Hi, I'm trying to install GCC 4.2.1 on x86_64_unkown-linux-gnu (Linux 2.6.9-55.0.2.ELsmp x86_64 GNU/Linux). After building compiler and run-time libs, I ran tests (make -k check) and had failures as follows: FAIL: libgomp.c/atomic-2.c (test for excess errors) Excess errors: /tmp/ccMiztgb.s:47: Error: no such instruction: `cmpxchg16b ld(%rip)' WARNING: libgomp.c/atomic-2.c compilation failed to produce executable More details from log file can be found below. There's gcc 3.4.6 in my system and I wanted to install 4.2.1 under my personal area. Has anyone had the similar issue? Please let me know. Thanks.
