I used to use Kdevelop on Linux Mint which worked fine. Now I reinstalled Linux and I can't get Kdevelop and cmake to work.
When I compile I get this error:
make: *** No targets specified and no makefile found. Stop.
And when I try to configure cmake I get:
/home/benedikt/projects/Exercise 3/build> /usr/bin/cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Debug /home/benedikt/projects/Exercise 3/
-- Configuring incomplete, errors occurred!
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_3_COMPILER_ENV_VAR
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_3_COMPILER
CMake Error: Could not find cmake module file:/home/benedikt/projects/Exercise 3/build/CMakeFiles/CMake3Compiler.cmake
CMake Error: Could not find cmake module file:CMake3Information.cmake
CMake Error: CMAKE_3_COMPILER not set, after EnableLanguage
What do I have to set the variable to, and where do I do it?
Edit: The CMakeList.txt is:
project(exercise 3)
add_executable(exercise 3 main.cpp)
Take a look at project() command documentation.
Its first argument is the project name and others are used languages. CMake thinks that 3
is a programming language and tries to find its compiler.
Either remove spaces from project's name or use quotes: project("exercise 3")
.
