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.
This happens if I use a read-only source tree:
~/tmp/out-of-tree > pwd
/home/EB/sebastian_h/tmp/out-of-tree
~/tmp/out-of-tree > ~/src/rtems/waf --top $HOME/src/rtems-read-only
--out $PWD/build configure --rtems-config $PWD/config.ini
Setting top to :
/home/EB/sebastian_h/src/rtems-read-only
Setting out to :
/home/EB/sebastian_h/tmp/out-of-tree/build

This error can be fixed with the "--no-lock-in-top --no-lock-in-run"
options. The
CWD /home/EB/sebastian_h/src/rtems-source-builder/tmp is not under
/home/EB/sebastian_h/src/rtems, forcing --targets=* (run distclean?)
warning can be avoided using "--targets=*". So, with a couple of extra
options it seems to be possible to do an out of tree build with
read-only sources.
