wiki: SimultaneousVariantBuilds doesn't work with scons4?

[karlp]

I'm not sure how to address this, but the example given on: https://github.com/SCons/scons/wiki/SimultaneousVariantBuilds doesn't work with scons v4.0.1 (at least)

It simply emits:

karlp@strem:~/src/scons-toys$ scons
scons: Reading SConscript files ...

scons: *** Two environments with different actions were specified for the same target: hello.o
(action 1: gcc -o hello.o -c -O2 hello.c)
(action 2: gcc -o hello.o -c -g hello.c)
File "/home/karlp/src/scons-toys/src/SConscript", line 2, in <module>
karlp@strem:~/src/scons-toys$ scons -v

It didn't seem appropriate to make an "issue" for this though, so I've made it a discussion...

nevermind, I fixed it after reading something on the cookbook and I can just edit the page directly with a fix :)

thanks for the update! wikis do have a tendency to "bitrot"... build_dir was renamed to variant_dir a very long time ago (15+ years) but that doesn't mean all pages got updated. It's only recently that the old deprecated name was actually removed.
