OSX 10.11 qt55 qmake error

[Judahmeek]

Having successfully installed qt55,...

brew tap homebrew/versions
brew install qt55
brew link --force qt55
which qmake # returns correct directory

...I get the following error when attempting to bundle capybara-webkit: Command 'qmake LIBS\ \+\=\ -L/usr/local/opt/libyaml/lib\ -L/usr/local/opt/readline/lib\ -L/usr/local/opt/libksba/lib\ -L/usr/local/opt/openssl/lib' failed

I've checked /usr/local/opt/ and libyaml, readline, libska, and openssl are all there. Running qmake LIBS\ \+\=\ -L/usr/local/opt/libyaml/lib\ -L/usr/local/opt/readline/lib\ -L/usr/local/opt/libksba/lib\ -L/usr/local/opt/openssl/lib directly from the terminal opens help like there's some sort of syntax error.

Anyone run into a similar issue?

Is there any other output when you try gem install capybara-webkit? Do you know which version you're trying to install?

Here is all the error output:

An error occurred while installing capybara-webkit (1.11.1), and
Bundler cannot continue.
Make sure that \'gem install capybara-webkit -v '1.11.1'\' succeeds before
bundling.

Backticks inside quote changed to \'. Also, I have already accepted the Xcode license agreement.

@jferris This proved to be a duplication of https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#xcode-80 (except that I've got XCode 8.0 on OS X El Capitan now and the path was slightly different: [Qt_install_folder]/[Qt_version]/mkspecs/features/default_pre.prf)

If I hadn't screwed up my grep the first time I looked for that line, I could have saved us both some trouble.

Edit: thanks for reminding me to update my link, @seanlinsley

[jferris]

Glad to hear you've solved it. Installing Qt can be rough.

[seanlinsley]

I also ran into this problem.

The wiki link above is no longer valid. Here's what it is now: https://github.com/thoughtbot/capybara-webkit/wiki/Installing-Qt-and-compiling-capybara-webkit#xcode-80

[RemyMaucourt]

@Judahmeek I have the exact same problem, and I can't find the solution you mention in the link. Can you elaborate a little?

[Judahmeek]

Yeah, link rot is an issue with wiki pages. Fortunately, we have the revision history. Here is a link to the missing section.

@aripollak is there any particular reason you removed that section when you updated the wiki?

[aripollak]

Yeah, I thought that issue was fixed with newer versions of the Homebrew package. Is that not the case?

[vassilevsky]

I have just upgraded to macOS High Sierra 10.13.1 and Command Line Tools 9.1 and I have the same problem 💖

[seanlinsley]

@vassilevsky it looks like you just need to accept the Xcode license. You can do that with:

sudo xcode-select -r

[vassilevsky]

I have installed and launched Xcode and then it worked.

[yunixon]

cd /Applications/Xcode.app/Contents/Developer/usr/bin/
sudo ln -s xcodebuild xcrun

If you're on MacOS and have installed QT 5.5+ with Brew, make sure that the binary is linked correctly. You can tell it is pointing to the qmake binary correctly by running:

$ which qmake

and seeing that it returns something like /usr/local/opt/qt@5.5/bin/qmake. If it doesn't return anything, it needs to be linked. To link it run this:

$ echo 'export PATH="$(brew --prefix qt@5.5)/bin:$PATH"' >> ~/.bashrc
