ghc 6.12 dropped separate utf8-string packages since most of its functionality is implemented in stock modules. In particular System.Environment.UTF8 does not exist anymore.
But the following does not work for me if an arg is a non-ascii string:
import System.Environment
main = do
[arg] <- getArgs
putStrLn arg
I get some garbage at my terminal.
It is a bug, see
http://hackage.haskell.org/trac/ghc/ticket/3309
(I assume you mean System.Environment, not System.Environment.UTF8)
The workaround could be to cabal install utf8-sting and use System.Environment.UTF8

I'm currently facing a problem with this team of 4.
Using binaries I downloaded on kiska's site. I'm able to compile cobol to C and run it with cobcrun or compile it to an executable. However I can 't get opencobol to find the postgres commands.
Here is the strat of my cobol script :
identification division.
program-id. pgcob.
data division.
working-storage section.
01 pgconn usage pointer.
01 pgres usage pointer.
01 resptr usage pointer.
01 resstr pic x(80) based.
01 result usage binary-long.
01 answer pic x(80).
procedure division.
display "Before connect:" pgconn end-display
call "PQconnectdb" using
by reference "dbname = postgres" & x"00"
by reference "host = 10.37.180.146" & "00"
returning pgconn
end-call
...
the call PQconnectdb fail with module ont found : PQconnectdb
I noticed that if i rename the libpq.dll the error message change to can't find entry point. So at least I'm sure it can get my dll.
After digging into the code of the call method of the libcob library. I found it it was possible to pre load some dll using an environment variable COB_PRE_LOAD but sitll no results.
Here is what look the script to compile the cobol :
call "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\vcvarsamd64.bat"
set COB_CONFIG_DIR=C:\OpenCobol\config
set COB_COPY_DIR=C:\OpenCobol\Copy
set COB_LIBS=%COB_LIBS% c:\OpenCobol\libpq.lib
set COB_LIBRARY_PATH=C:\OpenCobol\bin
set COB_PRE_LOAD=C:\OpenCobol\libpq.dll
#echo on
cobc -info
cobc -free -o pgcob -L:"C:\OpenCobol" -llibpq.lib test_cobol\postgres.cob
call cobcrun pgcob
I don't see anything missing, I'm using the 64-bit binaries from kiska's site and use the 64-bit cl.exe from Visual Studio, Postgres is a 64 bit version too (checked with dependencyChecker).
I even tryed to compile the generated C from Visual Studio, same result, but I may miss something, I'm pretty rotten in C and never really had to manage DLL or use Visual Studio.
What am I missing ?
COB_PRE_LOAD doesn't take any path or extension, see the short documentation for the available runtime configurations. I guess
set COB_LIBRARY_PATH=C:\OpenCobol\bin;C:\OpenCobol
set COB_PRE_LOAD=libpq
Will work. You can omit the C:\OpenCobol\bin if you did not placed any additional executables there.
If it doesn't work (even if it does) I'd try to get the C functions resolved at compile time. Either use
CALL STATIC "PQconnectdb" using ...
or an appropriate CALL-CONVENTION or leave the program as-is and use
cobc -free -o pgcob -L"C:\OpenCobol" -llibpq -K PQconnectdb test_cobol\postgres.cob
From cobc --help:
-K generate CALL to <entry> as static
In general: the binaries from kiska.net are quite outdated. I highly suggest getting newer ones from the official download site or ideally build them on your own from source, see the documentation for building GnuCOBOL with VisualStudio.
I released Net::NSCAng::Client a while ago and am getting a lot of test failures on OpenBSD. The reason for that is that the NSCAng protocol uses OpenSSL in preshared-key mode (RFC4279), something the folks at LibreSSL (default on OpenBSD now) have ripped out. However, they seem to have been hell-bent on doing this the most intransparent way: the include files have all the functions defined, just the shared library is missing the corresponding symbols, so compilation works fine but the tests fail.
There is a compatibility package on OpenBSD called eopenssl, and by testing for this first in Makefile.PL (using ExtUtils::PkgConfig) I can make it work if the compatibility library is installed. If it isn't, things still fail.
I could check for the CPP symbol OPENSSL_NO_PSK, but as the includes always come from LibreSSL, this fails even if linking with eopenssl would work fine. The only idea I have left is to try and have a test program run as part of the compilation phase as autoconf does it. Is that even possible with ExtUtils::MakeMaker (or something else -- I wouldn't mind switching the build system if necessary)?
It's easy to write feature tests with Devel::CheckLib. Something like the following can be used to check for the presence of function your_func (in Makefile.PL):
my $your_func_exists = check_lib(
header => 'your_header.h',
function => 'return your_func ? 1 : 0;',
);
If you simply want to abort compilation if the function is missing:
check_lib(
...
) or warn('your_func is missing'), exit;
Exiting with 0 should avoid a CPAN Tester's 'FAIL' report.
I am trying to run ReSharpers command line tool InspectCode.exe. It's running fine doing it's job with the expected output.
However after my earlier attempt to get plugins to work, this time with the new version it is supposed to be supported. There is a switch in the command line interface that allows to specify the extension you want to use.
/extensions (/x) – allows using ReSharper extensions that affect code analysis. To use an extension, specify its ID, which you can find by opening the extension package page in the ReSharper Gallery, and then the Package Statistics page. Multiple values are separated with the semicolon.
But I cannot get it to work properly. I cannot even provoke any reaction to the /x switch at all. No matter how or what I pass, I get no feedback from the executable and the output is identical. I don't even get an error message when passing obvious garbage.
I tried the following commandlines for the exact same result:
inspectcode.exe /o="rcli.xml" /swea /x="ReSharper.StyleCop" "my.sln"
inspectcode.exe /o="rcli.xml" /swea /x=ReSharper.StyleCop "my.sln"
inspectcode.exe /o="rcli.xml" /swea "my.sln"
inspectcode.exe /o="rcli.xml" /swea /x=ABCDEFG "my.sln"

What am I doing wrong? How to get extensions to work?
I already tried the R# forums, but it took them more then 24h to approve my post and so far I'm not sure someone else even read it.
Unfortunately, the support for extensions was dropped in 9.0 due to the refactorings in the "ReSharper platform". I hope that JetBrains will bring it back soon.
See RSRP-436208.
This is a late answer that might help future readers (like myself). Currently inspectcode.exe will automatically look for and use any NuGet packages that are in the same folder as the executable (source).
Example for CleanCode extension:
if you have a R# instance on some machine and install the extension, it will be placed in C:\Users\{user}\AppData\Local\JetBrains\plugins\MO.CleanCode.5.6.15
copy MO.CleanCode.5.6.15.nupkg and paste it next to inspectcode.exe
when running inspectcode with verbosity = VERBOSE, the extension should appear in the Zones list:
$cmd = "..\JetBrains.ReSharper.CommandLineTools.2019.3.4\inspectcode.exe"
$outputFile = "..\Output\$($outputName).xml"
& $cmd -o="$outputFile" $sln --verbosity=VERBOSE

If my script foo.py is:
import scipy
Then run:
python pyinstaller.py --onefile foo.py
When I launch foo.exe I get:
WARNING: file already exists but should not: C:\Users\username\AppData\Local\Temp\_MEI86402\Include\pyconfig.h
I've tested a few versions but the latest I've confirmed is 2.1dev-e958e02 running on Win7, Python 2.7.5 (32 bit), Scipy version 0.12.0
I've submitted a ticket with the Pyinstaller folks but haven't heard anything yet. Any clues how to debug this further?
You can hack the spec file to remove the second instance by adding these lines after a=Analysis:
for d in a.datas:
if 'pyconfig' in d[0]:
a.datas.remove(d)
break
The answer by wtobia# worked for me. See https://github.com/pyinstaller/pyinstaller/issues/783
Go to C:\Python27\Lib\site-packages\PyInstaller\build.py
Find the def append(self, tpl): function.
Change if tpl[2] == "BINARY": to if tpl[2] in ["BINARY", "DATA"]:
Expanding upon Ilya's solution, I think this is a little bit more robust solution to modifying the spec file (again place after the a=Analysis... statement).
a.datas = list({tuple(map(str.upper, t)) for t in a.datas})
I only tested this on a small test program (one with a single import and print statement), but it seems to work. a.datas is a list of tuples of strings which contain the pyconfig.h paths. I convert them all to lowercase and then dedup. I actually found that converting all of them all to lowercase was sufficient to get it to work, which suggests to me that pyinstaller does case-sensitive deduping when it should be case-insensitive on Windows. However, I did the deduping myself for good measure.
I realized that the problem is that Windows is case-insensitive and these 2 statements are source directories are "duplicates:
include\pyconfig.h
Include\pyconfig.h
My solution is to manually tweak the .spec file with after the a=Analysis() call:
import platform
if platform.system().find("Windows")>= 0:
a.datas = [i for i in a.datas if i[0].find('Include') < 0]
This worked in my 2 tests.
A more flexible solution would be to check ALL items for case-insensitive collisions.
I ran the archive_viewer.py utility (from PyInstaller) on one of my own --onefile executables that has the same error and found that pyconfig.h is included twice:
(31374007, 6521, 21529, 1, 'x', 'include\\pyconfig.h'),
(31380528, 6521, 21529, 1, 'x', 'Include\\pyconfig.h'),
(31387049, 984, 2102, 1, 'x', 'pytz\\zoneinfo\\CET'),
Sadly though, I don't know how to fix it.

this question is a follow up to:
What's the search order in perl's include path when a module is loaded posted a while back but that remained unanswered.
I have 2 versions (1.22 and 1.25) of the module IO installed in two separate folders:
/some_path/lib/perl5/x86_64-linux-thread-multi/ (for IO.pm version 1.25)
and
/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/ (for IO.pm version 1.22)
The #INC list looks like:
/some_path/lib/perl5/x86_64-linux-thread-multi/
/usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/
/usr/lib/perl5/site_perl/5.8.8/
/usr/lib/perl5/site_perl/
/usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/
/usr/lib/perl5/vendor_perl/5.8.8/
/usr/lib/perl5/vendor_perl/
/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/
/usr/lib/perl5/5.8.8/
.
When i try perl -e 'use IO', perl returns the following error message:
IO object version 1.22 does not match bootstrap parameter 1.25 at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/DynaLoader.pm line 253.
which suggests that the IO module version 1.22 is used instead of IO version 1.25 even though the IO version 1.25 should be located first.
Any idea why that is?
You have a bad install of IO.
perl is finding 1.25's IO.pm in /some_path/lib/perl5/x86_64-linux-thread-multi/ as intended, but the first auto/IO/IO.so it finds is 1.22's (in /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/?)
