So if you need a GCC vs. Clang (vs. LLVM-GCC) switch, you _must_ check for Clang/LLVM first.


#if defined __clang__ /* The Clang frontend to LLVM (Clang) */
#define COMPILER "Clang"
#elif defined __llvm__ /* The GCC frontend to LLVM (LLVM-GCC) */
#define COMPILER "LLVM-GCC"
#elif defined __GNUC__ /* The GNU GCC compiler */
#define COMPILER "GCC"
#else
#define COMPILER "Unknown"
#endif

Unfortunately the maintainer had some trouble getting it to work with Leopard and the latest version is still very buggy.
Luckily someone from the Mozilla dev team fixed it and it works fine now in 10.5.

Thanks, John Justin!

btw: if you know a working solution for the trac ticket spam problem, say having a barrier for spam robots to create and comment tickets, please let me know! Having the ticket section disabled although it could be really helpful in collecting bugs is not very amusing.

I have to get Windows for developing purposes. One of my courses in the 4th semester require the AVR Studio IDE, which requires Windows XP. In “Embedded Processors” we are going to program an Atmel microcontroller to play the well known song “Frere Jacque”.

Luckily my university takes part in the MSDNAA developer program which gives you free access to operating systems, IDEs and other stuff from Microsoft. So here we go: Drop by at the office with a study attestation and get your login data. Then simply download the iso and burn it. “What, a 404kB exe file? What the hell?” Yes, they have their own installer, really! So what do you do with an exe file if you don’t own Windows? Fire up Darwine! Thanks to Mike, who builds Darwine snapshots regularly and offers them for download I now have the installer working and downloading a mysterious de_win_xp_pro_w_sp2.sdc file. “What the hell is sdc?” Next step in the installer is extracting the file, so let’s see if we get a burnable iso for BootCamp.

To be continued…

[continue]
Coming home from buying food I found my MacBook at full fan speed telling me that the start volume is full. Great! And WinHelper crashed. Even greater! But the installer is still open and tells me to click to install the product. So let’s see if we have an iso now.

Terminal showing directory with iso

Yey! An iso file! :) What a heck to just get Windows, no mentioning of installing and RUNNING it! Yak!

I recently found a nice review of some key features, no astonishing things IMHO, but still very useful.

I will hopefully get my hands on a Leopard Developer Preview soon to have some fun with CoreAnimation.. ;-)

It is developed by the author of Acquisition – the state-of-the-art filesharing app for Mac.

As I recognised it was from the same author as Acquisition thoughts were flashing into my mind:
- Did he really write a Bittorrent client from the scratch?
- No he wouldn’t. So which open source app did he choose to build upon then?

The answer was easy: Transmission. Of course all of you Q users know Transmission, it’s built right into Q for downloading new Guest PCs from FreeOSZoo. No mentioning of this neither on the product website nor on his blog. Only mentioning in the license agreement if you scroll down… “Xtorrent contains source code from libtransmission [...]“ and on the about pane:

No linking to the website of Transmission project, only a slight hint to what the software is based upon.. “[...] uses code from the libtransmission project.” – does he want to hide something? It seems indeed he wants to promote it as being his work, as writing on his blog entry announcing it: “Xtorrent is an advanced torrent client that has been in development for several months.”

He might be legally right, but one could ask if this is morally ok?! He could have just helped the Transmission team making a better Graphical User Interface (GUI) instead of making money of it. Although I have to admit that his GUI work is really nice, I don’t think many people will pay for it. Yes, it’s free for the moment as it is Beta software, but you know him, he will charge for it soon. :-/

What’s the moral? Use free Transmission Bittorrent client and support the original authors (Or, as to say with David’s words: “Support people, not corporations.”***

*** I’m not quite sure if I quote him right from within early Acquisition releases, correct me if I’m wrong.

Update: It seems that he uses libtransmission in Acquisition also.

Tools
Coding:
- SubEthaEdit – Collaborative text editor, great code highlighting
- XCode (of course)
- Terminal (my second home already, because we use a custom Makefile in Q)

Other Tools:
- Subversion – great version management
- Quicksilver – insanely great app launcher, along with the Developer Module even better for searching the Apple Developer Docs!
- Transmit – best FTP and SFTP client

Resources:
- Google search: cocoa …
- scotlandsoft
- Apple Developer Docs, of course
- CocoaDev.com
