Yosemite and Valgrind

Valerio's svn workflow will download every branch which is time and resource consuming. A better procedure is to download just the trunk:

svn co svn://svn.valgrind.org/valgrind/trunk valgrind
cd valgrind
./autogen.sh
./configure
make
make install

Whilst it may have been the case in past OS X release cycles that Valgrind took a period of time before achieving reasonable feature support, basic OS X 10.10 support is already available in Valgrind trunk due to significant work on pre-release Yosemite.

From the mailing list:

There has been some effort recently to improve Valgrind's support for Yosemite. If you develop on Mac OS, you might like to try out the trunk (svn co svn://svn.valgrind.org/valgrind/trunk) and report any breakage you get. Support for Yosemite is good enough that at least one large graphical application (Firefox) runs OK. Support for the previous release, 10.9 (Mavericks), is also substantially improved.

Note that the work has targetted 64 bit processes only. 32 bit might work, and probably better on Mavericks, but I suspect it will be increasingly problematic on Yosemite due to Valgrind's 32 bit x86 instruction set support not having progressed passed SSSE3.

Full disclosure: I'm one of the new Valgrind developers who contributed patches to support OS X 10.10

As there's no stable release that supports Yosemite, you can install the latest development version with

brew install --HEAD valgrind
