http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46333 --- Comment #24 from Jonathan Wakely redi at gcc dot gnu.org --- (In reply to Sergey from comment #23) I'm still getting the same with sunpro building gcc 4.8.2 What do you mean the same? Are you using --enable-build-with-cxx for GCC 4.8.2? Are you using --disable-bootstrap with sunpro? If so, why? Are you using -library=stlport4? Just saying getting the same with no other information about what you're doing is not very helpful.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46333 --- Comment #25 from Sergey fukanchik at gmail dot com --- Sorry. I mean i am getting the following error: ../../gcc-4.5/libcpp/files.c, line 1193: Error: Cannot assign char* to int. this is obstack related stuff. The following does not compile: obstack_free (pfile-nonexistent_file_ob, 0); modifying it this way: obstack_free (pfile-nonexistent_file_ob, (void*)0); helps with compilation. Also happens in symtab.c, init.c, identifiers.c. And yes, i'm building cpp disable bootstrap if that counts.

Fix: #if (GCC_VERSION 2000) #define ENUM_BITFIELD(TYPE, NAME, SIZE) __extension__ enum TYPE NAME : SIZE #elif defined(__cplusplus) #define ENUM_BITFIELD(TYPE, NAME, SIZE) enum TYPE NAME #else #define ENUM_BITFIELD(TYPE, NAME, SIZE) unsigned int #endif Patch posted at: http://gcc.gnu.org/ml/gcc-patches/2011-08/msg00758.html some problem with obstack_free, I didn't investigate. Maybe substraction involving void* NULL or 0? Fix, obstack.h before: Before: # define obstack_free(h,obj)\ ( (h)-temp = (char *) (obj) - (char *) (h)-chunk,\ After, add cast to char*: # define obstack_free(h,obj)\ ( (h)-temp = (char *) ((char*)(obj)) - (char *) (h)-chunk,\ Bug in sunpro, reported and fixed in the development version (but possibly not for 12.3). There are also problems then compiling gmp in tree. I had to remove its #include iosfwd on Solaris because that pulled in locale and there was some problem. Maybe due to local hacks? I removed all the locale stuff from my gcc/gmp. CC is not a standard C++ compiler, you have to add -library=stlport4 to get it to even try. (In reply to comment #1) also lots of warnings about mixing extern C and not: Seems ok to ignore those that are only warnings. and other errors related, mixing said in ternary, like: foo = foo2 ? foo2 : foo3; (as in reallocator = set-reallocator ? set-reallocator : xrealloc) where foo2 and foo3 vary in extern C-ness. workaround is foo = foo2 if (!foo) foo = foo3 even though that doesn't seem different enough -- I understand there is the problem of figuring out a type for the ternary operator, but there is also the matter of being able to assign the function pointers This one is also Bug 50177. There is also Bug 50167. here's an example of the obtack_free problem, either I didn't get all the obstack.h files fixed or the cast needs to be void* or something: ../../gcc-4.5/libcpp/files.c, line 1193: Error: Cannot assign char* to int. Patch posted at: http://gcc.gnu.org/ml/gcc-patches/2011-08/msg00758.html (In reply to comment #7) rtl.c, change: #define DEF_RTL_EXPR(ENUM, NAME, FORMAT, CLASS) sizeof FORMAT - 1 , to: #define DEF_RTL_EXPR(ENUM, NAME, FORMAT, CLASS) sizeof (FORMAT) - 1 , seems to work.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46333 --- Comment #20 from joseph at codesourcery dot com joseph at codesourcery dot com 2010-11-08 13:12:11 UTC --- There really is absolutely no point experimenting with this option anywhere other than on trunk. Maybe we should just disable it on 4.5 branch; it's a GCC-developer-only option at this point. *Many* problems with C++ compatibility have been fixed on trunk since 4.5 branched. See Joern's work on fixing problems building different targets with --enable-werror-always (many of the problems fixed are C++ compatibility warnings). No such fixes will be backported to 4.5 branch. Since we're now in development stage 3, I expect that the default build will not be C++ until after 4.6 branches, which means that C++ fixes will not be backported to 4.6 branch either once that branch is created. Bug reports and fixes for such issues are only useful for trunk, and they are only useful when each separate problem (each problem with a genuinely different cause) is reported as a separate well-defined bug report; omnibus issues mixing different problems are useless, although meta-bugs marked as depending on the individual C++-compatibility bugs can be useful. As it happens we have such a bug: bug 44433. So when you have a well-defined issue verified to exist on trunk and to be distinct from all existing bugs, only then file a separate bug for that issue and mark it as blocking bug 44433.

In the discussions of what the requirements would be for building with C++, I think it was generally accepted that the answer would be the intersection of C++98 with what is supported by some baseline GCC version - and that at least 3.4, maybe 4.0 or 4.1, would be OK to take as that baseline. (PPL is a C++ library that won't build with versions older than 4.0, so anyone building a Graphite-enabled compiler is using a C++ compiler more recent than 3.4 already.) Yes, we should have a configure test that rules out known-too-old compilers. Another's g++ produces executables that don't run, can't find libstdc++. For build = host, a configure test for that may be useful as well. On that machine, I'm instead trying /usr/bin/CC which is SunStudio 12. If that supports C++98 at least as well as GCC 3.4 does, then it ought to work - and having people testing such things will be very useful for verifying that we aren't introducing accidental G++ dependencies when making C++ builds a requirement. You may be the first person testing non-G++ C++ builds.

This is all on Solaris 2.9, which may be out of support soon.
I can move to Solaris 2.10.
I need gcc 4.5.1. I can look into trunk *later*.
Some of my own patches run afoul of SunStudio 12 C++, that maybe
unique to me, e.g.:
bool unused_gcc_feature (...) { gcc_unreachable (); }
= unused_gcc_feature must return a value
so I put in return 0; unpatched gcc doesn't necessarily have this.
I'm not 100% which older g++ is on the other machine, just that it had problem
with attribute(unused). However, I bet it is easier to use than non-g++! :)
Also my ENUM_BITFIELD has an obvious typo in the last case, it need to
reference NAME.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46333 --- Comment #12 from Jay jay.krell at cornell dot edu 2010-11-07 01:37:15 UTC --- Huh, maybe enum bitfields are legal C++? #if defined(__cplusplus) #define ENUM_BITFIELD(TYPE, NAME, SIZE) enum TYPE NAME : SIZE seems to work, so can go back to the 1 parameter version, and not change gengtype. I will try it.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46333 --- Comment #13 from Jay jay.krell at cornell dot edu 2010-11-07 02:04:14 UTC --- gmpn_add/sub/cmp were because I have drastically slashed mpc/mpfr/gmp dependency, and optimizations off here. That is fixed. Now I can compile/link our cc1 analog! That's all we use. I can maybe continue this adventure with unpatched gmp/mpfr/mpc, trunk gcc, I'd limit myself to C and C++ frontends if I do. It could well be that without -disable-bootstrap, it doesn't use C++ until later stages and then works.

There are no references to it except for the macro, it appears. -bash-4.1$ CC -V CC: Sun C++ 5.9 SunOS_sparc 2007/05/03 -bash-4.1$ uname -a SunOS current10s 5.10 Generic_142909-17 sun4v sparc SUNW,SPARC-Enterprise-T5220
