Re: C/C++ Support

I have tried to build using cygwin in a Win11 environment.

The Win PATH variables contains the path to the location of the shared 
libraries, C:/cygwin64/lib/gcc/x86_64-pc-cygwin/12/.

The build command I use is:

         C:\cygwin64\bin\g++.exe -c *.cpp

And when I use cygpath -u 'C:\cygwin64\bin\g++.exe' 
becomes/usr/bin/g++.exe -c *.cpp, and /usr/bin/g++.exe exists.

On a build I get:

C:/cygwin64/lib/gcc/x86_64-pc-cygwin/12/cc1plus.exe: error while loading 
shared libraries: ?: cannot open shared object file: No such file or 
directory

Doing cygpath -w 'C:/cygwin64/lib/gcc/x86_64-pc-cygwin/12/' becomes 
/usr/lib/gcc/x86_64-pc-cygwin/12 and 
/usr/lib/gcc/x86_64-pc-cygwin/12/cc1plus.exe exists.

My guess is that g++ can't find cc1plus.exe, or that cc1plus.exe can't 
find the shared libraries, but I don't understand why not. PATH includes 
the shared libraries, and I suspect that cc1plus.exe either has the path 
hard coded or looks at PATH.

The email below that Ulf was able to use Netbeans in a Linux environment 
to, at least, build, clean and execute code, but I can't seem to get the 
same result in Windows. Does anyone know why?

As a separate question, is there any reason that compiling a single file 
is not allowed?

thanks;
art
