[build.py] problem with waf

wxPython Dev
1

Last night I checkout the current wxPhoenix and wxWidgets as submodule
and tried to build it on my Lubuntu 14.04.2.
Before starting the build command I checked with apt-get the existence
of the needed librarys/packages described in README.rst.
The build command

"python3 ./build.py build"

Caused the error below. I don't understand because I don't know what
waf is. There is no manpage available about it on my system.
The "--help" of the downloaded waf-binary in Phoenix/bin describe a lot
of options but didn't tell about what it really is.

It is a tool like make or other recipe driven software build tools, except it uses Python code to define the build rules. See Phoenix/wscript.

From the README:
"""
The following commands are required to be able to build Phoenix from scratch. In other words, from a pristine source tree with none of the generated code present yet. They can be run individually or you can specify all of them on a single command line, in the order given. Once a command has succeded in one run of build.py there is no need to run that command again in a later run, unless you've changed something which that command has the responsibility to process.

  * dox: ...
  * etg: ...
  * sip: ...
  * build: ...
"""

You need to run at least the other 3 build.py commands shown above before the build command.

Nice to know. Thx for description.

From the README:
[..]

Maybe it depends on my bad english but I could understand your
README.rst that way, that I have to run the commands in order. For me
it was not clear enough.

And shouldn't the "build" part of the build.py check if the other three
commands where run successfull before?

"build" work over one hour on my machine and then gave me a cryptic
error. This doesn't help it just waste time and energy and lower
motivation of people how want to contribute to wxP.
