Hi All,
while compiling uClibc++ against uClibc-nptl, I found a problem
into the linker script libc.so.
The uClibc++ needs the __tls_get_addr symbol (TLS enabled), but it
cannot find
it because the dynamic linker is not present into the linker script libc.so.
In the same way, a lot of applications using TLS dynamic access model
will fail
linking with uclibc-nptl
This patch solves this issues defining into Rules.mak the ASNEEDED variables
only for the NPTL case.
It could be worth to add it both into trunk and nptl branch
Regards,
Carmelo
This patch fixes the link script libc.so adding an AS_NEEDED
entry for the dynamic linker. This is required at least to
resolve the __tls_get_addr symbol used in TLS dynamic access model.
