Hi Bryan,

On Tuesday 19 November 2013 08:57:40 Bryan Evenson wrote:

I'm on poky/dylan-9.0.1 and I've created a layer for a separate
open source project to include in my image. The layer is at
https://github.com/evensonbryan/meta-bacnet for those of you who

want

to try and duplicate my results. Just add this layer to your
setup and build the recipe "bacnet-stack".

I have a very odd build issue. The first time I build the

recipe,

the

build fails during the compile step. However, if I then build

the

recipe again, the compile completes without errors. For example:

1. bitbake -c clean bacnet-stack
2. bitbake bacnet-stack (compile fails) 3. bitbake bacnet-stack
(compile succeeds, rest of image packaging works)

Additionally, the following order compiles without error:
1. bitbake -c clean bacnet-stack
2. bitbake -c devshell bacnet-stack 3. (from devshell) make all
(compile succeeds)

This project is divided into a static library and multiple demo
applications. The static library needs to be built first, and
then the demo applications include the static library in their
build. I suspect I have an issue with either populating the
static library or the related include files in the sysroot which
causes the demo applications to fail to build the first time but

work the second.

However, I can't figure out how to fix the issue. Any pointers

on

what is setup wrong with this recipe?

From bacnet-stack.inc:

do_install () {
install -d ${D}${bindir} ${D}${datadir} ${D}${libdir} >

${STAGING_INCDIR}/${PN}

...
install -m 0644 ${S}/include/* ${STAGING_INCDIR}/${PN} }

Don't poke files directly into the sysroot like this. Install the
headers to ${D}${incdir} instead, and they will be staged to the
sysroot for you.

I made the suggested change and I'm still having the same build

issue.

I pulled the applicable lines from the compile log when I get the

failure.

If I'm reading this right, the build of the static library fails
because it doesn't know how to build bip-init.o, but immediately

after

the static library build fails then bip-init.o gets built. Any

thoughts on what could be wrong?

Thanks,
Bryan

Try disabling parallel build : add to your recipe PARALLEL_MAKE = ""

That worked! I'm able to build the clean package the first time now. Although I am getting a QA warning about all the include files being installed but not shipped. This is one part that has always confused me to no end on how to handle static libraries. I know the include files need to make it to sysroot for other applications which use the static library to build properly. However, they don't need to be in the final device image. So do the include files need to be included in the FILES_${PN}-staticdev list and in do_install, or should they be listed in a separate step?

Thanks,
Bryan

Another option: create 2 recipes: one to build and install library and
another to build demo application. Make demo application dependent on
library.

Cheers,
Michael

Paul
