[Plplot-general] building plplot 5.3.1 on slackware 9.1

[Bryan P. <pet...@ma...>]

When I was building plplot 5.3.1 on slackware 9.1 it failed to recognize
the presence of jpeg or png support in libgd (installed separately - not
part of the distribution).  The problem was that the LDFLAGS was set to
blank before checking and the test failed looking for "pow" that was
referenced by both libpng and libjpeg.  Apparently slackware differs from
the others by not having libm in the default link list and you have to
explicitly include -lm when making this test.
