hi,

i've just tried to crosscompile gentoo and started with this:
Code:
xemerge system

using the emerge wrapper from the embedded gentoo handbook [1].

the package mpfr breaks the build with this error:
Code:

the problem is that mpfr tries to link against /usr/lib/libgmp.so and not against /usr/arm-unknown-linux-gnu/usr/lib/libgmp.so which would be the correct one in my SYSROOT. i couldn't fix the ebuild or the package itself. maybe somebody could give me a pointer on what i could try to make mpfr compile.

thx, simon

Hi Simon,

I know these problems. I usually pause the emerge after configure has finished
(ctrl-z) and have a look at the various Makefiles. Chances are there are some
LDFLAGS which can be corrected. Or, emerge problematic packages on the target
itself.

I do the latter on my SH4 and MIPS systems. You should be able to emerge
a native arm toolchain on your x86 host (it worked for sh4 and mips32 at least
with binutils-2.18, gcc-4.2.2 glibc-2.7-r1) then throw in distcc and let the x86 host
help with compilation. Depending on processor speed it can take a while (building
xorg-server-1.4.0.90 on the 200MHz SH4 takes 2-3 hours with distcc help), but
most of the packages in portage can be emerge fine (unless you run into
gcc/binutils bugs or code which assumes x86 is the only arch in the universe).

MfG,
mano

Hi Simon,

I've encountered the same error that you have, and I've posted a patch to the gentoo-embedded list:

http://archives.gentoo.org/gentoo-embedded/msg_06279.xml

The odd thing is, after compiling properly, the 'make install' portion now bails out saying that it can't find .libs/libmpfr.lai
Code:

 >>> Source compiled.
 >>> Test phase [not enabled]: dev-libs/mpfr-2.3.0_p3

 >>> Install mpfr-2.3.0_p3 into
/var/tmp/portage/dev-libs/mpfr-2.3.0_p3/image/ category dev-libs
.......
/usr/bin/install -c .libs/libmpfr.lai
/var/tmp/portage/dev-libs/mpfr-2.3.0_p3/image//usr/lib/libmpfr.la
/usr/bin/install: cannot stat `.libs/libmpfr.lai': No such file or directory
make[2]: *** [install-libLTLIBRARIES] Error 1

I guess I'll have to just copy .libs/libmpfr.la to .libs/libmpfr.lai, but I'm waiting on some input from the gentoo-embedded list to see if this is worth-while, or if there is some more elegant solution.

I have another patch which will fix the install problem mentioned before:

mpfr-2.3.0_p3-la-to-lai.patch
Code:

            $(LIBTOOL) --mode=install $(libLTLIBRARIES_INSTALL) $(INSTALL_STRIP_FLAG) "$$p" "$(DESTDIR)$(libdir)/$$f"; \


Here is a quick and dirty way you can apply the patch and emerge the file right away... adjust any of the parameters as necessary.

Code:
#!/bin/sh
SYSROOT=/usr/arm-unknown-linux-gnu
PORTAGEDIR=/usr/portage
OVERLAYDIR=${SYSROOT}/usr/local/portage/simple_patches
CAT=dev-libs
PORTAGE_CONFIGROOT=${SYSROOT}

mkdir -p ${OVERLAYDIR}/${CAT}
cd ${OVERLAYDIR}/${CAT}
cp -aR ${PORTAGEDIR}/${CAT}/mpfr .
wget -O - http://vaiprime.visibleassets.com/~cfriedt/patches/mpfr-2.3.0_p3-fix-rpath-and-lai-issues.patch | patch -p0 -i -
echo "PORTDIR_OVERLAY=\"\${PORTDIR_OVERLAY}\" ${OVERLAYDIR}" >> ${SYSROOT}/etc/make.conf

SYSROOT=${SYSROOT} xmerge -av1 =mpfr-2.3.0_p3


You can download the patch from here:

Hi,

thx for the patch. I'll try it some time. I don't need it now because i figured out that mpfr is only needed if you build gcc with the "fortran" use-flag set. So as i hope i won't need any fortran support i'll be fine.

Another question, were you able to cross compile a native gcc for arm-unknown-linux-gnu?

lg, Simon
