use Inline C => Config => LIBS => '-L/HASP/perltestP -llibhasp_linux.a';

I think that's wrong, unless the library is called something like libhasp_linux.a.a. Or is the linker smart enough to know that the '.a' should be dropped ? I would change it to:

use Inline C => Config =>
    LIBS => '-L/HASP/perltestP -llibhasp_linux',
    BUILD_NOISY => 1;
[download]

and check the output for any messages that tell you that no library was found for -llibhasp_linux. When you build the C program do you provide an -llibhasp_linux.a argument on the command line (or is it simply -llibhasp_linux ) ? I would expect that whatever argument works on the command line should also work for the 'LIBS' config option.

Note: The BUILD_NOISY option means that you'll see any warnings that are emitted during the build process. Without it, relevant warnings often don't appear.

Cheers,
Rob

At the moment I don't think I can build anything with XS

What error messages do you get when you try to build a module (other than Inline) that includes XS code. (It's generally easier to diagnose error messages in relation to XS modules - rather than trying to diagnose the errors that Inline spits out.)

Mind you, I'm pretty much at a loss to see why you should be having such difficulty. The output of your 'perl -V' is very similar to mine for linux. My configure args were '-des' and the '-Wdeclaration-after-statement' is missing on my build. Apart from that I can't spot a significant difference. I don't think the '-des' vs '-de' difference could amount to much ... I have no idea what the '-Wdeclaration-after-statement' stuff is about (and whether it could be relevant).

Anyway, if you like to post the results of trying to build an XS module (such as Math::FFT), then I'll certainly take a look. (Whether I'll be able to provide some useful assistance is another question .... looking more'n'more unlikely :-)

Cheers,
Rob
