h [filled red $ rect (fromIntegral w) (fromIntegral h)]
main :: IO ()
main = run $ fmap (fmap render) Window.dimensions
If you get an error about a missing .dll (sdl.dll), find it in a bin/ folder and add the folder to your PATH (or copy it to somewhere on your path).
Instead of adding or modifying files in the directory where the sources of a Perl module are unpacked, I would like to build everything in a separate directory. Is this easily achievable with a fairly standard Makefile.PL that uses ExtUtils::MakeMaker? (By easy, I mean something like one or a few command line parameters.) If no, does any of the other build systems support this?
Update / Reason: The Perl module is a binding to a library whose build system is autoconf/automake/libtool-based. The Perl module is shipped together with this library and calling make in the top directory eventually also builds the Perl library. I am interested in building the entire project in a separate build tree. At the moment I do something similar to what runrig suggested, only using symlinks. (cp -sru $(srcdir)/. $(builddir)/.). This has worked so far, but if there is a more elegant solution, I'd like to read about it.
MakeMaker already copies the sources and builds them in a separate directory (that's what blib/ is). You can control the build location with the INST_* set of arguments to WriteMakefile(). This example changes the location from blib/ to foo/.
INST_ARCHLIB => "foo/arch",
INST_LIB => "foo/lib",
INST_BIN => "foo/bin",
INST_SCRIPT => "foo/script",
INST_MAN1DIR => 'foo/man1',
INST_MAN3DIR => 'foo/man3',
In addition you have to tell MakeMaker to cleanup the new build directory.
clean => {
FILES => 'foo'
},
See "Determination of Perl Library and Installation Locations" in the ExtUtils::MakeMaker docs for more info.
cp -R Module-Directory-0.01 Module-Directory-0.01.copy
cd Module-Directory-0.01.copy
perl Makefile.PL
make
make test
...etc.
I ended up using symlinks:
The library to which the Perl module provides bindings uses an
autoconf/automake/libtool-based build system. Makefile.PL is
generated from Makefile.PL.in by configure. Makefile.PL
generates Makefile-pl (Makefile has already been taken by
autoconf/automake).
This is the relevant part of Makefile.am:
all: Makefile-pl src_deps
$(MAKE) -f Makefile-pl
Makefile-pl: Makefile.PL
perl Makefile.PL INSTALLDIRS=$(INSTALLDIRS) PREFIX=$(prefix)
I changed the second target to:
Makefile-pl: Makefile.PL
-[ $(srcdir) != $(builddir) ] && cp -rsu $(abs_srcdir)/. $(builddir)/.
perl Makefile.PL INSTALLDIRS=$(INSTALLDIRS) PREFIX=$(prefix)
This should work as long as building or installing the Perl module
does not result in any files being modified in-place.
I'm working on installing a perl module (not using CPAN) on a Linux machine. When I run the command:
perl Build.PL
I get the following error:
ERROR: Missing required field 'dist_abstract' for metafile
Could not get valid metadata. Error is: Invalid metadata structure.
Errors: Missing mandatory field, 'abstract' (abstract) [Validation: 1.4],
value is an undefined string (abstract) [Validation: 1.4]
at /usr/local/share/perl5/Module/Build/Base.pm line 4559
Could not create MYMETA files
I've tried Googling bits and pieces of this error but haven't found any solutions. Just looking for a clue as to what might be causing this error.
Here's a link to a zip file containing the files required to install it:
https://oncourse.iu.edu/access/content/user/brilewis/Filemanager_Public_Files/DataDownloader.zip
First at all please make sure you have package Module::Build installed.
You need ungzip few gzipped files in this package. I don't realize why author gzipped them:
gzip -d *.gz
I really don't know why author archived each install file. It looks like some mistake to me.
Than you can install all dependencies (this module requires some):
./Build installdeps
And then finally install module itself:
./Build
./Build test
./Build install
However I must warn you that this module packaged in a bit strange way and there's no guarantee it works.
The NAME section of the module does not have a - in it, e.g.,
=head1 NAME
Foo::Bar implements a Foo framework.
will fail, but if you make it
=head1 NAME
Foo::Bar - implements a Foo framework.
then it will work.
Do you have root access on your machine? Can you use the cpan utility to build and install your module. Using cpan is fairly straight forward:
$ cpan
After that, it will do a lot of configuration, simply take the default values. When it finishes, it'll come to a cpan> prompt. All you have to do there is type this:
cpan> install Module::Name
Where Module::Name is the module you're trying to install. Check the CPAN archive to get the name of your module.
If there are any dependencies, CPAN will ask if you want to download and install those. Say Yes, and CPAN will install the dependencies, then your module.
Using cpan is the best way to install third party modules you find in the CPAN archive. It takes care of all the dependencies, testing, and building for you.
Try installing through CPAN, and then see if you still have your issues.
I am trying to setup a directory that contains Perl modules that should be set aside to not interfere with a production system.
This works OK, with modules that use Module::Install. I just specify a "lib" option and all is well. Now I tried and tried and I simply cannot make this happen with Module::Build. For instance, this command:
./Build install --lib /foo
Will install the module in "/foo/share/perl/5.10.0".
How can I get rid off the "share/perl/5.10.0" part?
PS: Yes, I have taken a long look at the documentation and found some promising sections, but I simply must admit that I seem to be too stupid to grok them.
See install_path. It looks like (I haven't tried) you can either put in .modulebuildrc or specify on the command line all of the path options:
./Build install --install_base $CUSTOMPERLSTUFF \
--install_path lib=$CUSTOMPERLSTUFF/lib \
--install_path arch=$CUSTOMPERLSTUFF/lib
I think your best chance is with install_base. From the doc:
install_base
You can also set the whole bunch of installation paths by supplying the install_base parameter to point to a directory on your system. For instance, if you set install_base to "/home/ken" on a Linux system, you'll install as follows:
lib => /home/ken/lib/perl5
arch => /home/ken/lib/perl5/i386-linux
script => /home/ken/bin
bin => /home/ken/bin
bindoc => /home/ken/man/man1
libdoc => /home/ken/man/man3
binhtml => /home/ken/html
libhtml => /home/ken/html

*** Version Mismatch ***
You are attempt to build XML::Xerces-2.7.0-0 using Xerces-C-2.8.0,
this will most likely fail, so I am aborting.
You must use Xerces-C-2.7.0
Here's a general rule: any environment variable that is named something like "ROOT" is asking for a directory, not a file.
However, it does not appear that you have installed the Xerces library, which is necessary before you install the perl module. I'll quote some portions of the output you provided, as the hint you missed as to what to do next:
"...These instruct me how to locate the Xerces header files, and the Xerces dynamic library..."
"Without these I cannot find the config.status file that was used to
build your Xerces-C library"
So, did you install Xerces-C? You'll have much better results installing the Perl module after that.
Did you try using the PPM to install XML::Xerces?
