[U-Boot] Compile error undefined reference to `__aeabi_unwind_cpp_pr0

[U-Boot] Compile error undefined reference to `__aeabi_unwind_cpp_pr0

[Andrew Holt]

Hi,

I am building u-boot for the TI da850_omapl138_evm using the Current CodeSourcery toolchain.

The final link, where it produces u-boot and u-boot.map failed with the following error:

/usr/local/Sourcery_G++_Lite/bin/../lib/gcc/arm-none-linux-gnueabi/4.5.2/libgcc.a(_bswapsi2.o):(.ARM.exidx+0x0): undefined reference to `__aeabi_unwind_cpp_pr0'
make: *** [u-boot] Error 1

I have seen reference to a patch, if this is true could somebody indicate which patch will fix this ?

Thanks,
Andrew

This board is *not* in u-boot mainline. We have da850_evm, and this
compiles fine.

Hi,

I performed > 

make clean && make da850_evm_config && make

And still get the same error :(

Probably a fix to your tool chain...


...or you don't use the compiler provided libgcc, and rather the
routines that come with U-Boot.

I bet you are still using the same tool chain?

Guess where the error is?

Last CodeSourcery uses a gcc 4.5 compiler (from website). I have tried
to compile the board with a gcc-4.5.1 (gcc version 4.5.1 (GCC),
ELDK-5.0), no problem at all.

Maybe something gone wrong when you installed the toolchain ?

Hi,

I have latest (from website) installed on Ubuntu 11.04.  I have built over things, including the linux distro build root without problems.  I?ll investigate but I?m not sure where to look.

With last CodeSourcery - gcc version 4.5.2 (Sourcery G++ Lite
2011.03-42) - the board is built on Ubuntu Natty without errors. I see
only a few warnings due to the libgcc of the toolchain, for example:

arm-none-eabi-ld: warning:
/home/opt/tools/CodeSourcery/Sourcery_G++_Lite/bin/../lib/gcc/arm-none-eabi/4.5.2/libgcc.a(_bswapsi2.o)
uses variable-size enums yet the output is to use 32-bit enums; use of
enum values across objects may fail

However, everything is built successfully.

Stefano Babic
