5 years ago Did you try the executable from commandline? Or by gdb on commandline? The cmake Tools does not use launch.json to start debugging. The Support for debugging with cmake Tools should work with cmake >3.7.1.

5 years ago Yes, i can run the executable from commandline. But when i "start without debugging", there is nothing output. Yes, you are right, only with cmake >3.7.2, according to Target Debugging and Launching, we can debug. I want to firstly to make the simple C++ project can run successfully with vscode.
-I have upgrade my gcc and g++ from 4.8.4 to 7.4 according to Install_gcc7_ubuntu_16.04.md,

-But when clean and rebuild in vscode, it still use g++-4.8, there is not g++-7 or gcc-7 in choosed kits.

5 years ago I solved this problem following these steps:
choose CMake type: Debug.
set cmake.cmakePath in user settings or in workspace settings with cmake > 3.7.2, for example:"cmake.cmakePath": "/home/jxl/cmake-3.13.1/INSTALL_JXL/bin/cmake",
build the project.
setting executable path in launch.json, "request": "launch", not "attach". for example.
"name": "(gdb) Launch", "type": "cppdbg", "request": "launch", "program": "/home/jxl/projects/test1/build/devel/lib/test1/test1",
ctrl + F5, not use vscode toolbar's Debug--->Start Debugging(F5), it doesn't work.set CMake type: release or debug.
Build project with any cmake version.
setting launch.json.
run executable with shift + F5, not use vscode toolbar's Start without Debugging, it doesn't work.
My VS Code version="1.30.1", ubuntu 14.04, when type cmake --version, its output is "cmake version 3.5.1" , g++ --version ="g++ (Ubuntu 4.8.4-2ubuntu1~14.04.4) 4.8.4". I also install some VS Code extension, C/C++ 0.20.1, CMake 0.0.17, CMake Tools 1.1.3. I can build c++ project successfully, but when i launch vscode, nothing output as if the executable not running, but in terminator, i can run the code. There is a screenshot of vscode after launch, something missing?? Thank you very much!
