Here's another random question from me, for all of the experts on the list ;-)
This one is related to Makefile.am configure.ac - autotools.
I've produced a stage1 cross compiler. I do not yet have a full libc -
just headers - crt files do not exist, so I can't create an
executable. But I would like to compile my libc, and I've decided to
use autotools for some crazy reason. This is a small C library that
I've written (including all the necessary crt files) so the problem
isn't specific to glibc, although I do recall having run into this one
before.
The only problem with autotools and using a stage1 compiler, is that
the macro AC_PROG_CC in configure.ac always dies because the compiler
tries to link main to a fully-fledged executable can't find the crt
files yet.
Is there some kind of auto-magical autoconf incantation that only
checks to see if the compiler can simply compile (and not necessarily
link)?
For some reason, AC_<blank>_<blank>_CHECK comes to mind, but I could
just be senile.
PS: the only justification I have for inquiring on #gentoo-embedded is
because I'm building my package with emerge and it happens to be for a
cross-toolchain built with crossdev :)
