Can variables `top` and `out` in the example there be manipulated to
do want you want?
Yes, the --top and --out options works somehow, but I get a warning
like this:
Waf: Entering directory
`/home/EB/sebastian_h/src/rtems-source-builder/tmp/build/sparc/erc32'
CWD /home/EB/sebastian_h/src/rtems-source-builder/tmp is not under
/home/EB/sebastian_h/src/rtems, forcing --targets=* (run distclean?)
Also the documentation says "Though Waf may be called from any folder
containing a /wscript/ file,", so I am not sure if this is really
supported what I am doing.
What works is something like this:
./waf configure --out $PWD/tmp/xxx/build
called from the source tree. However, this has some side-effects.
1. A .waf* directory is created in the source tree (this is an issue
with a read-only source tree).
2. Waf somehow remembers this configuration. You can call "./waf" to
build it. So, there must be some hidden state in the source tree. This
is not really an out of tree build. You cannot have multiple independent
build trees.
