I installed the Ogre3D iPhone SDK and tried to compile the sample project in XCode4. I ran into "lexical or preprocessor issue" which many people have been experiencing in XCode4. In my case, XCode was not able to fine "OgreCamera.h".
I managed to solve this problem by creating an "Indexing" group folder in my project and dragging the header files into it as suggested in this thread:
Compile, Build or Archive problems with Xcode 4 (and dependencies)
However, I ran into the same issue again in a different form. There are no more errors about "OgreCamera.h", but now I'm getting "'boost/thread/tss.hpp' file not found". I've dragged the boost folder and the individual boost header files into the Indexing group, to no effect.
All my include paths are configured correctly, XCode should be able to find these files based on my build settings.
I don't know what to do. I've searched for solutions to this and failed to find any. My best guess is that the contents of the Indexing group need to be a flat hierarchy with no sub folders, but Ogre references the boost headers files using a file path: "boost/thread/tss.hpp", and this causes problems for some reason. But I don't know how to go about fixing it.
Does anyone have any suggestions?
Thank you.
I had the same problem. I was copying boost into the root of the OgreSDK and then adding the following to my header search paths
$(SRCROOT)/boost
You'll notice the file being included is "boost/thread/tss.hpp". So using the above header search path it would be looking for $(SRCROOT)/boost/boost/thread/tss.hpp.
Assuming you have $SRCROOT/include in your header search paths - the solution is just to move the boost folder to your include directory.
PS... if you don't have a boost folder you'll need to download boost and copy it in there.

I've been reading countless other posts and trying numerous fixes, but nothing has worked for my problem. I'll preface this by saying that I haven't used Xcode on this Macbook in some 2-3 months. This is the only project (out of the 4 or so I've tried) that has this problem. The first thing I did after opening Xcode was I changed the name of the project as well as a .h and .m file. I did all of this through Xcode, not Finder.
Nothing is appearing in the Navigator in red text which would indicate that it can't be found. Here is what I've already tried (many times).
Close/Open Xcode.
Clean both the project and build folder.
Delete Derived Data folder.
Ran a Disk Utility to repair permissions.
Restarted the computer.
Tried different combinations of Code Signing.
Delete App from device.
Searched through project for any duplicate file names.
Here is the warning verbatim:
Warning: Multiple build commands for output file /Users/jinser/Library/Developer/Xcode/DerivedData/Landmarks-bgnzcomxftpffiezmwocaqdydrlj/Build/Products/Debug-iphoneos/Landmarks.app/Landmarks

This is Xcode 4.2 on Mac 10.6.8. Please, any advice would be appreciated. I am losing my mind.
Thanks.
So to whoever runs into this problem and all of the other solutions out there do not work for you, make sure you don't have a project folder that shares the same name as the project. For instance, my project is called Landmarks and I had a folder inside the resources also called Landmarks. Once I renamed the folder, all was well.
Not my answer, but LargeGlasses provided the real answer (for me) in a comment, I've formulated it as an answer in its own right because I can't Up Vote the comment.
any two files within your project that have the same name will cause this warning.
In my case, I had an icon with the same name in different subfolders, one was used by the App and the other was part of my help resource located in a different folder. The solution is to just rename one of the two.
All credit and my thanks for this answer to LargeGlasses.
I am new to this iPhone development and i have almost completed my first application but when i try for creating an archive it gives an error lexical or preprocessed issue file not found But it runs fine in simulator and also has also tested on device. I have included SDwebimage architecture for lazy loading of image in table view.Can any tell me what is the issue?
Few things to try, Ensure the Framework and all it's headers are imported into your project properly.
Also in your Build Settings set YES to Always search user paths, and make sure your User header paths are pointing to the Framework.
Finally, Build->Clean and Restart Xcode.
Hope this helps !
UPDATE: According to SDWebImage's installation, it's required you make a modification to Header Search Path and not User header paths, As seen below.
Have you done this as well? I suggest slowly, re-doing all the installation steps from the beginning.
Spaces in a folder name in your header search path can cause this problem. Make sure the folders in your project do not have spaces in their names.
My project was building fine until I updated to Xcode 10.1. After the Xcode update, started getting Lexical or preprocessor Issue errors on build. Some XCDataModel header files could not be found.
This fixed the issue.
Go to Build Settings, Header Search Paths
Change the appropriate value from $(SRCROOT) non-recursive to recursive.
This ensures that subfolders are also searched for headers during build.
I had this same issue now and found that my sub-projects 'Public Header Folder Path' was set to an incorrect path (when compared with what my main project was using as its 'Header Search Path' and 'User Header Search Path').
e.g.
My main project had the following:
Header Search Paths
Debug "build/Debug-iphoneos/../../Headers"
Release "build/Debug-iphoneos/../../Headers"
And the same for the User Header Search Paths
Whereas my sub-project (dependency) had the following:
Public Header Folder Path
Debug "include/BoxSDK"
Release "include/BoxSDK"
Changing the 'Public Header Folder Path' to "../../Headers/BoxSDK" fixed the problem since the main project was already searching that folder ('../../Headers').
PS: I took some good screenshots, but I am not allowed to post an answer with images until I hit reputation 10 :(
I had this problem after changed project name. I used all the methods mentioned on the internet but still doesn't work. Then I realized that all the header files not found was from cocoapods, so I re-installed the cocoapods using pod install, and thus solved the problem.
Hope this could help.
In my case I was developing a framework and had a test application inside it, what was missing is inside the test application target -> build settings -> Framework Search Paths:
The value needed to be the framework path (the build output - .framework) which is in my case:
"../FrameworkNameFolder/" - the 2 points indicates to go one folder up.
Also, inside the test application target -> Build Phases -> Link Binary With Libraries:
I had to remove the framework file, clean the project, add the framework file again, compile and this also solved the issue.
The new version contain fix for this, feel free to update.
Or you can just replace
#include "iPhone_View.h"
with
#if UNITY_VERSION < 450
#include "iPhone_View.h"
#endif
Delete the unit testing from your project follow the below steps this will solve the issue.
select your project from the project navigator to open the project editor. From the target delete the test from the left side of the project editor and press the Delete key.
I know this is old, but I'm gonna chime in anyway because it may be useful to someone. If you can still see the file in Finder, then click on the file in your project and delete it, selecting "remove references" and not "move to trash".
Once the reference is removed, drag and drop the file from finder into your project again and it should sort itself out.
Just adding another thing that worked for me :
react-native link
Evidently my ReactNative files were no longer there. I could figure that out by clicking on
Build Phases -> Link Binary with Libraries ->
Then right clicking a file I knew was responsible for React, and clicking Show In Finder .
But nothing opened. So assuming the library went missing, I just ran the above command which relinked everything again.
Also if you havn't, try :
rm -rf node_modules/ && npm install
This happened to me after I renamed a file. For some reason it was still looking for the file with the old name. What I did was create the file that it was complaining about and added to the project. Then I did a Project->clean, then Project->Build and verified the error was gone. Then I selected the newly added files and deleted them. This removed all references and I no longer see the error.
I fixed mine. The fb sdk downloaded (from my browser) as 'FacebookSDKs-iOS-4.22.0' -- I just had to rename the folder to FacebookSDK. So now in Build
Settings --> Framework Search Paths
the path looks something like /Users/.../Documents/FacebookSDK (where as before it was /Users/.../Documents/FacebookSDKs-iOS-4.22.0)
Hope this helps!
For what it's worth, my problem was completely unrelated to the error Xcode was giving. I stumbled onto a solution by deleting the .h reference, compiling, adding the reference back and compiling again. The actual error then became evident.
I am using the SDWebImage open source project for loading images asynchronously.
I can build & run for the simulator as well as for my local device.
However, when i try to build for distribution (i.e. Archive), the compiler doesn't seem to understand what the header file is:
import "UIImageView+WebCache.h" (no such file or directory).
I pretty much followed the instructions, with relative ease, described here on
github.com/rs/SDWebImage.
I knew things were going way too smoothily/easily to be true.
Oddly, i've never really faced an issue that is exclusive to Archiving.
Anybody tried Archiving with SDWebImage before?
* Updated *
I updated based on comment below. Now i am getting the following error while Archive building:
arm-apple-darwin10-llvm-gcc-4.2:
Poll/BuildProductsPath/Release-iphoneos/libSDWebImage.a: No such file
or directory Command
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/llvm-gcc-4.2
failed with exit code 1
The strange thing is that i have the sdwebimage.a file in my project (there's actually 2, one that i copied and included, and the 2nd one from the SDWEbImage project itself).
* Update 2 *
Upon further investigation, my SDWebImage project is NOT getting built when i Archive (the .a file is red). But any other build type works fine. I looked everywhere and it seems like the SDWebImage project has the distribution configurations. Not sure what else could be the issue here.
You can keep your setup as you have it. All that is needed is to add the header files to the search path. To add the needed header files to the search path do the following.
Select your project file
Select your target
Select Build settings
In the search box enter 'header search paths'
For the Release add "$(SOURCE_ROOT)/SDWebImage" (thats
with quotes).
This works when importing like this #import <SDWebImage/UIImageView+WebCache.h>
So, I have and may others had had this same problem. I worked on it for awhile this morning and found all the suggestions are not working.
How I got it to work is to add the Workspace lib to your project, as it stated in the instructions. Make sure the file isn't red, I had to play around removing it and adding the header search path again.
Finally, I was able to see the libSDWebImage.a file.
Right click on that file and "Show in Finder"
Move libSDWebImage.a and SDWebImage/.h files to a directory you will not delete
Add the libSDWebImage.a and SDWebImage/.h files to you project
You can archive now.
Hope it works for you.
I tried all of the above methods of adding header paths.. nothing worked. I'm able to build the project fine in debug but not archive. I just tried something simple and it did work.
The file "UIImageView+WebCache.h" is part of the subproject SDWebImage.xcodeproj.. In my main workspace project I simply did "Add File" and found the "UIImageView+WebCache.h" on disk and added it to my main project. Now that file is part of my main project. Ran Archive and it worked.. I little dumb, but it worked at least
I solved it very easily by adding (with quotes):
"$(SRCROOT)/SDWebImage"
to the various Header Search Paths under my project's Build Settings. Thanks to Lizard in SDWebImage/UIImageView+WebCache.h file not found for his solution.
For me this one worked, when addded to Header Search Paths (it is exact path to the SDWebImage project)
"$(PROJECT_DIR)/ProjectName/Libraries/SDWebImage"
I'm trying to use the Twitter libraries and after adding liboauth.a and adding oauthconsumeriphonelib to my header search path, I'm now down to 1 compilation error, which I can't seem to get rid of.
ld: library not found for -loauth
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1
Anyone know what could be causing this?
Continuing to What Robin suggested You also need to set the Library Search Path. Right Click the Target File and Choose -- Get Info else you can also get the same by choosing Edit Actice Target Under the Project Tab in XCode. Look for Library Search Path and add this "$(SRCROOT)/Twitter+OAuth/SAOAuthTwitterEngine" Where Twitter+OAuth/SAOAuthTwitterEngine is the directory path for Twitter Library in project folder.
I hope this will fix the problem.
Well #Nefsu you need to add those libraries to your project by adding an existing framework and then giving the path of the libraries you want to use.
And if you have already added the libraries by drag and drop, than dont remove them just add existing framework by right clicking on groups and folders and add the libraries from the folder and you will be done
I discovered this HIGHLY misleading message while trying to upgrade to the new Google Analytics library.
In my case the problem was having TWO CONFLICTING COPIES of the library. They were in different folders but both were listed in my App's Library Build Paths (under Build Settings).
Moving all the deprecated library files out of the folder ended up doing the trick and made the mysterious error messages go away.
After following all the instructions on http://three20.info/setup/existing to integrate three20 library into my project. I'm getting this linking error:
duplicate symbol _TTCreateNonRetainingArray in /test XYZ Photos App/Three20/Build/Products/Debug-iphonesimulator/libThree20Core.a(TTGlobalCore.o) and /test XYZ Photos App/Three20/Build/Products/Debug-iphonesimulator/libThree20.a(TTGlobalCore.o)
What can I try to resolve this?
Ok, after hours of figuring, I was able to solve this.. The answer is Three20 won't compile if your project is inside any parent folder with a space character.
I still had the same problem even after removing spaces in parent folder names (and deleting build cache, etc.), this is what worked for me (see https://github.com/facebook/three20/issues/issue/210/#issue/210/comment/526603):
In three20 install instructions step "2. Locate the "Three20.xcodeproj" file under "three20/src/Three20/" when I created a "Folder Reference" instead of a group reference, it worked. For the subsequent Xcode projects that get added, the "Folder Reference" radio was grayed out, but they all added properly and it worked after that (note that I had to re-do the subsequent step of adding Direct Dependencies to the targets).
When i was using the samples I met that problem, but there was no space in the name of my project folder. So i just downloaded a new project and compile correctly.
All necessary system libraries are linked such as QuartzCore and CoreGraphics?
Libraries set see in Samples of Three20: TTCatalog.
