Hello again,
the more elegant way would be:
DEPS_DIRS := src
$(DEPS_DIRS):
$(MKDIR) $@
test_capnpc_middleman: $(test_capnpc_inputs) | $(DEPS_DIRS)
test_capnpc_middleman: capnp$(EXEEXT) capnpc-c++$(EXEEXT)
$(test_capnpc_inputs) | $(DEPS_DIRS)
Cheers
Eric

Betreff: AW: [capnproto] build w/ yocto
Hello Kenton,
many thanks for the fast reply and check-in. - I will give it a try and get
back to you.
Three things are really near to my heart:
1.) Please abstract the usage of commands
- mkdir -> $(MKDIR)
- touch -> $(TOUCH)
- make -> $(MAKE)
- ...
This is really necessary since e.g. Yocto brings it very own
environment including native tools along. Actually every build system does.
Using bare commands is like the 80's hackers did.
We just committed a fix to U-Boot recently abstracting "python".
There should then be a file defining the commands such as:
MKDIR ?= mkdir -p
TOUCH ?= touch
MAKE ?= make
This also gives you the opportunity to define certain parameters along
w/ the command. Please note the question mark. This enables any other make
environment to override the commands.
Apart, capnproto has got two build systems. - Which one shall be
actually used and why are there two of it?
2.) The second thing I would like to address is that there should be
branches for Yocto. E.g. "krogoth" and "morty". We have already the openjdk
maintainer convinced that this makes definitely sense.
3.) Third, will you push the recipes to [1]? - I might remove the hack
w/ the "src" directory before.
Many thanks
Eric

Hi Eric,
I don't know why the behavior would differ on your system (maybe automake
changed?), but I imagine this should fix it:
https://github.com/sandstorm-io/capnproto/commit/5f20b5cc1032df29d830409433c7d7a0c71266e5
Let me know if that helps.

Hello,
w/ Yocto's krogoth branch everything works fine. With Yocto's morty branch the
"src" directory in the "build" directory is missing and "capnp compile"
complains about that. Just creating a "src" directory is enough. Then
everything works fine.
What would be the proper solution to fix this? Is there a configure option
available?
We use capnproto 0.6.0 release. Please find the Yocto recipes attached. - Maybe
someone may post it on [1].
Cheers
Eric
