CMake unable to determine linker language with C++
Try changing
PROJECT(HelloWorld C)
into
PROJECT(HelloWorld C CXX)
or just
PROJECT(HelloWorld)
See: https://cmake.org/cmake/help/latest/command/project.html
CMake can not determine linker language for target - C++
I've had this error many times :( Add this to your CMakeLists.txt:
set_target_properties(IEngine PROPERTIES LINKER_LANGUAGE CXX)
CMake Error: CMake can not determine linker language for target: myapp
CMake probably can not determine linker language for target myapp
, because the target does not contain any source files with recognized extensions.
add_executable(myapp vmime)
should be probably replaced by
add_executable(myapp ${VerifyCXX})
Also this command
set_target_properties(${TARGET} PROPERTIES LINKER_LANGUAGE Cxx)
cannot be succesfull, because ${TARGET}
is used-before-set. You should call it after add_executable
set_target_properties(myapp PROPERTIES LINKER_LANGUAGE CXX)
Note that usually it is not needed at all.
CMake Error: CMake can not determine linker language for target The errors appeared when I catkin_make a ROS working space
I have solved the problems. These errors caused by lacking of set_target_properties(XX PROPERTIES LINKER_LANGUAGE C++) after every add_library().
CMake Error: Cannot determine link language for target
Try this in your SmartSingleton/CMakeLists.txt
file:
set_target_properties(SmartSingleton PROPERTIES LINKER_LANGUAGE CXX)
This will directly tell CMake which language to use for that target.
If your library is truly only header files though, you will likely receive the error you mention also. Consider making this library an INTERFACE
library:
add_library(SmartSingleton INTERFACE)
target_include_directories(SmartSingleton INTERFACE include/)
Here are the docs for INTERFACE
libraries.
CMake cannot determine linker language for target
You have added target for creating container
library. That target contains only header files. See CMake documentation
add_library: Add a library to the project using the specified source files.
add_library( [STATIC | SHARED | MODULE]
[EXCLUDE_FROM_ALL]
source1 source2 ... sourceN)Adds a library target called to be built from the source files listed in the command invocation. The corresponds to the logical target name and must be globally unique within a project. The actual file name of the library built is constructed based on conventions of the native platform (such as lib.a or .lib).
But you can not build library just from header files without any cpp file. That's why you got such error.
Android Studio Cmake cannot determine linker language for target
If CMakeLists.txt
is in src/main/cpp
directory (this is how the AS wizard generates a C++ project), then you should say
add_library( # Specifies the name of the library.
iob
# Sets the library as a shared library.
SHARED
# Provides a relative path to your source file(s).
iob.c )
Relative paths to source files are calculated relative to the CMakeLists.txt
.
CMake can not determine linker language for target: fileloader
Added:
SET_TARGET_PROPERTIES([some name] PROPERTIES LINKER_LANGUAGE C11)
to the end of my program and the error went away. After reading a million web pages I found https://kuniganotas.wordpress.com/2011/05/25/error-cmake-can-not-determine-linker-language-for-target/ and the solution was literally that simple! Hopefully this can help others with this error!
CMake can not determine linker language for target: azurestorage error
I've given your example a try and the relevant error message is more to the top of CMake's output:
-- Unsupported Build Platform.
So if you want to add it, don't use ExternalProject_Add()
. The library's included CMakeLists.txt
is for Unix/Linux/OSX.
But it comes with an existing .vcproj
for VS2015 which you can include into your project with include_external_msproject()
:
find_package(Git REQUIRED)
execute_process(
COMMAND "${GIT_EXECUTABLE}" clone https://github.com/Azure/azure-storage-cpp.git
)
set(NUGET_EXECUTABLE "${CMAKE_CURRENT_BINARY_DIR}/azure-storage-cpp/tools/NuGet.exe")
execute_process(
COMMAND "${NUGET_EXECUTABLE}" restore "azure-storage-cpp/Microsoft.WindowsAzure.Storage.v140.sln"
)
include_external_msproject(
azurestorage
"azure-storage-cpp/Microsoft.WindowsAzure.Storage/Microsoft.WindowsAzure.Storage.v140.vcxproj"
)
