Hello All,

I've created a image based on Buildroot 2012.08 with uclibc 0.9.33 and
gcc 4.6.0.
the build passed or and now I'm trying to compile iasl from within the
image (I've chrooted into it) but for some reason it fails, see:
/acpica-unix2-20121018 # make iasl
make[1]: Entering directory `/acpica-unix2-20121018/generate/unix/iasl'
gcc -c -m32 -D_LINUX -D_GNU_SOURCE -D_FORTIFY_SOURCE=2
-I../../../source/include -DSCMP_REMOVE_UNNEEDED -Os -DACPI_ASL_COMPILER
-I../../../source/compiler -Iobj32 -Wall -Werror
-oobj32/aslcompilerlex.o obj32/aslcompilerlex.c
gcc: error trying to exec
'/usr/lib/gcc/i686-unknown-linux-uclibc/4.6.0/../../../../i686-unknown-linux-uclibc/bin/as':
execv: No such file or directory
make[1]: *** [obj32/aslcompilerlex.o] Error 1
make[1]: Leaving directory `/acpica-unix2-20121018/generate/unix/iasl'
32-bit version of iasl:
ls: ../bin32/iasl: No such file or directory
make: *** [iasl] Error 1

the strange thing is that
"/usr/lib/gcc/i686-unknown-linux-uclibc/4.6.0/../../../../i686-unknown-linux-uclibc/bin/as"
exists, see:
/acpica-unix2-20121018 # ls -l
/usr/lib/gcc/i686-unknown-linux-uclibc/4.6.0/../../../../i686-unknown-linux-uclibc/bin/as

/usr/lib/gcc/i686-unknown-linux-uclibc/4.6.0/../../../../i686-unknown-linux-uclibc/bin/as

here is the output of gcc -v:

gcc version 4.6.0 (Buildroot 2012.08)

what am I doing wrong and how I can fix it?

Thanks.
