[webkit-dev] Building QtWebKit on Mac

[Brian Ellis]

Hi all,

I've been haunting #webkit and #qtwebkit for a while with this  
problem, but it seems to be some kind of tricky configuration issue,  
so I thought I might have more luck asking here.

I'm trying to build QtWebKit on a Mac (running 10.5.6) from an  
unmodified WebKit trunk working copy.  I have Qt 4.5 installed in the  
usual location ('which qmake' returns '/usr/bin/qmake'), and obviously  
I have Xcode and friends installed in /Developer as well.

When I run the following command from the root of the WebKit directory:

/WebKitTools/Scripts/build-webkit --qt --release

I get the following output:

> phoenix/Source/experimental/thirdparty/WebKit/WebKitTools/Scripts/

Now, it looks to me like there's some kind of misconfiguration  
somewhere in the environment, because that first message it prints  
implies that we're passing an unexpectedly empty string to chdir(),  
which might be the case if (for example) an environment variable that  
was supposed to be set was unset...  and the rest of the output looks  
like qmake is generating the wrong kind of makefiles.

Here's all the environment variables that are currently set on my  
machine (minus a few irrelevant ones like PATH and PS1):

I'm hoping that someone reading this will have some idea what might be  
going wrong.  I'm told a couple of you build QtWebKit on Mac from time  
to time, so it would be very helpful to know what your configurations  
look like.  I should also mention that I've been having this problem  
for over a month now, so it's definitely not related to any changes  
that went in in the past few weeks.

Thanks!
