In Xcode you can specify custom scripts to build your applications. I have a project which makes extensive use of these. For instance, one target builds the simulator versions (both 32bit and 64bit) and the ARM version as well as documentation and then bundles up the generated static library into a framework along with some other files
Running the above code can take a couple of minutes. Normally when you build, Xcode has a progress bar at the top of the screen. When you use these scripts it fills in a tiny amount and then stops there until your script completes.
It would be nice if there was a way to tell Xcode to update this progress bar? It doesn't have to be perfect, just a way of giving some feedback that something is happening and that the build process hasn't stalled.
Thanks!
It looks like you can use Bash in your custom build script. So why not do something like in the example linked, wherein for each build target you do
echo "building target name blare"
In fact, if you really want a progress bar, why not just use Bash to make one? See an example here.

I have developed (on a Mac) a small Flutter app to learn the technology. Now, I would like to build it and use it on Mac, Linux and Android. The few packages I have used claim compatibility with all systems.
So the first thing I did was to run flutter build macos. I indeed obtain an application under build/macos/Build/Products/Release/nameofmyapp.app. It seems this runs correctly, but it fails, for instance, loading data from a DB, which is the first thing it should do.
I have a few questions:
are there any other steps that I should take? I see a long guide about the release process, but to be frank I don't need or want any of that: I only want to use the app myself. Is there something else to do other than flutter build macos?
am I looking for the built app in the right place?
if I did everything correctly, could it be that I need to authorize the app to access to the file in some way? Should I manage this workflow myself, or is there a standard way to perform this action in Flutter?
Sorry for asking more than one question, but I am not sure whether what I am doing wrong is
the build process
where to look for the built app, or
(not) handling the app permissions.
EDIT
Following a suggestion by Madhavam, I tried flutter run --release. The result is identical to running the built application: nothing is loaded from the database, and no errors appear in the console.
To be clear, these are the libraries that are not working:
sqflite should load data from a database (in my Documents folder) but does not show anything
file picker cross should allow me to load data from a JSON file, but when I try this interaction, I an not shown any dialog to load a file
shared preferences should read some settings, but they all appear as null
In short, anything that has to do with interacting with external files or storage does not seem to work
Yup, you have to manage it yourself. Take a look at this package
:https://pub.dev/packages/permission_handler
If you're using Firebase then you probably need to add the release keys.
One thing too, if you face an error only in the release build then I recommend running the app with flutter run --release so that you can see the errors that are being thrown.
So it seems that this is related to the default being an app that runs in sandbox. Since I do not want to distribute the app, it was fine for me to disable this setting. Details are in this answer
Our current system is in .Net world and we are in the process of moving to FeF world (Angular) and we might keep the back end either in .net or change it to some flavor of JVM. We do not know about the server side yet but for sure, we will keep it as .Net for some time till we sort out the technology issues.
One thing I want to do during this time to do is build a CI system with language agnostic build tools. We use NAnt/MSBuild today. I would like to know as of now what are all active build tools out there, which can work with any language? I did find the following, but not sure how many are all active today. I am not trying to find which is best or not, all I want to know is the tool set and I will evaluate them based on our project requirements. I want to make sure I did not miss some build tool because I do not know the Java world.
Current list
Make
Rake
Gradle
BuildR
I did find this question but it is 5 years old.
Thanks
Interestingly if you look at the visual studio files in a text editor you will see that they are indeed build scripts. They are actually msbuild.
One of Xcode's most powerful features is it's Intellisense completion, which brings up a list of potential candidates as you type the name of a Foundation/Cocoa/UIKit API. I am very interested in MacRuby, PyObjC, or the more recent RubyMotion, however without code completion these tools seem like more trouble than they're worth.
Is there any code completion feature (not necessarily Intellisense) for any of the three technologies above, for any text editor (but preferably for Vim or Xcode)? Bonus points for an IDE solution which allows for building and running the application in a single command (like Xcode's Run button).
It's my understanding that Xcode 4 dropped support for MacRuby/PyObjC, so Intellisense is no longer available. Should I install Xcode 3 alongside Xcode 4 for the code completion? How is everyone else doing it (surely you guys use some form of code completion -- I can't believe anyone can remember all the classes in Foundation/Cocoa/UIKit)?
RubyMotion comes with vi ctag support. Run rake ctags to create them.
FWIW, there is a Code completion package for Sublime Text 2, which can also be installed via the package manager of the Sublime text.
And it seems to work rather well for me.
Yes, you can give yourself Vim code completion by running $ rake ctags in the root directory of your RubyMotion app. To take that a step further, use a shell script to generate ctags automatically every time you create a new RubyMotion app. This article shows how to build such a script:

I have custom frameworks in my app bundle for WebKit, WebCore, and JavaScriptCore. I would like all other frameworks that depend on the system versions of WebKit, WebCore, or JavaScriptCore to use my custom versions also. For instance my custom version of Webkit loads private system frameworks that in turn depend on the system version of WebKit. This means both my WebKit and the system WebKit get loaded, and usually a crash happens shortly after.
The way I understand this should be done, is to set the DYLD_FRAMEWORK_PATH environmental variable before your app bundle begins execution (Search order for loading frameworks can be found here: http://code.google.com/p/macdependency/wiki/SearchPaths). You can set environmental variables in code with setenv, but it won't take effect for the currently running process. I would have to re-launch the process again for it to take effect. I would like to avoid this too.
So my question is what is the best way to set the DYLD_FRAMEWORK_PATH before the execution of the my app bundle? This has to work in a release app bundle too. Is there a way to run a script whenever someone clicks on my app bundle before the executable starts running. Or is there any other suggestions out there?
Thanks in advance.
Jeff Wolski has the right idea by referring directly to Apple's documentation on the subject. This thread also provides excellent advice on how to get that going in Xcode, including corner cases associated with alternative methods of specification (for example, by using ~/.bash_profile directly for your user).
My reason for chiming in is you also asked for a script that might be able to assist you (and a bounty provider appears to have the same issue). It turns out Webkit references such a script in its documentation, which you might want to pick apart from the applicable Webkit source code. This should give you additional guidance on how, at least according to the developers, you should do this properly.
Best of luck with your project(s).
I would recommend environment.plist or the LSEnvironment key in the info.plist. Check out the link below.
https://developer.apple.com/library/mac/#documentation/MacOSX/Conceptual/BPRuntimeConfig/Articles/EnvironmentVars.html
WebKit currently has a script to do this for you, called run-webkit-app. See http://trac.webkit.org/browser/trunk/Tools/Scripts/run-webkit-app
Newer versions of ld understand the -dyld_env flag, which inserts a LC_DYLD_ENVIRONMENT load command into the binary (and as such applies essentially as early as possible in app execution). Perhaps adding -Wl,-dyld_env,DYLD_FRAMEWORK_PATH=/folder/encosing/WebKit/and/related/frameworks to your compiler flags might do what you want?
I know that in a normal NDK build, the C++ libraries are built and packed into an apk file. But how can I automate this in Eclipse? I have tried following http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/ to run the native-activity sample that came with the NDK, and it ended up not working. Even after I got past most of the reference errors via including, nothing happens when I run it as an Android Application (with a Motorola phone plugged in).
I have looked around quite a bit about this and am still stuck, so I'm open to suggestions at this point. Thanks!
(Please keep in mind that I'm using MinGW/MSys on Windows 7, mostly for running scripts with bash)
I've just decided to go with an Ubuntu VM and use that, and with some tweaking it seems to be working the way it should. I used a combination of http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/ and http://developer.android.com/sdk/ndk/overview.html#native-activity to get everything set up. Also a very important note, go to C/C++ General -> Code Analysis -> Launching in your Eclipse project settings and disable both of those options for any native activities you make. I'm not sure if there's a good way to set the libs and includes up for it to work, but currently live bug checking screws things up in the NDK, and I can currently build successfully without it. Plus it'll still mark errors in red after a failed build, so you shouldn't be completely in the middle of nowhere when finding errors.
