I have a problem on building fenics 1.5 with hashdist on a outdated rhel5
cluster.
I use gcc-4.8.2 compilers and openmpi 1.7.4.
At the building of ffc using hashdist package I obtain an error related to the
absence of c++11 flags at compile time. This is obtained both with a standard
fenics-install script and with hit build and a personalised profile.
To bypass the issue I created a bogus hashdist package c++11 having the
following content:
when_build_dependency:
- {set: 'CFLAGS', value: '-std=c++11'}
- {set: 'CMAKE_CXX_FLAGS', value: '-std=c++11’}
and set it as a dependence of ffc hashdist package at build and run time. With
this workaround ffc compiles correctly, but when running poisson-demo I get an
error when ffc compile the form related to the absence of c++11 flags, with
error messages in the instant compile.log as the one below. The problem is
really only applying the good -std=c++11 flags at compiling time with instant,
because if I compile manually using cmake with appropriate option to set this
flag, the ffc_form it compiles correctly.
Any suggestion? When and how the instant compiling flags are defined? How can
one modify them?
