CMake error "Expected a command name"

Question

I'm doing a shool assignment which involves CMake.

I'm trying to import the CMake project in CLion but I get the following error:

CMake Error at CMakeLists.txt:35: Parse error. Expected a command name, got unquoted argument with text "add_subdirectoryâ€‹".

The line specified is the following:

# Add terminal sub directory add_subdirectory(terminal) target_link_libraries(${Screen} Terminal)

The whole CMake file:

# Projektets namn project(Screen) # Minsta tillåtna cmake version cmake_minimum_required(VERSION 3.2) # Kompilera med c++ 11 stöd set (CMAKE_CXX_STANDARD 11) # Lägg till katalogen med våra bibliotek till INCLUDE path # (i dessa kataloger kommer kompilatorn att leta efter de # header filer som inkluderas i koden) INCLUDE_DIRECTORIES($ENV{TOOLS_INCLUDE}) # Ta med alla källkodsfiler i den aktuella katalogen och # lägger dem i listan SRC_LIST. aux_source_directory(. SRC_LIST) # Om Debug mode if (CMAKE_BUILD_TYPE STREQUAL "Debug") # Skriv ut meddelandet Debug mode samt sätt kompilator # direktivet DEBUG message("Debug mode") add_definitions(-DDEBUG) else(CMAKE_BUILD_TYPE STREQUAL "Debug") # Skriv ut meddelandet Release mode. message("Release mode") endif (CMAKE_BUILD_TYPE STREQUAL "Debug") # Skapa en exekverbar fil med källkodsfilerna i från # SRC_LIST. Första parametern är namnet på målet (Target) add_executable(${PROJECT_NAME} ${SRC_LIST}) # Add terminal sub directory add_subdirectory(terminal) target_link_libraries(${{PROJECT_NAME} Terminal)

Any ideas what I'm doing wrong here?

Please provide lines preceding your "add_subdirectory()" command. I suspect a missing closing parenthesis in previous command. BTH, your use of "add_subdirectory()" seems valid — Antwane

The command you used is:

add_subdirectory(terminal)

but the ( char is preceded and followed by a null char. This is invisible, but can be debugged using a hex editor, or any text editor that highlight this kind of error (I detected it using Sublime Text).

Simply replace this line by:

add_subdirectory(terminal)

Note: see the difference between 2 lines in HxD, a hexadecimal editor:

mmm I have the same problem but with an hexadecimal editor I see nothing of this sort
