Hello again,

By default, NDEBUG should be defined (otherwise uBLAS becomes useless
even for very small problems). That is,

# Default CXX and FORTRAN flags
env["CXXFLAGS"] = "-Wall -pipe -ansi -DNDEBUG"
This is probably not the best place to add this flag. It is perhaps
better
to add it when enableOptimize=1 is given. For now, you can use the
option
customCxxFlags to add the -DNDEBUG flag, i.e.

    scons customCxxFlags="-DNDEBUG"

Well, I still don't think it makes sense to relate -DNDEBUG with
enableOptimize. One should use enableDebugUblas if NDEBUG is _not_
wanted. In my SConstruct I have

if not env["enableDebugUblas"]:
   env.Append(CXXFLAGS=" -DNDEBUG")

Yes, I agree with you on that. Fixed it now.

Thanks!


Another concern: Did it find UMFPACK or not when it says:
Checking for numpy-1... yes
Checking for ufc-1... yes
Checking for umfpack... yes
Checking for python-2... yes
Checking for gts... yes
Checking for boost... yes
Checking for libxml-2.0... yes
Found optional package: gts
Unable to find optional package: petsc
Unable to find optional package: slepc
Unable to find optional package: scotch
Unable to find optional package: umfpack
Well, it did find a pkg-config file for UMFPACK, however, it failed when
resolving compiler or module dependencies. What does your umfpack.pc
look
like? Does it specify a compiler? That could probably be the issue here.

(I get some 'new' linking issues when building the demos: cannot find
libumfpack)
Can you show us the contents of scons/simula_scons.log?

Okay, it doesn't find the umfpack.h under /usr/include/umfpack. Do you now
where it is located? Can you also show me the contents of the pkg-config
file umfpack.pc?
