ABI compatibility checker for shared libraries with symbol versioning.
|
|
|
|
shlib-compat uses dwarf debugging symbols to recreate definitions of
|
|
exported symbols, including function arguments and structural types.
|
|
|
|
The shlib-compat.py script requires devel/dwarfdump port to be
|
|
installed.
|
|
|
|
|
|
Syscalls in libc are implemented as assembly stubs and thus have no
|
|
debugging symbols attached. To enable sysfake stubs rebuild libc
|
|
adding the following to /etc/make.conf:
|
|
|
|
.if ${.CURDIR:M/usr/src/lib/libc}
|
|
.include "../../tools/tools/shlib-compat/Makefile.sysfake"
|
|
.endif
|
|
|
|
To compare libc.so versions compiled with sysfake stubs:
|
|
./shlib-compat.py -v --alias-prefix __sysfake_ \
|
|
--alias-prefix __sysfake_freebsd8_ \
|
|
--exclude-ver FBSDprivate \
|
|
--out-orig out-orig.c --out-new out-new.c libc.so.7.orig libc.so.7.new
