Hello list! I've built MinGW using gcc-4.7.0-release: ftp://ftp.gnu.org/gnu/gcc/gcc-4.7.0/gcc-4.7.0.tar.bz2 When trying to compile the code using the Transactional memory, I get the following message: > $ g++ tmtest.cpp -otmtest -fgnu-tm > $ error: libitm.spec: No such file or directory I've read http://gcc.gnu.org/wiki/TransactionalMemory But there is no mention of any flags that need to be specified when configuring GCC. The first question: is it necessary to specify any flags to activate TM? The second question: what kind of file 'libitm.spec' is? where can I get it? what program / script it is created by? I created a file with such a name in the directory with the code example. After that, when trying to compile the code, I get the following errors: > ccQU8ooA.o:tmtest.cpp:(.text+0x85): undefined reference to `__ITM_beginTransaction' > ccQU8ooA.o:tmtest.cpp:(.text+0x96): undefined reference to `__ITM_commitTransaction' > ccQU8ooA.o:tmtest.cpp:(.text+0xad): undefined reference to `__ITM_commitTransactionEH' > ccQU8ooA.o:tmtest.cpp:(.text+0x1a4): undefined reference to `__ITM_RU4' > ccQU8ooA.o:tmtest.cpp:(.text+0x1b3): undefined reference to `__ITM_WU4' > ccQU8ooA.o:tmtest.cpp:(.text+0x1bd): undefined reference to `__ITM_RU4' > ccQU8ooA.o:tmtest.cpp:(.text+0x1cd): undefined reference to `__ITM_cxa_allocate_exception' > ccQU8ooA.o:tmtest.cpp:(.text+0x1dd): undefined reference to `__ITM_WU4' > ccQU8ooA.o:tmtest.cpp:(.text+0x1f5): undefined reference to `__ITM_cxa_throw' > e:/mingw32/bin/../lib/gcc/i686-w64-mingw32/4.7.0/../../../../i686-w64-mingw32/bin/ld.exe: ccQU8ooA.o: bad reloc address 0x0 in section `.tm_clone_table' > collect2.exe: error: ld returned 1 exit status I googled that the symbols above are implemented in the libitm. When trying to build it (gccroot/libitm/configure), I get the following error: > configure: error: Configuration i686-w64-mingw32 is unsupported. TM is unsupported by MinGW?
