You can workaround this issue by removing the flag -Werror which turns all warnings into errors.

Sorry, but I'm not a Linux nor C++ advanced user, how could I remove this flag?

Thanks in advance.

The flag seems to be coming from gtest. You can skip running the tests entirely by commenting out these lines:

leela-zero/CMakeLists.txt

Lines 133 to 135 in 3ee6d20

	file(GLOB tests_SRC "${SrcPath}/tests/*.cpp")
	add_executable(tests ${tests_SRC} $<TARGET_OBJECTS:objs>)

Note, to comment out a line in CMake you can prepend it with a #

Additionally note, that Leela Zero has been an abandoned project for several years now. There are more up to date Go AI projects, if you just want a Go AI and not specifically want to test Leela Zero. The major one is KataGo.
