Another data point... Earlier (I *think* it was this thread) someone mentioned problems with trying to build glibc with gcc 3.x and "ls" segfaulting. I've recently upgraded portions of my system (including libraries and compilers) with the packages from the Slackware 9.0 CD. I expect a certain amount of pain (due to library version conflicts) every time I go through the upgrade process, but this time the pain feels different... I absolutely cannot get getty and uugetty from the getty-ps-2.1.0 package to work: segmentation faults. Even tried building from source: no good. My old getty and uugetty binaries (version 2.0.7j) seem to work ok with the new libraries, but rebuilding the 2.0.7j code with gcc-3.2.2 results in segfaults. The behavior seems to be independent of kernel version (2.5.70-2.5.72). Here's the relevant version list (referenced libraries reported by ldd): kernel 2.5.72 glibc 2.3.1 libtermcap 2.0.8 ld-2.3.1 gcc 3.2.2 binutils 2.13.90.0.18 The Slackware default install uses agetty rather than the getty-ps package, which may partly explain why my particular symptom hasn't been reported previously (to my knowledge). I'm curious to know if this problem exists with a virgin Slackware 9 installation, and will probably have an answer by this weekend, time permitting. -- ----------------------------------------------------------------------- Bob Tracy WTO + WIPO = DMCA? http://www.anti-dmca.org rct@frus.com ----------------------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
