Hi Alexander Here is how I made the patch: cd ~ mkdir -pv freebsd cd freebsd cvs -d [EMAIL PROTECTED]:/home/ncvs co -rRELENG_7 src cvs diff -rFSF FreeBSD-gcc-4.2.1.patch I have applied the patch on a fresh copy of gcc-4.2.1 and compiled. As before it develops errors: ../../gcc-4.2.1/gcc/c-format.c: In function 'check_format_info_main': ../../gcc-4.2.1/gcc/c-format.c:1780: error: 'flag_format_extensions' undeclared (first use in this function) ../../gcc-4.2.1/gcc/c-format.c:1780: error: (Each undeclared identifier is reported only once ../../gcc-4.2.1/gcc/c-format.c:1780: error: for each function it appears in.) gmake[2]: *** [c-format.o] Error 1 Have I missed out something? Could you help me to move forward from here? For an example, I can over come the above error by adding following lines to the gcc-4.2.1/gcc/config/i386/i386.opt: fformat-extensions Common Report Var(flag_format_extensions) Init(0) Allow FreeBSD kernel-specific printf format specifiers. Is that the correct move forward?

Hi Alexander, thanks for the reply. I'm new to 'cvs diff -rFSF'. I need to do more home work before I try your method. Could you kindly confirm it work for you? after applying the patch, does your compilation of gcc complete cleanly? I get errors. Therefore, could you try it please. I'm waiting for your reply. Best regards Unga I never had a good reason to try, but it should compile with little or no extra work. Getting diff against vendor branch in CVS is much easier way than what you are doing anyway. -- Alexander Kabaev signature.asc Description: PGP signature
