This code has a special behavior when q3map2 is a symbolic link.
|
|
|
|
For each dir in ${PATH} (example: "/usr/bin", "/usr/local/bin" if ${PATH} == "/usr/bin:/usr/local/bin"),
|
|
it looks for "${dir}/q3map2" (file exists and is executable),
|
|
then it uses "dirname(realpath("${dir}/q3map2"))/../" as installPath.
|
|
|
|
So, if "/usr/bin/q3map2" is a symbolic link to "/opt/radiant/tools/q3map2",
|
|
it will find the installPath "/usr/share/radiant/",
|
|
so q3map2 will look for "/opt/radiant/baseq3" to find paks.
|
|
|
|
More precisely, it looks for "${dir}/${argv[0]}",
|
|
so if "/usr/bin/q3map2" is a symbolic link to "/opt/radiant/tools/q3map2",
|
|
and if "/opt/radiant/tools/q3ma2" is a symbolic link to "/opt/radiant/tools/q3map2.x86_64",
|
|
it will use "dirname("/opt/radiant/tools/q3map2.x86_64")/../" as path,
|
|
so it will use "/opt/radiant/" as installPath, which will be expanded later to "/opt/radiant/baseq3" to find paks.
