Hi John,

We currently have a platform which uses an M5233 nommu Coldfire with
uClinux using a 2.6.17 kernel with uClibc 0.9.27, bFLT executables and
no shared library support. The compiler set we are using is the 4.1.1
compiler set as distributed from the uclinux.org website and it works
well for programming in C. Recently we have a need to program in C++ so
I have been trying to get the g++ compiler to generate a valid
executable. The compile works fine but when I run, I always get :
BINFMT_FLAT: reloc outside program 0xff9b0d01 (0 - 0x84f54/0x51060),
killing helloworld!
I seem to recall a few problems with c++ code generation from that
gcc-4.1.1 based toolchain. I think the answer for most people was
to use the code sourcery toolchains, which seemed to get this right.

and a SIGSEGV. The application is simply hello world as follows:
#include <iostream>
int main (int argc, char **argv)
{
std::cout << "Hello World\n";
return 0;
}
The compile and link step are as follows:
m68k-elf-g++ -m5307 -DCONFIG_COLDFIRE -I../../include -g -O0 -pipe
-fno-common -fno-builtin -Wall -Wno-strict-aliasing -DEMBED -msep-data
-Dlinux -D__linux__ -Dunix -D__uClinux__ -c -o helloworld.o helloworld.C
m68k-elf-g++ -m5307 -DCONFIG_COLDFIRE -I../../include -g -O0 -pipe
-fno-common -fno-builtin -Wall -Wno-strict-aliasing -DEMBED -msep-data
-Dlinux -D__linux__ -Dunix -D__uClinux__ -L../../lib/morey
-Wl,--fatal-warnings -Wl,-elf2flt -Wl,-move-rodata -msep-data -lstdc++
-o helloworld helloworld.o
It seems that no matter what compile and link options I use the result
is the same. I have also tried increasing the stack size to as large as
256K with no change . I searched around and found many methods that
people have used to solve this problem and have tried pretty much every
one but nothing seems to change the result. Is there possibly an issue
in the elf2flt conversion that is causing this issue?
Any ideas on how to eliminate this issue would be appreciated.
