[uClibc] SH4 with shared libraries

[Carl SHAW]

Has anyone managed to get the uClibc shared library loader working on
the SH4 platform recently?

I've tried the uClibc gcc 3.3.x toolchain with latest uClibc snapshot,
but when I try to run a shared app it seg faults (static compilation
works).  I've switched on the ld debugging and it appears that the fault
occurs at the end of dl-startup.c when the loader tries to transfer
control to the application with the START() macro.  The
_dl_get_ready_to_run() function is called and returns OK before that
though.  The application is just

int main(int argc, char*argv[]) { int a; a++; return 1; }

Replacing the uClibc loader with the glibc one works.

Any ideas where I can go from here?  I haven't looked at loaders before,
so simple steps or pointers to some reading material appreciated...

Thanks,
