I see the following fails on arm-linux-gnueabi,
result of ldd build-git/arm/gdb/testsuite/gdb.threads/dlopen-libpthread.so is 1
output of ldd build-git/arm/gdb/testsuite/gdb.threads/dlopen-libpthread.so is not a dynamic executable
child process exited abnormally
FAIL: gdb.threads/dlopen-libpthread.exp: ldd dlopen-libpthread.so
FAIL: gdb.threads/dlopen-libpthread.exp: ldd dlopen-libpthread.so output contains libs
the test script invokes ldd (on host) for the target libraries, which
is wrong. ldd can't be cross because it invokes dynamic linker with
LD_TRACE_LOADED_OBJECTS and gets the dependent libraries. My first
reaction to this problem is to execute ld.so on the target (like
remote_exec target). When I start to hack proc build_executable_own_libs,
I find it has assumptions here and there that the native testing is
performed. Then I check the callers of build_executable_own_libs,
and they are all skipped if isnative is false. It is reasonable to do
the same in dlopen-libpthread.exp too.
gdb/testsuite:
2014-09-30 Yao Qi <yao@codesourcery.com>
* gdb.threads/dlopen-libpthread.exp: Skip it if isnative is
false.
Gary Benson <gbenson@redhat.com>
* lib/gdb.exp (build_executable_from_specs): Use gdb_compile_pthread,
gdb_compile_shlib or gdb_compile_shlib_pthreads where appropriate.
* lib/prelink-support.exp (build_executable_own_libs): Allow INTERP
to be set to "no" to indicate that no ld.so copy should be made.
* gdb.base/break-interp.exp (solib_bp): New constant.
(reach_1): Use the above instead of "_dl_debug_state".
(test_attach): Likewise.
(test_ld): Likewise.
* gdb.threads/dlopen-libpthread.exp: New file.
* gdb.threads/dlopen-libpthread.c: Likewise.
* gdb.threads/dlopen-libpthread-lib.c: Likewise.
* gdb.base/solib-corrupted.exp: Disable test if GDB is using probes.
