Comment(by GeorgSWeber):
As contained in Sage-4.1.rc0, singular-3-1-0-4-20090703.spkg does not even
build on OS X, neither 10.4 nor 10.5. Changing the line 201 in
/src/factory/GNUmakefile.in:
{{{
factoryobj := $(factorysrc:%.cc=%.o) $(factorysrc:%.y=%.o)
}}}
into the following two lines:
{{{
factoryobj := $(factorysrc:%.cc=%.o)
factoryobj := $(factoryobj:%.y=%.o)
}}}
made the resulting Singular spkg build on OS X 10.4. But after installing
it into Sage-4.1.rc0, Sage doesn't even start, it fails with:
{{{
ImportError: dlopen(/Users/Shared/sage/sage-4.1.rc0/local/lib/python2.6
/site-packages/sage/rings/polynomial/multi_polynomial_libsingular.so, 2):
Symbol not found: ___eprintf
Referenced from:
/Users/Shared/sage/sage-4.1.rc0/local/lib//libsingular.dylib
Expected in: dynamic lookup
}}}
This might be due to the fact that I had dropped in the 3.1.0.2 Singular
spkg before, so I am re-running the build from the start. (I doubt that
it'll help, but let's see.)
For the record, skipping through the install logs, I spotted another error
(this time "copy'n'paste") in the Singular 3.1.0.4 build scripts. In
/src/libfac/Makefile.in, the two identical lines 157/158 read:
{{{
-$(RANLIB) ${libdir}/libsingfac_g.a
-$(RANLIB) ${libdir}/libsingfac_g.a
}}}
and it is obvious from the surrounding lines, that the line 158 should end
with "..._p.a" instead of "..._g.a".
@Martin:
Would you please report the findings so far upstream?
