The following issue has been SUBMITTED. ====================================================================== http://public.kitware.com/Bug/view.php?id=14768 ====================================================================== Reported By: Paul Smith Assigned To: ====================================================================== Project: CMake Issue ID: 14768 Category: CMake Reproducibility: always Severity: major Priority: high Status: new ====================================================================== Date Submitted: 2014-02-20 15:48 EST Last Modified: 2014-02-20 15:48 EST ====================================================================== Summary: Using OBJECT libraries with Xcode causes incorrect builds Description: I wanted to use an OBJECT library in order to build both a static and shared library from the same set of objects, across multiple directories. This works great with Makefiles and Visual Studio but fails with Xcode: the initial build works fine but if I then change a file and re-run the build it compiles the object file but does NOT update the libraries and executables that depend on it.
Steps to Reproduce: CMakeLists.txt: #---------- cmake_minimum_required(VERSION 2.8.12) project(CMTEST CXX) add_library(foo_OBJECTS OBJECT foo.cpp foo.h) add_library(foo SHARED dummy.cpp $<TARGET_OBJECTS:foo_OBJECTS>) add_dependencies(foo foo_OBJECTS) add_executable(hello hello.cpp) target_link_libraries(hello foo) #---------- Then create a trivial foo.cpp, foo.h, and hello.cpp. Run "cmake -G Xcode ." Run "xcodebuild build -configuration RelWithDebInfo" (or use "cmake -build" if you prefer). All builds and is fine. Now modify foo.cpp. Run "xcodebuild build -configuration RelWithDebInfo" again (or "cmake -build") Note that Xcode recompiles foo.o and updates libfoo_OBJECTS.a, _BUT_ it does NOT recreate libfoo.a and it does not re-link the hello program. Additional Information: I've tried this with Xcode 4.6 and Xcode 5.0. I've tried it with CMake 2.8.12.2 and also with the latest CMake 3.0.0-rc1 from Git master; same behavior in all situations. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2014-02-20 15:48 Paul Smith New Issue ====================================================================== -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
