#41020: undefined symbol for toupper(int) when compiled as C11 ------------------------+-------------------------------- Reporter: davydden@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.1 Keywords: | Port: gcc ------------------------+-------------------------------- The simple example which uses toupper(int) {{{ #include <stdio.h> #include <ctype.h> int main () { int i=0; char str[]="Test String.\n"; char c; while (str[i]) { c=str[i]; putchar (toupper(c)); i++; } return 0; } }}} does link via {{{ g++-mp-4.8 main.cc -o main }}} but does not when invoking C11: {{{ g++-mp-4.8 -std=c++11 main.cc -o main Undefined symbols for architecture x86_64: "toupper(int)", referenced from: _main in ccWjHauc.o ld: symbol(s) not found for architecture x86_64 collect2: error: ld returned 1 exit status }}} Macports was build on Xcode 5 under 10.9. I am not sure if this is related to gcc4.8, but this behavior was not the case for the previous Xcode (4.6) and OS-X Mountain Lion. -- Ticket URL: <https://trac.macports.org/ticket/41020> MacPorts <http://www.macports.org/> Ports system for OS X
