I have to compile some c++ programs with musl-gcc wrapper and so i need c++ headers and libs. Before i can i use them, i guess that i have to compile the libstdc++ source against musl, with musl-gcc itself.

I got the libstdc++ source from the latest version of gcc source and, according to this guide all i have to do is to run configure specifing the compiler path (that is /usr/local/musl/bin/musl-gcc) as the --host option argument

However, the configure fails and i get the error 

cannot find install-sh, install.sh, or shtool in "../<folder name>/libstdc++-v3" "../<folder name>/libstdc++-v3/.." "../<folder name>/libstdc++-v3/../.."

Am I missing some step?

libstdc++ can only be built as a part of gcc distribution, it can't be built standalone. So, at first, you need full gcc source distribution.

When you get it, you still will not be able to build libstdc++ simply as ./configure --host=.... It is closely tied with gcc itself; you will have to adjust configure args and modify configure scripts (at least acinclude.m4, configure.ac).
