When emerging kodi 19.4 the build fails with the following error message (let me know if the full build log is needed): CMake Error at /usr/share/cmake/Modules/FindJava.cmake:171 (message): Error executing java -version Call Stack (most recent call first): xbmc/interfaces/swig/CMakeLists.txt:32 (find_package) 19.3-r1 worked just fine with same use flags. According to random forum post from 7 years ago, java is needed during bootstrap, but gentoo has previously used pre-bootstrapped code (?): https://forum.kodi.tv/showthread.php?tid=233523 Reproducible: Always Steps to Reproduce: 1. emerge media-tv/kodi-19.4 without java installed Actual Results: kodi fails to build Expected Results: kodi is built activated use flags: [ebuild U ~]

Java is required and is expressed correctly as a DEPENDS dependency. It seems you don't have Java correctly installed. What happens when you run: * java -version * java-config -L In any case, this issue isn't a problem with Kodi - it's a problem with the Java installation on your system.
aah, sorry I guess I should have checked that; You're absolutely correct. I was confused because a jre was not installed, and was not installed by emerge -uDN, but I forgot to check if jdk was installed (which it obviously was). The problem was that the system java vm was pointing to an old version that had been uninstalled. I guess for some reason portage didn't change the system java vm when upgrading from java 8 to 11. 'eselect java-vm set system 1' fixed the problem. Sorry for the noise!
