UPX 3.04 with patches for MacOSX

The latest version of UPX (3.04) contained a bug that prevented it from handling correctly MacOSX binaries. A correction was committed to the source tree. I have compiled a version of UPX 3.04 with this correction and you can download the corresponding universal binaries from the following links :

UPX 3.03 for MacOSX

The latest version of UPX (3.03) has just arrived and it adds support for the LZMA compression. This can enhance the overall compression ration but it's new and it's less tested. So, I decided to provide two binaries for this version : one with the LZMA support and one without. As for the previous release, these binaries will run under Tiger (10.4) , PPC and Intel alike, and Leopard (10.5). Here we go :

UPX universal binary for Mac OS X

As the buzz is mounting on the Mac OS X platform these days, I decided to buy one and start hacking. On the Windows and Linux platforms, I'm used to compress all my binaries using UPX, thus saving space and bandwidth. Unfortunately, when I tried to download a version of it for Mac OS X, I couldn't find a single link, even on the official web site. So, I decided to compile a version myself. The task was not straightforward but I was able to build a universal binary Mac OS X 10.4 and 10.5. It should work on 10.3 but I didn't test it. The result can be downloaded from the link below. I hope this will help. http://www.idrix.fr/Root/MacOSX/upx-3.02-universal-macosx.tar.gz
