Hi,

I'm getting this error when I try to run a gcj exe on my target (arm-linux, cpu PXA270):

./a.out: can't resolve symbol '_Unwind_Backtrace'

Here is my configure:

 Using built-in specs.
Reading specs from /root/tmp/f8/uCinstall/lib/gcc/arm-linux-uclibcgnueabi/4.3.0/../../../../arm-linux-uclibcgnueabi/lib/libgcj.spec
rename spec startfile to startfileorig
rename spec lib to liborig
Target: arm-linux-uclibcgnueabi
Configured with: ../configure --prefix=/root/tmp/f8/uCinstall --with-sysroot=/root/tmp/buildroot/build_arm/staging_dir --disable-libssp --disable-libgomp --disable-libmudflap --enable-libgcj --disable-bootstrap --disable-multilib --disable-static --disable-sjlj-exceptions --target=arm-linux-uclibcgnueabi --enable-languages=c,c++,java --with-build-time-tools=/root/tmp/buildroot/build_arm/staging_dir/usr/arm-linux-uclibcgnueabi/bin --with-ld=/root/tmp/buildroot/build_arm/staging_dir/usr/arm-linux-uclibcgnueabi/bin/ld --with-nm=/root/tmp/buildroot/build_arm/staging_dir/usr/arm-linux-uclibcgnueabi/bin/nm --with-strip=/root/tmp/buildroot/build_arm/staging_dir/usr/arm-linux-uclibcgnueabi/bin/strip --with-as=/root/tmp/buildroot/build_arm/staging_dir/usr/arm-linux-uclibcgnueabi/bin/as --disable-__cxa_atexit --enable-target-optspace --disable-nls --with-gmp=/root/tmp/buildroot/toolchain_build_arm/gmp --with-mpfr=/root/tmp/buildroot/toolchain_build_arm/mpfr
Thread model: posix
gcc version 4.3.0 (GCC)

Any help please?

Should I add to configure floating point info (--with-float=soft) and/or cpu info (-mcpu=xscale -mtune=xscale)?


Thank you,

Francesco
