First, note I used setup to update to the "current" versions of everything, apparently 1.5.17-1 (reported by cygcheck, and the source tarball). I also have to do rebaseall since I use KDE. OK, I did ./configure;make;make install... 29716 [main] ? 4056 multiple_cygwin_problem: cygheap base magic number mismatch detected - 0x6182/0x0 If I try to rebase it, nothing works and I get a bigger error message. If it is a rebase problem, is there any way to get the current address (from /bin/cygwin1.dll) so I can set the built one to it? Even if I strip the newly made dll, it isn't the same size as the release version. Are there instructions anywhere to build an exact copy of the release. I need to change exactly one byte in trace.o(.cc) so PTHREAD_MUTEX_DEFAULT will be different to see if this fixes my problem. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
PTHREAD_MUTEX_DEFAULT different for cygwin v.s. linux.
I have a problem similar to that of: http://sourceware.org/ml/cygwin/2005-05/msg01400.html I have an old system that I'm trying to port that uses pthreads, but doesn't set the attribute, and a non-owner thread will destroy the thread in a deallocate routine, but this won't happen (it won't actually destroy the thread). The problem is that (in pthread.h) PTHREAD_MUTEX_DEFAULT is .._NORMAL on linux, the system was originally written for. It works but eventually dies when it runs out of threads or mutexes or something since it can't recycle. PTHREAD_MUTEX_DEFAULT is .._ERRORCHECK on cygwin. It would be painful to add a whole section to create an attribute structure just to set this to be the same as linux. I can't seem to build the cygwin1.dll so I could replace it (are there any instructions on how to create an identical copy to the release? I didn't see any on the FAQ, and ./configure;make generates a file 8x larger, and it complained about something with the address). I think just changing it in the pthread.h and recompiling the dll will fix it. Note that the attribute is invisible since you need not bother with the attr structure and parameter when doing defaults. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
