Hi,

I'm trying to build Singular 3-0-2beta under OpenBSD3.9.

I download the gmp sources and make a gmp directory under the /Singular-3-0-2 directory
and make and install gmp and found out that gmp uses this "pentium3-pc-openbsd3.9" when running
gmp configure.

To make configure work better I do like this

./configure --host=pentium3-pc-openbsd3.9 --build=pentium3-pc-openbsd3.9 --target=pentium3-pc-openbsd3.9 --with-malloc=system

Configure runs with no errors.

gmake works after after some manual configuration in NTL Configuration File../ntl/config.h

but ends up in this error:
---log ---

gmake[2]: Leaving directory `/home/eraudag/eraudag/proj/temp/byggen/Singular-3-0-2/ntl'

How to work around this little problem ?

You may try the following trick:
- copy gmp.h to OpenBSD/include/gmp.h
- edit the copy and remove all lines containing __GMP_DECLSPEC_XX
- change IntegerProgramming/si_gmp.h factory/cf_gmp.h kernel/si_gmp.h
to the single line:
#include <gmp.h>
and recompile.
Hope that helps,
Hans Schoenemann, Singular team

It worked! Nice "trick".
Thanks Hans.

ESingular works fine but Singular confuses me with this log
