Gerrit --
Thanks for taking the time to look at the Graphics::MNG module.
There are several issues in your test results. Let's see if I can
address them:
1. Some filenames have been changed to lower-case. I've traced this to
my Win32 port of the 'tar' utility. The files are named correctly on
my hard drive, but are lower-case in the 'tar.gz' file. They appear
correctly in the 'zip' file.
This would cause problems for (at least) the following files:
Makefile.PL => makefile.pl
MNG.pm => mng.pm
Lcms.h => lcms.h
I'll see if I can re-package this with the correct filenames and
upload it again.
2. As indicated in the README (er, readme) file, I've only tested on
Win32. On top of that (as indicated in the Makefile.PL (er,
makefile.pl)), I've been unsuccessful in coming up with a 'lib' file
that will allow me to properly link/load the published libmng.dll.
I've included a static library build of the libmng for Win32 for these
reasons:
1. Convenience -- everything you need to build for Win32 is in the
package. You don't have to go download libmng (although this
would be better if I could link against the DLL).
2. Build issues -- since the package is still sensitive to
compilation flags, I wanted to provide a compatible libmng library
for the Perl I/F.
3. The end user is not obligated to use the default settings in the
Makefile.PL. I've provided verbose comments suggesting that the
user should edit the Makefile.PL as appropriate for include and
library paths. I've even mentioned this in the README file.
3. Since I haven't built on cygwin, I don't know why you wouldn't be able
to link against the library. Perhaps I have some compilation flags
set wrong for cygwin? If I can find the time, I'll install cygwin and
try to build Graphics::MNG there. If different compilation flags are
necessary, I can easily accomodate alternate sets of parameters in the
Makefile.PL file based on the operating system type.
Testing on any UNIX-like platforms is likely to yield the same
results. You may want to limit your testing to the Win32 platform for
now.
Sorry you didn't get it to work.
Thanks for trying.
