Dear All,
I have been trying to install Code Aster on a powerpc on which I only have user permissions.
The admin confirmed that

gcc.ppc64 v4.4.6-4.e16
gcc-c++.ppc64 (gcc c++ support)
gcc-gfortran.ppc64 (gcc fortran support)
python.ppc64 v2.6.6-29.e16_2.2
python-devel.ppc64 v2.6.6-29.e16_2.2
numpy.ppc64 v1.4.1-9.e16
PyQt4.ppc64 v4.6.2-8.e16
tk.ppc64 v1:8.5.7-5.e16
bison.ppc64 v2.4.1-5.e16
flex.ppc64 v2.5.35-8.e16
lapack.ppc64 v3.2.1-4.e16
blas.ppc64 v3.2.1-4.e16
zlib.ppc64 v1.2.3-27.e16

are installed but I cannot sort out some lapack related errors like:

---------- ERROR MESSAGE ----------

lapack and lablas are in /usr/lib64, I linked them to another folder as shown here

[pschmitt@localhost aster-full-src-10.7.0]$ ls -rtl liblinks
total 0
lrwxrwxrwx. 1 pschmitt pschmitt 29 Jul 5 12:43 liblapack.so -> /usr/lib64/liblapack.so.3.2.1
lrwxrwxrwx. 1 pschmitt pschmitt 27 Jul 6 12:05 libblas.so -> /usr/lib64/libblas.so.3.2.1

and then use

MATHLIB = '-L/home/pschmitt/aster-full-src-10.7.0/liblinks -llapack -L/home/pschmitt/aster-full-src-10.7.0/liblinks -lblas'

to specify the directory but with no success.

Thanks for any ideas on how to fix this,
Pal

Hello Wavemaster,

I get a similar error (approximately) when I use the install script and point to the threaded Intel maths libraries instead of the default sequential ones (Ubuntu 12.04). When the script asks whether I want to proceed despite the error I enter "yes" and the compilation continues successfully.

I'm not sure if this is any help...

Hi,

I had a look at the setup.log files you submitted and it seems to me everything went OK although there's an error about BLAS/Lapack at the configure stage.

Indeed everything installed OK except :

- grace but this is because you're missing the motif library. Moreover grace is optional (it is used to plot some graphs).

- homard : this is a mesh refinement software. The aster package contains an x86 binary which therefore will not work for ppc64. It is also optional so no worries.

Now you should try to go to the install location and try to launch a simple test :

Code:

$  cd /home/pschmitt/aster/testing
$ /home/pschmitt/aster/bin/as_run forma01a.export (or any export in this directory)

This will launch a simple test. If the diagnostic is OK then your install works.

However in your case it should fail. This is expected. Indeed Aster makes some internal assumptions, one of which is that we're running a little endian processor. Since PowerPC is big endian, you'll need to fix one function in the source code.
This is explained here : http://www.code-aster.org/forum2/viewto … 731#p11731

After fixing envima.c, you need to rebuild the Code_Aster binary :

Code:

$ /home/pschmitt/aster/bin/as_run --make

TdS

Dear All,
Thanks you very much for your comments.
When i run the forma1.export test case I still get errors, which is different from the one in the post

http://www.code-aster.org/forum2/post.p … ;qid=11714

. I will try to apply the patch and update you on how it goes...
Cheers.
