[musl] Running mips64-linux-musl-native from $HOME

Hi Everyone,

I need a little help is pinpoint my mistake below. I think it may have
to do with one of the relative paths below.

I am working on GCC22 from the compile farm. I started at
https://musl.cc/. I downloaded mips64-linux-musl-native.tgz and
unpacked in $HOME with tar xzf mips64-linux-musl-native.tgz:

$ ls mips*
mips64-linux-musl-native.tgz
mips64-linux-musl-native

I attempt to compile a program:

$ cat test.cxx
#include <wchar.h>
int main(int argc, char* argv[])
{
return 0;
}

It results in:

$ ~/mips64-linux-musl-native/bin/g++ test.cxx -o
test.exetest.cxx:1:10: fatal error: wchar.h: No such file or directory
#include <wchar.h>
^~~~~~~~~
compilation terminated.

It looks like the header is present:

$ find ~/mips64-linux-musl-native/ -name 'wchar.h'
/home/noloader/mips64-linux-musl-native/include/wchar.h
/home/noloader/mips64-linux-musl-native/include/c++/8.2.0/tr1/wchar.h

If I am parsing the GCC paths used below, it looks like there is an
extra "../" in "../../../../".

I am guessing I missed a step somewhere along the line. Would anyone
be able to point out my mistake?

Jeff
