[petsc-dev] PETSc blame digest (next) 2015-06-16

Tue Jun 16 17:04:48 CDT 2015

Hi Fande,

the respective configure log states that GCC 4.6.3 was used. Have you 
tried to compile using GCC 4.6.x? You might have it available as an 
alternative in your package manager.

Did you check whether the flags
-std=c89 -pedantic -Wno-long-long -Wno-overlength-strings -fPIC -g3 -O0
show up in your build as well?

Best regards,
Karli
