I made suggested changes, and everything compiles/installs/runs. What I
did was change acinclude.m4 in the sgi section to:
if test $ac_cv_prog_gcc = "yes" ; then
DX_RTL_CFLAGS=" -D_GNU_SOURCE -Dsgi"
DX_RTL_LDFLAGS=" -shared"
DX_RTL_DXENTRY=" -e DXEntry -exported_symbol DXEntry"
I did not change DX_RTL_DXENTRY to " -eDXEntry".
For the dx builder generated makefile to work, I needed to make a couple
of changes:
compiler from cc to gcc
add CCLD = ld
add SYSLIBS = -lm -lc
AND MOVE the $(DX_RTL_LDFLAGS) from 2nd to last to follow $(LDFLAGS) under
the #create the necessary executable. Otherwise I was getting:
ld32: ERROR 4: Conflicting flag setting: -shared
I was expecting to see DX_RTL_DXENTRY in the generated makefile, so now I
notice that I no longer need the "-e DXEntry -U -exported_symbol DXEntry"
for my older makefiles. Correct?
