Re: [Fwd: Portable version]

[Domingo Alvarez Duarte]

Hello Benhard !

Probably the easy way is to static build/link glpsol.

I normally look at the end of the make output and manually replace it:

====

examples$ make
gcc -DHAVE_CONFIG_H -I. -I..  -I./../src   -g -O3 -march=native -ffp-contract=off -DWITH_SPLAYTREE -flto -MT glpsol.o -MD -MP -MF .deps/glpsol.Tpo -c -o glpsol.o glpsol.c
mv -f .deps/glpsol.Tpo .deps/glpsol.Po
/bin/bash ../libtool --tag=CC   --mode=link gcc  -g -O3 -march=native -ffp-contract=off -DWITH_SPLAYTREE -flto   -o glpsol glpsol.o ../src/libglpk.la -lm
libtool: link: gcc -g -O3 -march=native -ffp-contract=off -DWITH_SPLAYTREE -flto -o .libs/glpsol glpsol.o  ../src/.libs/libglpk.so -lm

====

Rerun the glpsol link as (replace the ouput "-o" and the libglpk from shared to static):

====

gcc -g -O3 -march=native -ffp-contract=off -DWITH_SPLAYTREE -flto -o glpsol glpsol.o  ../src/.libs/libglpk.a -lm

====

Cheers !

Hi,

I'm currently working for the Chair of Symbolic Computation in Passau
and help developing ApCoCoA-2, a computer algebra framework mainly for
commutative algebra for Linux and for Windows.

We would like to include include a version of GLPK into our framework,
but have failed yet with compiling a portable standalone version of
glpsol as the configuration and the built always writes direkt paths
into many files. Also replacing all paths by new ones didn't help.

Is there a way to compile a portable version?

Best Regards
Bernhard Andraschko

Dear Bernhard,

please, provide a log of the errors that you observed.

On Linux you may have to set LD_LIBRARYY_PATH if you put GLPK library into an unusual place.

Don't forget running ldconfig.

On Windows the GLPK library must be in one of the directories indicated by %PATH%.

Best regards

Heinrich
