Hi,
Hi, I'm involved in a project that will use a software written in c++
with the glorious msp430. With this in mind, i try to build the mspgcc
with c++ support, without success. Searching in the archive of this
mailing list don't fix my problem. I follow the installation notes (see
mspgcc-manual from pages 48 to 50).
I have built gcc with c++ installed and I think I had it working, I have
never used it in a production environment though.
I have a gcc-3.3 built with c++ included that will build an msp430-object.
I don't think c++ in implemented on the gcc-3.2 version, and I thought
there were other issues with gcc-3.3, but you could try it.
So, get gcc-3.3.6 (core and g++), and combine with the files from the
msp430 cvs from gcc/gcc-3.4 and you should be able to build c and c++
compilers. You may need to the enable-languages=c,c++, I can't remember.
There is something is gcc/gcc-3.4 which disables libstdc++ and enables
the c++ compiler, but I don't remember what it was at the moment, a few
diff's on the directories should find it, if you want to know.
using the c++ compiler with -fno-rtti -fno-enforce-eh-specs
-fno-exceptions (the default for msp430-gcc-3.3.6) reduces the code size
considerably.
A sample of c code I have built with the c++ compiler (and -O2) turns
out the same size and compiled with the c compiler.
