set(SOURCE_FILES log.cpp remote.cpp netvar.cpp hack.cpp main.cpp)
add_executable(csgo_external ${SOURCE_FILES})
target_link_libraries(csgo_external "-lX11")

Я пытался создать его, также.

, Таким образом, я получил ту же ошибку. Я нашел причину, почему эта ошибка происходится.

-lX11 не cflag (compile flag), это - флаг ссылки. Таким образом, этот флаг должен быть в link flags, а не cflags. https://cmake.org/cmake/help/v3.0/command/target_link_libraries.html

страница Above описывает о том, как установить флаги ссылки. Таким образом, я изменил CMakeLists.txt следующим образом.

cmake_minimum_required(VERSION 2.8.4)
project(csgo_external)

#removed -lX11 from following line.
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -m32 -std=c++11")
set(EXECUTABLE_OUTPUT_PATH ./build)

set(SOURCE_FILES log.cpp remote.cpp netvar.cpp hack.cpp main.cpp)
add_executable(csgo_external ${SOURCE_FILES})
#appended following line.
target_link_libraries(csgo_external "-lX11")

кроме того, удостоверьтесь, что Вы имеете libx11-dev:i386, а также libx11-dev

Примечание: Файл CMakeFiles/csgo_external.dir/link.txt создается командой cmake .. После того как этот файл был изменен, выполнял команду cmake не снова, иначе Ваши изменения будут перезаписаны. Настоящая проблема находится в CMakeLists.txt. Поэтому примечание в конце ответа.


Проблема находится в CMakeFiles/csgo_external.dir/link.txt после выполнения cmake. -lX11 должен прибыть после

[…] CMakeFiles/csgo_external.dir/main.cpp.o

или в конце.

Отредактируйте файл CMakeFiles/csgo_external.dir/link.txt

nano CMakeFiles/csgo_external.dir/link.txt

и замена

/usr/bin/c++ -m32 -std=c++11 -lX11 CMakeFiles/csgo_external.dir/log.cpp.o CMakeFiles/csgo_external.dir/remote.cpp.o CMakeFiles/csgo_external.dir/netvar.cpp.o CMakeFiles/csgo_external.dir/hack.cpp.o CMakeFiles/csgo_external.dir/main.cpp.o  -o build/csgo_external -rdynamic

с

/usr/bin/c++ -m32 -std=c++11 CMakeFiles/csgo_external.dir/log.cpp.o CMakeFiles/csgo_external.dir/remote.cpp.o CMakeFiles/csgo_external.dir/netvar.cpp.o CMakeFiles/csgo_external.dir/hack.cpp.o CMakeFiles/csgo_external.dir/main.cpp.o  -o build/csgo_external -rdynamic -lX11 

После этого свяжитесь с разработчиком. Они должны изменить что-то в CMakeLists.txt.
