The errors occured when using root as external library to write c++ code?

ROOT
1

I used CMake to configure c++ environment, it works at root version 6.22, for 6.24, the errors occurred (the errors from CMake):

ROOT_MultiProc_LIBRARY-NOTFOUND
ROOT_genmap_CMD-NOTFOUND
ROOT_rootbrowse_CMD-NOTFOUND
ROOT_rootcp_CMD-NOTFOUND
ROOT_rootdraw_CMD-NOTFOUND
ROOT_rootls_CMD-NOTFOUND
ROOT_rootmkdir_CMD-NOTFOUND
ROOT_rootmv_CMD-NOTFOUND
ROOT_rootrm_CMD-NOTFOUND

is there another environment variable except “path”

Please read tips for efficient and successful posting and posting code

ROOT Version: 6.24
Platform: windows 10
Compiler: VS2019

First, see:

And here is a very simple example of CMakeLists.txt:

# Check if cmake has the required version
CMAKE_MINIMUM_REQUIRED(VERSION 3.16.4 FATAL_ERROR)

set(PROJECT_NAME MyApp)
project(${PROJECT_NAME})

find_package(ROOT REQUIRED)

set(CMAKE_CXX_FLAGS "${ROOT_CXX_FLAGS}")
include(${ROOT_USE_FILE})
include_directories(${ROOT_INCLUDE_DIRS} ${CMAKE_SOURCE_DIR})
link_directories(${ROOT_LIBRARY_DIR})

add_executable(${PROJECT_NAME} MySourceFile.cxx )
target_link_libraries(${PROJECT_NAME} ${ROOT_LIBRARIES})

the content of my CMakeLists.txt is same as list up, it can work on ubuntu20.04, but not windows 10.

Well, I work on Windows and have several similar CMakeLists.txt. Did you call thisroot.bat before cmake ?

5

yes, i executed thisroot.bat file before CMake.

Oh, but wait, those are not real errors, you can still configure and generate you application, right?

with best regards!
