It is possible to support cross compilation with autoconf-based build
systems. configure supports this by use of cache variables; standard
practice is to build up a config.site file with the correct test
results for the target (e.g. ac_cv_func_setpgrp_void=yes), and set
CONFIG_SITE to point at that file. More work may be needed on the
configure scripts to use AC_CACHE_CHECK appropriately.
Ah, do I have to patch anything for that or does it run out of the box ?
I had exactly the same problem with openssl. I fixed it by simply
pulling off several checks (ie the file-exist-checks simply refused
to work in crosscompile mode) and recreated configure. The tests I
removed were meaningless for my platforms nevertheless.
But the problem is another point: autoconf is not really made for
crosscompiling. the support for different tool commands and the so called
crosscompile support (simply disable a bunch of checks or refuse to
work when it doesnt know what to do now) is just an ugly hack, neither
are sysroot builds supported in any way.
To get a really reliable solution for that, we need an new, well designed
universal toolchain frontend. this of course could also be shipped with
apache for a while (- vendor branch ... grrmpf).
But the Makefiles still won't work since they have no separate of host
and target $CC etc, yet need to build and run executables on the host
system in several places. So there is definitely more work needed
there.
Right.
I'm passing my crosstoolchain commands (CC,LD, ...). But this only
works as long as the package doesnt bring its own host-side-tools.
We need at least an *clear* distinction between host und and target
compilation.
These are all questions for the unitool, which I already announced
here. For those who dont remember:
