Hi, I don't know if coldfire users have the same experience, but I haven't been able to run any C++ app using the uclinux.org provided 4.1.1 toolchain. I always get the 'relocation' error. If I want to run C++ apps, I use the CodeSourcery toolchain version 4.2-8(free at their website).
I build as follows (-D could probably be omitted, I borrowed them from how the userapps were built in the source tree): m68k-uclinux-g++ -m5307 -pipe -fno-common -fno-builtin -Wall -msep-data -O1 -DCONFIG_COLDFIRE -DEMBED -Dlinux -D__linux__ -Dunix -D__uClinux__ -Isrc/cpp_quick_sort/cpp_quicksort_numbers -c src/cpp_quick_sort/cpp_quicksort_numbers/cpp_quicksort_numbers.cpp -o objs/qsortnum_m68k_Oyes/cpp_quicksort_numbers.o m68k-uclinux-g++ -m5307 -DCONFIG_COLDFIRE -Wl,--fatal-warnings -Wl,-elf2flt -Wl,-move-rodata -msep-data -o objs/qsortnum_m68k_Oyes/qsortnum_m68k_Oyes.bflt objs/qsortnum_m68k_Oyes/cpp_quicksort_numbers.o -lpthread Harry On 8/13/07, Bob Grimes <[EMAIL PROTECTED]> wrote: > > Hi, > > I'm trying to link a fairly simple C++ user application for ColdFire, > and I get errors relating to __cxa_guard_acquire and > __cxa_guard_release.
