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

Maybe it will not help you, but I would suggest you to use a complete development package.
I mean, you should use autotools or cmake to build your application locally, then package your source and inherit autotools or cmake. It will be easier for you to make things happend.
Hope this helps.

Try splitting this into two commands. First compile rttapp.c to
rttapp.o and then link the final application as a second step. When
linking the application, ensure that rttapp.o is listed on the command
line before the libraries which provide the symbols it requires.

I did a bitbake -e -c compile -f rttapp , and this is how my do_c0mpile
