Hi,
By default, Yocto uncompress files with an extension use for compression
(include it tgz), so any file that you add to the SRC_URI, Yocto will do the
uncompress in the do_unpack task. Because do_install depends on do_unpack, when
you want to use that task, you will already have the uncompress data available,
and you only need to copy into the right folder.
You can see the whole list of tasks that your recipe has with the command:
bitbake <name_recipe> -c do_listtasks
After that you can use the do_install task to send the files that you need to
the destination rootfs using the ${WORKDIR}, ${S} and ${D} variables of
bitbake. You can see the openemebedded-core layer for some inspiration. If you
want to see what exactly is in the WORKDIR directory, you will get the whole
path with the following command:
bitbake -e <name_recipe> | grep ^WORKDIR= | sed -n -e 's/^.*WORKDIR="//p' | sed
-n -e 's/".*$//p'
PS: Please take into consideration that you should never use absolute paths in
Yocto and use the predetermine variables for that (${WORKDIR}, ${S}, ${D}, etc)

Subject: [EXTERNAL] [yocto] reading tgz file and uncompress in rootfs
External Message:Use caution before opening links or attachments
Hi, I have requirement where recipe file reads set of .tgz files and it should
store in a location in rootfs and untar them(on freescale board). Can you
please show some pointers.
SUMMARY = " Tools"
LICENSE = "CLOSED"
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRCREV = "${AUTOREV}"
SRC_URI = "file://tool1.tgz
file://tool2.tgz<file://tool2.tgz/>
file://tool3.tgz<file://tool3.tgz/>
file://tool4.tgz<file://tool4.tgz/>"
do_install () {
install -d ${IMAGE_ROOTFS}/usr/share/sigma-tools
for file in ${WORKDIR}/.tgz;do
tar -xvzf $file -C ${IMAGE_ROOTFS}/usr/share/<folder>
done
Alternatively instead of for loop tried below
tar -xvzf file://tool1.tgz -C ${IMAGE_ROOTFS}/usr/share/<folder>
tar -xvzf file://tool2.tgz -C ${IMAGE_ROOTFS}/usr/share/<folder>
tar -xvzf file://tool3.tgz -C ${IMAGE_ROOTFS}/usr/share/<folder>
tar -xvzf file://tool4.tgz -C ${IMAGE_ROOTFS}/usr/share/<folder>
But when I build following is the error
DEBUG: Python function extend_recipe_sysroot finished
DEBUG: Executing shell function do_install
tar (child): Cannot connect to file: resolve failed
gzip: stdin: unexpected end of file
tar: Child returned status 128
tar: Error is not recoverable: exiting now
Can you please suggest to resolve errors and provide solutions
Thanks
