I have been having a lot of linker errors. I made sure to install all of the libraries I need via macports. I sorted out all of the include errors, but now I have a lot of linker errors left.

It looks like you are missing the required libraries gnutls, gcrypt and json to link against. Unless you tell Xcode what libraries to link against it won't have any idea. It will look something like this:
-lgnutls -lgcrypt -ljson
(That is an example, I am not sure what libraries specifically are required).
You'll want to add those as extra libraries to link against in your Xcode project.

I am trying to upgrade my react-native version from 63 to 67.4 and I have issues for the iOS part.
I have done bundle install yarn upgrade cd iOS && pod install and this is the issue I have after changing iOS deployment target from 10.0 to 11.0 as suggested in the react-native upgrade helper.

This is my lib configuration：
I searched Google and StackOverflow and found no related issues
As i am pretty much out of ideas and the google results by now have reached the point where they hit ~10 and less, i now turn here in hope of seeing the answer or at least a clue that leads me to the actual solution.
I am creating a project that can be distributed as executable, non-static library and static library.
I want to use the library in a WPF project (C#) which is why i created a simple CLR wrapper.
It all worked very well up until the most recent change introduced into the base-library.
Now, i get linkage errors (5 in total) on all calls to the "main" class in the library project:

The projects, can both be found here:
The C++ Project https://github.com/SQFvm/vm
The C++/CLR Project https://github.com/SQFvm/ClrBridge
Was able to get rid of the LNK2028 issues by adding another separation layer (wrapper.cpp & wrapper.h) and then putting a #pragma unmanaged at the top of the cpp file.
Only the LNK2019 issues are left now
For those users who may find this question in the future, here is what helped me:
Separating all classes
Adding #pragma managed to the an unmanaged wrapper for the actual class (got rid of the LNK2028)
One of the following commits:
Moving invalidly placed C method out of external "C" that is not involved in any way normally to the static library built but MAY intefere with the CLR build process as the header still was there
Altering the arangement of the constructor
Hope this helps you.
I am new in Kinect SDK, therefore I am asking for your help solving this problem:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
I am working with OpenNI2 and Nite2 and trying to compile one of the Nite2 Sample projects.
OpenNI2 doesn't support Kinect, as long as I know, maybe you can try with old OpenNI, at least that's what I learned, after trying the same, but I don't know under windows, I'm using GNU/ubuntu.
I'm trying to build an iPhone app using the OGRE framework, and I'm getting a linker error when building for the simulator that I'm not sure how to fix.
I created the Xcode project using the OGRE iPhone template. I'm using the static libraries for OGRE from the main website, Ogre_iOS_4.0_Dependencies_20100623, and trying to build for the iOS 4.1 Simulator. I'm building with Xcode 3.2.4 on Mac OS X 10.6.4.
Compilation seems to work fine, but when it gets to the link stage, I get the following errors:

How do I fix this? Thanks.
Probably you need correct precompiled Ogre dependencies for correct iOS SDK version (Masterfalcon regularly publish those dependencies on the ogre3d.org).
Similar linker errors often caused by incorrect iPhoneDependencies (build for older iPhoneSKD that you have).
Just follow the instructions as listed here:
http://www.ogre3d.org/tikiwiki/Building+Ogre+with+CMake
Secion "Configuring for iPhone".
All should build fine.
