How can make scan-build work? - objective-c

I'm trying to use xcode scan-build tool, but the folder created is deleted with the error:
“scan-build: Removing directory ‘/var/folders/3g/……’ because it contains no reports.”
I want to use this tool since it can create a report that can be read by our CI Server (Jenkins).
I believe that my problem is related to some configuration in my xcode project since with other projects it works and creates the report.
Do you have any clue what may be wrong?

Xcode: weird build failure when duplicating a build configuration

I duplicated an existing build configuration in my Xcode project called Direct and named it Setapp.
I didn't modify anything regarding the new build config Setapp, however, when I build using the Setapp build config, I am getting an error.
It says the library Ensembles cannot be found. It's a library that I installed via Cocoapods.
I can't figure why I am getting this error. Since I am using an exact copy of a build configuration that works (Direct in this case), I don't see how Direct builds fine but Setapp doesn't.
Just as extra information, I am specifying to build using the Setapp build configure using Scheme like this:
Any ideas?
Turns out I need to run pod install again.

Using CMake in Embarcadero

I am trying to get CMake to work with Embarcadero 10.2.3 (Tokyo). I see a some help and blogs. I looks fine (I haven't tried so far), but I get confused about the existing cbproj file that I have. I get the impression that I need a CMake file list (CMakeLists.txt) as well as a cbproj file, if I need to build from the IDE. So in that case, any time I need to add files or settings I need to do in both. Is this true?
Thanks.

any way to run intellij community build from altered source?

I made changes to Intellij Community Edition (ce). I can compile and run those changes from within the IntelliJ editor. That launches a second instance of IntelliJ ce which is running from classes containing my changes. What I want to do is just run those changes without having to first load the source, compile and run from within IntelliJ.
Netbeans made this easy by just producing an executable as a result of the build. With Intellij, it's not at all clear what has to be done. I have tried the following-
using the Run configuration Intellij itself uses to run the altered classes- this includes setting the working directory , main class, vm options and classpath. Actually, this doesn't work for reasons unknown to me.
on someone's suggestion, running dist.gant in build. This blows up with very many errors which are not helpful (no class def found errors which indicate some confusion on Intellij's part on classpaths somewhere)
Running WinLauncher.exe under bin gives the error message that it can't find VM options file (although it's in bin, (and also for good measure under bin/win with the other files which are co-located with vmoptions in the intellij directory structure for Intellij proper. )
ALl this is just harder than it should be. The solution is to provide an executable as a result of the build and place it in a predictable location.
Has anyone ever actually DONE what I am trying to do- make changes to the community source then use the resultant editor not as a project you're working with in IntelliJ but as the Intellij editor you're working through?
FOLLOW UP
User60561 had the correct answer. Just to mop up the details, in artifacts, there is a compressed file (win.zip for Windows, mac.zip for Mac etc.). In order to run your snapshot, you have to unzip this archive (after which it will have the same name, minus the zip extension) then go into folder "bin". There you'll see two executables: idea.exe and idea64.exe, for 32 and 64 bit versions, respectively. Clicking on these runs your snapshot.
Adjusting contents of the files idea.exe.vmoptions and idea64.exe.vmoptions lets you set the VM parameters to suit yourself, typically people might want to give the VM more memory through the -Xmx value.
It seems straightforward:
To build the distribution archive of IntelliJ IDEA Community Edition, execute build.xml Ant build script in the root directory of the source code. The results of the build execution can be found at out/artifacts.
https://github.com/JetBrains/intellij-community#building
So download ant, and run ant in the directory that you have it stored in. Make sure to use the commandline to launch ant in order to make sure everything is working correctly.
Initially execute getPlugins.bat/sh, then:
Use update.bat/sh according to it's instructions
Or
Click on: Main Menu | Build | IntelliJ IDEA CE build
Copy content of intellij-community\out\deploy (lib, plugins folder) into existing IJ installation (sometimes it is better to delete existing folders if they contain older dependencies or when the installation was of Ultimate version)

Xcode custom shell scripts are slowing down the compiling time

Testing any changes to my Xcode project has become an exercise in patience whenever I build. After all the source files have compiled, I get the following message in the activity window at the top of Xcode:
"Running 3 of 3 Custom Shell Scripts"
I have not added any of my own custom shell scripts but I am using quite a few dependencies via Cocoapods and I am using 2 frameworks for the build environment, Crashlytics and Tapstream. Crashlytics requires you add a run script in the build phases, other than that I don't know where the other ones are coming from and they appear to be the bottleneck in my build time.
Can anyone enlighten me as to what is going on and how i possibly speed it up?
I can't enlighten you but I can tell you how I stopped mine from running. This also happened after installing Cocoapods. In my main project's Target, under Build Phases, I noticed two entries entitled Check Pods Manifest.lock and another called Copy Pods Resources.
Under both there was an unchecked option Run script only when installing. I checked both and at least for now my projects build and run fine without running the scripts.
This is kind of a crappy answer because I can't really give you any more information, and it might not even work for your case, so hopefully someone comes along and enlightens us.
POSSIBLE EXTERNAL BUNDLE ISSUES
So I just had a frustrating experience debugging an issue where a pod installed library's NSLocalized strings file weren't working. Turns out it was because I checked the option mentioned above. Pods-resources.sh, which had the lines to install the bundle, wasn't running in debug mode. It was only running when installing - of course! Something to watch out for.
More info in this question:
NSLocalizedStringFromTable not working in CocoaPod dependency
To fix the slow "Copy pods resources" problem I figured out a solution to only copy the resources if they haven't been copied before.
For this purpose we have to patch the *-resources.sh files that are created by cocoapods such that the copy procedure only happens if a generated file in the target directory doesn't exist (it is created upon first copy). As long as this target directory exists and includes this autogenerated file, the copy resources phase is skipped. This saves me about 30 seconds in my project (of course depends on your project size). To accomplish this do the following:
Create a patch file called 'copy_pod_resources_once.patch' in your project root dir with the following contents:
5a6,13
> NONCE_FILE="${TARGET_BUILD_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}/copyresources-done.nonce"
> if [ -f "$NONCE_FILE" ]; then
> echo "already copied resources"
> exit 0
> else
> touch "$NONCE_FILE"
> fi
>
In the Podfile for your project add the following post install hook:
post_install do |installer_representation|
system('find "./Pods/Target Support Files" -name "*-resources.sh" | xargs -I{} patch -p0 {} -i ./copy_pod_resources_once.patch')
<other post install stuff>
end
For me, it was Crashlytics. There were some outstanding changes, as Crashlytics does auto-updating of its files. I reset/removed them and rebuilt and got past it.
So the general answer may be to check any third party components and make sure they're working properly.
As Ramsel has said in this answer,
https://stackoverflow.com/a/21318086/1752988
I also went to Build Phases and cleared out all the possible links to PODs, after trying most of the other solutions and the three build issues shown regarding Pods were cleared out.
But then one file which was not list under the XCode Project navigator was missing, but they were in the Downloaded Git Zip folder! Obviously, I copied it and put into the XCode project and try running it runs cleanly! :)
I had a similar issue in my project (however not using Cocoapods). It ended up being an issue with an application external to Xcode (Spritebuilder) somehow holding onto a resource within my Xcode project when it crashed. I forced the non-xcode application to close and now the issue is gone
Check your project folder name have any space.Because space creates problem in directory path like "SRCROOT".I removed spaces and project run fine.
I've found that this happens to me frequently. Exact cause unknown, but appears to be switching between git branches that have differences in what pods are being used. In my case simply touching the Pods-xxx-Resources.sh shell script file causes it to speed back up.
Probably not going to work for you, but cleaning the project fixed it for me (Product -> Clean)

How do I use a dynamically load library in a command line utility? [duplicate]

using frameworks in a command line tool
Hey,
I've written a command line 'foundation tool' that uses the RegexKit.framework extensively. Everything works when run in Xcode but if I compile the release build and try to run it in Terminal I get the following error:
dyld: Library not loaded: #executable_path/../Frameworks/RegexKit.framework/Versions/A/RegexKit
Closer inspection reveals that the RegexKit.framework bundle is sat in the same directory as my executable file... I've done some research and I'm thinking that as command line tools don't use application bundles there's no where for Xcode to copy the framework to. So I'm guessing that I need to compile the framework as a static library and include it in my code... am I right? If so, how do I go about doing this? Is there anything I can do in Terminal to point to the framework externally?
Any help would be very greatly received, I've been banging my head against this for a few days now!
Thanks in advance,
Tom
So... What I did in the end was to recompile the framework with a different Installation Directory (in the Deployment section, under the Build tab in the Target's Info) - I set it to just #executable_path.
I then compiled the framework and replaced the one in my Utilitie's project, I also changed the Copy Files build phase to copy the framework to "Executables" rather than Frameworks.
The good news is that this fixes my original problem - but obviously the framework has to be in the same directory as the executable.
So this got me unstuck but I'd still love to know how to compile RegexKit.framework statically!
You shouldn't be installing the framework in the Executable folder of your bundle. It should be in the Frameworks folder. You need a Copy Files phase in your project that copies the framework and you need to set the Destination to "Frameworks". "Copy only when installing" should be unchecked.
When testing this, you should make sure you perform a clean build. I typically delete the build folder rather than using Xcode's Clean menu option since it's quicker and more comprehensive.
Also: you cannot statically link to a framework. If you want to statically link to something, it needs to be a static library so in this case, you'd need to hack about with RegexKit. Bear in mind that static libraries cannot contain resources, whereas Frameworks, being bundles, can.
