I need to create an iOS app that reads and writes Excel .xlsx formatted files. Using XlsxReaderWriter I have tried countless times to link following instructions in the README.md file, but have never succeeded. It says that older systems can use libz.dylib instead of libz.tbd, but I can only find libz.tbd and newer versions up to libz.1.2.8.tbd when compiling on Xcode 10. Perhaps there are issues with newer versions of libz that are undocumented.
I've run out of ways to link, install, and run an app with XlsxReaderWriter and wonder if anyone could share a simple app in Objective-C that would show what a successful installation looks like. Endless thanks will follow. Thank you.

i'm having some issues getting modules to work on my app - I keep on getting told that the requested module cannot be found.
It is entirely possible that i'm not installing the modules correctly - so, for the purposes of this question:
Once i've downloaded the zip file from git hub using the green "download" button, what do i do to import the module into my project? Not how do i tell tiapp.xml to use the module - just what do i do to install it?
Can you please run through using the facebook module found at https://github.com/appcelerator-modules/ti.facebook
thanks!
Inside the zip file of the download you'll see there is a folder called modules. This is the same folder that is in your root of the project.
So, an iOS module should be installed in the /modules/iphone folder. Once added, you can add Facebook to your app like this:
<module platform="iphone">facebook</module>
If you want to specify a version you can do so like this:
<module platform="iphone" version="1.1.0>facebook</module>
note: I made up the version number
You can also add it through the tiapp editor in Appcelerator studio, although it doesn't always seem to find the module. This might be a bug in studio though, usually it works great.
HMMMM
Two main issues here, one directly relating, the other less so.
Issue 1
The link i gave to get the codebase from github is wrong - well, it gets the codebase, but not in a form that can be used as a module. It is, in fact, the uncompiled version.
Versions for download can be found here.
So that takes care of issue one, what about
Issue 2
The latest version for use is a bit broken. Seems someone (from the appcelerator team???) decided to make the latest 6.0.1 release have a minsdk of the (at this time) as-yet-unreleased version 6.0.0, and sets the apiversion to 3.
This breaks the current release of 5.5.1, so for anyone reading this prior to 6.0.0 for appcelerator, you will want to use this release version.
I'm looking at using Tesseract to do some work with PDF files, and so I want to use the library rather than an external executable.
I started by downloading the full Tesseract source and looking at building that. Sadly the standard sources don't have any means to build on a non-Linux platform, in my case Windows. There are methods for doing so, and I looked at those.
Firstly the VS2008 build doesn't. I'm aware that it need Leptonica, but I figured I'd tackle that afterwards and just tried to build the existing code. Fails with "fatal error C1083: Cannot open include file: 'allheaders.h': No such file or directory". Nothing to do with Leptonica at this stage, it simply doesn't work.
Even if I were able to get past that, I'd have to build Leptonica, and that requires using GNU tools and therefore an installation of Cygwin, so I gave up. I Have a MingW instatllation, (I've never managed to get Cygwin to work in a usable fashion) but I'm not keen enough to mess with such a complicated and fragile build.
So I decided I'd just use the pre-built binaries which some kind soul creates. Downloaded that from code.google.com. Now I need to look into using the code, so the next obvious step is the Tesseract API example, which states it requires "tesseract-ocr-3.02.02-win32-lib-include-dirs.zip", no problem, because I already have that now.
No real clue as to where the API example wants the files to be placed, but a little messing about gets them in appropriate locations. Press build and "fatal error C1083: Cannot open include file: 'allheaders.h': No such file or directory", just like trying to build Tesseract from source.....
And indeed there is no such file.
So, where is this file ?
I also struggled some time ago to make it works under windows and then I found this git repository : https://github.com/charlesw/tesseract-vs2012
It includes all needed extern library (because Tesseract need Leptonica, but Leptonica also need extern library to handle the different image format) and is also working great with vs 2013.
OK so now I see that allheaders.h is part of Leptonica. Still leaves me wondering why the Tesseract pre-built library requires that I have Leptonica available, I would have expected that to be built-in, I guess it isn't.
i want to use FANN (fast artificial neural network) with Xcode
i googled for a way how to get the FANN and install it in Xcode but i did not find a result
please guys does anyone know from where can i download FANN library and use it with Xcode
thanks
Go to http://leenissen.dk. Here you will find the source code you can download from sourceforge.com and install instructions for Cmake on the command line. Just follow the instructions and you will see several static libraries were included. Now all you will have to do is add the library you want to use and the include (.h) files to your Xcode project. From here the example code from the FANN website should work.
Note that when you reference the FANN .h files to your projects files you must use include and not import. I ran into this problem myself.
There was a issue with exporting a code signed application using Xcode. I was able to find a solution after playing around with code signing.
I decided to try manually code signing my app with instructions from http://www.digicert.com/code-signing/mac-os-codesign-tool.htm. This did not work. However the code signing tool pointed me to a problem with libfann.2.2.0.dylib. So I checked if libfann.2.2.0.dylib was code signed and it was not. When I saw this I thought I would try code signing libfann.2.2.0.dylib with my developer ID and re-importing it into my project. This strategy worked and I was able to export a developer ID signed version of my application.
I just upgraded my Xcode, now when I try to open my project, I get this error:
Project /Users/xxx/xxxx/xxxxx/xxxxxx/xxxxxxxx.xcodeproj cannot be opened: PBXContainerItemProxy (xxxxxxxxxxxxxxxxx) is missing a containerPortal key
I have searched the web and stackoverflow, but cannot get anything relevent to come up at all regarding this.
I do have Three20 as part of my project, I don't know if that matters. I just upgraded to xcode 4.4.1
Thanks for any insight.
-D
the project icon which we see i.e projectname.xcodeproj, is actually a directory, you do this
1. in terminal do cd yourproject.xcodeproj
2.ls
3.vi project.pbxproj
4. scroll down till /* Begin PBXContainerItemProxy section */
5.there you will see all sections check for the section which is missing a portal key edit it and save it :wq it will work
in image if you see the first section is missing container portal key.just pic it from other section and replace it..
it will work :D see this link
Now I should start with that I do not know the actual error, never seen it before, but I did find a reference to a "PBXContainerProxy"-error in this post (As soon as I add a project to XCode 4.0.2 it crashes) and thought you might try the solutions from there?
"Apparently this is due to the new version of XCodeProjects. I found a
work around by pre-compiling the library that was causing the issue
and then using the linker to link to the .a file. I also had to copy
the .a library into the DerivedData path.
The real solution was to remove the project and replace it with an
updated project for the new version of XCode."
Hope that helps somewhat :)
Never saw that error either, but if you're upgrading directly from XCode 3.X I'd suggest you to go to https://developer.apple.com/downloads/index.action?name=Xcode
and download/install a previous version of Xcode somewhere else. (You can have several different copies installed on your machine, just google it if you don't know how but just remember to use xcode-select to pick the one you want to use). Repeat with all the versions back to 4.0.1 until (hopefully) it works. I know it's tedious but it might help.
If it does, validate the project settings and try to open it with 4.4.1. That should work.
Good luck
I downloaded the Doomclassic Source Code and wanted to have a look at it. First I wanted to compile it to see if it actually works. So I followed the instructions and copied the .wad files into the base folder, openend the project and hit compile. Aside from the over 300 warnings and the missing files (mostly Images, which I mostly fixed) I have a strange error during teh compile phase and google is no help at all.
It says:
/Users/tobias/Library/Developer/Xcode/DerivedData/Doom-egfadrxunamfwjdsdaylawcyppkc/Build/Intermediates/Doom.build/Debug-iphonesimulator/Doom.build/Script-435F41A90F532CA300887552.sh: line 3: /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/DevToolsCore.framework/Resources/pbxcp: No such file or directory
When I check my Xcode.app the only framework in the PrivateFrameworks folder is IDEBundleInjection.framework
I also had a look at the script:
!/bin/sh -x
PBXCP=${DEVELOPER_DIR}/Library/PrivateFrameworks/DevToolsCore.framework/Resources/pbxcp
${PBXCP} -exclude .svn "${PROJECT_DIR}/../../base" "${BUILT_PRODUCTS_DIR}/${UNLOCALIZED_RESOURCES_FOLDER_PATH}/"
So it seems that I need this framework - but even with google I couldn't find it and I wouldn't know how to integrate it into the Xcode App? I have updated Xcode to 4.4 just now but it's still the same error.
Does anyone has any advice please?
The pbxcp command was removed from XCode 4.4, so you'll have to find a replacement for it. See this mailing list thread to alternatives to the command.
