I decided to switch to code sourcery external toolchain, to try and narrow the
cause to see if it was indeed a compiler issue.
Which building with the mentor-2012.03-71-powerpc-mentor-linux-gnu.bin
toolchain, I get a bunch of failures similar to the one shown below:
| ./.libs/libsqlite3.so: undefined reference to `__gcc_qtod'
| ./.libs/libsqlite3.so: undefined reference to `__gcc_qneg'
| ./.libs/libsqlite3.so: undefined reference to `__gcc_qge'
| ./.libs/libsqlite3.so: undefined reference to `__gcc_qlt'
| ./.libs/libsqlite3.so: undefined reference to `__gcc_itoq'
| ./.libs/libsqlite3.so: undefined reference to `__gcc_qtoi'
| ./.libs/libsqlite3.so: undefined reference to `__gcc_qgt'
| ./.libs/libsqlite3.so: undefined reference to `__gcc_dtoq'
My target process is a PowerPC 440 with no hardware floating point unit, and my
ppc440 tune has been setup to use software floating point.
The above errors appear to somehow related to the floating point type.
How can I get past these type of errors? I don't get these errors with
gcc-4.5.1, 4.6 and 4.7 recipes. It only appears with the mentor sourcery cross
compiler for powerpc.
Getting yocto to build using the sourcery toolchain for the powerpc440, might
yield some clues for narrowing down the issue related with the dynamic linker.
