distccd failed to exec with “No such file or directory”

And you think your compile box using distccd is ready you start emerge in your server/desktop/laptop and the first package is OK, the your emerge is using the distccd properly and the compilation is distributed to the compile box get compiled.
But just then another package gets a warning during build time:

distcc[9356] (dcc_build_somewhere) Warning: failed to distribute, running locally instead

So everything is back in your machine not in the compile box! And you find in the logs of the distccd compile box:

Ahh you missed a package, then you emerge it fast with (assumed you used Gentoo, but the solution is valid for all distros)

[root@local ]# emerge -v sys-devel/clang sys-devel/clang-runtime

And start up the build process again (if Gentoo with emerge) and again the same situation? Again the same error, but you have the “x86_64-pc-linux-gnu-clang++” command and when you type x86_64-pc-linux-gnu-clang++ it executes properly! So what is the problem? The problem is that x86_64-pc-linux-gnu-clang++ is not in the current environment PATH:

compile ~ # whereis x86_64-pc-linux-gnu-clang++
x86_64-pc-linux-gnu-clang++: /usr/lib64/llvm/5/bin/x86_64-pc-linux-gnu-clang++

The solution is very simple just restart “distccd”. A trivial one, but could save you time next time! If you install a package, which is expected to be used with distccd restart distccd!!!

Under Getnoo:

compile ~ # /etc/init.d/distccd restart
 * Caching service dependencies ...
 * Stopping distccd ...  [ ok ]
 * Starting distccd ...  [ ok ]
compile ~ #

* You might get error for another file, check if it exists if not install it and then restart the distccd daemon, for example you could get error for any of these:
