Re: [OpenWrt-Devel] Reducing the root file system in openwrt
Arjav,
As far as I know, the final package will end up in the "staging_dir"
directory, not the build_dir. Inside the build_dir will be all the binaries
compiled by the package.
Try doing something like:
1) Edit the Makefile(s) and remove the lines that install binaries you
don't want.
2) Issue: make V=s package/"the package you are compiling"/{clen,install}
3) Check the bin and staging_dir directories (the bin directory is where
the final package will be, in the staging_dir, you can check what was put
inside the package)

Re: [OpenWrt-Devel] Reducing the root file system in openwrt
Hi Ronaldo, I tried doing that by removing the copy line in Makefile but anyhow those files come into build_dir. I suspect that those files get included from dl directory. Is my understanding in this correct? If I remove packages from dl directory then I get compilation errors.

Re: [OpenWrt-Devel] Reducing the root file system in openwrt
Arjav, I'm not 100% sure of that, but if I were you I would take a look at the Makefiles that generate those packages whose files you don't want to be included in the final build image. Often the "install" directive of an OpenWrt Makefile is where developers "include" the files they want to be include in the final image. Here is an example of libbz2 package: 77 define Package/libbz2/install 78 $(INSTALL_DIR) $(1)/usr/lib/ 79 $(CP) $(PKG_BUILD_DIR)/libbz2.so.$(PKG_VERSION) $(1)/usr/lib/ 80 $(LN) libbz2.so.$(PKG_VERSION) $(1)/usr/lib/libbz2.so.1.0 81 endef For example, if you don't want the "libbz2.so" to be included, you can remove lines 79 and 80. 2018-03-07 9:00 GMT-03:00 Arjav Parikh : > Hi Ronaldo, > > I am building firmware for IPQ806x platform.

Good point, looking at https://downloads.openwrt.org/releases/17.01.4/targets/ipq806x/generic/ and https://downloads.openwrt.org/snapshots/targets/ipq806x/generic/, with the exception of the openwrt-ipq806x-vmlinux.elf image, all of the images on there are under 10MB and most are under 6MB.

Hi Arjav, Are you really using a real OpenWrt? The presence of the "wigig-firmware" package makes me suspect that you're using the "QSDK" fork instead. In that case, you should probably ask QCA for support instead. We won't be able to help you properly, since the system that you're using is very heavily modified in many ways. - Felix ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel

Is this a new package? Newer heard about wigig-firmware. Maybe this isn't actually OpenWrt from openwrt.org. But when it is, then you should not modify the generated root directory but just go into `make menuconfig` and deselect the wigig-firmware entry.

Re: [OpenWrt-Devel] Reducing the root file system in openwrt
Hi Ronaldo, I am building firmware for IPQ806x platform. I have been able to reduce my firmware image from 22 MB to 10 MB by disabling unwanted kernel modules and libraries using make menuconfig. But there are files in root-ipq806x/lib/fimrware directory of approx size 4.4 MB. I do not require any of the files present in this directory. I tried to remove those files by removing its entry from root-ipq806x/usr/lib/opkg/info/wigig-firmware.list assuming that on next build these files wont appear but still the files are there in /lib/firmware directory. By removing these files I can further reduce filesystem by 4 MB. On Wed, Mar 7, 2018 at 5:07 PM, Ronaldo Afonso wrote: > Hi Arjav, > > Which kind of firmware are you using?

Hi Arjav, Which kind of firmware are you using? An OpenWrt prebuilt (from https://downloads.openwrt.org/releases/) or a firmware build by yourself?
