HI, I have tried to build gdc with gcc 4.2.2 . I know it is not support yet.I just want to have a try. Then the problem is : when build the d-lang.glue.o , there are some errors in d-codegen.h there is a function named 'build'. I can't find the declaration of it, of course the same to the compiler. there are also functions named 'build1' 'build2' 'build3' . and the declaration of them are also missed. Doesn't it strange? If the same code can work around gcc 4.1, what was happend? How can gcc 4.1 find the functions? where are they? anybody give me a hand? thank you!

There are also in ChangeLog-2003: 2003-05-17 Kaveh R. Ghazi <ghazi caip.rutgers.edu> * builtins.c (validate_arglist): Eliminate libiberty VA_ macros, always use stdarg. [...] * tree.c (build, build_nt, build_function_type_list): Likewise. Please let us know if you get something working, it would be so nice if gdc were ported to gcc-4.2. :-) Have a nice day, Arthur.

Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I've been able to build gdc with gcc-4.2, it stills segfault sometimes and is unable to build phobos/tango for now, but it's a beginning and can compile short D files. I've put the patches in: http://people.dunnewind.net/arthur/gdc-4.2/patches/ gdc-4.2-build.dpatch updates gcc/d/Make-lang.in for the new gcc-4.2 objs (pr26885) and gcc/d/d-builtins.c copied from the new c-common.c. gdc-4.2.dpatch is mostly taked from patch-gcc-4.1.x, adding this: --- gcc/tree.h 2007-11-15 14:21:01.000000000 +0100 +++ gcc/tree.h 2007-11-15 14:22:05.000000000 +0100 -3535,6 +3535,19 =20 extern tree build_nt (enum tree_code, ...); =20 +/* Still required by gdc */ +#if GCC_VERSION >=3D 3000 || __STDC_VERSION__ >=3D 199901L +/* Use preprocessor trickery to map "build" to "buildN" where N is the + expected number of arguments.

Any help would be welcome, there is still a lot of work to get it working. :-) Arthur.

Hi Arthur, nice to see that happening!

David, would you accept a patch from me, which does ONLY that?I'm currently trying to fix ICEs, the problems seems to come from gimple.Yes, I have seen the same and my vacation was over, so I stopped it. I have some questions for some parts of that patch. I'll mail them to you. Best Regards Ingo Oeser
