Bug 76637

User-Agent: Mozilla/4.76 [en] (X11; U; SunOS 5.5.1 sun4u)

Description of problem:
We want to build the GD module of perl 5.8.0 using the static version
of libpng i.e. libpng.a . Note: using the shared library everything is
fine. More in detail: when linking with the line
gcc  -shared GD.o  -o blib/arch/auto/GD/GD.so   -lgd -lpng -lz -lfreetype -ljpeg
-lm
everything is ok, but with this line:
gcc  -shared GD.o  -o blib/arch/auto/GD/GD.so   -lgd /usr/lib/libpng.a -lz
-lfreetype -ljpeg -lm
and running make test we get the following error messages:
prompt# make test
PERL_DL_NONLAZY=1 /var/mnt/opt/perl_5.8.0/bin/perl "-MExtUtils::Command::MM"
"-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t

All this applies to the RPM update libpng-1.0.14-0.7x.3.i386.rpm
and libpng-devel-1.0.14-0.7x.3.i386.rpm
The original packages on Redhat-7.2 and RedHat-7.3 did work (!).
To fix this i simply downloaded the source RPMs and rebuilt. The
resulting package worked like expected, so it's probably simply
a build error.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Download the GD module of perl 5.8.0
2. run make
3. run the command listed in the description to use the static libpng.a
4. run make test
	

Actual Results:  error message see Description


Expected Results:  Correct result is the following output:
prompt# make test
PERL_DL_NONLAZY=1 /var/mnt/opt/perl_5.8.0/bin/perl "-MExtUtils::Command::MM"
"-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t

NOTE: it is ok, that test 8 fails, but the important thing is, that
the test runs at all
