Hi, I’ve got an unusual problem. I have on old DECstation (MIPS R3000 based) running the infamous OSF/1. I got gcc-2.7.2.3 compiled and working and I am now trying to upgrade to 3.0.4. One problem I found is that gcc-3.0.4 no longer defines #define __LANGUAGE_C__ 1 and a number of header files depend on it. It still defines #define __LANGUAGE_C 1 but of course that is not the same. gcc-2.7.2.3 still defined it correctly. I assume that this is just an error in some file, but I can’t find where these defines are set. this is what gcc-2.7.2.3 sets: # gcc -v Reading specs from /usr/local/lib/gcc-lib/mips-dec-osf/2.7.2.3/specs gcc version 2.7.2.3 # gcc -dM -E - < /dev/null #define __LANGUAGE_C 1 #define R3000 1 #define __SYSTYPE_BSD__ 1 #define SYSTYPE_BSD 1 #define __host_mips 1 #define __MIPSEL__ 1 #define __ANSI_COMPAT 1 #define __MIPSEL 1 #define __mips__ 1 #define __mips 1 #define __host_mips__ 1 #define __osf 1 #define __GNUC_MINOR__ 7 #define MIPSEL 1 #define __R3000__ 1 #define __PTRDIFF_TYPE__ int #define host_mips 1 #define __SYSTYPE_BSD 1 #define mips 1 #define __LANGUAGE_C__ 1 #define __unix 1 #define osf 1 #define __osf__ 1 #define __R3000 1 #define __unix__ 1 #define __bsd4_2 1 #define __bsd4_2__ 1 #define __GNUC__ 2 #define LANGUAGE_C 1 #define _SYSTYPE_BSD 1 #define bsd4_2 1 #define unix 1 this is what the new stage1 gcc-3.0.4 sets: # stage1/xgcc -Bstage1/ -B/usr/local/mips-dec-osf1/bin/ -c -DIN_GCC -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -DHAVE_CONFIG_H -I. -Icp -I../../gcc-3.0.4/gcc -I../../gcc-3.0.4/gcc/cp -I../../gcc-3.0.4/gcc/config -I../../gcc-3.0.4/gcc/../include -dM -E - < /dev/null #define __USER_LABEL_PREFIX__ #define __host_mips 1 #define HAVE_CONFIG_H 1 #define __SYSTYPE_BSD 1 #define __R3000__ 1 #define __osf 1 #define __PTRDIFF_TYPE__ int #define bsd4_2 1 #define __HAVE_BUILTIN_SETJMP__ 1 #define MIPSEL 1 #define __host_mips__ 1 #define __GNUC_PATCHLEVEL__ 4 #define __mips 1 #define __WCHAR_TYPE__ short unsigned int #define __osf__ 1 #define LANGUAGE_C 1 #define __MIPSEL__ 1 #define __R3000 1 #define __GNUC_MINOR__ 0 #define osf 1 #define __WINT_TYPE__ unsigned int #define IN_GCC 1 #define __SYSTYPE_BSD__ 1 #define __ANSI_COMPAT 1 #define SYSTYPE_BSD 1 #define __unix 1 #define unix 1 #define __mips__ 1 #define __LANGUAGE_C 1 #define R3000 1 #define __bsd4_2 1 #define __OPTIMIZE__ 1 #define __MIPSEL 1 #define __REGISTER_PREFIX__ #define __GNUC__ 3 #define __bsd4_2_ 1 #define _LANGUAGE_C 1 #define __VERSION__ "3.0.4" #define mips 1 #define _SYSTYPE_BSD 1 #define __STDC_HOSTED__ 1 #define host_mips 1 #define __unix__ 1 #define __STDC__ 1 thanks, Dennis
