[bitbake-devel] Copying the files to sysroot

[Awais Belal]

Hi Ugesh,

 >> Where is the ${includedir} points too? by default it is /usr/ by GNU 
itself. is it somewhere redefined?

The includedir points to /usr/include under the ${D} which is 
${WORKDIR}/image. To be precise the includedir is directly set to 
${exec_prefix}/include where exec_prefix is usually set to /usr

 >> if [ ! -e $(includedir)/componentincludes ]; then

this if looks incorrect to me. It should probably be

if [ ! -e ${D}${includedir}/componentincludes ]; then

Please also move your inherit lines just below SRC_URI as keeping 
inheritance on top of everything is a good practice and would avoid some 
issues. Once you make these changes please rerun bitbake for this .bb 
file and then look at ${WORKDIR}/temp/log.do_install. The sysroot will 
not be populated with these headers unless one of the recipes DEPENDS on 
this first recipe. Also, in current implementation every recipe has its 
own sysroot components under ${WORKDIR}/recipe-sysroot/. So you need to 
look in <2nd-recipe-workdir>/recipe-sysroot/

BR,
Awais
