I am trying to build GCC 3.0 on my suse 10.1 machine that has gcc 4.1.0. I need it to check backwards compatibility with some readers I have written. Is is crashing on me: gcc -I../../gcc-3.0/gcc/cp -I../../gcc-3.0/gcc/config -I../../gcc-3.0/gcc/../include ../../gcc-3.0/gcc/cp/decl.c -o cp/decl.o ../../gcc-3.0/gcc/cp/decl.c: In function ‘push_binding_level’: ../../gcc-3.0/gcc/cp/decl.c:528: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c: In function ‘pop_binding_level’: ../../gcc-3.0/gcc/cp/decl.c:584: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c: In function ‘suspend_binding_level’: ../../gcc-3.0/gcc/cp/decl.c:599: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c:621: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c: In function ‘resume_binding_level’: ../../gcc-3.0/gcc/cp/decl.c:634: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c: In function ‘pushdecl_with_scope’: ../../gcc-3.0/gcc/cp/decl.c:4294: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c:4296: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c: In function ‘init_decl_processing’: ../../gcc-3.0/gcc/cp/decl.c:6405: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c: In function ‘grokdeclarator’: ../../gcc-3.0/gcc/cp/decl.c:9932: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c:9935: error: invalid lvalue in assignment ../../gcc-3.0/gcc/cp/decl.c: In function ‘start_function’: ../../gcc-3.0/gcc/cp/decl.c:13472: error: invalid lvalue in assignment make[1]: *** [cp/decl.o] Error 1 make[1]: Leaving directory `/root/applications/gcc-3.0-build/gcc' make: *** [all-gcc] Error 2 Can anyone provide assistance?
