How can I include INAppStoreWindow into my existing xcode project?
When I simply include this:
#import "INAppStoreWindow.h"
I will get a error, that it is not existing. I read that I have to compile with linker flag
-fobjc-arc
But, I don't know how to get that working.
Can someone please help me?
For any questions, please let me know
you need to set compiler flags to -fno-objc-arc for INAppStoreWindow.m file. To Set this go to Target->Build Phases->Compile Sources->INAppStoreWindow.m and set the compiler flags to -fno-objc-arc.
To set A linker flag you should go to your project file
Target->Build Phases->Compile Sources->INAppStoreWindow.m
(See image Below)
Double click the INAppStoreWindow.m file
and add the -fno-objc-arc. flag to it.

I'm using the -imacros option for GCC in order to set all preprocessor defines (Options) for a project.
Before imacros I have been using a raw file with the preprocessor defines names and with a regular expression in CMAKE I was creating the list of -D to put in the CMAKE_C_FLAGS.
This works fine but ugly to see in the text editor. So to enhance that, I have changed to -imacros.
CMAKE_C_FLAGS will contain -imacros "path to configuration header"
This works fine, but if I change some configuration item in the configuration header the CMAKE do not recompile the file (don't see changes). In the old version - as you can expect - if some -D was changed all the files will be recompiled.
Any help?
An simple Approach
You can use OBJECT_DEPENDS source file property. But that needs to be set for all source files with something like:
set_source_files_properties(
${sources}
PROPERTIES
OBJECT_DEPENDS "path to configuration header"
)
Alternatives for all Source Files in Project
Officially CMake recommends to put all your definitions in a header file that is included by all your source files. The header could e.g. be generated from a template using configure_file().
But to follow your line of thought with using -imacros compiler flag, here are two alternative approaches for triggering a rebuild of all source files if "path to configuration header" file changes:
You can extend the scope of OBJECT_DEPENDS to all targets and their source files in the current directory with define_property(... INHERITED ...):
If the INHERITED option then the get_property() command will chain up to the next higher scope when the requested property is not set in the scope given to the command. DIRECTORY scope chains to GLOBAL. TARGET, SOURCE, and TEST chain to DIRECTORY.
So in your case this translates to:
define_property(
SOURCE
PROPERTY OBJECT_DEPENDS
INHERITED
BRIEF_DOCS "brief-doc"
FULL_DOCS "full-doc"
)
set_directory_properties(
PROPERTIES
OBJECT_DEPENDS "path to configuration header"
)
If I understand correctly, you anyway have to re-run CMake if your "configuration header" should/would change. Then you can simply add one definition outside your "configuration header" that keeps track of the header with something like:
file(TIMESTAMP "path to configuration header" _timestamp)
add_definitions(-DIMACROS_TIMESTAMP=${_timestamp})
Now every time your header gets a new timestamp, the definitions for all targets are changing and your build system will rebuild all source files.
I created a Bindins Library project, I used sharpie, I added the frameworks I needed in the .linkwith.cs.
But I also need libicucore.dylib and libstdc++.6.0.9 and I don't know how to add them.
I'm also not sure about other parameters like SmartLink and LinkerFlags.
This is in the .linkwith.cs file, but do I need to add something in the main project under Additional mtouch arguments"?
Thanks
You can pass the extra linker flags via .linkwith.cs file:
LinkerFlags = "-lstdc++.6.0.9"
LinkerFlags = "-licucore"
You can pass multiple linker flags:
LinkerFlags = "-licucore -lstdc++.6.0.9"

I'm trying to compile the MultiBoost Library with C++11 but I can't make it work. The problem seems to be with the BZip2 Library that is used internally. More specificly there is a wrapper called Bzip2Wrapper to provide a c++ interface to the C library. All the files of the C library are included in the same folder. When using the default make file everything works but when I change
project(multiboost)
to
project(multiboost CXX)
I get the following errors:
libMultiBoostLib.a(Serialization.cpp.o): In function `Bzip2WrapperReader::open(char const*)':
Serialization.cpp:(.text._ZN18Bzip2WrapperReader4openEPKc[_ZN18Bzip2WrapperReader4openEPKc]+0x97): undefined reference to `BZ2_bzReadOpen'
Serialization.cpp:(.text._ZN18Bzip2WrapperReader4openEPKc[_ZN18Bzip2WrapperReader4openEPKc]+0xc5): undefined reference to `BZ2_bzReadClose'
libMultiBoostLib.a(Serialization.cpp.o): In function `Bzip2WrapperReader::close()': ...
The CMakeList file looks like this
# Bzip2
file(GLOB bzip2_SRCS "${BASEPATH}/Bzip2/*.cpp" "${BASEPATH}/Bzip2/*.c" "${BASEPATH}/Bzip2/*.h")
add_library(Bzip2Lib STATIC ${bzip2_SRCS})
#add_library(bzip2 SHARED ${bzip2_lib_SRCS})
...
# adding library to the exec
target_link_libraries(multiboost MultiBoostLib Bzip2Lib)
Any ideas what could go wrong? I don't even know what the problem is.
Thanks!
This does not look like a C++11 error but an error in the Build system.
I have not looked at the Code, but from the output you added something like this
target_link_libraries(MultiBoostLib PUBLIC Bzip2Lib)
should add the missing dependency from libMultiBoostLib on libBzip2Lib.
I found the problem. I was adding "CXX" to my project description which disabled the use of C. Therefore the libraries (in C) could not be compiled. Changing it to "project(name C CXX)" solved this issue. I then also needed to include the line "set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")" to enable C++11 support. Now everything is working.
Thanks a lot!
Vísual Studio >=2010 does provide to configure system directories in the VC++ Directories section. Is there any way to tell CMake to fill these settings instead using C/C++/Additional Include Directories?
Since cmake 3.12 you can use variables like CMAKE_VS_SDK_INCLUDE_DIRECTORIES to setup "VC++ Include Directories".
Simply add the following line to your CMakeLists.txt:
include_directories(-your-include-folder-)
Similarly, add the following line if you want to set the library directories:
link_directories(-your-library-folder-)
As Min said, you can set CMAKE_VS_SDK_INCLUDE_DIRECTORIES now. Thank you Min!
I'll leave a working example for the next person that ends up here like I did.
cmake_minimum_required(VERSION 3.18)
# ...
if (MSVC)
# Example for a library that only exports as module without xxx_DIRS variables.
get_target_property(SDL2_image_INCLUDE_DIRS SDL2_image::SDL2_image INTERFACE_INCLUDE_DIRECTORIES)
# Join all include dependencies in a list
set(_DEPS_DIRS ${SDL2_INCLUDE_DIRS} ${SDL2_image_INCLUDE_DIRS} ${OpenCV_INCLUDE_DIRS})
# Make all slashes turn into backslashes
cmake_path(CONVERT "${_DEPS_DIRS}" TO_NATIVE_PATH_LIST _NATIVE_DIRS NORMALIZE)
# Set the "VC++ Directories > Include Directories" setting
set(CMAKE_VS_SDK_INCLUDE_DIRECTORIES "$(VC_IncludePath);$(WindowsSDK_IncludePath)" ${_NATIVE_DIRS})
unset(_DEPS_DIRS)
unset(_NATIVE_DIRS)
endif()
Important: To troubleshoot first delete the build folder and start from scratch.
I believe previously (before v3.18?) cmake added the list to the "Additional Include Directories" setting, but I think they removed it because those are added with /I compiler option, and now it seems included dependencies are added with /external:I if you look at Command Line settings in the project, and they may conflict? Not confirmed, just a thought.
Don't use target_include_directories or include_directories just for this. With modules you shouldn't need to, only use it if you already had to.
Also even if possible shouldn't include all headers as dependencies to add_executable, that's inconvenient.
Now that ZXingObjC can be used as a framework I can't figure out for the life of me how to add it to my project. I followed the instructions on the git page https://github.com/TheLevelUp/ZXingObjC, but when I add #import <ZXingObjC/ZXingObjC.h> xcode can't find the file. The example projects that they provide, however, compile fine.
Current answer would be http://cocoapods.org.
Put
pod 'ZXingObjC' into your podfile.
The file below does not exist in library header files.
#import <ZXingObjC/ZXingObjC.h>
Also set library header file path in Search Header Path in Build Settings. and import file as per your requirement.
