I did a bit research on the topic, and the code introduced is circa 100 lines, including docs and esetuppy() which would be probably added anyway. There are other potential problems however. The main issue is how distutils is designed. The only command accepting build-dir is the 'build' command. Other commands which need to access the build tree just use some weird method of getting parameters for other commands. Effectively, if you need to provide a build-dir, you always have to run 'build'. So, the install command would grow from: ./setup.py install ... to: ./setup.py build -b ... install ... Of course, all other commands accessing the build-dir would need to be prepended with the 'build -b ...' as well. For that reason, the patches I'm going to attach add that thing to esetuppy() directly. This has the following implications: 1) all calls to esetuppy() involve running build, 2) if build takes additional arguments, they may need to be passed consistently to all esetuppy calls (like: 'build --foo' in args). Otherwise, a rebuild with different options may happen (but that's probably a case already anyway). In any case, I wouldn't say it's very elegant of Python. It will work flawlessly for the most of Python packages, and likely most of the remaining ones would require running in-source builds anyway (and that can be enabled with a single variable). Well, best just look at the code and tell me what you think. --=20 Best regards, Micha=C5=82 G=C3=B3rny --Sig_/k_b9mUUFr=VAWcN0c9Ujem+ Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iJwEAQEIAAYFAlCNVWkACgkQfXuS5UK5QB2CYgP/Y7ty8obKt5p/PIRkZpT/pndq rOFW3x8A34jTybJuAsBR6s1kdRpnc74VfNsrrupK2dd7SES7XUI5hzUSxYZ8U+Nr kT0zp3NbAbJKpML7iN3eQgtTULp73nIpiIfEg1LgDsv8jiCJ2eMUsLOj1EyOf5Dg sAuXEUltA2Q8agvPBGo= =fPGS -----END PGP SIGNATURE----- --Sig_/k_b9mUUFr=VAWcN0c9Ujem+--
