Bug #70279 for GD: bug in GD: library path options are discarded

Dear Sirs, Although the documentation states that paths to libjpeg, libpng et al. can be specified via the config switches 'lib_something_path=...', this was true only until GD 2.35, because from 2.39 on there is a GetOptions("ignore_missing_gd" => \$force); line in the Makefile.PL that discards all commandline arguments unknown to it - that is, everything except the ominous '-ignore_missing_gd'. Currently we are quite fine with 2.35, but if our customers required a newer version, we will have to upgrade to it, and it would be good if it would be possible with a clean build, without manually patching out the offending lines from the Makefile. The situation can be reproduced quite easily: - create an environment with no lib{jpeg,png,gd} in the default search paths - /somewhere/perl Makefile.PL -lib_png_path=/not/necessarily/exists/png If it recognises the option, you will get something like this: $ perl Makefile.PL -lib_png_path=/asdf/png PNG library used from: /asdf/png Where is libgd installed? [/usr/lib] If the options are already discarded, you will see: $ perl Makefile.PL -lib_png_path=/asdf/png Unknown option: lib_png_path **UNRECOVERABLE ERROR** Could not find gdlib-config in the search path. Please install libgd 2.0.28 or higher. If you want to try to compile anyway, please rerun this script with the option --ignore_missing_gd. As the fix is trivial, I hope you can include it in the upcoming releases.
