I don't know why, but this is triggered by setting a custom toolchain (even an empty one): cmake -DCMAKE_TOOLCHAIN_FILE=/dev/null .
I ran into this and figured I should debug it a bit. Disclaimer: I don't know cmake. Cutting to the chase, the problem is probably this bit in kconfig-5.15.0/src/kconfig_compiler/CMakeLists.txt: if(CMAKE_TOOLCHAIN_FILE) if(BUILD_TESTING) message(WARNING "Testing should be disabled on cross-compilation") endif() else() add_executable(KF5::kconfig_compiler ALIAS kconfig_compiler) endif() I really should've grepped for CMAKE_TOOLCHAIN_FILE to begin with, I took the scenic route getting to that check. kconfig_compiler is a target with an OUTPUT_NAME of kconfig_compiler_kf5 (see right above that check). That's presumably why without CMAKE_TOOLCHAIN_FILE (with that add_executable()), the following gets generated: autotests/kconfig_compiler/signals_test_singleton.cpp: src/kconfig_compiler/kconfig_compiler_kf5 ... cd /tmp/kconfig-plain/autotests/kconfig_compiler && /tmp/kconfig-plain/src/kconfig_compiler/kconfig_compiler_kf5 /tmp/kconfig-5.15.0/autotests/kconfig_compiler/signals_test.kcfg /tmp/kconfig-5.15.0/autotests/kconfig_compiler/signals_test_singleton.kcfgc which works great, while with CMAKE_OUTPUT_FILE (without add_executable()), you get: autotests/kconfig_compiler/signals_test_singleton.cpp: /tmp/kconfig-5.15.0/autotests/kconfig_compiler/KF5::kconfig_compiler ... cd /tmp/kconfig-custom-toolchain/autotests/kconfig_compiler && KF5::kconfig_compiler /tmp/kconfig-5.15.0/autotests/kconfig_compiler/signals_test.kcfg /tmp/kconfig-5.15.0/autotests/kconfig_compiler/signals_test_singleton.kcfgc Notice the name of the kconfig compiler binary changed: it now has "::" in its name. Make's documentation for our error message points out why that name is a problem: "If you see these errors and you aren’t trying to create a static pattern rule, check the value of any variables in your target and prerequisite lists to be sure they do not contain colons". It's likely that CMakeLists.txt check could be improved to only skip the add_executable() bit if we're actually crosscompiling, but I don't know how. For now, I've just disabled testing as the build system wants me to.
(I meant: I disabled testing locally, no gentoo ebuilds were harmed)
Still broken in 5.16.0 and it's really annoying to kick off a massive kde update and come back later and find it barfed halfway through. Can you RESTRICT tests here?
Thanks for the report, and thanks Marien for the investigation. Tests are restricted for now until we are able to fix them. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=c803ee7f4cace1f0de12be5e7735f0cade312169 https://gitweb.gentoo.org/proj/kde.git/
