It turns out that the .o files causing the problem are quite large (the result of linking a bunch of smaller ones together with "ld -r ...". By avoiding this and linking the smaller .o's directly into the executable, I can work around the bug. | | >| /usr/bin/ld: can't relax section: No such file or directory | >| collect2: ld returned 1 exit status | | This was a temporary problem. It occurs if you have a toolchain with Richard | Henderson's 2000-10-09 bfd patch for sorting unwind sections, but don't have | his 2000-10-24 bfd patch which makes it work. I never released a toolchain | with the first patch but not the second. Perhaps you got a toolchain from | someone else? Or maybe you applied random patches from some mailing list | to your toolchain? The 2.9 toolchain is stock as it came with TurboLinux 0825. The 2.96 toolchain was from your gcc-092500 snapshot with the glibc2.1.3 patch, "patch.022" and a gas and gcc patch that you sent me in email to address a WAW/WAR dependency I reported a while back. | | > gcc version 2.96-ia64-000717 snap 000925 | > GNU ld version 2.9-ia64-000717 (with BFD 2.9-ia64-000717)) | | This is 2 months obsolete. The 001117 snapshot should be used instead of this | one. When our hardware is upgraded, we plan to move to newer kernels, newer glibc's, and (I'm sure!) improved toolchains... Thanks, Steve
