Command 'gcc' failed with exit status 1

Dear all,

I've been trying to install Vatic in my computer (OS X), but I always get the attached error when introducing to the terminal the command ./vatic-install.sh

Besides, as you can see, there are many issues regarding the enum class. Could someone help me with that?

Thank you very much,

Hi,

This is a problem with the newer version of Cython. Downgrade to cython 0.20 and try again. Cheers

[arbues6]

Thanks @natanielruiz !

[Timebutt]

I am getting the exact same error, but downgrading Cython to version 0.20 doesn't help me.

timebutt@DESKTOP-1M0N4G1:/mnt/c/Users/ibcn/Documents/pyvision$ sudo pip freeze

This is the error I am getting:

Any idea what may be causing my problem?

[maartenvds]

I can confirm, same error after downgrading Cython to 0.20

[Timebutt]

I ended up using the Docker container and get the VATIC tool running that way.

[maartenvds]

Thanks, that worked for me too

[ahmedmostafa]

Hi Guys, Sorry I am new to this tool & environment, I am stuck at the same error and I am not able to overcome, could you please till me how to install the Docker container ?

[wecacuee]

After you downgrade to Cython=0.20, make sure you clean the pyvision directory so that the Cython generated files are regenerated.
