Dear seL4 devs and community.
I try to create a simple project using the seL4 micro kernel. For setting up my environment I followed this (https://github.com/manu88/SeL4_101) and this (https://docs.sel4.systems/projects/buildsystem/incorporating.html) article. As kernel I'm using the last release of SeL4 (https://github.com/seL4/seL4/releases/tag/12.1.0). I created some kind of user application, like Manu88 did with a simple Hello World C-Program. While building with the delivered init-build.sh script I got a lot of repeating errors like this: CMake Error at tools/cmake-tool/helpers/simulation.cmake:179 (add_custom_command): Error evaluating generator expression:
$
Target "rootserver_image" not found. Call Stack (most recent call first): CMakeLists.txt:22 (GenerateSimulateScript) While going through Manu88s guide I saw that he also got this errors. But after adding a CMakeList.txt file inside his user code, and declaring it as rootserver inside the CMakeList.txt file (I just copied the contents from here: https://github.com/manu88/SeL4_101/blob/master/projects/Hello/CMakeLists.txt) he got rid of the errors. I still get them and searching through the internet could not find a solution for me. Bellow I added the folder structure of my project. Project/ ├── kernel/ ├── projects/ │ ├── Hello/ │ ├── musllibc/ │ ├── utils_libs/ │ ├── seL4_libs/ ├── build/ ├── tools/ │ └── cmake-tool/ │ └── elfloader-tool/ ├── init-build.sh -> tools/cmake-tool/init-build.sh ├── CMakeLists.txt ├── application_settings.cmake -> tools/cmake-tool/helpers/application_settings.cmake ├── settings.cmake
So I cannot tell where the issue lies. Any pointers would be appreciated.
If you are using https://github.com/manu88/SeL4_101/blob/master/projects/Hello/CMakeLists.txt inside projects/Hello/ then you need to make sure that the top level CMakeLists inside Project/ is either a symlink to tools/cmake-tool/default-CMakeLists.txt or is similar to https://github.com/manu88/SeL4_101/blob/master/CMakeLists.txt. With this file layout, ../init-build.sh will end up calling the following CMake invocation: `cmake -DCMAKE_TOOLCHAIN_FILE=../kernel/gcc.cmake -G Ninja -DSEL4_CACHE_DIR=../.sel4_cache -C "../settings.cmake" "../"`. What is the contents of your settings.cmake file?
