hi andrei,
you are right, my last answer was actually fror a different problem.
after looking into this issue, which is basically finding a way to make
-j n (with n > 1) work:
--- in short ---
so add a custom dependency:
######### interface/vmcs_host/CMakeLists.txt #########
if (BUILD_WAYLAND)
wayland_add_protocol_server(
VCHOSTIF_SOURCE
../../interface/wayland/dispmanx.xml
dispmanx
)
+ add_custom_target (myVmcs_hostTarget DEPENDS
wayland-dispmanx-server-protocol.h)
######### interface/khronos/CMakeLists.txt #########
add_library(wayland-egl ${SHARED} ${WAYLAND_EGL_SOURCE})
+ add_dependencies(wayland-egl myVmcs_hostTarget)
install(TARGETS wayland-egl DESTINATION lib)
note: i consider this a rather hacky solution. it works but assumes the
filename to be wayland-dispmanx-server-protocol.h even though if someone
changes the cmake function called 'wayland_add_protocol_server' (which
comes with the patch) to use a different filename, it will break.
the cmake background is described here:
#
http://stackoverflow.com/questions/4010212/cmake-struggling-with-add-custom-command-dependencies
tested with: conf/local.conf:
BB_NUMBER_THREADS = "4"
PARALLEL_MAKE = "-j 4"
--- in long ---
commands used:
bitbake -c clean userland
bitbake -f -c compile userland
target: userland

fatal error: interface/vmcs_host/wayland-dispmanx-server-protocol.h: No

also
/home/linux/yocto/poky/build/tmp/work/raspberrypi-poky-linux-gnueabi/userland/git-r5/build/interface/khronos/
explanation?:
in
/home/linux/yocto/poky/build/tmp/work/raspberrypi-poky-linux-gnueabi/userland/git-r5/git/interface/vmcs_host/vc_vchi_dispmanx.h
rewrite:
#include "interface/vmcs_host/wayland-dispmanx-server-protocol.h"
to:
#include "interface/khronos/wayland-dispmanx-server-protocol.h"
and it compiles!
this means either:
- include path is wrong and should be corrected in
interface/vmcs_host/vc_vchi_dispmanx.h or
- someone forgot to add vmcs_host/wayland-dispmanx-server-protocol.h
but
/home/linux/yocto/poky/build/tmp/work/raspberrypi-poky-linux-gnueabi/userland/git-r5/build
./interface/khronos/wayland-dispmanx-server-protocol.h
./interface/vmcs_host/wayland-dispmanx-server-protocol.h
so it seems more likely that
'/home/linux/yocto/poky/build/tmp/work/raspberrypi-poky-linux-gnueabi/userland/git-r5/build'
must be an include path to make it work! how to do that? turns out, it
is! so why is it not used then?
tested #include <> vs #include "" but then it worked with either??!!
possible new solution:
there is probably a copy operation but it was too late so the next run
it works which explains the odd behavour! so where is the copy command?
the line which borks the include path is from:
