== Troubleshooting == | |||
When compiling software which links against local files (e.g. when compiling with rust's cargo), you may encounter the following problem: | |||
<syntaxHighlight lang=bash> | |||
= note: impure path `/[...]' used in link | |||
</syntaxHighlight> | |||
This happens due to a specialty in nix: <code>ld</code> is wrapped in a shell script which refuses to link against files not residing in the nix store, to ensure purity of builds. Obviously this is not useful when building locally, for example in your home directory. To disable this behavior simply set | |||
<syntaxHighlight lang=bash> | |||
NIX_ENFORCE_PURITY=0 | |||
</syntaxHighlight> | |||
in the nix-shell. | |||
