I built an extremely simple project. Contains main.cpp, and then a library with widget.cpp init. here is the CMakeLists.txt that I'm using
project( c++_cmd_line ) CMAKE_MINIMUM_REQUIRED(VERSION 2.6) #setup the output directories set( LIB_OUT_DIR ${CMAKE_BINARY_DIR}/bin/lib ) set( EXE_OUT_DIR ${CMAKE_BINARY_DIR}/bin ) set( EXECUTABLE_OUTPUT_PATH ${EXE_OUT_DIR} ) set( LIBRARY_OUTPUT_PATH ${LIB_OUT_DIR} ) add_library( widget STATIC widget.h widget.cpp ) add_executable( c++_cmd_line main.cpp ) add_dependencies( c++_cmd_line widget ) main.cpp is just Hello world that calls a couple made up functions in the widget class to get the dependencies. And here is what the make spits out Scanning dependencies of target widget [ 50%] Building CXX object CMakeFiles/widget.dir/widget.cpp.o Linking CXX static library bin/lib/libwidget.a [ 50%] Built target widget Scanning dependencies of target c++_cmd_line [100%] Building CXX object CMakeFiles/c++_cmd_line.dir/main.cpp.o Linking CXX executable bin/c++_cmd_line Undefined symbols: "Widget::get_i()", referenced from: _main in main.cpp.o "Widget::get_j()", referenced from: _main in main.cpp.o "Widget::Widget()", referenced from: _main in main.cpp.o ld: symbol(s) not found collect2: ld returned 1 exit status make[2]: *** [bin/c++_cmd_line] Error 1 make[1]: *** [CMakeFiles/c++_cmd_line.dir/all] Error 2 make: *** [all] Error 2 I've tried moving the build directory around and even running cmake directly in my source directory, but to no avail. -Neal On Fri, Nov 14, 2008 at 5:16 AM, Michael Jackson < [EMAIL PROTECTED]> wrote: > > On Nov 13, 2008, at 7:59 PM, Neal Meyer wrote: > > I have a project that I have been working on for a while using the Visual >> Studio generator in Windows, and I am now attempting to build in on Mac. >> Right now it's very early and I'm having problems building any of the >> executables using the Unix Makefile generation or the XCode generator.
