[SuSE 8.2] gcc 3.3.1-0 update leads to compile errors in glibc-devel files
Hi there! Today I upgraded my gcc to 3.3.1-0 using the newly provided SuSE rpms. These are the updated rpms: gcc-c++-3.3.1-0.i586.rpm gnat-3.3.1-0.i586.rpm libobjc-3.3.1-0.i586.rpm gcc-g77-3.3.1-0.i586.rpm gnat-runtime-3.3.1-0.i586.rpm libstdc++-3.3.1-0.i586.rpm cpp-3.3.1-0.i586.rpm gcc-info-3.3.1-0.i586.rpm libgcc-3.3.1-0.i586.rpm libstdc++-devel-3.3.1-0.i586.rpm gcc-3.3.1-0.i586.rpm gcc-java-3.3.1-0.i586.rpm libgcj-3.3.1-0.i586.rpm gcc-3.3.1-0.src.rpm gcc-objc-3.3.1-0.i586.rpm libgcj-devel-3.3.1-0.i586.rpm However, some programs do not compile anymore (in this case kdemultimedia) because of errors in a glibc-devel file: Compiling kdemultimedia CVS: In file included from /usr/include/linux/byteorder/little_endian.h:11, from /usr/include/asm/byteorder.h:32, from /usr/include/linux/cdrom.h:14, from cdromAccess_Linux.cpp:17, from cdromAccess.cpp:30: /usr/include/linux/byteorder/swab.h: In function `const __u32 __fswab24(unsigned int)': /usr/include/linux/byteorder/swab.h:174: error: ISO C++ forbids braced-groups within expressions /usr/include/linux/byteorder/swab.h:174: error: ISO C++ forbids braced-groups within expressions /usr/include/linux/byteorder/swab.h: In function `__u32 __swab24p(__u32*)': /usr/include/linux/byteorder/swab.h:178: error: ISO C++ forbids braced-groups within expressions /usr/include/linux/byteorder/swab.h:178: error: ISO C++ forbids braced-groups within expressions /usr/include/linux/byteorder/swab.h: In function `void __swab24s(__u32*)': /usr/include/linux/byteorder/swab.h:182: error: ISO C++ forbids braced-groups within expressions /usr/include/linux/byteorder/swab.h:182: error: ISO C++ forbids braced-groups within expressions make[4]: *** [cdromAccess.lo] Fehler 1 I didn't find an up-to-date SuSE rpm for glibc and glibc-devel.

However, some programs do not compile anymore (in this case kdemultimedia) because of errors in a glibc-devel file:
Compiling kdemultimedia CVS: In file included from /usr/include/linux/byteorder/little_endian.h:11, from /usr/include/asm/byteorder.h:32, from /usr/include/linux/cdrom.h:14, from cdromAccess_Linux.cpp:17, from cdromAccess.cpp:30: /usr/include/linux/byteorder/swab.h: In function `const __u32 __fswab24(unsigned int)': /usr/include/linux/byteorder/swab.h:174: error: ISO C++ forbids braced-groups within expressions
For the time being try editing the file yourself. First make a backup copy of the file. Then change these macros #define ___swab16(x) \ ({ \ __u16 __x = (x); \ ((__u16)( \ (((__u16)(__x) & (__u16)0x00ffU) << 8) | \ (((__u16)(__x) & (__u16)0xff00U) >> 8) )); \ }) So they look like this: #define ___swab16(x) \ (__extension__{ \ __u16 __x = (x); \ ((__u16)( \ (((__u16)(__x) & (__u16)0x00ffU) << 8) | \ (((__u16)(__x) & (__u16)0xff00U) >> 8) )); \ }) i.e. add __extension__ before the braced group. This should do the trick. I'll talk with my colleague whether or not to put a modified glibc-devel in /pub/projects/gcc/8.2 sometime next week. In the future *please* report things like this at http://www.suse.de/feedback as I clearly stated in the READMEs (if you haven't already done so)! Otherwise chances are very high that we'll never notice it. Philipp

So they look like this:
#define ___swab16(x) \ (__extension__{ \ __u16 __x = (x); \ ((__u16)( \ (((__u16)(__x) & (__u16)0x00ffU) << 8) | \ (((__u16)(__x) & (__u16)0xff00U) >> 8) )); \ })
i.e. add __extension__ before the braced group. This should do the trick.
OK, I added __extension__ to those macros but it still doesn't work; here is what I get: /usr/include/linux/byteorder/swab.h: In function `const __u32 __fswab24(unsigned int)': /usr/include/linux/byteorder/swab.h:174: error: ISO C++ forbids braced-groups within expressions /usr/include/linux/byteorder/swab.h:174: error: parse error before `{' token /usr/include/linux/byteorder/swab.h:174: error: `__x' undeclared (first use this function) /usr/include/linux/byteorder/swab.h:174: error: (Each undeclared identifier is reported only once for each function it appears in.) /usr/include/linux/byteorder/swab.h: At global scope: /usr/include/linux/byteorder/swab.h:174: error: parse error before `)' token /usr/include/linux/byteorder/swab.h: In function `__u32 __swab24p(__u32*)': /usr/include/linux/byteorder/swab.h:178: error: parse error before `{' token /usr/include/linux/byteorder/swab.h: At global scope: /usr/include/linux/byteorder/swab.h:178: error: parse error before `)' token /usr/include/linux/byteorder/swab.h: In function `void __swab24s(__u32*)': /usr/include/linux/byteorder/swab.h:182: error: parse error before `{' token /usr/include/linux/byteorder/swab.h:182: error: parse error before `)' token

In the future *please* report things like this at http://www.suse.de/feedback as I clearly stated in the READMEs (if you haven't already done so)! Otherwise chances are very high that we'll never notice it. I'll remember that, thanks for pointing me there ;-)

OK, second try. Could you please post *all* options that are passed to gcc? Philipp -- Philipp Thomas work: pthomas@suse.de private: philipp.thomas@t-link.de

As I thought :) Remove -pedantic and -ansi from the compiler flags (probably CXXFLAGS in the Makefile). That should turn the errors into warnings and let it continue to compile. Philipp
