Dear pythoneers, I am using distutils for a scientific plotting package for python. Recently I added the configuration part of the installation process to setup.py (previously, it was done with a 'make config'). My setup.py now looks like ... from distutils.command.config import config ... class my_config (config): def run (self): self.configthis() self.configthat() ... def configthis(self): ... def configthat(self): ... ... setup( ... cmdclass = {'config': my_config}, ... ) This all works, except for a few glitches (running Python 2.2.2): 1) On Cygwin, 'python setup.py config' tries to run the cc compiler, instead of the gcc compiler. By adding --compiler=cygwin, I can force it to use the gcc compiler and everything works, but this should not be necessary. When executing 'python setup.py build', I don't need to specify --compiler=cygwin, distutils chooses gcc automatically. 2) On Linux, I get an error message from distutils/command/config.py line 155: prog = prog + self.compiler.exe_extension TypeError: cannot concatenate 'str' and 'NoneType' objects The problem here is that on Linux, self.compiler.exe_extension is None, and python does not allow None to be concatenated with a string. If self.compiler.exe_extension would be "", it would work. 3) Running 'python setup.py config' produces a lot of output, such that a user would probably miss an error or warning message. Is there a way to reduce the amount of output by default? Such that a user who simple-mindedly runs 'python setup.py config' sees the important information only? Any help will be appreciated. I apologize if these are known issues. --Michiel. -- Michiel de Hoon, Assistant Professor University of Tokyo, Institute of Medical Science Human Genome Center 4-6-1 Shirokane-dai, Minato-ku Tokyo 108-8639 Japan http://bonsai.ims.u-tokyo.ac.jp/~mdehoon
