Created attachment 7101 [details] add missing -ldl to lua.pc When I updated my existing buildroot configuration to 2017.05 or newer I get build errors in the package "swupdate": Trying libraries: pthread lua m z ubootenv Failed: -Wl,--start-group -lpthread -llua -lm -lz -lubootenv -Wl,--end-group ... ========== .../output/host/arm-buildroot-linux-gnueabihf/sysroot/lib/liblua.so: undefined reference to `dlopen' .../output/host/arm-buildroot-linux-gnueabihf/sysroot/lib/liblua.so: undefined reference to `dlclose' .../output/host/arm-buildroot-linux-gnueabihf/sysroot/lib/liblua.so: undefined reference to `dlerror' .../output/host/arm-buildroot-linux-gnueabihf/sysroot/lib/liblua.so: undefined reference to `dlsym' collect2: error: ld returned 1 exit status make[1]: *** [swupdate_unstripped] Error 1 The root cause is a missing "-ldl" in etc/lua.pc. This is probably wrong for all lua patches that add etc/lua.pc, although I personally only tested lua-5.3.4. The patch should apply to them too. I'm attaching the patch that I added to my buildroot external directory to fix the build problem.
