Hello,

It looks like qt4-mac-devel fails to build on Lion (10.7.2) with XCode 4.2. Log file is attached. Variant options used are:

+quartz +universal -examples -demos +framework -debug

Try cleaning the port and rebuilding using clang:

sudo port clean qt4-mac-devel
sudo port install qt4-mac-devel configure.compiler=clang

Build attempt with clang

[michaelld (Michael Dickens)]

qt4-mac and clang don't mix well. clang has some features that are documented but not implemented, e.g., using pre-compiled headers as well as LIBRARY_PATH and CPATH. So, llvm-gcc is the way to go. I haven't seen this particular issue before, and my 10.7 box is away for the day. Hopefully I'll have it back tomorrow & can test building qt4-mac-devel myself.

This issue should be fIxed in r94241. Please do the following

sudo port clean qt4-mac-devel
sudo port selfupdate

and then try to install or upgrade qt4-mac (not qt4-mac-devel). I'm closing this ticket, since it now refers to an old version of qt4-mac. Please open a new ticket if this issue persists with the new qt4-mac.
