Not with C example. It says: >> C/C++ example src/snes/examples/tutorials/ex19 run successfully with 1 MPI process <<< However you are probably refering to the message 'Error detected during compile or link!'.

It doesn't mention fortran - and: >>>>>>>>>>> Non-hardening Hardening Compile for dynamic linking -fPIC -fPIC <<<<<<<<<< We already use -fPIC - so it shouldn't have made any difference - so a gfortran bug on i386? <skip logs - will check them > > On Fedora builds, i see this warning without any other info: > > *******************Error detected during compile or link!******************* > See http://www.mcs.anl.gov/petsc/documentation/faq.html > /builddir/build/BUILD/petsc-3.7.4/buildopenmpi_dir/src/snes/examples/tutorials > ex19 > ********************************************************************************* This is just a false positive with the string check with 'error' in '-Werror=format-security'. The C example did run fine.. To fix this - you can use the following patch. https://bitbucket.org/petsc/petsc/commits/69cca02db8de80df74bb113429c95518e4fd7281 Satish
