HI,
800MB sounds fairly much for just the base system - maybe there is some
potential for you to slim it down.
If your project requires all these packages, I' afraid there isn't an
easy magical switch to reduce the size.
What you could do is take the image manifest
(https://www.yoctoproject.org/docs/current/mega-manual/mega-manual.html#var-IMAGE_MANIFEST)
and browse manually though it, if there
is any obvious package that shouldn't be installed, which could be
removed - but to be honest 3.9GB for all that stuff required according
to your list sounds like a reasonable size for the rootfs.
If you already know what the real "big ones" are in your image you could
try to configure them to include only things really needed - if not you
could also take the
image manifest feed the information into "oe-pkgdata-util package-info
<pkgname>" to get the size of the package.
I guess from here on you can take it.
In the end 3.9GB for a fully fledged development environment doesn't
sounds too much - just remember a vanilla ubuntu for example takes at
least 15GB.

Hi Konrad,
Actually my current image size is 3.9GB because of heavy size packages
required by my project and without project required packages my image
size in Yocto is 800MB.
I want to reduce the image size as maximum as possible.
Thanks a lot in advance,
Ajam Ali

Pretty general questions, but I try to answer your question.
I don't know what the purpose of your image is, but installing
development tools like boost-dev or gcc (I guess that is what you mean
with cpp) makes your image automatically a lot bigger, I would suggest
to put devtools into a SDK, which could be shipped separately.
Next thing you can do is to analyze the what is actually so big in
your image, e.g. by creating a tar.gz of the image, unpacking it and
browsing by 'du -sh *'.
You can get the package/recipe to a file by using 'oe-pkgdata-util
find-path <path>'.
In the identified recipe you can look for PACKAGECONFIG or
OE_EXTRACONF switches that you don't need and disable them.
As said, I don't know what the purpose/environment of your image will
be like, but you could also consider to use a different fs-format like
squash.
In general if you want small images preferring musl over glibc and
systemV over systemd is something that you could consider as well.
TL;DR
1) move to SDK
2) check PACKAGECONFIG switches
3) same as 2 or consider something "smaller" like lxc
4) same as 2
5) same as 2
6) same as 2
7) move to SDK
8) same as 2
