Fwd: Cannot build uclibc++ against toolchain (dl_iterate_phdr & __tls_get_addr)

[Flemming Madsen]

Hello

First of all: Thank you for all this wonderful stuff!

I am having trouble building uclibc++ with uclibc for the ARM platform.
Upon linking the .so file i get the output below.

It seems that the eh_globals.o and unwind-dw2-fde-glibc.o files are
extracted from gcc libraries, but that they contain references to functions
that are not part of uClibc (Not libc.so anyway)

I have tried to enable sjlj (setjmp() longjmp()) exceptions and new thread
libraries in the buildroot config but this does not seem to help.

I am using gcc 4.2.4 and uClibc 0.9.29 since these were the buildroot
defaults (Full .config attached)

Any help on this will be very much appreciated.

TIA
/Flemming
