You need in your .cabal file: library: ghc-options: -optl-fuse-ld=gold ld-options: -fuse-ld=gold executable myExecutable ghc-options: -optl-fuse-ld=gold ld-options: -fuse-ld=gold (Note you might want to pass these flags to stack/cabal/Setup.hs on … Read more
Here is a demo, for GNU ld, of the difference between -L and -rpath-link – and for good measure, the difference between -rpath-link and -rpath. foo.c #include <stdio.h> void foo(void) { puts(__func__); } bar.c #include <stdio.h> void bar(void) { puts(__func__); } foobar.c extern void foo(void); extern void bar(void); void foobar(void) { foo(); bar(); } main.c … Read more
At the moment it is compiling bigger projects on Ubuntu 10.04. Here you can install and integrate it easily with the binutils-gold package (if you remove that package, you get your old ld). Gcc will automatically use gold then. Some experiences: gold doesn’t search in /usr/local/lib gold doesn’t assume libs like pthread or rt, had … Read more
