I'm writing this Augmented Reality app for the iPhone and I'd decided to use ARToolKitPlus for it. Using QMake, I created the xcode project file and subsequently the libArToolKitPlus.dylib
I tried to compile and run the sample files "simple" and "multi" which worked well. Now all other attempts that I tried to create another project and use the library have failed due to header files not being found. If I drag the "include" folder to the xcode project I get 8 errors instead of just one; The one is for the main include not being found is solved but then it includes 8 other headers that cannot be found (although they are in the same folder)
#include "ARToolKitPlus/TrackerSingleMarkerImpl.h"
I get a error: ARToolKitPlus/TrackerSingleMarkerImpl.h: No such file or directory
If I drag the include folder then some of what I get:
error: ARToolKitPlus/TrackerSingleMarker.h: No such file or directory
error: ../src/TrackerSingleMarkerImpl.cpp: No such file or directory
error: expected class-name before ',' token
class TrackerSingleMarkerImpl : public TrackerSingleMarker, protected TrackerImpl<__PATTERN_SIZE_X,__PATTERN_SIZE_Y, __PATTERN_SAMPLE_NUM, __MAX_LOAD_PATTERNS, __MAX_IMAGE_PATTERNS>
Having the dylib doesnt make a difference as far as I can tell. What do you think I should do?? Would creating a framework help??
I'm not sure its ok "copyright wise" to do so. But here's how to do it.
In XCode, create a new group called: ARToolKitPlus (or whatever u like).
Drag the "src" and "include" folders from the original ARToolKitPlus folder to the group you created.
Find the location of both the "include" and "src" folders by right clicking on each and selecting "Get Info"
Copy these paths in the "Get Info" window.
Open the project settings, choose "All configurations" and find "Header Search Paths", you can search for it directly.
Add the paths you copied from the info window to the header search paths, make sure you compensate for spaces (or even better, have no spaces in your paths).
Confirm and make it recursive, and voila!
I figured this out... It was an xcode problem, it was not including the "include" folder in the header search path. Did that manually and the problem was solved!

I am unable to find the problem of this Error. Can anyone guide me. How to fix given below error.
I had added the revmob sdk in my project and i had also checked the box "Copy to destination if needed." And i also checked it is there in the xcode project. but still given below error is not going. This not my first time i am integrated revmob. but do not know why suddenly this error starts appearing even this code is working fine before.
Error
'RevMobAds/RevMobAds.h' file not found
I call this the "Phantom Folder issue"...
I had an issue where I deleted the RevMobAds.framework from within Xcode but when I tried to re-add the newer SDK by dragging and dropping into Xcode into a different folder (copy was checked and targets were checked), it would appear then give me the same error: 'RevMobAds/RevMobAds.h' file not found
It turns out that when I checked the real project folder in Finder (not from within Xcode) that an empty RevMobAds.framework folder was left behind.
So what I did was:
(1) From Xcode, deleted the RevMobAds.framework that I had added.
(2) Went to the real project folder in Finder and deleted any phantom/leftover folders named RevMobAds.framework that were still there.
(3) Dragged the RevMobAds.framwork SDK back into Xcode (making to sure to check COPY and targets).
And this solved the problem for me.
Right Click on your App in groups and files section, Select Add files to "your app"....
Once you do that, select folder you want to add and select "Copy items into destination group's folder (if needed)" as shown in screenshot below.
Note: Copy items into destination group's folder (if needed) is to be selected only if the files are physically in some other folder and not the application bundle or application folder.
Ok, finally I managed to solve this. I read a lot of questions here, and searched online.
This article help me out a lot.
So, what happened to me, is that the library files, that were giving to me were missing some files and shortcodes.
So, I just:
Downloaded the new version of the library. Link here.
Copy to my project folder.
Add it to the Header Search Path. (Build Settings, Search Path, Header Search Paths. Add something like $(PROJECT_DIR)/RevMobAds.framework)
And a Clean, Build.
And that's it.
I imported one project to another project by following this link tutorial
successfully build that two project. But when I added
#import <SampleSubproject/SampleSubproject.h> this to my main ViewController.m file error be occur.
Error : "SampleSubproject/SampleSubproject.h" file is not found.
Why is that error occurred ??
Is there any error ?
Please help me guys!
You have Headers search path settings at project configuration. Let's say there're directories A and B. With "SampleSubproject/SampleSubproject.h" Xcode looks for SampleSubproject.h at A/SampleSubproject/SampleSubproject.h and B/SampleSubproject/SampleSubproject.h. If there's a checked recursive flag for any directories, the search is performed at this directories and their subdirectories.
Now you'll need to check what is the headers search path for the target you are building keeping in mind that you might have several targets and the file with the import might not be included into all the targets.
As you also have a red library, you'll want to check the Libraries search path as well, it works in the same way.
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 simply trying to add a file to my Xcode resources folder and it fails claiming the file already exists, which simply isn't true.
I assume it has a record of the name and is confusing itself, I tried performing a 'clean' but this didn't help. Any ideas? Thanks!
click on project and get info.Then search for the file.And then delete it.
Try fully closing/re-opening Xcode and failing that, reboot yet?
Just to be sure, use the file filter at the bottom of the project navigator to triple check the file is not there.
If the file is definatly not in the project sometimes Xcode gets confused when you delete a file and the file may actually be on disk. So check the actual project directory on disk to ensure that your file is not in there.
Quick way to get to your project directory, right click the project file (or any file) and select Show in Finder or at the very top of the Xcode window cmd + click the project title and select the folder it is in.
