Dear Jakub, Thanks for your response. No, it was not rawhide. I never use rawhide. It turns out that I had inadvertently included two "testing" repos in /etc/yum.repos.d, which turned out to have available glibc-2.4.90 glibc-common-2.4.90 and glibc-headers-2.4.90 which yum check-update found so I updated them. However gcc uses glibc-devel, which still is version 2.4-8, which does not work with the later versions listed above for the other glibc packages. (This was not detected by yum!) So laboriously, using straight rpm -Uvh --oldpackage (I don't know how to make yum install old packages), I replaced the three listed above with 2.4-8 versions, and re-installed gcc-4.1.1-1.fc5 (and the similar gcc-g++), and now everything works. Oh, of course I also deleted the "testing" repos from /etc/yum.repos.d, a lesson for the day. -- Peter ===================================================== On Aug 09, 2006 at 1:51 am, Jakub Jelinek wrote: | On Tue, Aug 08, 2006 at 05:37:32PM -0700, Peter Scott wrote: | > I have experienced a recent problem: After updating glibc | > (using yum update glibc) I'm finding I can no longer compile C | > programs; they fail to link, yielding the error message | > | > /usr/lib/../lib64/libm.so: file not recognized: File format | > not recognized | > collect2: ld returned 1 exit status | | That sounds like you upgraded to rawhide glibc on FC5; don't do that. | You'd need to upgrade several other packages as well, at least binutils, | prelink, gdb, elfutils. | | Jakub | | -- | fedora-list mailing list | fedora-list@xxxxxxxxxx | To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list | -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
