Can't compile XS code

[nglenn]

I am using Windows 7 64 bit, Strawberry Perl 5.16.1. I have another computer with seemingly the same configuration that does not have the same problem.

I was trying to compile a module with XS code and it spat all sorts of compilation errors at me. Since I had heard that 5.16 had shipped with the developer release of MakeMaker, I thought that might be the problem, so I did tried to install the last release of MakeMaker (6.62). However, I got the same errors during the testing. Can anyone help me figure out why I have the errors given below during testing of MakeMaker, more specifically during any XS compilation?

EDIT: The problem was that I had another distribution of MINGW on my path. Once that was removed, everything worked smoothly.

undefined reference to `_imp__Perl_get_context'

I would think that symbol (and all of the others mentioned) should have been resolved by C:\strawberry\perl\lib\CORE\libperl516.a, to which you are apparently linking.
Run objdump -t C:\strawberry\perl\lib\CORE\libperl516.a >dump.txt and check that `_imp__Perl_get_context' can be found in the output that was sent to dump.txt.
Looking at my build of Strawberry 5.12, it looks like those symbols might be prefixed by 2 (not one) underscores. However, I don't know if such a discrepancy would matter anyway.

What does perl -V output. This is strange ... it shouldn't be happening.

Perhaps simply re-installing Strawberry Perl might fix the problem.

Cheers,
Rob

objdump gives me a whole bunch of:

perl -V gives me:

objdump: dknisxxxxx.o: File format not recognized

Then that's your problem ... or at least *one* problem that needs to be fixed.

Could that libperl516.a that's being found be a 32-bit version of libperl516.a ? The error messages from objdump would fit such a scenario.
Compare it to the libperl516.a that's on the other machine you mentioned. They should be identical (obviously), right down to the Digest::MD5 signatures, if they're the same builds of Strawberry Perl.

Afterthought: If that libperl516.a is 64-bit, then another possibility is that you've just run a 32-bit version of objdump on it. That would also fit the objdump errors you reported.

It has just dawned on me that the compilation failures quoted are occurring during 'dmake test' and not 'dmake' as I had assumed. (My mistake - it's pretty obvious that 'dmake test' is under way.)

Normally, by the time we get to 'dmake test', all compilation has been done - and it's uncommon to see compilation being carried out during the 'dmake test' stage. What module is it (in your original post) that you are trying to build ?
