I tested cross-compile CMake 3.16.x and 3.20.5 on Ubuntu 20.04 and with original configuration as above, findpackage(Curses) won't be able to find the library. BOOTSTRAP_LLVM_ENABLE_LLD can be used to add lld to the dependency list, but since I'm setting CLANG_DEFAULT_LINKER=llb, I don't want clang adding -fuse-ld.ĭid a quick test and setting BOOTSTRAP_CMAKE_TOOLCHAIN_FILE does not work in this case. It's also worth to take a look at CMAKEFINDROOTPATHMODEPROGRAM in which as per CMake documentation, setting to NEVER wouldn't search for library in what set in CMAKEFINDROOTPATH. When running ninja stage2, I need to insure that the dependancies where built. While I'm happy to use BOOTSTRAP_CMAKE_TOOLCHAIN_FILE instead of passing -DCMAKE_TOOLCHAIN_FILE=$, I do not see how it helps with this problem. The AWS SDK for C++ includes a CMake toolchain file that includes what you. CMAKE LINUX TO MAC TOOLCHAIN FILE INSTALLUnless there's another way to do it, It's not hacky. To install the packages on Amazon Linux/Redhat/Fedora/CentOS-based systems. That avoids the need for the ADDITIONAL_CLANG_BOOTSTRAP_DEPS variable, which feels a bit hacky to me. Splitting this into two files won't make much difference in that regard.įor bootstrap builds where you want the stage1 to run on your build host, you should be able to set BOOTSTRAP_CMAKE_TOOLCHAIN_FILE in the first stage build, to signal to the first stage build that the second stage will be cross-compiled, and we can customize the multi-stage dependencies correctly based on that. We built the embedded Linux system with Yocto. I used Yocto Morty and CMake v3.5.1 (as it comes with Ubuntu 16.04 LTS). I am going to give a line-line by line explanation of the CMake toolchain file. As we use CMake for building our Qt application, we must create a CMake toolchain file. if(MSVC) is a compiler check and not a host/target system check. The if part of the if/else is used in stage1 as a cache file, and the else part used in stage2 (and as you said, is loaded many times). Next, we want to cross-compile our own Qt application. you want to define CMAKETOOLCHAINFILE and VCPKGTARGETTRIPLET before your project(ExtractOnctData)call (so the third example will never work) You want to use if(WIN32) (target system) or if(CMAKEHOSTWIN32) instead of if(MSVC). I really like keeping this in a single file, but will break it up if necessary. That is the correct way this build should work. As pointed out we absolutly want the behavior of the toolchain file being loaded multiple times. This issue occurs with CMake 3.22.You should split the CMake cache file you created into two files, (1) a CMake Cache to manage the build configuration and (2) a tool chain file for targeting Linux. It fails with the following output: Change Dir: /Users/arthur/CLionProjects/test/cmake-build-debug-msp432/CMakeFiles/CMakeTmp Run Build Command(s):/usr/bin/make -f Makefile cmTC_8747d/fast & /Library/Developer/CommandLineTools/usr/bin/make -f CMakeFiles/cmTC_8747d.dir/build.make CMakeFiles/cmTC_8747d.dir/build Building C object CMakeFiles/cmTC_8747d.dir/testCCompiler.c.o /opt/homebrew/bin/arm-none-eabi-gcc -arch arm64 -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk -o CMakeFiles/cmTC_8747d.dir/testCCompiler.c.o -c /Users/arthur/CLionProjects/test/cmake-build-debug-msp432/CMakeFiles/CMakeTmp/testCCompiler.c arm-none-eabi-gcc: error: arm64: No such file or directory arm-none-eabi-gcc: error: unrecognized command-line option '-arch' did you mean '-march='? make: *** Error 1 make: *** Error 2 CMake will not be able to correctly generate this project. system called Pacman, which should be familiar to Arch Linux users.
