Hello again, I'm not quite sure if this is a bug or just a misfeature of OSX, but I'm having trouble getting the C client API to work correctly. Please see the attached Sample.xs and Sample.pm for the (simplified) code I'm using. It compiles without errors, but when I attempt to load the module, the following error happens: $ /opt/local/bin/perl -Iblib/lib -Iblib/arch -MSample Can't load 'blib/arch/auto/Sample/Sample.bundle' for module Sample: dlopen(blib/arch/auto/Sample/Sample.bundle, 1): Symbol not found: _math_int128_c_api_SvU128 Referenced from: blib/arch/auto/Sample/Sample.bundle Expected in: flat namespace in blib/arch/auto/Sample/Sample.bundle at /opt/local/lib/perl5/5.16.3/darwin-thread-multi-2level/DynaLoader.pm line 194. at - line 0. Compilation failed in require. BEGIN failed--compilation aborted. The Math::Int128 module is properly installed and passed tests. Thanks for any insight, Matt

Are you compiling and linking the file c_api_client/perl_math_int128.c into your module?

Yet that looks like a compilation/linker issue. Anyway I know mostly nothing about OS/X and don't have access to a Mac and there is nothing evident that would allow me to narrow the problem. So, I don't know... let my ask in PerlMonks, somebody may be able to help!

Could you show me your full module including supporting files (i.e. Makefile.PL) and the compilation log?

Okay I think I'm getting somewhere. When I run the strings command on the perl_math_int128.o file, the only string that appears is: "Unable to load Math::Int128 C API: your compiler does not support 128bit integers". So the following conditional is failing in perl_math_int128.c: #if ((LONGSIZE >= 8) && (__GNUC__ > 4 || (__GNUC__ == 4 && __GNUC_MINOR__ Show quoted text

>= 4)))

What I can't understand is why Math::Int128 builds and tests successfully...it uses the same stanza, right? Thanks, Matt On Thu, Mar 5, 2015 at 4:12 PM, Matt Sisk <sisk@mojotoad.com> wrote: Show quoted text

Actually, Math::Int128 no longer uses that sort of detection. Instead, it probes the compiler uses feature tests with Config::AutoConf. I'm not sure how to best replicate this with the embedding .c file, since you can't do feature detection in CPP. I was thinking that we could provide a Config::AutoConf recipe for others to use to generate appropriate defines and then fall back to the compiler detection that it does currently.

In any case, I have removed the obsolete compiler checks that were embedded in the C API client files. Matt, could you check with the new versions bundled in v0.21? https://metacpan.org/source/SALVA/Math-Int128-0.21/c_api_client
