ios compilation problems

[skipper3k]

I downloaded the new ios api 1.0.1 framework for smartfoxserver 2X, imported it to my project as shown in instructions, but I get a linker error :

Code: Select all

Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_SmartFoxiPhoneClient", referenced from:
      objc-class-ref in MySFS.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am using the SmartfoxiPhoneClient object just like in the older ios examples I could find, which used to work with RC1 version of the SFS2X.

I tried to change the instantiation of the smartfox object from the SmartFoxiPhoneClient object to SmartFox2XClient. When I do that my project compiles, but the app crashes uppon connecting with no error just (gdb) :

Code: Select all

2012-02-22 10:31:11.262 MySFSExample[10241:707] [SFS - INFO]sending handshake request: isReconnection : NO
(gdb) 

any ideas what I am doing wrong ?

You can get a full backtrace after the crash by entering "bt" after the "(gdb):".

Try and see if you can find out what's happening there, otherwise, post the results and we'll have a look.

I guess I'm missing SBJson dependencies :

Code: Select all

2012-02-22 12:41:18.862 MySFSExample[10676:707] [SFS - INFO]sending handshake request: isReconnection : NO
(gdb) bt
#0  0x000260dc in -[SBJsonWriter setHumanReadable:] ()
#1  0x00026378 in -[SBJsonWriter setHumanReadable:] ()
(gdb) 

I'll try to look into that.

Thanks for the tip.

I can't seem to get it to work even with the new sbjson library.

Any suggestions ?

Please read the client API setup instructions in the documentation, as we changed the import statement.

Hi Bax.

I have setup the API according to the instructions. My app compiles and runs. I also se in the smartfoxserver log, that a session was created. But when the response comes back to the ios client it crashes, with the error I posted previously.

Now I am looking for what I might have missed.

To elaborate my settings :
I have pretty much the default server.xml configuration, except for the ip part. Protocol mode is binary.
My ios config.xml looks like this:

Code: Select all

<SmartFoxConfig>
	<ip> some ip adress </ip>
	<port>9933</port>
	<blueBoxIpAddress> some ip adress </blueBoxIpAddress>
	<blueBoxPort>8080</blueBoxPort>
	<smartConnect>true</smartConnect>
	<httpPort>8080</httpPort>
	<httpPollSpeed>750</httpPollSpeed>
	<zone>BuddyMessanger</zone>
</SmartFoxConfig>

Android client example connects to the server, so does the BuddyMessanger flash example.

Any suggestions ?

Ok, the previous error is irrelevant...

What really happens is this error: SIGSYS

I created a completely new project, with only smartfox ios api imported, just like explained in documentation.
I created a Smartfox2XClient property. And I only call this code :

Code: Select all

    smartFox = [[SmartFox2XClient alloc] initSmartFoxWithDebugMode:NO delegate:self];
    [smartFox loadConfig:@"config.xml" connectOnSuccess:YES];

SIGSYS happens right after connection attempt and before the connection attempt returns to its delegate method. I should also mention if the ip is wrong, the app does not stop, but the onConnection delegation method returns not connected. I have the latest ios 1.0.1 framework and the latest Smartfox 2X server.

config.xml is the same as I mentioned above.

Can you tell me what XCode version you are using? Which SDK? and which target?

Also, make sure ARC is turned off - this is a Non-ARC release.

[skipper3k]

Xcode version 4.2, Build 4D199.

Automatic reference counting is disabled. Arhitecture with the SIGSYS error was set to armv6. On armv7 I get a slightly different error, this one : EXC_BAD_INSTRUCTION
Base SDK is iOS 5.0
Apple LLVM compiler 3.0
Device target is set to iPhone only
Deployment target is set to iOS 5.0.

tnx, lk

[A51Integrated]

OK. It looks as if there are some settings that may need to be adjusted - it's just hard to tell which ones without access to your XCode.

Base SDK -> Latest iOS (iOS 5.0)
Supported Platforms -> iphonesimulator iphoneos
Valid Architectures -> armv6 armv7
iOS Deployment Target -> iOS 5.0
Other Linker Flags -> -lxml2 -lz -ObjC
Header Search Paths -> /usr/include/libxml2

Make sure these frameworks are imported:
SFS2XAPI.framework
CFNEtwork.framework
UIKit.framework
Foundation.framework
CoreGraphics.framework

Clean the project and run.

[skipper3k]

Sorry.. I still get EXC_BAD_INSTRUCTION on @autoreleasepool in AppDelegate.

I uploaded this simple test app. If you have any time, please take a look at it, maybe it will be more clear what is wrong with my app.

Are there any new ios examples available for the new release ?

[A51Integrated]

I just tried your sample app and it compiles and connects successfully for me. The only thing I did was change the config.xml to:

Code: Select all

<SmartFoxConfig>
    <ip>127.0.0.1</ip>
    <port>9933</port>
    <udpHost>127.0.0.1</udpHost>
    <udpPort>9934</udpPort>
    <zone>simpleChat</zone>
    <debug>true</debug>
    <blueBoxIpAddress>127.0.0.1</blueBoxIpAddress>
    <blueBoxPort>9339</blueBoxPort>
    <smartConnect>true</smartConnect>
    <httpPort>8080</httpPort>
    <httpPollSpeed>750</httpPollSpeed>
    <rawProtocolSeparator>%</rawProtocolSeparator>
</SmartFoxConfig>

I copy pasted the config file, and changed the ip and udpHost to my server ip 192.168.1.181 - its no secret, its a local dev machine.
Still get the same error. I'm posting a screenshot, and my server.xml configuration, because I don't know where to look for the problem anymore.

pretty much a standard server.xml config. Maybe there is a setting here I am missing.

Really hard to say, but from your project settings, look at "Framework Search Paths". You have some other entries in there. Make sure there is only one "$(SRCROOT)/.." and it's recursive (checked).

Again, the project is working fine for. I literally unzipped changed the config and ran it. The only warning I got was an unknown search path (above). SO remove those - the inherited one as well and let me know what happens.

Hi,

just ran with proposed options deleted. Still get the same error. As does my coworker. We both have iPhone 4 devices, running 5.0.1 (9A405) - offical latest ios version. It also crashes on an iPad and a 3G S with the same ios version. I'll try to find a device with a lower ios version and post the result.

I also run this app in the simulator and it worked. It works on a flash app and in an android example on a device. It must be something with this particula

What device are you running on ?
