Hi, For reproducibility, package builds are run in a container without the network, so you can’t git clone inside it. This means you have to prevent it somehow, usually there are two cases: 1. CMake did not find a library and is trying to download and build it itself, in which case you need to make CMake find the library. 2. The build actually needs the source, in which case you can add the source to the inputs and unpack it and place it where expected as a build step. In the case of r2retdec, you can see in https://github.com/radareorg/r2retdec/blob/master/deps/retdec/CMakeLists.txt that it is trying to build it itself and also trying to build iaito. This is called in deps/CMakeLists.txt, in it you can see that by setting the BUILD_BUNDLED_RETDEC and BUILD_IAITO_PLUGIN to OFF it will not try to build them, but it will actually try to find them like normal libraries like in src/r2plugin/CMakeLists.txt. So, in summary. Add -DBUILD_BUNDLED_RETDEC=OFF and -DBUILD_IAITO_PLUGIN=OFF to your configure-flags and add those libraries as input. Does that make sense? Have a nice day, Noé
