When I build our application on Fedora Core 5 using gcc/ld the main library of our (quite large) application links in about 10s on an older 1.7GHz Pentium 4/Xeon system. When I build the same app on my new PCs that have gcc 4.1.1 on them, compiling is much faster, but linking is appallingly slow, about 2:30 for the same binary. Factoring 3x speed difference in hardware, this is around 18x slower!!!
I have seen at least one other report of extremely slow linking: http://www.gatago.com/gnu/g++/help/19351814.html I looked at the suggestions above: 1. this is local linking, on the local filesystem 2. I did "top" and ld is consuming 100% cpu throughout. This happens on two separate modern PCs that have had Fedora 5 + yum update (to gcc 4.1.1) done on them. Any help in trying to diagnose this is welcome. Note that every other operation I can think of on these PCs is very fast -- it is only this one operation, ld, that is extremely slow. -- Summary: ld 4.1.1 runs EXTREMLY slow compared to 4.0 Product: gcc Version: 4.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: baisa at brad-aisa dot com GCC build triplet: i386-redhat-linux GCC host triplet: i386-redhat-linux GCC target triplet: i386-redhat-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28967
