gpgrt-config doesn't work well with PKG_CONFIG_LIBDIR="" and setting PKG_CONFIG_PATH
Closed, ResolvedPublic


gpgrt-config runs emulating pkg-config.

pkg-config supports PKG_CONFIG_PATH and PKG_CONFIG_LIBDIR environment variables.

Specifically, when PKG_CONFIG_LIBDIR is empty and PKG_CONFIG_PATH is defined, gpgrt-config should search *.pc files by PKG_CONFIG_PATH, ignoring --libdir option.

Here is a possible fix:

   if [ -z "$PKG_CONFIG_PATH"  ]; then

If we could assume Bash, we can use test with -v, but it's not portable.
Also, we can't use printenv, it's not POSIX command.

The fix works for me (using bash on openSUSE Tumbleweed).
