This is done by a simple configuration change setting that you can do yourself too. In `$nim/config/nim.cfg` replace `pkgs` by `pkgs2`. -- There is a new switch `--nimMainPrefix:prefix` to influence the `NimMain` that the - compiler produces. This is particularly useful for generating static libraries. |
