building GD using a locally-installed libgd (old libgd also present on system)

I'm trying to build GD, but have it use a libgd (Boutell's C library)
that I built in my own ~/opt directory. The problem is, there's also an
older libgd installed on the system (2.0.9 I think), but I don't have
root access and so cannot remove this older version. I want GD to
eventually get installed into ~/perllib.

I've tried "perl Makefile.PL PREFIX=/home/me/perllib", but
unfortunately, it's finding the gd.h in /usr/include (the old one)
instead of /home/me/opt/include (the current one), and it's causing the
build to fail.

How can I get GD to build correctly using my own locally-installed
libgd on a system that also has an older libgd present?

Probably easiest to just do some appropriate harcoding in the Makefile.PL.
(This is what I do on Win32, and it works for me.)

Find the'LIBS' and 'INC' entries in the WriteMakefile() section of said
Makefile.PL and change them to something like:

'LIBS' => [join(' ','/home/me/opt/lib',@LIBPATH,@LIBS)],
'INC' => join(' ','/home/me/opt/include',@INC),

Then just run 'make clean' and start over again - responding to all prompts
as usual.

You haven't told us where libgd is so I've had a guess that it's in
/home/me/opt/lib - which, of course, is not necessarily the case.

Hm. Seems like there ought to be an easier way...

Yup. That's the place.

Well, anyway, after changing those lines in Makefile.PL, creating the
makefile seems to still have issues:

That ./blib/arch/auto/GD/GD.so does indeed exist. Line 14 of GD.t is:
"use GD qw(:DEFAULT GD_CMP_IMAGE);".

After that, "make install" seems to work fine.

For kicks, I tried out the demos anyway. I added "use lib
'/home/me/perllib';" and they wouldn't work. Then I tried "use lib
'/home/me/perllib/lib/perl5/site_perl/5.8.0/i386-linux';", and, to my
surprise, they worked. The sample cgi script also worked.

Why did "make test" fail?

Hm. Also note:

~/opt/src/perl_modules/GD-2.35/blib/arch/auto/GD$ ldd ./GD.so
[snip]
libgd.so.2 => /usr/lib/libgd.so.2 (0x0030a000)
[snip]

So, it's not even using my new libgd.

You're sure that /home/me/opt/include/gd.h exists ? .... it's not (eg)
/home/me/opt/include/gd/gd.h ?

How about:

'LIBS' => [join(' ','-L/home/me/opt/lib',@LIBPATH,@LIBS)],
'INC' => join(' ','-I/home/me/opt/include',@INC),

(Sorry about that ... without the '-L' and '-I' switches those first
elements achieve nothing.)

Turns out that on Win32, all I really need to do is have:

'LIBS' => [join(' ',@LIBPATH,@LIBS)],
'INC' => join(' ',@INC),

And both gd.h and libgd.a are found correctly - so long as I provide the
correct location of libgd.a when prompted by the Makefile.PL. Based on the
reported location of your gd.h and libgd.a, the same should be happening for
you .... don't knowwhy that's not the case. Anyway, try inserting the '-L'
and '-I' (that's uppercase i) and see if that helps. (For me, libgd.a is in
D:/MSYS/local/lib and gd.h is in D:/MSYS/local/include.)

Cheers,
Rob

Yup to the former. That header is where it's supposed to be.

Whoops. That slipped by me too. I made the change, but still get the
same results. (Incidentally, I noticed that, in the resulting makefile,
there's some duplication now, with that path getting mentioned in a
number of places twice in a row).

Hm.

Wait. How is it that you're getting prompted somehow for libgd.a? I'd
be happy to statically link to libgd.a, but don't yet know how. How do
I tell GD's Makefile.PL that I'd like to statically link to libgd? That
would actually solve my problem here pretty nicely. When I built libgd,
I got both the .so and the .a in ~/opt/lib.

BTW, currently, when running "perl Makefile.PL LIB=/home/me/perllib",
I'm not getting prompted for anything, since the new libgd I built has
its own gdlib-config in ~/opt/bin which is evidently being used
correctly by GD's Makefile.PL.

Thanks for all the help! :)

From the Makefile.PL:

my $PREFIX = $lib_gd_path;
if( ! defined($lib_gd_path) )
{
warn "\n";
$PREFIX = prompt('Where is libgd installed?','/usr/lib');
}

But, of course, $lib_gd_path will already have been defined for you by
gdlib-config - which is not being found in my case. I do have gdlib-config,
but my cmd.exe shell wouldn't be able to use it directly - even if it could
find it.

I just keep thinking that there must be some hardcoded 'LIBS' and 'INC'
entry that will do the trick - since that's what gets used to write the
makefile.

I thought that '-lgd' would have the linker link to 'libgd.a' rather than
'libgd.so' - because it would use the first file it finds and it would find
libgd.a before finding libgd.so. (I could be wrong about that, too.)
Is the .a a static library ? ... or is it merely an import library for the
..so ?

In my case, libgd.a *is* a static library - there is *no* shared library.
And I had to therefore take the additional step of altering the 'DEFINES'
entry in the WriteMakefile() section to:

'DEFINES' => $defines . " -DNONDLL"

The same may not apply in non-windows environments. If it *does* apply then
it's unlikely to be '-DNONDLL' - more likely something like '-DNONSO'.

In any case, if the .a is just an import lib for the .so, then you shouldn't
have to worry about any of that.

Yes - and I don't know why is allowing the /usr/include/gd.h to get in the
way. Might pay to run 'gdlib-config --all' and check that it's not throwing
up something you don't want.

Hmmm ... I fear that all I have yet provided is more appropriately
classified as "red herrings" rather than "help" :-)

I've just fired up my linux box. Initially I got warnings, too, about
another gd.h in /usr/include. Renaming it (and gd_io.h) so that they
wouldn't get found fixed that - but didn't make any difference when it came
to building GD. 'make' runs ok, but the perl GD.so cannot be loaded because
of an undefined symbol - different symbol to the one that's tripping you up.
I have only gd-2.0.28, and I'm not confident that's sufficiently recent for
GD-2.35 (despite the claim made by the Makefile.PL).

I don't know why that animated gif symbol is not being resolved for you. If
you don't need animated gif support you could try building GD-2.35 without
it - but that's another kludge you should not have to be bothered with.

Cheers,
Rob

Possibly. Though, I'm now guessing the "right way"(tm) to do it is to
set various variables on the "perl Makefile.PL FOO=bar" command line as
described in the ExtUtils::MakeMaker docs. I've tried various
combinations of those, but have not had any luck. For example, tried:

perl Makefile.PL LIB=/home/me/perllib LINKTYPE=static
INC=/home/me/opt/include LIBS=/home/me/opt/lib/libgd.a

and

perl Makefile.PL LIB=/home/me/perllib LINKTYPE=static
INC=/home/me/opt/include LIBS=/home/me/opt/lib

with no luck.

I think that '-lgd' tell the link editor to try and link in libgd.so
only.

It's a static lib. I think the term "import library" is a
Windows-specific thing, but I'm not familiar with it. On GNU/Linux, we
have static libs (.a) and shared libs (.so).

Dunno. Though, I still feel like MakeMaker should be smarter than this.
That is, I should be able to simply tell it to please link only to the
static lib for libgd... I'll have to research this a bit more. It's
gotta be a pretty commonly-needed thing...

Then thank you for your time. :)

For now, my plan is to dig around and find out how to properly use
MakeMaker so I can tell it to statically link to libgd.
