Subject: [PATCH] Link libunwind to libgcc_s rather than libgcc
|
||
|
|
|
||
|
|
For some architectures, -lgcc and -lgcc_s are not equivalent. On ARM for
|
||
|
|
example, libgcc_s.so.1 contains some symbols needed by libunwind which
|
||
|
|
are not present in libgcc.
|
||
|
|
|
||
|
|
This causes the following link error when building the X.Org X server
|
||
|
|
with libunwind support:
|
||
|
|
|
||
|
|
CCLD Xorg
|
||
|
|
/usr/lib/libunwind.so: undefined reference to `__aeabi_unwind_cpp_pr0'
|
||
|
|
/usr/lib/libunwind.so: undefined reference to `__aeabi_unwind_cpp_pr1'
|
||
|
|
|
||
|
|
Linking against libgcc_s explicitly solves this problem.
