Re: [vsipl++] Compiling VSIPL++ on Cell PPE

[Hahn Kim <hgk@xxxxxxxxxx>]

Thanks for the feedback, configure now completes without error, but  
now I'm encountering problems with make.
When I add --with-lapack=no, configure completes:

> ./configure --prefix=<dir-containing-vsipl++>/sourceryvsipl++-1.3- 
mpich2-1.0.6-sal --with-mpi-prefix=<dir-containing-mpich2>/ 
mpich2-1.0.6 CXXFLAGS="-O2 -DMPICH_IGNORE_CXX_SEEK" --with-sal- 
include=/opt/MultiCorePlus/include --with-sal-lib=/opt/MultiCorePlus/ 
lib --enable-fft=sal --disable-builtin-atlas --with-lapack=no

When I run make, I get the following error:

If I disable everything, then VSIPL++ builds to completion and I'm  
able to build and run example1:
./configure --prefix=/data/PVTOL/vendor/ppc64/Linux-2.6.22-0.ydl.rc4/ 
sourceryvsipl++-1.3-mpich2-1.0.6-nolapack --with-mpi-prefix=/data/ 
PVTOL/vendor/ppc64/Linux-2.6.22-0.ydl.rc4/mpich2-1.0.6 CXXFLAGS="-O2 - 
DMPICH_IGNORE_CXX_SEEK" --disable-builtin-atlas --with-lapack=no

This is good for now, it will let us use VSIPL++ in a functional  
manner.  Later, it would be nice to be able to compile an optimized  
version linked to SAL.  Any help is appreciated.
