* status: needs_review => needs_work
Comment:
The SConstruct file doesn't work. First make a symbolic link "gplusplus"
to "g++". Then:
{{{
jdemeyer@arcanis:/usr/local/src/sage-5.0.beta1$ gplusplus --version
gplusplus (GCC) 4.6.3 20120123 (prerelease)

jdemeyer@arcanis:/usr/local/src/sage-5.0.beta1$ CXX="gplusplus" ./sage -b

sage: Building and installing modified Sage library files.
Installing c_lib
AttributeError: SConsEnvironment instance has no attribute
'SharedLibrary':
File "/usr/local/src/sage-5.0.beta1/devel/sage-main/c_lib/SConstruct",
line 138:
lib = env.SharedLibrary( "csage", [ "src/" + x for x in srcFiles ],
ERROR: There was an error building c_lib.
}}}
So, I think
{{{
# the following two lines should probably be replaced with a better test
}}}
should actually be done. You should check features, not names of
executables.
