[gentoo-alpha] The use of compaq compilers ccc and cxx.

[Sigurd Stordal]

I've just loaded this compilers, and I just wonder if anyone else has used 
them, any packages that don't enjoy this compilers. Are they really very much 
better than gcc.

They really do generate better performing code than gcc, and most
packages can be built successfully. I wouldnt reccomend switching from
gcc to ccc for shared libraries (like zlib, openssl, etc) at the moment,
but most other things should work just great, and give a noticable
performance improvement (apache, python, bash, perl, etc).

cxx is a little more brittle than ccc, some code will make it dump core,
but ccc seems stable and gives very verbose and easy to read error
messages if something goes wrong, or it finds some code it doesnt like
(much nicer than gcc errors :).

the major problem with shared libraries is that applications compiled
with gcc that link with them require -lots, this can be solved by adding
libots to each library...i have some plans to work around this.

Have you tried to compile apache-2.0.48 with ccc? Does it work? If yes,
how did you manage it?
On a lot of packages (apache too) i get something like the following:

cc: Error: apr_snprintf.c, line 439: In this statement, "__LONG_MAX__"
is not declared. (undeclared)    if ((num <= ULONG_MAX && is_unsigned)
|| (num <= LONG_MAX && !is_unsigned))----------------^
cc: Error: apr_snprintf.c, line 695: In this statement, "__LONG_MAX__"
is not declared. (undeclared)    if (num <= ULONG_MAX)
---------------^
make[4]: *** [apr_snprintf.lo] Error 1
make[4]: *** Waiting for unfinished jobs....

Comments, suggestions, tips?

Thanks

Marc
