Not an Gentoo issue. The upstream packages are *broken*. |
| 11 |
|
| 12 |
I'm fighting against those things for several years now. Because |
| 13 |
upstream of many packages isn't quite interested in getting my |
| 14 |
patches in (or too slow), I've founded my own QM project: |

You'll find many patches (ie. for Xorg packages) here: |

Autoconf is dumb. And some people writing autoconf input files |
| 32 |
are even more dumb. Sorry if it sounds offending, but its true. |
| 33 |
|
| 34 |
Although, the autotools collection claims to be suited for |
| 35 |
cross-compiling, it actually isn't. At least not cleanly. |
| 36 |
Clean crosscompiling (aka in an sysroot-environment) does not |
| 37 |
work without deeper changes. So, for example, I had to write |
| 38 |
my own libtool implementation, because the original one is not |
| 39 |
capable of doing sysroot'ed builds. Also many other standard |
| 40 |
macros are broken. The assumption, host root and build root |
| 41 |
already is broken design, as well as the assumption, the |
| 42 |
toolchains for host and target system were equal. |
| 43 |
(ie. that's why mysql can't be crosscompiled: it brings some |
| 44 |
code generator, which is built with the target toolchain, |
| 45 |
and of course this can never work when crosscompiling). |

Fix configure.in. As I did. |
