Re: Sun compilers: acc vs. gcc?

I was using the acc compiler (SC1.0.1) and switched over to gcc for a
couple of reasons. The gcc compiler has better error messages and with
-Wall it covers a broader range of circumstances I like to be warned
about. With gcc you have better control over what the compiler does.
If you have to debug a program :-), I prefer gdb over dbx (was well as
xxgdb over dbxtool).


I found that acc was giving me messages because the header files as
defined by Sun do not follow the ANSI standard (memcpy and memcmp
should use void * but Sun defines them as char *).


I would assume that the acc compiler would be better at code
optimization (especially with floating point operations) but I have
never tried it out.


You might look into SPARCworks. With the new version it sounds like
you can debug/edit code on the fly similiar to an interpreted version
of C. I believe though that you require at least Solaris 2 for the new
version which has this feature.


Have a nice day,
