How-to allow Mac OS X’s Gatekeeper to run an unsigned application

Leave a reply

Eclipse sandboxed by Mac OS X Gatekeeper.

Eclipse sandboxed by Mac OS X Gatekeeper.

After I recently reinstalled my MacBook Air with Mac OS X Mavericks, I encountered for the first time Gatekeeper – the sandbox, that won’t allow to run applications from unverified sources to improve Mac OS X security. However that also excludes the commonly used IDE Eclipse.

Problem: Eclipse (or other application) won’t launch in Mac OS X Mavericks.

Solution: delete extended quarantine attribute – which probably Safari or Finder added after the download. Enter the following command in the Terminal to allow Eclipse to launch.

$ xattr -d com.apple.quarantine eclipse.app

This way you can leave the sandbox in place and only add exceptions for applications, that you cannot live without. For further information on and graphical configuration options of Gatekeeper check out this Ars Technica article.

xerces-c-src_2_6_0 on Mac OS X Tiger

Issue

When I tried to compile Xerces-C++ Version 2.6.0 from source on Mac OS X Tiger 10.4.2 with gcc-4.0.0 the compiler complained:

MacOSUnicodeConverter.cpp:78: error: 'static' may not be used when defining 
(as opposed to declaring) a static data member
MacOSUnicodeConverter.cpp:84: error: 'static' may not be used when defining 
(as opposed to declaring) a static data member
make[2]: *** [MacOSUnicodeConverter.o] Error 1
make[1]: *** [transcoders] Error 2
make: *** [Util] Error 2

Solution

The solution is easy, just delete the word static in the source code manually and build again or use this patch:

xerces-c-src_2_6_0-tiger.diff

Patch instructions

Download the Xerces-C++ source distribution from [1].

The sources contained in my case version 2.6.0.

Extract sources and apply patch:

tar xzf xerces-c-current.tar.gz
cd xerces-c-src_2_6_0
patch -p1 <../xerces-c-src_2_6_0-tiger.diff

Please make sure that the paths are adjusted to your system. Follow the official build instructions Building Xerces-C++ from the Mac OS X command line at [2] afterwards.

Qt-mac-free-3.3.4 on Mac OS X Tiger

Hint

If you don’t need specifically qt-mac-free-3.3.4 but any 3.3.x would do it, you might want to check out Trolltech’s recently published Version 3.3.5. If you ever wondered – like me – where you can still download the 3.3.x branch have a look at

ftp://ftp.trolltech.com/qt/source/

It seems that you can’t find any more download links for 3.3.x at Trolltech’s webpage.

Issue

When I tried to compile Qt for Mac 3.3.4 from source on Max OS X Tiger 10.4.2 with gcc-4.0.0 the compiler complained:

Additionally with both compilers gcc 4.0 and gcc 3.3 linking an application against qt-mac-free-3.3.4 resulted in warning messages like the following, because Mac OS X Tiger comes with additional dynamic library handling functions which now conflict with qt:

Solution

Apply the following patch:

qt-mac-free-3.3.4-tiger.diff

Patch instructions

Extract sources and apply patch:

tar xjf qt-mac-free-3.3.4.tar.bz2
cd qt-mac-free-3.3.4
patch -p1 <../qt-mac-free-3.3.4-tiger.diff

Please make sure that the paths are adjusted to your system. Follow the official build instructions afterwards. After applying the little patch qt-mac-free-3.3.4 and applications linked to it should build fine with gcc 4.0 and gcc 3.3.
