In this post, I will describe building cross-platform C++ applications for macOS on an Ubuntu build machine using CMake and osxcross.
\nFirst, install the osxcross toolchain:
\nhttps:\/\/github.com\/tpoechtrager\/osxcross<\/a>
\nInstallation occurs in 3 stages, downloading dependencies:<\/p>\n

\n
cd tools\n.\/get_dependencies.sh\n<\/code><\/pre>\n<\/div>\n
Download XCode.xip from the official Apple website, then download the SDK from XCode:<\/p>\n
\n
.\/gen_sdk_package_pbzx.sh \/media\/demensdeum\/2CE62A79E62A4404\/LinuxSupportStorage\/xcode111.xip\n<\/code><\/pre>\n<\/div>\n
I hope you read the XCode license agreement in the last step? Next, build the toolchain with the required prefix:<\/p>\n
\n
INSTALLPREFIX=\/home\/demensdeum\/Apps\/osxcross .\/build.sh \n<\/code><\/pre>\n<\/div>\n
Now you can use osxcross from the prefix directory of the previous step. Let’s add a new build macro for CMake and write everything necessary:<\/p>\n
\n
if (OSXCROSS)\nSET(CMAKE_SYSTEM_NAME Darwin)\nSET(CMAKE_C_COMPILER o64-clang)\nSET(CMAKE_CXX_COMPILER o64-clang++)\nSET(CMAKE_C_COMPILER_AR x86_64-apple-darwin19-ar)\nSET(CMAKE_CXX_COMPILER_AR x86_64-apple-darwin19-ar)\nSET(CMAKE_LINKER x86_64-apple-darwin19-ld)\nSET(ENV{OSXCROSS_MP_INC} 1)\nendif()\n<\/code><\/pre>\n<\/div>\n
Dynamic linking was not successful for me, so we export the libraries statically:<\/p>\n
\n
if (OSXCROSS)\nadd_library(FlameSteelCore STATIC ${SOURCE_FILES})\nelse()\n<\/code><\/pre>\n<\/div>\n
Next, you may be faced with the fact that you do not have the necessary libraries for osxcross, I encountered this when using SDL2. osxcross supports ready-made library packages – macports. For example, installing SDL2-mixer:<\/p>\n
\n
osxcross-macports -v install libsdl2_mixer\n<\/code><\/pre>\n<\/div>\n
After this, you can start building libraries\/applications as usual in the cmake-make link, do not forget to specify static linking of libraries if necessary.<\/p>\n
Manual assembly of libraries<\/h3>\n
Currently, I have encountered the problem of incorrect archiving of libraries during static linking; when building the final application I receive the error:<\/p>\n
\n
file was built for archive which is not the architecture being linked (x86_64)\n<\/code><\/pre>\n<\/div>\n
Very similar to this ticket<\/a>, we managed to implement a workaround resulting in the build completing correctly. Let’s unzip the static library and build it anew using the osxcross archiver:<\/p>\n
\n
ar x ..\/libFlameSteelCore.a\nrm ..\/libFlameSteelCore.a\nx86_64-apple-darwin19-ar rcs ..\/libFlameSteelCore.a *.o\n<\/code><\/pre>\n<\/div>\n
Also, one of the problems I personally consider is the lack of ability to run macOS applications directly on Ubuntu (at least with part of the functionality). Of course, there is a project darling<\/a>, but the support still leaves much to be desired.<\/p>\n
