libxml2-2.9.0 on AIX6.1 using XL C "threads.c", line 918
Last modified: 2021-07-05 13:26:20 UTC
I'm using ftp://xmlsoft.org/libxml2/libxml2-2.9.0.tar.gz AIX 6.1.0.0 with XL C/C++ using C++ compiler xlC_r specifics: export CC="xlC_r -ma -O3 -qstrict -qoptimize=3 -qmaxmem=16384" export CXX="xlC_r -ma -O3 -qstrict -qoptimize=3 -qmaxmem=16384" export CFLAGS="-I /usr/local/include" export LDFLAGS="-L /usr/local/lib -lm -ldecNumber" export CPPFLAGS=$CFLAGS export CXXFLAGS=$CFLAGS cd libxml2-2.9.0 ./configure make clean;make;make install; I get the following: make all-recursive Making all in include Making all in libxml Target "all" is up to date. Target "all-am" is up to date. Target "all" is up to date. Making all in . CC threads.lo "threads.c", line 918.20: 1506-046 (S) Syntax error. "threads.c", line 918.20: 1506-277 (S) Syntax error: possible missing ';' or ','? make: 1254-004 The error code from the last command is 1. which is: #ifdef HAVE_PTHREAD_H if ((libxml_is_threaded) && (pthread_key_delete != NULL)) pthread_key_delete(globalkey); 918: once_control = PTHREAD_ONCE_INIT; It does look like configure is using pthreads... Thanks, --dave http://dave.thehorners.com/
Same thing: threads.c:918:20: error: expected expression once_control = PTHREAD_ONCE_INIT; ^ /usr/include/pthread.h:245:27: note: expanded from macro 'PTHREAD_ONCE_INIT' #define PTHREAD_ONCE_INIT {_PTHREAD_ONCE_SIG_init, {0}} OS X: 10.7.5-i386 Xcode: 4.5.2 CLT: 4.5.0.0.1.1249367152 LLVM-GCC: build 2336 Clang: 4.1 build 421
the aix docs even reference the pthread_once_t structure, and the PTHREAD_ONCE_INIT structural init macro... http://pic.dhe.ibm.com/infocenter/aix/v6r1/index.jsp?topic=%2Fcom.ibm.aix.genprogc%2Fdoc%2Fgenprogc%2F1time_initializations.htm on line 148 you can see we are already setting the once_control to PTHEAD_ONCE_INIT.. +148 static pthread_once_t once_control = PTHREAD_ONCE_INIT; So, I commented out line 918, and it seems to be working! Good luck, --dave http://dave.thehorners.com/
We have a patch for this in git, that will be fixed in 2.9.1 : http://git.gnome.org/browse/libxml2/commit/?id=3f6cfbd1d38d0634a2ddcb9a0a13e1b5a2195a5e Could you confirm that fixes your problem on AIX ? Daniel
I can confirm that Daniel's patch worked for me on Mac OS X 10.9.3 and: > clang --version Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) Target: x86_64-apple-darwin13.2.0 Thread model: posix
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/libxml2/-/issues/ Thank you for your understanding and your help.
