IL/OMX_ headers on Raspberry Pi

[Andrew Benham]

Using a fresh git clone of baresip, building on a Raspberry Pi running bullseye (not buster), I can't find the -dev package which provides the IL/OMX_ headers which omx.h is looking for.

I've installed libomxil-bellagio-dev, but that's probably the wrong package - it provides OMX_ headers but not IL/OMX_ headers

the bellagio dev is there so that omx.so can be used on other
platforms, I think it is not needed anymore we should probably
remove support for bellagio


do you have a complete build log ?

Not sure it warrants a complete build log.

Line 127 of mk/modules.mk reads:

USE_OMX_RPI  := $(shell $(call CC_TEST,bcm_host.h))

which essentially determines whether the target is a Raspberry Pi,  It doesn't check whether the OMX library/header files are available.

modules/omx/modules.mk does:

ifneq ($(USE_OMX_RPI),)
$(MOD)_CFLAGS»··:= -DRASPBERRY_PI -DOMX_SKIP64BIT \
         -isystem /usr/local/include/interface/vmcs_host/linux/ \
         -isystem /usr/local/include/interface/vcos/pthreads/ \
         -isystem /opt/vc/include \
        ·-isystem /opt/vc/include/interface/vmcs_host/linux \
        ·-isystem /opt/vc/include/interface/vcos/pthreads
$(MOD)_LFLAGS»··+= -lvcos -lbcm_host -lopenmaxil -L /opt/vc/lib
endif

ifneq ($(USE_OMX_BELLAGIO),)
$(MOD)_LFLAGS  += -lomxil-bellagio
endif

with no checking whether these files exist.

So when modules/omx/omx.h does

ifdef RASPBERRY_PI
#include <IL/OMX_Core.h>
#include <IL/OMX_Video.h>
#include <IL/OMX_Broadcom.h>
#else

it all blows up:

$ make LFLAGS=-Wl,-rpath=/usr/local/lib --trace

The supposition is that any Raspberry Pi will have the required files installed.  And there's no instructions on how to get them if they aren't installed.
