Looking to compile software for the iPhone and iPod touch under Leopard? There are two approaches: You can download the latest toolchain svn from Google Code or you can use a legacy toolchain installer that just happens to work under Leopard.

Last night, Nicholas "Drudge" Penree pointed me towards a copy of Elliot Kroo's legacy 0.04 toolchain installer. This installer dates back to the "bad old days" of arm-apple-darwin-cc, before the better gcc version appeared. On the other hand, a working solution is a working solution so I'm not complaining.

After downloading, I mounted the disk image, ran the installer and then the "ooh shiny" program. To make this work, I had to install a copy of the iPhone disk as /usr/local/arm-apple-darwin/heavenly. There are various methods for getting a copy of your 1.1.1 disk floating around the net up to and including decrypting the install dmg from Apple. Google for details if you're unsure how to do this.

Next, since this is a VERY legacy install, I had to edit my .arm-cc-specs and fuss with them until they matched my system.

Finally, I grabbed a copy of my old libarmfp.dylib file and put everywhere I could think of until I got some existing projects to compile. I believe my final places to put it were /usr/local/arm-apple-darwin/heavenly/usr/lib/ and /usr/local/local.toolchain/heavenly/usr/lib but you'll have to hunt around on your own system to see where it fits. You'll be looking to put it in the same folder that has the working gcc_s_v6.1 library.

After this, I ended up with a working--albeit legacy--toolchain running under Leopard. I'll download and compile the new toolchain at some point but this gives me some much-appreciated breathing space before I need to do that.

Lots of drama in the iPhone development community since last night, and it all revolves around a decision that "lg," the developer of Installer.app, made to remove PXL from its list of installable applications. PXL is another package manager for iPhone (open source, while Installer.app is still free, but currently closed source), that works with either Breezy, iBrickr (for Windows), or any other PXL manager. A little while back, the PXL guys decided that the easiest way to get their packages onto the iPhone was to actually run through Installer.app, but lg, last night, apparently decided that he didn't want them doing that, and locked them out of the application.

And that, according to many iPhone developers, is not cool. The creators of NES.app, in response, have pulled their application from Installer.app completely, posting a notice on their site that "NES.app will no longer function from Installer.app or other third-party package installers that we believe are not trustworthy/secure. You will need to remove these tools to use NES.app."

TUAW spoke with drudge, the developer who originally wrote the package for PXL in Installer.app, and he makes it clear that this is a bad move for the iPhone community. "We need to grow and learn each step of the way," he told me in an email. "Releasing closed sourced apps at this stage in the game doesn't help anyone." But the problem, according to drudge, isn't that Installer.app is a closed source application. "The only problem is it is a centralized management system... meaning "lg" has the final say in what happens with any package." And when lg decides, as he did last night, that someone's out, everyone suffers.

lg has not commented on what happened yet, as far as we've heard. At this point, it sounds like everyone involved is trying to work towards a solution, and get the PXL package back in Installer.app (the alternative would be for PXL to create their own Installer.app type of program). As drudge also told us, "The community is only 2 months old so for developers to be taking sides... makes it harder on iPhone users and developers."

Thanks, drudge!

Update: They've reached a solution-- NullRiver (lg and the folks behind Installer.app) are going to create their own open source library for package management. Since PXL was created because Installer.app was closed source, another open source solution means PXL will likely not exist any longer.

Update2: Here's the latest.

Today developers Nicholas "Drudge" Penree and Shaun "Ste" Erickson have announced unlimited free Installer.app packaging for iPhone application developers. If Installer.app sounds familiar, you might recall that a few weeks back we posted about the Installer.app utility. Installer.app is an iPhone-based package manager from NullRiver.com. It allows you to download and update iPhone application packages over EDGE and WiFi connections directly from your iPhone home screen.

The problem with Installer.app packaging is that it's fussy and requires a lot of dotted-i's and crossed-t's and for many programmers who are busy improving their software, it's an extra step that can easily get overlooked. Enter Penree and Erickson. They are offering to bundle up your application and host it on either Penree's Conceited Software or Erickson's smxy.org.

These services are a big win for both the iPhone user base and the iPhone application developer community. They allow programmers to focus on their applications and the users to enjoy the fruits of their labors. Donations are welcome at both sites.

Both Penree and Erickson are considering expanding this service to include the new PXL/Breezy package management tool in the near future.
