--compiler build option on windows

[vbabiy]

On Windows while installing from source code several packages (psycopg2, PIL, ...) emit an error:

error: Unable to find vcvarsall.bat

The issue is being fixed by installing MinGW and using mingw32 compiler like this:

setup.py install build --compiler=mingw32

As far as I see, it would be very good for PIP to have "--build-option" like "--install-option", so that one could use PIP with mingw32 compiler:

pip install --build-option="--compiler=mingw32" psycopg2

I could solve the problem adding:

[build]

compiler=mingw32

to the file distutils.cfg in C:\Python27\Lib\distutils\

I would also like to see pip support a --build-option for the same reason. I
recently ran into the issue when using pip to install MarkupSafe and ended up
using a %USERPROFILE%\pydistutils.cfg file with the same content as the OP.

I wonder does '--install-option' meet your requirements? I have not tried it,
but it looks like it will work. Note, it's "hidden" in the help output of the
install command.

# pip install --help

....


--install-option=INSTALL_OPTIONS

                        Extra arguments to be supplied to the setup.py

install

                        command (use like --install-option="--install-

                        scripts=/usr/local/bin").  Use multiple --install-

                        option options to pass multiple options to

setup.py

                        install.  If you are using an option with a

directory

                        path, be sure to use absolute path.

Using --install-option in the following manner doesn't currently work. I still
need to do something like http://jonforums.github.com/python.html as a
workaround.

C:\tools>pip --version pip 0.8.2 from c:\python27\lib\site-
packages\pip-0.8.2-py2.7.egg (python 2.7)

C:\tools>pip install --install-option="--compiler=mingw32" markupsafe
Downloading/unpacking markupsafe Running setup.py egg_info for package
markupsafe

Installing collected packages: markupsafe Running setup.py install for
markupsafe usage: -c [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...] or:
-c --help [cmd1 cmd2 ...] or: -c --help-commands or: -c cmd --help

error: option --compiler not recognized

Thanks vbabiy for the workaround. I too would like to see this option.

Need some easy-to-use command-line way to install mercurial via pip on windows. Since Microsoft (c) (r) (tm) removed compiler from Windows 8 (c) (r) (tm) SDK, it's more important now.

Could somebody from core devs please comment on what's needed to move this forward? Is addition of --build-option option and passing its value to setup.py build the way to go?

pip doesn't currently call setup.py build directly to be able to pass the options.
more likely in the short term I think that we add build option support to "pip wheel", which is due out in pip-1.4?
not sure, see #881, @dholth , @pfmoore ?

[dholth]

Do you need to give the same options to every build? Can we ask you to do it manually for those non-default builds?

Bdist_wheel certainly may not be sophisticated enough to pass the arguments anyway......

what are you suggesting? how manually?

I guess somebody can do this?

pip install --no-install SomePackage
cd <venv>/build/SomePackage
python setup.py build --compiler=special-compiler
pip install --no-download SomePackage
