I'm trying to install webkit for Capybara, using the information provided here, but I'm getting an error.
Following the instructions I have tried to change the qmake.conf file in the Qt installation directory but I couldn't find the QMAKE_IDC parameter and I don't know where the following values should be placed:
QMAKE_RCC = $$[QT_INSTALL_BINS]$${DIR_SEPARATOR}rcc$${EXE_SUFFIX}
QMAKE_LFLAGS = -static-libgcc -static-libstdc++
The following error is what I got:
C:\Users\Deepzster\Desktop\app\app>gem install capybara-webkit
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing capybara-webkit:

Command 'qmake -spec win32-g++ ' not available
Makefile not found
I had the same problem. I had installed the latest version of Qt, which is version 5.3. I looked up the instructions on https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit, and one of the instructions is to modify the qmake.conf file, and the edits are to be made after "the line beginning with QMAKE_IDC". However, this line wasn't available in my qmake.conf file.
Therefore, I installed the version stated in the instructions, which is version 4.8.5. Here's the link - http://download.qt-project.org/archive/qt/4.8/4.8.5/. I downloaded qt-win-opensource-4.8.5-mingw.exe (I'm on a Windows 7 64-bit machine).
The qmake.conf file in this version does have the line beginning with QMAKE_IDC, so I could edit it as required. I then followed the rest of the instructions up to step 10 on the link (I also tried step 11, but I got a 'make failed' error). I then went to the directory containing my Gemfile and entered
gem install capybara-webkit
and the installation was successful.
