[Buildroot] Busybox build fails with external toolchain

[Michel Benoit]

Hi,

I'm trying to use buildroot to build a rootfs with an external
toolchain based on uclibc.
I'm using buildroot svn revision 23768
The toolchain is based on gcc 4.1.2.

> arm-linux-gcc -v
Using built-in specs.
Target: arm-linux-uclibc
Configured with:
/home/danov/ronetix/buildroot/toolchain_build_arm/gcc-4.1.2/configure
--prefix=/home/danov/ronetix/buildroot/build_arm/staging_dir
--build=i386-pc-linux-gnu --host=i386-pc-linux-gnu
--target=arm-linux-uclibc --enable-languages=c,c++
--disable-__cxa_atexit --enable-target-optspace --with-gnu-ld
--with-gmp=/home/danov/ronetix/buildroot/toolchain_build_arm/gmp
--with-mpfr=/home/danov/ronetix/buildroot/toolchain_build_arm/mpfr
--enable-shared --enable-threads --disable-multilib
Thread model: posix
gcc version 4.1.2


With "make menuconfig" I configure an external toolchain and set the
toolchain path to "~/Projects/eaclock/sw/tools/arm-linux-uclibc".

When I run "make" busybox compiles ok but then it appears to choke
when linking against the libraries.

Could there be a problem with the path to the libraries?
The -L option seems to be correct in EXTRA_CFLAGS.
The busybox build starts with the output:

/usr/bin/make -j1

Any ideas with the busybox build fails?

Thanks,

Michel

The external toolchain stuff is known to be kinda flaky - But maybe
your problem is the ~ - Could you try with an absolute path to the
external toolchain?

Then if you still experiment problems you should try applying the
patch attached to this bug report

 Bernhard> '~' != $HOME unless

Indeed, that's what I thought. There might be other packages having
issues with ~ as well though, so better use the full path instead.
