Native code compile fails on Mint 17.3 MATE #142

Closed dwilde1 closed 8 years ago

dwilde1 commented 8 years ago

Mint is a derivative of Ubuntu 14.04 LTS. Gem installed as sudo gem install qtbindings. Intent is to compile for QT4 although there are some Qt5 packages installed. Ruby 2.2.5 compiled from Source. Qt libraries installed as .deb packages from Synaptic. gem_make.out.txt

It looks like you have a ruby installation in /opt/ruby-2.2.5 which is conflicting with your built against copy in /usr/local/lib/ruby.

It's the same installation. The sources are built in /opt/ruby and it puts the gem repos in /usr/local/lib/ruby. The binary goes in /usr/local/bin. It's been this way in every ruby since they included gem in the distro.

I'll try cleaning out the /opt/ruby binariy.

That's after removing every SMOKE module...

From the readme:

Ruby installed and in your path (Ruby must be compiled with --enable-shared on all platforms and with --with-gcc=clang on OSX)

It looks like your ruby was not compiled with --enable-shared

Yay, got it.

Thank you for your patience, Jason! Although I started with FreeBSD in 1992, the admonition to 'RTFM' has inevitably given way to expectations that things will 'just work'. I've been in this biz long enough to know the complexities behind packages as complex as marrying Qt and Ruby.

My next project is marrying Ruby to the Open Dynamics Engine through libFFI, and you've helped me immensely by helping me to prepare for my GUI once I get the acceleration simulator flying. (literally; I'm making a drone automated flight path optimizer)

I hope Ruby and Qt serve you well. Good luck!
