Hey @miconda, These files are generated from other files and do not exist in the source tree, when configuring. They are produced during the build step and therefore I needed to find a way to list them at sources so they don't produce the errors above. If you search `CMakeLists.txt`, you can see the `custom_commands` that generate them and `CMake` knows not to error if not found because they are `OUTPUT` of these commands and instead built them. I haven't seen these warning before. ``` - warnings shown before: Warning: Source file ".../src/core/lex.yy.c" is listed multiple times for target "kamailio". Warning: Source file ".../src/core/cfg.tab.c" is listed multiple times for target "kamailio" ``` Did you make any change before that might included this? There is only one place that list this source files as source and its here ``` target_sources( kamailio PRIVATE ${kamailio_SRC_FILES} ${CMAKE_CURRENT_BINARY_DIR}/core/lex.yy.c ${CMAKE_CURRENT_BINARY_DIR}/core/cfg.tab.c ) -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/commit/da629accb2c2095e3255f4aa3389a0a… You are receiving this because you are subscribed to this thread.
