Xcode 4 and Allegro 5.1 - Linker can't find Framework - xcode

I know there are several other questions here regarding the Linker and Xcode 4, but they don't really relate to my problem.
I've built Allegro 5.1 and it took me a while because of FreeType, but eventually it worked. Now I've written a little Space Invader game using Allegro. But somehow the linker can't find the framework.
What I've done so far:
The Frameworks are located at /Library/Frameworks/ and they have the same structure like all the other frameworks in that place
I've added the frameworks to the "Link Binary With Libraries" tab of my target
I've added them in a "Copy Files" tab on my target with Destination "Frameworks"
I've added the correct path settings in the Build Settings, so the header files can be found
I've done all the right steps, but still I get:
ld: framework not found Allegro-5.1
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I already had a working framework, but it was installed as shared libs and not in "framwork mode". But adding the framework components to the project was kinda hard because they were stored in /usr/local/lib, which can't be selected with the file dialog...
So... I have no idea what else there should be to do. When I had the shared libs it worked, but now with the same setting but different location it doesn't anymore. Tell me if you need more information, I'll provide it!

So, in case someone lands here, with the help of elias in the Allegro IRC I've found the "error":
In my targets Build Settings I had to specify the Framework Search Paths as /Library/Frameworks.
This doesn't really make sense to me, since this is the default directory for the Frameworks on Mac OS X, but whatever...

Linker error building Adobe DNG SDK on MacOS 11

I am working on a project that uses Adobe's DNG SDK 1.6 library, and it is supposed to work on Windows and MacOS.
The library has instructions on how to build it for both platforms, but I had to figure out an error that came up on Windows with Visual Studio. I am not very experienced with big C++ projects so it was not trivial but I got it working. Most of my own code will be done in C# .Net Core, calling the native libraries using a wrapper class with P/Invoke.
Now for Mac that's a different story, I have a MacOS 11 VM, installed Xcode 12.5.1 and followed the steps provided, as expected, it does not work. Bare in mind this is my first time touching Xcode and MacOS.
The project I am trying to build is dng_validate, and it depends on two libraries built by these projects: XMPFiles64 and XMPCore64.
The library projects build without any hiccups, each one of them creating a ".a" file in the folder: dng_sdk_1_6/xmp/toolkit/public/libraries/macintosh/intel_64_libcpp/Debug, they are named libXMPFilesStaticDebug.a and libXMPCoreStaticDebug.a respectively.
When I try to build the dng_validate project, I get the following error:
Library not found for -lXMPFilesStaticDebug
Because of the the error starting with an "l" instead of "lib", under both libraries project settings, I changed the "Executable Prefix" setting to "l" instead of "lib". Rebuilt both of them and made sure the file names changed as expected. But the error persists when trying to build the main project.
Under dng_validate's project settings, there is a setting called "Library Search Paths" and it does point to the proper aforementioned folder using a relative path. I even changed it to an absolute path to see if that would make it work.
I am really lost here, does anyone have an idea of what might be causing it?
Well... After asking on other forums and almost hiring a freelancer to fix this for me, I tried another shot in the dark of renaming the library files and it worked.
I changed the extensions of libXMPFilesStaticDebug.a and libXMPCoreStaticDebug.a from ".a" to ".dylib" and it just compiled and blew my mind with it.

XCode Project - ld: library not found for -llib

Recently I ran into a CMake problem that can be found in this thread:
Cmake on OSX Yosemite 10.10.3 - GLEW: package 'gl' not found
Eventually it got solved, maybe partly due to my inexperience in XCode and CMake. (I mainly used visual studio to compile projects in the past.)
After the alteration in the linked thread I got warning about my GLEW libs in CMake
(Is this something I should be worried about or is it not important?):
MACOSX_RPATH is not specified for the following targets:
GLEW_MX_shared
GLEW_shared
I simply ignored it and tried to compile my project in XCode with the ALL_BUILD target selected. In the sparky target it said the include files in main could not be found so I added the .h files into the inc folder of my project.
When I compiled again the compiler started complaining again
(I don't know what this error means and how I can fix it.):
ld: library not found for -llib
Googled it for the entire day now and I can't find anything to solve this issue.
It's so frustrating working with XCode as an IDE but I really want to learn more about different platforms and their most popular IDE's so I can make multi platform applications from the start instead of porting it afterwards.
And if it matters I am using OSX Yosemite 10.10.3.
To make my issue easier to understand, I've put a zip of my project on my dropbox.
https://www.dropbox.com/s/xnrh90kuih9ia5a/SPARKY%202.zip?dl=0
Feel free to ask questions if I explained things to briefly and again, thanks to everyone who contributes here. I really learned allot after discovering these forums.
EDIT: Alright I booted up my windows machine, generated a visual studio environment and tried to build it on there. Seems that the same problem also happens here. I looked at the linker attributes/flags and saw a lib.lib file added to the linking process which doesn't look right at all.
When removing the file, the error disappeared and many others arrived! (Which are simply solved by linking the appropriate libs so I wont handle those here.)
I misunderstood the error on my mac and thought it was referring to a random library which I needed to hunt down but actually it's a inconsistency in one of my CMake files.
EDIT2: Now I only have to find out where the lib.lib comes from and how I can ditch the flags from the project so I can generate my environment and build right away!
So moral of the story. Sometimes the solution is right in front of you and still ends up more like looking for a needle in a haystack.
I removed the following from my root CMakeLists.txt file and the random lib.lib library was gone from my generated projects
SET( PROJ_LIBRARIES "lib" )
I thought this added a folder containing libraries but actually what it did was adding another flag for a specific library because this variable was being fed to:
TARGET_LINK_LIBRARIES( ${PROJ_NAME} ${PROJ_LIBRARIES} ${OPENGL_LIBRARIES} ${GLEW_LIBRARIES} )

Swift: App Installation Failed Could Not Inspect The Application Package (When Using Frameworks with XCode 6)

I'm having difficulties running a compiled app on an iPhone 6 (iOS8). It works fine in the simulator.
I get this error message:
App installation failed
Could not inspect the application package
Originally there were error messages - such as the one here but I fixed this temporarily by moving the output into the correct location. However even though all of the libraries are being codesign'ed correctly and are now found I am unable to use the app on my device.
There seems to be no further error messages and therefore no way of debugging anything. How exactly do normal iOS developers debug problems which give no error messages?
I guess the underlying problem is that my project is getting quite complex, there are a lot of moving pieces: a few cocoapods, Alamofire, ReactiveCocoa, and Moya.
I have a few general questions:
Where can I find information that documents the use of frameworks in XCode 6?
What is the difference between "Build Phases -> Link Binary With Libraries", "Build Phases -> Copy Files", "General -> Embedded Binaries" and "General -> Linked Frameworks and Libraries"?
Everything is compiling completely fine for the simulator, including the cocoapods, but I note that there are libPod.a files and wonder whether they need to be compiled into the app?
Mostly I am hoping to find some way of finding out why the application package can't be inspected. Surely whatever software that inspects this must be able to be debugged?!!
Edit:
For the record, (1) there is no file called Resources in the root folder as I get nothing back when I do this "find . -name Resources" so it cannot be that issue, (2) I have run "Product -> Clean" and then tried to build again and this does not solve the problem either, (3) the Info.plist does contain a CFBundleName which is set to "${PRODUCT_NAME}" currently (which I believe is set elsewhere.)
I managed to fix this. I am not sure exactly what the solution was, but effectively what I did was to remove all of the cocoapods, detach all of the extra projects that were being used to compile frameworks, and then completely clean the build folder (by holding Alt while going to Product > Clean.)
I then added each of the frameworks back and made sure that each of them would compile.
I checked the build output and near the bottom of each I was able to find the location in which the frameworks were being built.
I then went back to the parent app, and was able to change the framework search paths to include the folders that the frameworks were being built in.
I may have changed a couple of other paths, too, though I cannot remember completely.
I think that basically the issue was a combination of (1) a very dirty build path, (2) leftover files and bad configuration causing issues, (3) frameworks being built in the wrong location.
check your "Copy Bundle Resources",delete info.plist if it contained.
It's work for me in Xcode 6.4

linking glfw static library with Xcode 4

Okay I've been searching for hours to try and solve this but nothing has worked. This problem is very similar to other posts, but I none of their solutions work.
So I am writing an OpenGL program using glew and glfw and for some reason I am unable to get the program to compile. The error is on the include statement:
#include <GL/glfw.h>
and the error says 'GL.glfw.h' file not found.
I have followed all the instructions on the
GLFW-2.7.8 Release Notes
web page, which includes making glfw, and then importing the static library libglfw.a into Xcode. The library does show up under Build Phases -> Link Binary with Libraries, but apart from that Xcode doesn't seem to recognize it. For example, under the File Inspector it detects the file type as "Default - data".
The static library is configured for 64-bit architecture, which I am running.
I have tried changing the search paths under Build Settings.
I have the following frameworks included: Cocoa, OpenGL, and IOKit.
Please let me know if there is any more information you need to help me solve this problem and thank you for reading.
It turns out my glew was not importing correctly and so glfw did not work either.
These are the steps I took:
Changed the Base SDK from Latest OSX (10.8) to Current OSX.
After doing this, I "reduced" the error to an Apple Mach-O Linker (Id) error. Next:
Added -lGLEW to Other Linker Flags.
Added /opt/local/include/ to the header search paths
Added /opt/local/lib/ to the library search paths
Here is where I found my answer.

Adding Static Library to xcode not working

I added a static Library and its header file to my OSX project and added them to Link Binary With Libraries under Build Phases.
Xcode gives me the following warning
ignoring file /Users/sd1212/Desktop/OpenGLPlugin/libClientLib.a, file was built for archive which is not the architecture being linked (x86_64)
and wont let me call any of the library methods. I thought I had an architecture problem, so I looked online... Maybe the instructions weren't clear or something, but I think that I already have the x86_64 architecture added, and I changed "Build Active Architecture only" to "No."
Here is a screen shot of the project's architecture settings
Please help! Thanks in advance
Look at the project that builds the static library, as well as the project that links to it, and make sure they both build the right architecture. Consider not only the Valid Architectures line, which you highlighted in your screen shot, but also the Architectures setting. The ones that get built are the ones in both lines.
