Package: petsc
Version: 2.2.0
I followed the instructions in the file README.Debian.gz found in the
package below:
---
[/var/cache/apt/archives] > dpkg -c petsc2.2.0-doc_2.2.0-3_all.deb |
grep README.Debian.gz
-rw-r--r-- root/root 3200 2004-08-12 01:49:06
./usr/share/doc/petsc2.2.0-doc/README.Debian.gz
---
to compile the petsc library for the complex case. In particular, I did:
apt-get source petsc
cd petsc-2.2.0
fakeroot debian/rules PETSC_BOPT_EXTRA=_complex binary
I got an error like this:
---

The problem, in my opinion, is due to the lines 137 and 139 in the file
axpy.h, where functions and variable declarations for "double"s are used
instead of the ones for "complex"s. See the following diff.
---
$> diff axpy_broken.h axpy.h
137c137
< daxpy_(&n,&a1,p1,&one,U,&one);}
---
> BLaxpy_(&n,&a1,p1,&one,U,&one);}
139c139
< double fone=1.0,aa[2];\
---
> PetscScalar fone=1.0,aa[2];\
---
Applying this patch fixed the problem.
No errors were found compiling the PETSC_BOPT_EXTRA=_single and
PETSC_BOPT_EXTRA=_matsingle cases.
