These should really be user definable... I'm just going to edit the files in inc/ -- but it'd be handier (in terms of upgrades) if I could just set it from the Makefile. print $ch qq{#include <$header>\nint main(void) { return 0; }\n}; print $ch "int main(void) { return 0; }\n"; I need to do something besides return 0 to check for the right library version. -- If riding in an airplane is flying, then riding in a boat is swimming. 110 jumps, 45.0 minutes of freefall, 86.2 freefall miles.
The subject appears to be truncated -- what is it that you think needs to be customizable?

Yeah, the subject isn't what I intended, but the body was... I need to check for the existence of a certain function. I did this in my inc/ by commenting out your $cfile (tempfile) and using my own... I'd prefer a config setting I could use from Makefile.PL or support for checking for functions or something. -- If riding in an airplane is flying, then riding in a boat is swimming. 110 jumps, 45.0 minutes of freefall, 86.2 freefall miles.

Would it be sufficient to be able to provide your own body for main()? Then you could pass it something like ... if(function1() && function2() && library_version() > 1.23) { return 0; } else { return 1; } to check that function 1 and function2 exist, and that library_version is high enough. It would be specified something like ... check_lib_or_exit( lib => 'jpeg', header => 'jpeglib.h', checkfunction => 'C code goes here' ); Then finally, we need to run the generated executable and make sure it returns the right value.

This is almost fine for my purposes. I just want to see if the function is *there*. Others may need more, so to fix it in the general sense, it does make sense to check the return values and things. I also need to specify an #include though. Perhaps that carries over from the header setting? -Paul -- If riding in an airplane is flying, then riding in a boat is swimming. 110 jumps, 45.0 minutes of freefall, 86.2 freefall miles.

If the function ain't there, then it should fail at link-time. Show quoted text

Yes.
Feature added (I think!) in 0.699_001, will bump to 0.7 once CPAN-testers results are in.
