[bitbake-devel] need help to write a recipe to link a static library to my application

[Viditha Murahari]

I'm new to yocto and bitbake and I'm building a voip application for a
custom imx6 board. I want to use  pjsip libraries to build my application,
I have compiled pjsip in my yocto build and generated pjsip libraries ( all
pjsip libraries r static). I'm having issues building a recipe for my
application that calls the pjsip functions. Below is how my recipe looks


Filename: rttapp.bb

DESCRIPTION = "Simple voip application"
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM
="file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
PR = "r1"

SRC_URI += "file://rttapp.c"
SRC_URI += "file://include"
SRC_URI += "file://lib"

S = "${WORKDIR}"

CFLAGS_prepend += "-I${WORKDIR}/include -DPJ_AUTOCONF=1
-DPJ_IS_BIG_ENDIAN=0 -DPJ_IS_LITTLE_ENDIAN=1"
LDFLAGS_append += "-L${WORKDIR}/lib -lpjsua2-arm-poky-linux-gnueabi
-lstdc++ -lpjsua-arm-poky-linux-gnueabi -lm -lrt -lpthread -lasound"

do_compile() {
${CC} ${CFLAGS} ${LDFLAGS} rttapp.c -o rttapp
}




When i do bitbake rttapp, the error i see is as below


Log data follows:
DEBUG: Executing shell function do_compile
/tmp/cc6nn4Dp.o: In function `main':
/usr/src/debug/rttapp/1.0-r1/rttapp.c:159: undefined reference to
`pjsua_create'
collect2: error: ld returned 1 exit status
WARNING: exit code 1 from a shell command.


Please advise
