Devel::Declare for cygwin; "undefined reference to '_hook_op_check'"

[Boldra]

I'm trying to install Devel::Declare to use MooseX::Declare on cygwin perl 5.10 and hitting a g++ compiler error.

Checking if your kit is complete...
Looks good

I have never had a good relationship with C compilers. Can someone suggest a way forwards? Does anyone know of a cygwin binary package I can use? Or what I could google for?

I also had some problems with the permissions, +x was missing on "/usr/lib/perl5/5.10/i686-cygwin" and some subdirectories. I fixed this, and this doesn't look like a permission problem any more.

Thanks!

I don't know anything about this distro, but could that be the reason for the linking failures ?
If libCheck is really required, then the fact that it can't be found is certainly not "harmless".

Upgrade ExtUtils::Depends , reinstall (critical) B::Hooks::OP::Check , then install Devel::Declare

[Boldra]

ExtUtils::Depends was at 0.302, the latest I could find on CPAN, and from your suggestion I've tried reinstalling B::Hooks::OP::Check both via cpan> force install ... and downloading the tgz and installing with make install, but in the end I'm still getting the same error.

You certainly sound like you know what your talking about, so I'd be very happy if you had any further suggestions!

Try uninstalling, then reinstalling. #40471: Won't link against hook_op_check on Strawberry 5.10

[Anonymous Monk]

If there are still people needing this help (I did), here is THE fix: start up cygwin setup.exe. search for check. You will (should) find one in Devel. It is: check: unit test framework for C Install that and your build problems for this will go away.

1. cpanm App::pmuninstall
2. pm-uninstall ExtUtils::Depends B::Hooks::OP::Check
3. cpanm ExtUtils::Depends
4. cpanm -v B::Hooks::OP::Check

capture the full path of CORE/cygperl5_14.dll
capture the full path of B/Hooks/OP/Check/Check.dll

5. cpanm --look Devel::Declare --mirror http://search.cpan.org/CPAN
6. perl Makefile.PL
7. make

You will see error from the g++ command. copy it and modify it like below and run it.

g++-4 --shared -Wl,--enable-auto-import -Wl,--export-all-symbols -Wl,--enable-auto-image-base -L/usr/local/lib -fstack-protector Declare.o -o blib/arch/auto/Devel/Declare/Declare.dll \
## Replace with full path
--> CORE/cygperl5_14.dll \
--> B/Hooks/OP/Check/Check.dll

Press Enter without Error then you are good to move forward to test and install

Finally,

make test
make install
