Do you have XCode installed into a different location? Your CMAKE_OSX_SYSROOT looks different from mine:

CMAKE_OSX_SYSROOT:PATH=/Developer/SDKs/MacOSX10.6.sdk

​This post indicates someone encountering a similar problem with XCode 3.2.1 not installed into the default location. I think the catch will be trying to tell the CMake port to look for the XCode development tools in a non-standard location. Do you have all the SDKs installed into /Developer/XCode3.2.1?

[piergiuseppe.fogli@…]

First of all thanks for your reply!

Yes, XCode is installed in a different directory, /Developer/Xcode3.2.1 . Setting CMAKE_OSX_SYSROOT to the exact location:

CMAKE_OSX_SYSROOT:PATH=/Developer/Xcode3.2.1/SDKs/MacOSX10.6.sdk

solved the problem!

Thank you very much again!

So the catch is twofold ...

1. Can MacPorts easily detect that XCode 3.2.1 is installed into a different location?
2. How can the CMake Portfile indicate this location when configuring the port?

Replying to css@…:

That's the developer_dir variable.

Has duplicate #25484.

During the configure phase, provide an init file to the cmake bootstrap that specifies CMAKE_OSX_SYSROOT as the developer_dir.

The bug is fixed upstream (see patch in issue page) and will be rolled in 2.8.5:

Any confirmation that this may now be closed with cmake 2.8.5?
