The wrapper's purpose is to inspect the @code{-L} and @code{-l} switches |

|
|
passed to the linker, add corresponding @code{-rpath} arguments, and |
|
|
|
invoke the actual linker with this new set of arguments. By default, |
|
|
|
the linker wrapper refuses to link to libraries outside the store to |
|
|
|
ensure ``purity''. This can be annoying when using the toolchain to |
|
|
|
link with local libraries. To allow references to libraries outside the |
|
|
|
store you need to define the environment variable |
|
|
|
@code{GUIX_LD_WRAPPER_ALLOW_IMPURITIES}. |
|
|
|
invoke the actual linker with this new set of arguments. You can instruct the |
|

wrapper to refuse to link against libraries not in the store by setting the |
|

@code{GUIX_LD_WRAPPER_ALLOW_IMPURITIES} environment variable to @code{no}. |
