This is a hack that, combined with g-ir-scanner-wrapper, allows us to put
|
|
/usr/lib inside LD_LIBRARY_PATH before all the other paths that g-ir-scanner
|
|
appends. This is very important, because if we don't put /usr/lib first, the
|
|
cross base will be first and during certain circumstances (musl, cross-endian)
|
|
the compiler will fail to execute.
|
|
|
|
We cannot use another way to append it, because we don't want to put /usr/lib
|
|
inside the library paths for scanning - we don't want the gi scanner to
|
|
process any of these libs. We just want the native executables to run
|
|
correctly.
|
|
|
|
As for using the literal LD_LIBRARY_PATH inside the environment - the scanner
|
|
will actually read it, but it will put it at the *end*, which does not help
|
|
us.
