Hints for building rpm packages:
Check giac.specs and giac.specs32
NB 32 bits: export CXXFLAGS='-m32 -I/usr32/include'
            export CFLAGS='-m32 -I/usr32/include'
            export LDFLAGS='-L/usr32/lib -lX11'
	    
preparation:
  rpmbuild -bp --short-circuit giac.specs
compilation:
  rpmbuild -bc --short-circuit giac.specs
installation:
  rpmbuild -bi --short-circuit giac.specs
make package
  rpmbuild -bb --short-circuit giac.specs

make all:
  rpmbuild -ba giac.specs
