I did some digging and it seems all of these failures are related. Each of them is adding the host path /usr/include somewhere which should not be the case when cross compiling. GCC even detects this and issues warnings: cc1: warning: include location "/usr/include" is unsafe for cross-compilation [-Wpoison-system-directories] CMake has some magic inside that removes "implicit include" paths. By default this is set to "/urs/include" as this makes sense when doing non cross compilation. Setting CMAKE_SYSROOT changes this as the "implicit include" paths are now re rooted to CMAKE_SYSROOT. This leads to CMake no longer considering /usr/include a special path and thus it is no longer removed. In my opinion this is an issue with the recipes that failed. I already found how to fix it for wireshark and I will try to fix the others too, then I will send an updated patchset.
