| Subject: | 'libgd' installed in dir with upper case letters |
At work, running under Linux, we have 'libgd' installed in a directory which contain upper case letters. When installing with CPAN.pm I usually enter the location at the prompt.
However in Makefile.PL the input for 'lib_gd_path' is lowercased by 'lc'.
Under Linux this breaks compilation.
I think that the 'lc' is just a type, left over from lowercasing 'Y' to 'y'.
As removing the 'lc' might break existing scripts, I have added a check,
and lowercase only when 'lib_gd_path' does not exist.
A patched 'Makefile.PL' is attached.
use ExtUtils::MakeMaker qw(prompt WriteMakefile);
unless (@ARGV) {
warn <<'END_WARN';
NOTICE: This module requires libgd 2.0.12 or higher.
it will NOT work with earlier versions.
See www.cpan.org for versions of GD that are compatible
with earlier versions of libgd.
Type perl Makefile.PL -h for command-line option summary

Configure GD module.
Options:
-options "JPEG,FT,XPM" feature options, separated by commas
-lib_gd_path path path to libgd
-lib_ft_path path path to Freetype library
-lib_png_path path path to libpng
-lib_zlib_path path path to libpng
If no options are passed on the command line. The program will
prompt for these values interactively.

do not bother Lincoln Stein but get in touch with

Define lib_root as a concealed logical pointing to the
top directory where you have your libraries installed.
E.g. define/job/trans=conc lib_root public$device:[public.util.libs.]\n";
Also define the logical pubbin to point to the location
of the object libraries
Then re-invoke Makefile.PL
Exiting now...
