| 2021-04-07 09:03:50 | <timCF> | Hello! Any users of gold linker instead of standard ld in Haskell projects? I'm getting very strange situation - I have a packages A and B. Package B depends on A. I'm using gold linker in both (through ghc flags in package.yaml and cabal files). Package A is a library, no problems with builds and tests. But when I'm trying to compile package B which depends on A - I'm getting linker error |
