I rebuilt ctype.o and the libraries it goes into. Unfortunately, I still get
the link error. If I compare the output of nm -A on the old and new ctype.o
objects, I don't see a difference in the defined symbols.
The mangled form of vtable for std::ctypechar is _ZTVSt5ctypeIcE. If I
grep for that in nm -A ctype.o, I see
ctype.o:17c0 d _ZTVSt5ctypeIcE.P8
but no instances without the .P8 suffix. Looking through all the objects of
libstdc++, grep only turns up these:
ctype_configure_char.o: U _ZTVSt5ctypeIcE
ctype_configure_char.o:08a4 d _ZTVSt5ctypeIcE.P8
For comparison, I grepped for _ZTVNSt6locale5facetE, the mangled form of
vtable for std::locale::facet, and got the below:
time_members.o: U _ZTVNSt6locale5facetE
time_members.o:1778 d _ZTVNSt6locale5facetE.P8
codecvt.o: U _ZTVNSt6locale5facetE
codecvt.o:15d0 d _ZTVNSt6locale5facetE.P8
locale-inst.o: U _ZTVNSt6locale5facetE
locale-inst.o:00023974 d _ZTVNSt6locale5facetE.P8

locale.o:2b08 D _ZTVNSt6locale5facetE
locale.o:2b3c d _ZTVNSt6locale5facetE.P8
The fact of the symbol being a vtable for a template class appears to be
relevant. Maybe a different kind of explicit instantiation is needed?

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53238 --- Comment #9 from Jonathan Wakely redi at gcc dot gnu.org 2012-05-09 16:44:07 UTC --- Hmm, I guess this is for the case where gthr-aix.h includes gthr-single.h, which doesn't define the C++11 interface. The configure script determined that _GLIBCXX_HAS_GTHREADS should be defined, but then that only works if gthr-posix.h gets included. A fix (maybe not the right one) would be to add the C++11 types and functions to gthr-single.h and make it define __GTHREADS_CXX0X, so that thread can be be compiled and the types found, even if the resulting classes can't actually be used in single-threaded mode. Another option would be for gthr-aix.h to #undef _GLBCXX_HAS_GTHREADS in the non-_THREAD_SAFE case, but I think that would be wrong, changing a property that should be fixed at configure time into one that depends on switches being used or not when the user compiles code. I won't be able to work on that until I'm back from holiday in two weeks, in the meanwhile --disable-libstdcxx-threads should allow you to bootstrap, or maybe just --disable-libstdcxx-pch

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53238 --- Comment #8 from Daniel Richard G. skunk at iskunk dot org 2012-05-08 18:18:04 UTC --- I did a non-bootstrap build to speed things up a bit. (The system already has GCC 4.5.2.) First: Your patch needs a couple of ;; sprinkled in there :-) Second: With the patch, after working around some unrelated integer-type issues, I get the following error: [...] Making all in include gmake[4]: Entering directory `/tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include' mkdir -p ./powerpc-ibm-aix4.3.2.0/bits/stdc++.h.gch /tmp/gcc-4.7.0/_build/./gcc/xgcc -shared-libgcc -B/tmp/gcc-4.7.0/_build/./gcc -nostdinc++ -L/tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/src -L/tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/src/.libs -B/opt/tg/powerpc-ibm-aix4.3.2.0/bin/ -B/opt/tg/powerpc-ibm-aix4.3.2.0/lib/ -isystem /opt/tg/powerpc-ibm-aix4.3.2.0/include -isystem /opt/tg/powerpc-ibm-aix4.3.2.0/sys-include-x c++-header -nostdinc++ -g -O2 -I/tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/powerpc-ibm-aix4.3.2.0 -I/tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include -I/tmp/gcc-4.7.0/libstdc++-v3/libsupc++ -O2 -g -std=gnu++0x /tmp/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h \ -o powerpc-ibm-aix4.3.2.0/bits/stdc++.h.gch/O2ggnu++0x.gch In file included from /tmp/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:102:0: /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:62:13: error: '__gthread_cond_t' does not name a type /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:67:5: error: '__native_type' does not name a type /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:71:13: error: '__native_type' does not name a type /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:141:5: error: 'native_handle_type' does not name a type /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable: In member function 'std::cv_status std::condition_variable::__wait_until_impl(std::unique_lockstd::mutex, const std::chrono::time_point_Clock, _Duration)': /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:157:2: error: '__gthread_time_t' was not declared in this scope /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:157:19: error: expected ';' before '__ts' /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:163:28: error: '_M_cond' was not declared in this scope /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:164:7: error: '__ts' was not declared in this scope /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:164:11: error: there are no arguments to '__gthread_cond_timedwait' that depend on a template parameter, so a declaration of '__gthread_cond_timedwait' must be available [-fpermissive] /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/condition_variable:164:11: note: (if you use '-fpermissive', G++ will accept your code, but allowing the use of an undeclared name is deprecated) In file included from /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/future:41:0, from /tmp/gcc-4.7.0/libstdc++-v3/include/precompiled/stdc++.h:104: /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread: At global scope: /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:63:13: error: '__gthread_t' does not name a type /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:70:7: error: 'native_handle_type' does not name a type /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:76:29: error: expected ')' before '__id' /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:174:5: error: 'native_handle_type' does not name a type /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread: In constructor 'std::thread::id::id()': /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:73:23: error: class 'std::thread::id' does not have any field named '_M_thread' /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread: In function 'bool std::operator==(std::thread::id, std::thread::id)': /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:84:36: error: 'class std::thread::id' has no member named '_M_thread' /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:84:51: error: 'class std::thread::id' has no member named '_M_thread' /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread:84:60: error: '__gthread_equal' was not declared in this scope /tmp/gcc-4.7.0/_build/powerpc-ibm-aix4.3.2.0/libstdc++-v3/include/thread: In function 'bool std::operator(std::thread::id,

I'm starting a new build to test the patch. This AIX machine runs rather slow, so I'll need a few days to get back to you; please hold tight!

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53238 --- Comment #4 from Daniel Richard G. skunk at iskunk dot org 2012-05-05 16:05:30 UTC --- (In reply to comment #3) If you're using --enable-thread=posix then it should be defined. I haven't used --enable-thread=posix, and if I invoke .../xgcc -v, I see Thread model: aix. So it seems the test passes because _PTHREADS is not defined. Shouldn't the cpp conditional in the test be written as #if !defined(_PTHREADS) || !defined(_POSIX_TIMEOUTS) || _POSIX_TIMEOUTS = 0 ?

Your suggestion would work for the posix and aix thread models, but would break e.g. win32, where _PTHREADS won't be defined but mutexes always support timeouts (not that anyone has actually added __ghtread_mutex_timedlock to gthr-win32.h yet, but they should do) I think the right thing to do is define _PTHREADS for the aix thread model, could you test this patch? I've assumed that _THREAD_SAFE might be needed to enable some thread-related features on AIX, I don't know if that's true. An alternative patch would simply change the case statement to match posix|aix)

I'm a little mystified as to why this test is relying entirely on feature test macros, instead of checking for the existence of pthread_mutex_timedlock directly...
