Universal Binary #7

If you are still using 10.5 as the base SDK for Vienna, I'd really appreciate it if you compiled it as a Universal Binary! By setting the architecture flag to 32_64_universal (as I recall) will make a full build compatible with all PowerPC and Intel architectures.

It is based on the 10.6 SDK, but should run on PowerPC machines (10.5).

And as far as I know, it is also the only 64 bits binary currently available... Seems significantly faster on my config.

The base SDK provides the minimum version that the compiled application will work on. For 10.5 compatibility, the SDK must be changed to 10.5.

Funny, I am on Snow Leopard, but I just had the same issue with Ansani's version here http://forums.cocoaforge.com/viewtopic.php?f=18&t=23979&p=132136

I (naïvely ?) thought the "MacOS X deployment target" value should handle this...

For maximum compatibility, it is probably safer to statically link a few libraries... I'll have a look at this.

I got it again:

Dyld Error Message:

It looks to me like Vienna either needs to change the minimum requirements for libcurl to version 5 or include a copy of the current version of libcurl.

The Vienna code is using libcurl only once, to parse a date... (see XMLParser.m)

I moved the call to a separate framework, built using the 10.5 SDK. This way, it does not require libcurl version 6 anymore.

I am wondering anyway if there isn't a more efficient and robust enough way to parse a string representing a date... For instance ISO boredzo's 8601 date formatter https://bitbucket.org/boredzo/iso-8601-parser-unparser

Weird, I still get the same error.

I downloaded the source zip and found that the baseSDK is 10.6 while the deployment target is 10.5. I'm trying a build now in Xcode 3.1.3.

I got 223 build errors related to missing GUI delegates. ;p

Oh, this was the master branch. What branch should I build to test this?

@barijaona Ok, I grabbed that and I still can't build it. Note: I did find that you need to set the deployment target to 10.5 and the SDK for the dev and release to 10.5.

As for why I can't build it, either I am missing a piece or converting from newer Xcode to my older version is causing an issue. Could you please save a copy of the .xcodeproj file in 3.1 compatible format? Perhaps name it Vienna-xcode3.1.xcodeproj?


barijaona commented Jan 16, 2012

I don't have XCode 3.1, but I modified it to be 3.2.6 compatible. I just uploaded a binary at https://github.com/barijaona/vienna-rss/downloads

That version launches! :D

Customize toolbar does not work though.

Hi guys!
I'm currently work on this issue.
I tested a preliminary release on my 10.6.x mac and app launches without any problem.

I'll do some other tests and I plan to release short.

(Of course I mean the google_reader_support branch.

The official master currently supports universal building (tested on Snow Leopard with Xcode 3.2.6).

@CyberSkull : if you have a Leopard machine, please test...
