Hi Max,
I use the following lines in my local.conf file (on kirkstone). Maybe that this
is not
optimal as it may cause silent side effects in case the original values for
BUILDSDK_OPTIMIZATION/_CFLAGS/_CXXFALGS will change same day.
# Build -nativesdk packages with debug info (required for generating -dbg/-src
packages)
# BUILDSDK_OPTIMIZATION is based on BUILD_OPTIMIZATION in bitbake.conf
BUILDSDK_OPTIMIZATION = "${@oe.utils.vartrue('DEBUG_BUILD', '-Og', '-O2', d)}
-g -feliminate-unused-debug-types -pipe"
BUILDSDK_CFLAGS = "${BUILDSDK_CPPFLAGS} ${BUILDSDK_OPTIMIZATION}
${DEBUG_PREFIX_MAP}"
BUILDSDK_CXXFLAGS = "${BUILDSDK_CFLAGS}"
Additionally I have to manually select all available nativesdk-*-dbg/-src
packages in my
nativesdk-packagegroup-sdk-host.bbappend file. Unfortunately these packages are
not added
automatically to my SDK image (SDKIMAGE_FEATURES only applies for target
packages, not for
nativesdk packages). Maybe you'll find a better solution for that.
In my project I have added BBCLASSEXTEND="nativesdk" to many bbappends in order
to have most
libraries I use on my target also for nativesdk (I can compile my embedded
application also
for nativesdk then). As debugging performance using gdbserver is quite poor on
my system,
developing my application with nativesdk is a welcome alternative (that's why
I also have
enabled debug information nativesdk).
But from some previous comments on the OE list it seems that nativesdk is not
really intended
for this purpose. But what is the alternative? Having two SDKs?
regards
Christian
