[joeblew99]

i have gotten it all working on OSX and windows.
Now trying out on Linux.

Its a clean ubuntu inside a vm.

Here we go::

# get gcc 
sudo apt-get install gcc

gcc is already the newest version (4:5.3.1-1ubuntu1).
gcc set to manually installed.

# check its there !!

[andlabs]

It is trying to rebuild package runtime. Did you make any changes to the Go source?

[joeblew99]

@andlabs

I did not make any changes to the Go source of github.com/andlabs/ui.
I have a clean machine with gcc installed and just did a go get on github.com/andlabs/ui

i tried it again this morning, and got the same thing.

Not sure whats going on...

Maybe its because my gcc is too old ?

[joeblew99]

I would love to be able to help you.

To help you I would need to learn how to take the code in the libui report and compile it into statics for this report I am guessing.

If you feel like it do have time to help on this.
