I am having issues compiling libpng and receiving this error upon make check:

Hi isuclim13,

It looks like libtool is stripping off the “-Wl,” before passing “–version-script=libpng.vers” to pgcc. The “-Wl” flag tells the compiler to pass this the flag to the linker. Since “-Wl” gets removed, the compiler doesn’t know what to do with the flag.

The quick solution would be to add the PGI flag “-noswitcherror” so the compiler simply ignores the unknown flag. However, this may cause other issues depending upon how necessary the version script is.

Otherwise, you’ll need to contact libtool or the libpng folks. I did see a similar error with OpenMPI which was solved by updating the version of libtool used, but I don’t know if this would solve your issue.

Hi mkcolg,

Thanks for the reply. This fix appears to have worked as it compiled and everything looks in place. Make check failed when running (core dumped) but this appears to be a bug inherent to the version of libpng I am using. Thanks again for your help.
