Source: talloc Version: 2.3.3-2 Tags: patch User: [email protected] Usertags: cross-satisfiability ftcbfs
talloc fails to cross build from source. I'm inclined to say it's because waf. Really, stop using waf if you can. It's a nightmare. Ok ok. It's bad, but not impossible. I've attached this huge patch to make it work. Of course you can apply it and it'll work, yes. But how about stop using waf? Polemics aside. waf can be made to cross build if you export all the build tools. Beyond the usual ones, you also need PYTHON3_CONFIG and this magic _PYTHON_SYSCONFIGDATA_NAME variable. Of course, debian/rules also needs to use it instead of calling python3-config directly. Beyond that, a waf anser file is needed. And that's mostly it. Build-Depends need to be multiarchified and the python3-talloc.lintian-overrides was wrongly hard coding the amd64 triplet. It really can be made to work. But is all this pain really worth it? How about using like setuptools or something sane? Think about it. And if all else fails, apply my patch. Helmut
