Subject: [PATCH] libpng probe/test fails with non-standard location
Date: Wed, 18 Aug 2010 18:00:45 -0700
To: bug-Imager [...] rt.cpan.org
From: Justin Davis <jrcd83 [...] gmail.com>
I have installed libraries and modules into a separate prefix for a website I am developing. When I try to install Imager using a libpng that is in a non-standard location (directory) Makefile.PL fails to probe libpng and returns an error. I also noticed pkg-config could not find png's information. This is because pkg-config's data-files are also in the non-standard location, in the $PREFIX/lib/pkgconfig/ directory. I will paste the example problem output and attach a patch for lib/Imager/Probe.pm, which PNG/Makefile.PL uses. EXAMPLE OUTPUT (BEFORE PATCH) [juster@artemis Imager]$ perl Makefile.PL --incpath $PREFIX/include --libpath $PREFIX/lib done. gif: includes found - libraries found ungif: includes found - libraries not found jpeg: includes found - libraries found tiff: includes found - libraries found freetype2: includes not found - libraries not found freetype2: not available T1-fonts: includes not found - libraries not found TT-fonts: includes not found - libraries not found w32: includes not found - libraries not found EXIF support enabled Checking if your kit is complete...

There was a typo in Imager::Probe which never allowed LD_RUN_PATH to be set. I have also allowed pkg-config to search non-standard locations by setting the PKG_CONFIG_PATH environment variable. Thanks, Justin

Hi, This is fixed in Imager 0.78, thanks for the report. Tony
