The problem appears to be that gcc 3.3.2 seems to use a builtin define __INT_MAX__ which ccc does not understand. This causes ccc to fail when compiling xemacs (the only way I have found to get a stable xemacs on gentoo alpha is to use ccc). A quick google search revealed this link: * http://gcc.gnu.org/ml/gcc-patches/2002-06/msg01087.html ... which may be helpful. Reproducible: Always Steps to Reproduce: 1. CC=ccc emerge xemacs 2. 3.

I was able to compile xemacs by adding the following to my comp.config file: "-D__SCHAR_MAX__=127 -D__SHRT_MAX__=32767 -D__INT_MAX__=2147483647 -D__LONG_MAX__=9223372036854775807 -D__LONG_LONG_MAX=9223372036854775807 -D__CHAR_BIT__=8 -D__DBL_DIG__=15"
I am guessing that the problem is that xemacs does not include limits.h where it should. When GCC is used, limits.h probably gets included inadvertantly, and so the problem is not noticed. When I have more time, I will actually check the code. Until then, you could check yourself to see if this is the case.
Did you have success adding the limits.h somewhere in the build definitions of the package? If yes, can we get this out of sight for our gcc bug hunters ;-) Alex
No, this does not fix the problem. Explanation follows: With the latest ccc ebuild installed (6.5.9.001-r3) I get the following error when building xemacs: *** ccc -c -arch ev67 -O3 -Demacs -I. -DHAVE_CONFIG_H -std1 -I/usr/X11R6/include print.c cc: Error: print.c, line 915: In this statement, "__DBL_DIG__" is not declared. (undeclared) if (width < (int) (*cp != 'e' && *cp != 'E') || width > DBL_DIG) --------------------------------------------------------------^ make[1]: *** [print.o] Error 1 make[1]: Leaving directory `/var/tmp/portage/xemacs-21.4.12/work/xemacs-21.4.12/src' make: *** [src] Error 2 !!! ERROR: app-editors/xemacs-21.4.12 failed. !!! Function src_compile, Line 170, Exitcode 2 !!! (no error message) *** As you can see from the error message, the problem is with "__DBL_DIG__" missing from the include files (it is not defined). A quick google revealed that in the later versions of gcc the basic constants such as "INT_MAX" and "DBL_DIG" have been #defined to double underscore versions. For example take a look at line 57 from the float.h file for gcc-3.3.3 which on my system is located here: * /usr/lib/gcc-lib/alphaev67-unknown-linux-gnu/3.3.3/include The file has the followin on line 57: #define DBL_DIG __DBL_DIG__ And if look at the link in my original problem report you can see that the later versions of gcc changed to the double underscore. This is why my original workaround of modifing the comp.config file worked. This is not a problem with xemacs but rather a problem with ccc and the latest versions of gcc as originally stated.
And you are right and this is therefore an upstream bug and i am closing it now. see http://gcc.gnu.org/bugs.html for filing. Alex
