Re: Cross-build failure from Linux

Hello,

I'm trying to cross-build NetBSD/macppc from a Debian testing
installation on a PowerMac G5 (ppc64). In doing so, I hit the error
below during the build of gcc as part of "build.sh tools":

Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.

Any ideas?

In fact, I haven't been able to crossbuild NetBSD from non-NetBSD
hosts for a while, and I think I tried various variants of Linux and
FreeBSD... although I can't remember if I tried elsewhere than on this
G5.

Thanks,

Hi,

i build my NetBSD macppc for PowerMac G5 on Arch Linux amd64
without any problems. And i built it on NetBSD macppc G5 itself
successfully too but i never tried to build it on FreeBSD G5 or Linux G5.

Regards
