I recently installed Fedora Core 3 and tried to compile the grub package for L4 using gcc 3.4.2, I got some trivial compilation errors. Upon trying the compilation on different machine with gcc 3.1 I found some code following deprecated practices that escapes as warnings in < 3.4.2 but throws compilation errors with 3.4.2. Here are three such case I found in the grub package. If this is indeed the case it might be helpful to make the necessary changes to the repository code. ------------------------------------------------------------------------ ------------------------------------------------------------------ 1) stage2/builtins.c for gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3): builtins.c:886: error: missing terminating " character builtins.c:887: error: `Version' undeclared (first use in this function) builtins.c:887: error: (Each undeclared identifier is reported only once builtins.c:887: error: for each function it appears in.) builtins.c:887: error: syntax error before ':' token builtins.c:887:20: invalid suffix "x" on integer constant for gcc version 3.1: builtins.c:886:20: warning: multi-line string literals are deprecated 2)stage2/fsys_reiserfs.c for gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3): typedef unsigned int __u32; __u32 long j_mount_id; gives this error: fsys_reiserfs.c:115: error: long, short, signed or unsigned used invalidly for `j_mount_id' gcc version 3.1:allows it 3)stage2/smp-imps.c For switch-case construct: switch(i){ Case 1: break; ... Default: } 3.1 gives: warning: deprecated use of label at end of compound statement 3.4.2 will not allow this: smp-imps.c:437: error: label at end of compound statement ------------------------------------------------------------------------ ------------------------------------------------------------------ After changing the files and getting over the compilation errors I get some linking errors.
