Hi, When i install the gcc 3.0.2, I try to compile a simple c++ program,but get error like this: /usr/ccs/bin/as: "/var/tmp/ccmqRkgN.s", line 6472: error: statement syntax /usr/ccs/bin/as: "/var/tmp/ccmqRkgN.s", line 6477: error: unknown opcode ".uleb128" /usr/ccs/bin/as: "/var/tmp/ccmqRkgN.s", line 6477: error: statement syntax /usr/ccs/bin/as: "/var/tmp/ccmqRkgN.s", line 6480: error: unknown opcode ".uleb128" /usr/ccs/bin/as: "/var/tmp/ccmqRkgN.s", line 6480: error: statement syntax /usr/ccs/bin/as: "/var/tmp/ccmqRkgN.s", line 6481: error: unknown opcode ".uleb128" /usr/ccs/bin/as: "/var/tmp/ccmqRkgN.s", line 6481: error: statement syntax But when i compile with the c program, it is ok. I do not know why, any help will be appreciated. the c++ program , #include <iostream.h> main () { cout << "Helo world" << endl; } the c program #include <stdio.h> int main(int argc, char *argv[]) { printf("Hello, world\n"); return 0; }
