trouble installing capybara-webkit on Windows8 - windows

Question

I am following the tutorial:https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#gentoo-linux
and get stuck at step 11, where I get an error saying Command 'qmake -spec win32-g++ CONFIG+=test' not avalable.
I have no idea how to solve this, and I did add Qt/4.8.6/bin in the path.

Answer 1

I just spent a while getting this to work. I found that the QT environment/system variables were not set up correctly when QT installed. Short version: I found a problem with my Qt install: although it was in my path and qmake would run (I could do qmake -v and get output), that wasn't enough. The variables that Qt uses for paths (e.g. QT_INSTALL_HEADERS, etc.) were not correct. I had to run the Qt configuration program configure.exe. That correctly set all of the Qt variables and all was fixed.
I figured that it must be some kind of issue on my end, since I saw that others have installed it successfully. I went through each of the components required to verify the installation and setup -- and found the problem. I've been able to compile gems just fine using just DevKit, so suspected that it had something to do with Qt. (and it did) Here's what I did to check and verify each component:
DevKit: made sure it was installed in the ruby versions needed, and
verified that it worked:
checked '/devkit/config.yml' to make sure it listed each of different installed ruby versions, and then
re-ran the DevKit install script (ruby dk.rb install) to be sure that DevKit had installed the right files into each of those ruby versions.
I verified that DevKit was working using the recommendation on the DevKit page [https://github.com/oneclick/rubyinstaller/wiki/Development-Kit]: I installed the json gem. It was able to build the native version so that verified that DevKit was installed and working properly.
Qt: I downloaded the Qt files (I used 4.8.5; glad to know I can upgrade). I ran the .exe file downloaded to install them.
made sure that Qt directories were in my path (see the list below).
made sure that the environment variable QMAKESPEC was defined:QMAKESPEC=win32-g++
made the edits to the qmake.conf file (the 'Frommel workaround') as described on https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#windows
ran qmake -version to verify that qmake would run and to verify the version
ran qmake -query to verify the set-up for Qt. This is where I saw the problem with my Qt install: the paths were all wrong.
ran the Qt configure.exe program to fully configure my Qt install. This was the key step. (I thought that the initial installation program would have configured things, but obviously it didn't.) Running this will build all of the demos and examples and so takes a while. But when it completed, all was well.
ran qmake -query to verify that the Qt settings and been fixed and were correct.
System path and ENV variables: the following need to be in your path:
[devkit dir] (ex: C:\rubys\devkit-mingw64-32-4.7.2)
[devkit dir]\mingw\bin;
[devkit dir]\bin;
[qt dir] (ex: C:\Qt\qt-4.8.5-x86-mingw)
[qt dir]\bin;
[ruby version]\bin (ex: C:\rubys\ruby-2.0.0-p598-i386-mingw32\bin)
[ruby version]\lib\ruby\gems\
define the environment (system) variable QMAKESPEC=win32-g++ (If you don't give qmake/Qt the specification about which system to build for, it will look for this ENV.)
I know it's been a while since you posted your question, so hopefully you've solved it. If not, try these steps and see if they help.
