How to extract an archive in a git repostry and copy it to a defined position in the rootfs?

How to extract an archive in a git repostry and copy it to a defined position in the rootfs?

Hej

I like to build an package out of a git repro. This git repro contains 
compressed files. One of these files I like to copy into my package. I 
looked into the documentation, but it is only described how to use the 
fetcher of bitbake. Think I need to add some extra lines of instruction 
after fetching.

Maybe you have an idea how to solve that.

My example:
#Source:
-> gitsm:/myGitServer.com/UnpackExample;protocol=http;branch=master
-> Dir struct:
- UnpackExample
        - win
        - linux
                - x86
                - arm
                        - example.tar.gz
#Dest:
example.tar.gz -> opt/*.*
del opt/xyz.bin

#Pseudo recipe:
SUMMARY = "my test"
SECTION = "test"
LICENSE = "CLOSED"

PVBASE := "${PV}"
PV = "${PVBASE}.${SRCPV}"

SRCREV = "${AUTOREV}"
SRC_URI = 
"gitsm:/myGitServer.com/UnpackExample;protocol=http;branch=master"

S = "${WORKDIR}/git/linux/arm"

??? do_fetch_append () {
???     extract ${S}/example.tar.gz
??? }


??? do_install () {
???     copy ${S}/ ${D}/opt/
??? }

FILES_${PN} += "/opt/*"

# skip QA that is checking for the GNU_HASH
INSANE_SKIP_${PN} += "ldflags"
########## end of recipe ####################

Regards!

It's a tarball so use "tar" to extract, and you'll need to mkdir ${D}/opt
before copying. but that's barely just pseudocode.

The only gotcha is that do_fetch() is a Python function so you can't just
append shell code.  Simply move the extract into do_install().

Thanks for the help! The solution is simple. As mentioned by Ross No 
do_fetch extension is needed. The extract + copy goes into do_install.

#### part of the recipe ####
do_install () {
        install -d ${D}/opt
        tar -xzf example.tar.gz -C ${D}/opt/
}

FILES_${PN} += "/opt/*"
