Hi All,
I have hello_2.7.bb file which contains as below
vim hello_2.7.bb
DESCRIPTION = "GNU Helloworld application"
SECTION = "test"
LICENSE = "BSD"

LIC_FILES_CHKSUM =
"file://${COMMON_LICENSE_DIR}/BSD;md5=3775480a712fc46a69647678acb234cb"
SRC_DIR ?=
"/home/rajesh/poky-krogoth-15.0.2/meta/recipes-support/hello/hello_2.7"
SRC_URI = "file://${SRC_DIR}"

S = "${SRC_DIR}"

do_compile (){
        make prog
}

do_install(){
        install -d ${D}${bindir}
        install -m 0755 ${S}/hello  ${D}${bindir}
}

in hello_2.7 folder i have two files hello.c and Makefile
vim hello.c
#include<stdio.h>
int main()
{
        printf("hello YOCTO POKY\n");
        return 0;
}

Vim Makefile
prog:
        gcc -o hello hello.c

Now when i am building "bitbake hello", I am  getting below error in
poky-krogoth-15.0.2.
The same hello_2.7.bb  is compiling fine without any error in
"poky-dora-10.0.0".
The strange thing i observe in poky-krogoth-15.0.2. is that hello.c and
Makefile are getting erased in hello_2.7 dir.
Am i missing some thing in poky-krogoth-15.0.2? Please help.

You probably need to use externalsrc facility:

You don't want to set S to this as you're then building things in your
metadata directory. I suspect the code in more recent versions cleans
${S} before fetching/unpacking and this is wiping out your files.

You probably want S = "${WORKDIR}" or maybe S = "${WORKDIR}/hello_2.7",
I can't remember exactly where the fetcher places a directory of files.

Cheers,

Richard

Hi Richard,
setting S = "${WORKDIR}/hello_2.7" or S = "${WORKDIR}"  didn't work. I used

in build/conf/local.conf

INHERIT += "externalsrc"
EXTERNALSRC_pn-hello =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"
EXTERNALSRC_BUILD_pn-hello =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"

in hello_2.7.bb

EXTERNALSRC =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"
EXTERNALSRC_BUILD =
"/home/rajesh/Downloads/poky-krogoth-15.0.2/meta/recipes-extended/hello/hello_2.7"

now i could compile.

Thanks,
Praveen.

I don't see why you would need to modify the global local.conf. Just put 
'inherit externalsrc' to the recipe file.
