Gaby,
Recently when building on Solaris x86 I found that I also needed the
'-lm' option in the Makefile for
src/graph/viewAlone/Makefile
! AXIOM_X11_LDFLAGS = -L/usr/openwin/lib -R/usr/openwin/lib -lm -lXpm
-lSM -lICE
-lX11
and
src/graph/viewman/Makefile
! viewman_LDFLAGS = -lm $(axiom_target_libdir)/libspad.la \
$(axiom_target_libdir)/libopen-axiom-core.$(DLLEXT)
Apparently the change to LDF is not quite sufficient in these two
cases. I still think the autoconf test is the best way to go.
Regards,
Bill Page.
