NML - Large sets: one vehicle per file?

[audigex]

So I tried adding pil as well as pillow using the following

Code: Select all

sudo pip install pil --allow-external pil --allow-unverified pil

And it works!

So to note my procedure in case anyone comes across similar issues, I think this was the way I got it working:

1) Install python
2) Install pip using easy_install

Code: Select all

sudo easy_install pip

3) Instally ply using easy_install

Code: Select all

sudo easy_install ply

4) Install the development tools

Code: Select all

xcode-select --install

5) Install pil AND pillow

Code: Select all

sudo pip install pil --allow-external pil --allow-unverified pil

Code: Select all

sudo pip install pillow

6) Install nmlc

Code: Select all

sudo pip install nmlc

Thanks for the help planetmaker - especially with my not-exactly-clear explanations of the issues/errors

it clearly says you're missing some header file. so you did not install all required libraries.

Installing PIL and Pillow may come back to bite you. Pillow is just an alternative setup of PIL, so you now have two copies of essentially the same thing. (There's even a 'PIL' directory /inside/ pillow.) When I was investigating the same problem, I came across several Pillow devs worrying online about how having both PIL and Pillow was going to result in some people installing both, having it appear to work, then have it all break horribly later. They were against this.

It clearly says it, but I didn't clearly understand it we in the open source word sometimes forget that not everybody is familiar with the same things as we are. I'm reasonably technical, but I don't generally use python or need to install libraries for my coding work, so they aren't things I look out for when following instructions

The article says that

pip
If you are familiar with python and pip then you can just use
pip install nml
This will install the required dependancies.

That nml install worked first time, so I assumed that it would have installed the required dependencies. Once I got errors it became clear that this wasn't the case so I had to look into installing them separately.

I got to the bottom of it, as you can see above - but it definitely didn't work after installing pillow successfully, and did after installing pil. I don't know how/why that worked like that, I'll play around later seeing if I can reproduce it.

What nmlc version are you using?
nml r2113 ( http://dev.openttdcoop.org/projects/nml ... de26b64471 ) changed the "import Image" line to also try "from PIL import Image", which is the recommended form to use for Pillow.

The first attempt was using the hg repository
hg clone http://hg.openttdcoop.org/nml nml

The second attempt using whatever version pip pulls

I don't think I tried the hg version once I'd installed pil+pillow+ply

I'm pretty sure you want to use 0.3.0 or a newer nightly. I'm not sure what pip will install. And nmlc --version would tell you.

Anyhow, if it works for you now, it will be easy to use the version from the hg repository. Just add that to your path. Using it that way makes it very easy to update.

I'm now running:

0.3.0.r5161:86932569ca7d from 2014-02-17
Library versions encountered:
PIL: 1.1.7
PLY: 3.4

I removed nml with pip, cloned it into ~/nml, ran

Code: Select all

sudo python setup.py install
and added /Users/jon/nml to the path using ~/.profile (which OSX apparently does look for, even if it's not created, which confused me)

[code]export PATH=/Users/jon/nml:$PATH

Perfect

I have to run nmlc with sudo, and it complains about

not trusting file /Users/jon/nml/.hg/hgrc from untrusted user jon, group staff

Which presumably is a users/permissions thing, but it seems to compile the grf anyway. Or at least, it creates the file - I've not got anything exciting in it yet, so I can't test if it's working properly

[Eddi]

you should probably solve that permission issue... don't run programs as root when there's no reason for it.

[audigex]

It's only a dev box for open source and hobby stuff - if someone wants to steal the contents of some github public repositories then they can go ahead

On the other hand I have solved it - the install created a file parsetab.py, which was owned by root, in the nml folder... I've changed the owner to me and it works perfectly
