The culprit seem to be that shutil.copyfile() isn't working on my vagrant
config.
In emcc:
elif file_ending.endswith(DYNAMICLIB_ENDINGS) or
shared.Building.is_ar(input_file):
logging.debug('copying library file: ' + input_file)
temp_file = in_temp(uniquename(input_file))
shutil.copyfile(input_file, temp_file)
sys.exit("BLLLLLLAAAAAAAA: from: " + input_file + " to: " +
temp_file);
temp_files.append(temp_file)
the "sys.exit" is mine for debugging. After that statement exits, there is
nothing in /tmp. The output is as follows:
BLLLLLLAAAAAAAA: from: foundation/libfoundation.a to:
/tmp/tmpYXfs1H/libfoundation_7.a
I'll look deeper into the problem now. My config is:
Host: OSX 10.9.1
VM: Ubuntu Precise 64-bit
emscripten and all required tools are installed in the VM, but my project
directory is shared with the host filesystem.
