Category: Threads Group: Platform-specific Status: Open Resolution: None Priority: 5 Submitted By: Blade (blade_doyle) Assigned to: Nobody/Anonymous (nobody) Summary: HP-UX: Can't shl_load() a library containing Thread Local Initial Comment: HP-UX runtime loader does not support dynamic load of shared libraries that contain (TLS) thread local storage. As a result, when attempting to import modules that contain TLS the following error is reported: "/usr/lib/dld.sl: Can't shl_load() a library containing Thread Local Storage" This problem was discussed previously on the python.org mail list: http://mail.python.org/pipermail/python-list/2003-May/164024.html There is another option: Use LD_PRELOAD environment variable to cuase the runtime loader to 'pre-load' the pthreads library (and dependancies of the pthread library). See the dld.sl(5) man page for more info on LD_PRELOAD. But, I think a 5th option is ideal. If libpthread.sl (and the dependancies of libpthread) are linked into the python executable at build time then all of these problems are avoided. I suggest that the HP-UX (includes hp-ux on ia64) build process be modified so that libpthead (and depends) are linked in. Or, at least, make a note of this problem/solution in the HP-UX section of the README file distributed with python source. Here is the process I use to work around the TLS problem: HP-UX: bash$ BASECFLAGS="-DTHREAD_STACK_SIZE=0x50000"; export BASECFLAGS bash$ ./configure --without-gcc --enable-shared --with-libs='-lpthread -lstd_v2 -lCsup_v2 -lcl' bash$ **Edit the Makefile and remove -O from the OPT line. bash$ make bash$ make test bash$ make install HP-UX on ia64: bash$ CC=cc; export CC bash$ CXX=aCC; export CXX bash$ BASECFLAGS="+DD64 -DTHREAD_STACK_SIZE=0x50000"; export BASECFLAGS bash$ LDFLAGS="+DD64"; export LDFLAGS bash$ ./configure --without-gcc --enable-shared --with-libs="-lpthread -lCsup -lstd_v2 -lunwind" bash$ unset CC bash$ unset CXX bash$ unset BASECFLAGS bash$ unset LDFLAGS bash$ **Edit the Makefile and remove -O from the OPT line. bash$ make bash$ make test bash$ make install ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1379984&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
