Hi
My 2 cents. That i386-elf GCC build has not `libgcc_eh.a' library
find /opt/ecos/gnutools/i386-elf/ -name libgcc_eh.a
<< no output >>
but the library is "used" for synth
hal/synth/arch/current/src/synth.ld:
#if (__GNUC__ >= 3)
GROUP(libtarget.a libgcc.a libsupc++.a libgcc_eh.a)
#else
GROUP(libtarget.a libgcc.a)
#endif
Can we manage the check the above with CDL?
Because 2 odd? steps to make synth tests are necessary
1) Import this option
cdl_option CYGBLD_GLOBAL_COMMAND_PREFIX {
user_value i386-elf
};
2) Workaround for the absent libgcc_eh.a in ld GROUP
sed -i 's/ libgcc_eh.a//' install/lib/target.ld
