Hello,
I would like to compile two version of Gambit on my computer, one for C "gsc", and another for C++ "c-plusplus-gsc". Is it possible to add an option to "configure" to have a "c-plusplus-" prefix (or something similar) in front of the programs?
Thanks,

Why do you want this? I'm asking because the "c-plusplus-gsc" and "gsc" would have the same input/output behavior because the output (.c file) is code that conforms to C *and* C++. You would see a difference if you are loading dynamically compiled modules into "gsc" but I suspect that is not a common thing.
Where there is an important difference it is in the runtime library that is constructed. Another important difference is if your are compiling with the "-dynamic" flag (but then the only difference is the C or C++ compiler that is called by the ~~/bin/gsc-cc-o script that is called by gsc).
What I'm getting at is that to get what you want you should build the Gambit system twice, and install it in two different directories:
./configure --prefix=/u/me/gc make make install make mostlyclean ./configure --prefix=/u/me/gc++ --enable-cplusplus make make install
and then add /u/me/gc/bin and /u/me/gc++/bin to you path, and rename the binaries in /u/me/gc++/bin as needed (gsc -> c-plusplus-gsc, ...).

Hi,
thank you for your answer. I include Scheme code as a dynamic library in C and C++ programs, that's why I asked the question. With your answer I'm not worried anymore about compatibility issues, so I'll stay with the normal configuration.
Cheers,
