Emscripten Support

2013-05-23T15:49:11Z

Hi Everyone,
I'm brand new to this list but am interested in the Cocoatron project
because I'm attempting to port some Objective-C code to the web using
Emscripten. I've been working in my own Cocoatron repo and have been able
to successfully compile Foundation + dependencies into Javascript using my

project cleanup and relocation of install directories

2013-05-17T23:49:56Z

Hi,
I've gone through and cleaned up the projects a fair bit. The most
significant ramification is that the final frameworks are now in <working
copy directory>/system/<target-trip le> instead of /Developer/Cocotron/1.0/.
This allows one to have multiple clones on the same system without install
directory interference.

CoreFoundation's lib?

2013-05-09T20:35:19Z

When I build the CoreFoundation project (Windows target), no lib is created
for it. Is that to be expected? A bug/limitation? Something I'm not doing
right?
$ find ./ -type f -name \*.a
.//AppKit.framework/libAppKit. a
.//Cocoa.framework/libCocoa.a
.//CommonCrypto.framework/libC ommonCrypto.a
.//CoreData.framework/libCoreD ata.a

JSON library

2013-05-09T10:45:44Z

Hello
I've tried building a project that was using JSONKit
[link] with no success, but I have not
managed to make it link cleanly.
Any one has any recommendation for a JSON that will be nice to cocotron and
me?
Thanks for your time.

printf not working?

2013-04-21T18:47:53Z

Hello
I'm new to cocotron and to objective-c, so please be patient if I'm missing
something obvious.
My printf statement is not working on Windows, and I haven't got a clue.
Writing to a file does work.
int main(int argc, const char * argv[])
{
NSInitializeProcess(argc,argv) ;
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

best way to organize clones

2013-03-29T14:36:23Z

Hi Chris,
I see you have merged several clones but not mine. I know you prefer
looking at the cumulative diff instead of at the individual changesets. And
I guess you might not be happy with the "improvements" I made, even though
I consider the "fixes" both important and trivial.
Would it be better if I divided the changes into two separate branches, one

error: expected method to write dictionary element not found on object of type 'NSMutableDictionary *

2013-03-27T20:44:38Z

I have been trying to port an Objective-C program from Apple Xcode 4.5.2
which compiles perfectly to Linux CentOS 6.4 using Cocotron. I am using
the GNUstep runtime with clang 3.3. I am getting hundreds of "expected
method to write..." errors. For example:

Problems with CFPropertyListCreateFromXMLData, CFPropertyListCreateXMLData methods in CoreFoundation.

2013-03-24T17:38:48Z

I try to port MobileDeviceAccess project to Windows from MAC using
Cocotron, and now I have some troubles. This library
uses CFPropertyListCreateFromXMLDat a, CFPropertyListCreateXMLData methods,
which are declared in CFPropertyList.h. So, there are no errors during
compiling. But, there are two errors during linking: undefined reference to

Foundation-Linux i386 barfs on build- pthread and NSZombieObject?

Hi all,
Been having great success with Cocotron,building stuff for windows, want to
try Linux. Foundation keeps giving an error on build, NSZombieObject can't
find <pthread.h> and subsequent errors because of this. pthread.h is in the
Windows build headers but not in the Linux build ones. Am I missing

SIGSEGV in objc_lookup_msg.m - Linux x86-64

2013-02-02T19:43:11Z

Hey everyone!
I'm working on cross-compiling my Cocoa application for a Linux x86-64
platform (Redhat 6) from OS X 10.8 and Xcode 4.6. I spent the better part
of several days getting the Cocoa frameworks built and once I successfully
built my application I'm now running into issues executing on the Linux

Accelerate Framework

Thanks

Text is white when drawn into a lock-focused NSImage

2012-12-15T23:37:54Z

Hello,
If I lockFocus on an NSImage and call drawRect: on an NSTextView, the text
that gets drawn is white and fuzzy instead of black and crisp. Does anyone
know why this would happen and how to work around or fix it?
Best,

Compile error when using apple libobjc.dll as runtime

2012-10-16T00:09:44Z

Hi, guys
I using apple objective-c binary precompiled libobjc.dll as runtime.
And then using clang+llvm+gcc at mingw32 x86 toolchain.

When ld.exe link to .dll some error shown.

I think it's about gcc options -fgnu-runtime and -fnext-runtime.

Cocotron + Linux build + Clang + GNUstep ObjC2

Hello,

what's the current status of building on Linux with clang and GNUstep's
ObjC2 runtime?

I've started working on creating a robust build system with CMake and it's
coming along very quickly and nicely, though I'll have to write some
assembly code for functions not available in libobjc2 (such as

Hello,
I'm using Cocotron to build a server-side component of an iPhone app. A big

etc), uploaded to the server, and sent back to the phone having been
processed. For testing purposes, I'm just sending back the data unmodified

Can Cocotron (and related tools) be used entirely within Windows environment ?

2012-10-09T05:59:33Z

Can Cocotron (and related tools) be used on Windows to build Xcode source
into a target than can be executed on Windows ?
(this would be useful for development / testing, since my access to Mac is
more limited than my access to Windows at this time)
Thanks for your time !!!

Can Cocotron (and related tools) be used to build/test Xcode all on Windows ?

2012-10-09T05:53:32Z

Can Cocotron (and related tools) be used on Windows to build Xcode source
into a target that can be run on Windows ?
Why do I ask ?
I can get more time on PC/Windows than on Mac/OSX. So it would be handy to
be able to do a significant amount of development/test on Windows...

Crash during font enumeration on Windows 8 64-bit

2012-10-03T16:34:55Z

Hi,
I've successfully been using Cocotron for my app on Windows XP and Windows
7 (32 and 64 bit) for the past year or so. However, when testing the exact
same app on Windows 8 RTM build (64-bit), I'm finding that it crashes on
startup.
I tracked the crash down to the GDI font enumeration code in Onyx2D

Using gcc 4.3.6 with Cocotron ok?

2012-09-29T10:46:50Z

In the course of analyzing some weird crashes I produced a new compiler by
merging the Cocotron changes for gcc 4.3.1 into gcc 4.3.6. Luckily all
conflicts could be resolved trivially. In the end, the cause of the crashes
was unrelated (-mstackrealign appears to corrupt the stack in MinGW
Objective-C++ code). Given the number of bugs fixed in gcc 4.3.6 I now

Protocol Declaration Errors

2012-09-22T21:48:17Z

Is anyone else getting these errors when compiling using protocols?
Can anyone help?
It looks like none of the protocol declarations can be found, even though
they are inside of AppKit.h

Cocotron with Xcode 4.5 + blocks

2012-09-19T00:23:00Z

Does anyone have cocotron working with block support in Xcode 4.5?
I'm toying with the idea of trying to hook up 4.6 gcc that has block
support or figuring out why I can't install the llvm from tobias's(sp?)
branch -- but even with this, I'm worried about what other roadblocks I
might run into.
Thanks in advance!

What is the current state of blocks?

2012-09-19T00:04:25Z

I understand that in the mainline, blocks aren't supported.
I tried following the directions for one of the forks that support branches
with LLVM, but it failed to install.
Does anyone have this working with Xcode 4.5 to compile to Windows with
blocks supported?

Can't build Cocoa for Windows under Xcode 4.4 because of error in Foundation-FreeBSD-i386

2012-09-17T19:32:59Z

I've previously had Cocotron running on my PowerPC Mac running OS X 10.5.
Now I'm trying to get it up and running on an Intel Mac running 10.7/Xcode
4.4.1. I've got CDT installed and I can compile Foundation.xcodeproj and
AppKit.xcodeproj, but when I try to compile Cocoa, I get the error
"Pthread.h: No such file or directory" under the Foundation-FreeBSD-i386

bugs

2012-09-10T15:56:46Z

While porting our App into cocotron, we figured out a few issues which are worth fixing:

[NSNumber numberWithDouble:somevalue] seems to always return nil.
[NSNumber numberWithInt:someintvalue] however works.

I couldn't figure out where the error occurs but it looks like the generic NSNumber object gets allocated instead of the subclassed NSNumber_double or something like that.

NSTextDelegate / NSTextViewDelegate missing in Cocotron?

2012-09-08T01:37:36Z

I'm attempting to get some code working on Cocotron that contains protocols
conforming to NSTextViewDelegate; on compile it complained that
NSTextViewDelegate did not exist. So I looked into Cocotron's AppKit
implementation, and noticed that NSTextView.h does not contain a protocol,
but has an @interface declaration with a category like this:

NSAutorelease pool loop

2012-08-23T22:17:15Z

Hi,

We finally got a Foundation library for linux working under 64bit. However we run into new problems in multithreading.
The app I'm trying to port is fully multi threaded. After spawning off a thread it creates an autorelease pool for that specific thread.
This however seems to cause a problem which raises an exception. And the string formatting to print the exception then raises an exception again. This loops at infinitum...

Xcode 4.4 with embedded platforms

2012-08-27T14:36:18Z

The relentless churn in the Xcode toolchain is getting frustrating. Trying
to get Cocotron to play nice with Xcode 4.4 (with the embedded platforms in
the app bundle) and not getting very far. My theory is Xcode app binary
knows about the acceptible platforms and Cocotron is not one of them.
Has anyone had any success getting Cocotron to play nice with Xcode 4.4?

Problems with Linux arm setup

the same issues using an 'alternate' linux ARM target. My libc target
environment is using libc-2.15.so, but I see the same errors building

'Linux arm' on OSX Mountain Lion

2012-08-21T02:30:48Z

Hello all,
I've been heads down for a few days setting up the Cocotron environment
on my MacBook running OSX Mountain Lion. My main porting target (short
term) is ARM, with my main platforms being iOS/MacOSX. I have
successfully built "Linux i386" and windows platforms, with little to no
issues beyond getting the 'PlatformInterfaces' directory setup correctly.

Does Cocotron support complex tree controls?

2012-05-25T19:52:33Z

Hi Cocotronians,
I need a tree control in my application with custom node types (specific
editing behavior), node images and drag-and-drop support. I started with
NSTreeController but I figured out it is not implemented in Cocotron. Not a
big problem as it wouldn't have helped with the custom node types anyway.

Cocotron + Xcode 4.3 + Lion

2012-05-24T16:16:32Z

Trying to move our development environment forward here after a successful
time with Xcode3.
I've installed the latest InstallCDT and that's made the compiler settings
happy in Xcode 4.3 - but I'm
not seeing Cocotron as an available SDK so things are unhappy.
Anyone have a clue on what the trick is to make that available?
