error: command 'gcc' failed with exit status 1

[welbeckzhou]

When Compile c++ files to .so for python use:

python setup.py build_ext -i
the error occurs.

I use python 3.6, and the default gcc version in my anaconda env is 7.3.0

mesh_core.cpp:349:31: error: no matching function for call to ‘std::basic_ofstream::basic_ofstream(std::__cxx11::string&)’

I solved this by modified mesh_core.cpp (line 349)
from

    ofstream obj_file(filename);

to

    ofstream obj_file(filename.c_str());

[gangeqian]

this bug always exits in project,
I also solved this issue by modifiing
ofstream obj_file(filename.c_str());
