Hi Rishi,

have a look at the bitbake file in the link:

http://www.multitech.net/developer/products/multiconnect-ocg/development/development-examples/

The error says you have a problem with your C program. Try posting the C program that you are trying to compile.

Best Regards,

JM

Hi JM,

Thanks for reply. problem is not with C program it is quite simple printf(“hellobrother”). May you help me write .bb file which can compile .c file from existing directory.

i suspect on following area in .bb file. it is still not behaving as i understood from opendembedded manual.

PR = “r1”

SRC_URI=”file://hellobrother.c”

S = “${WORKDIR}/${P}”

do_fetch () {

mkdir -p ${WORKDIR}/${P}

cp hellobrother.c ${WORKDIR}/${P}

}

Regards

Rishi

Hey Rishi,

take out this part:

do_fetch () {

mkdir -p ${WORKDIR}/${P}

cp hellobrother.c ${WORKDIR}/${P}

}

Also chnage S = “${WORKDIR}/${P}” to S = “${WORKDIR}

Update PR = “r2” so that the program compiles afresh. Give that a try.

Regards,

JM

do_compile () {

${CC} ${CFLAGS}${LDFLAGS} hellobrother.c -o hellobrother

}

You’re missing a space between CFLAGS and LDFLAGS on your compile line. It’s mashing the options together that get passed to gcc.
