OSX install with Homebrew updated to 3.6.0

[dinkypumpkin]

For any Mac users who may be interested, the Homebrew (http://mxcl.github.com/homebrew/) installation formula for DCMTK has been updated to 3.6.0. It also now supports installation of dev libs and/or building from git HEAD.

Remove old version if installed:

Code: Select all

brew rm dcmtk

Update Homebrew formulae:

Code: Select all

brew update

To install utilities and man pages:

Code: Select all

brew install dcmtk

To install everything (incl. dev libs and HTML docs):

Code: Select all

brew install dcmtk --install-all

To install everything from HEAD build:

Code: Select all

brew install dcmtk --HEAD --install-all

Thanks for the hint and your work

By the way, you do not needed to disable threads any more on Mac OS X when building 3.6.0. This wasfixed before the 3.6.0 release.

Also, third party libraries like libtiff, libxml, libpng and so on are not required by DCMTK. You can use it greatly without. The best is to leave the 3rd party library detection on automatic mode, i.e. ./configure will find out itself whether it has the libraries available on the system. Of course, if you found that this detection does not work well for libtiff and your dependency hint is just fixing this, then you can ignore this comment (but may document that in the homebrew "package" file, otherwise people will wonder).

Best regards,
Michael

Thanks for the tip re: --disable-threads on OS X. I missed that change in the final INSTALL document for 3.6.0. I'll submit a change to the Homebrew formula.

Whoever wrote the original formula decided that a Homebrew build of DCMTK should include everything (including libtiff), as do the the versions from MacPorts and Fink. That seems appropriate since someone installing from Homebrew (or other package manager) is not likely to be interested in refining the build configuration. OS X already supplies libssl, libz, libxml, and libpng, so those will always be detected and enabled during configuration. OS X also supplies libwrap, though it will not work without patching DCMTK, so it will always be detected but disabled during configuration. Since libtiff is not already available in OS X, it would have been added as an explicit dependency.

Unfortunately, Homebrew doesn't really support optional dependencies. If you'd prefer libtiff to be removed as a default dependency for Homebrew DCMTK, just let me know and I'll take it out and add some appropriate caveats to the formula. I don't have an opinion either way, so I'm happy to follow your lead on this.

Hi,

thanks for the feedback. In this case, requiring libtiff is just fine and I would keep it as you suggest.

We will also look into libwrap -- I was not aware that it does not work for Mac OS X.

Best regards,
Michael

The problem with libwrap is that in OS X <tcpd.h> does not have ANSI C function prototypes needed for C++. I don't use it anymore, but all I did was copy the approach used by MySQL. See this thread.
