Redirection
IDO recomp currently has two forms of path redirection, both involving the /usr folder.
/usr/lib
In order for users to not having to worry about installing the binaries in particular locations in /usr/lib, recomp automatically redirects /usr/lib/ paths. This is done by determining the location of cc and redirecting to the same directory. This does mean all the binaries and err.english.cc are expected to be a part of a single flattened directory.
It is also possible to override the auto redirect by using the environment variable USR_LIB with the desired redirection path. This can be used if the binaries are not in a flattened directory with cc or if on Linux and are unable to read /proc/self/exe.
Wrapper functions implementing this redirection:
init_filewrapper_execvp
/usr/include
The other form of redirection is completely optional and is done by setting the environment variable USR_INCLUDE to the desired redirection path. This will than redirect all opened files files there. This is done so that the mdebug section file paths will still use /usr/include path, but the files themselves can be located elsewhere for greater flexibility.
