Note that because 10.10 is pre-release software we may not be able to help you with it until it is released.

CMake can be compiled on Yosemite here.

You must install Xcode 6 DP in order to have the 10.10 SDK available. You must set xcode-select accordinghly.

You must install Xcode 6 DP in order to have the 10.10 SDK available. You must set xcode-select accordinghly.

In addition to using xcode-select, I had to set CMAKE_OSX_SYSROOT=/Applications/Xcode6-Beta4.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/. Works for me now.

I Installed the beta4 of Xcode 6 and did setup the env. var and ran xcode-select but still it didn't work. what could I have done wrong?

[borodiychuk (Andriy Borodiychuk)]

Just run "sudo port clean cmake", and then install it again.

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #44505.

[hkroger@…]

Why was this ticket closed. That #44505 was closed as a duplicate?

[neverpanic (Clemens Lang)]

Probably because there is a solution outlined above?

[odslabs@…]

Thanks ryandesign for including me in this.

I was able to get cmake to install by downloading and installing xcode 6 from ​https://developer.apple.com/xcode/downloads/ then:

port clean cmake
xcode-select -s /Applications/Xcode6-Beta4.app/Contents/Developer/
port upgrade outdated

cmake configured, built and installed without a problem but then I hit:
