DynaLoader isn't finding libm.a

princepawn has asked for the wisdom of the Perl Monks concerning the following question:

I am attempting to use a module which was built via SWIG and I get the following error:

Can't load '/home/tmbranno/cpan/lib/perl5/site_perl/5.005/sun4-solaris
+/auto/gdc\
hart/gdchart.so' for module gdchart: ld.so.1: /usr/local/bin/perl: fat
+al: reloc\
ation error: file /home/tmbranno/cpan/lib/perl5/site_perl/5.005/sun4-s
+olaris/au\
to/gdchart/gdchart.so: symbol ceil: referenced symbol not found at /us
+r/local/l\
ib/perl5/5.00503/sun4-solaris/DynaLoader.pm line 169.

I even tried to force Dynloader to open the math library (as that's where ceil() is defined), but it won't find the symbol for ceil for some reason:

#!/usr/local/bin/perl -I/home/tmbranno/cpan/lib/perl5/site_perl/5.005

use DynaLoader;
BEGIN { dl_load_file("/usr/lib/libm.so");
use gdchart;

The "ldd" command ("list dynamic dependencies") is often very useful in debugging such problems. If you find that you need to set LD_LIBRARY_PATH at run time to get things to work then you may want to specify LD_RUN_PATH at compile/load time instead. But these things vary between operating systems, of course. - tye (but my friends call me "Tye")	[reply]

Check `$ENV{LD_LIBRARY_PATH}`. I think that's usually the problem with dll loading on Solaris. After Compline, Zaxo	[reply] [d/l]
