__ia64_syscall doesn't exist. Don't use the syscallX() macros. Use syscall() instead, for example: syscall(SYS_syslog,8,NULL,<some level>), If __ia64_syscall doesn't exist why is it in /usr/include/asm/unistd.h ? More importantly why does the both the original code any my cut down example work under Turbo Linux 6.1 (IA64 edition) ? I've looked in the turbo glibc and I can see the difference, you're not exporting __ia64_syscall in the sysdeps/unix/sysv/linux/ia64/Versions file. The glibc maintainers decided it should not be exported. |
From Bugzilla Helper: User-Agent: Mozilla/4.75 [en] (X11; U; Linux 2.2.15-3SGI_39 i686) Looks like __ia64_syscall is not being exported from libc ?
