There is a run-time and a build-time component for the streads: /usr/include/pthread.h == Linux threads /usr/include/nptl/pthread.h == NPTL /usr/lib/libpthread.so is a script that points to /lib/libpthread.so.0 /usr/lib/nptl/libpthread.so is a script that points to /lib/tls/libpthread.so.0
By default on RHEL (2.4.21 kernel) a simple compile: gcc foo.c -o foo -pthread Seems to run under NPTL. export LD_ASSUME_KERNEL=2.4.19 Causes the program to run under Linux Threads since LD_ASSUME_KERNEL does affect the dynamic linker. The question comes down to a build. I want to force the build to a Linux Threads environment so I do not have to set LD_ASSUME_KERNEL=2.4.19. The issue is that there appears to be a dlopen(2) issue with the RHEL 3.0 version of NPTL. The actual code I'm working with takes over 8 hours to build on an ia64. I want to force it to be fully Linux Threads. I don't want to have to specifically point to /lib/libpthread.so.0 if I don't have to. --- Note I have an RHEL 4 system I plan to run a test on, but it does not have the build sources on it yet. RHEL 4 does have a 2.6 kernel. -- Jerry Feldman <[EMAIL PROTECTED]> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9 _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
