7 years ago Hi, I've just pushed a large commit, finally moving from OpenWrt CC to LEDE (which will soon see its first release 17.01). This is the largest build system rework in the history of Gluon.
Most of the changes have already been worked into the documentation on ReadTheDocs, this mail will highlight a few important points to consider when updating to the new version:
Repository cleanup
The build directory layout has changed; if no new clone is made after the update to the latest Gluon master, the directories "build" and "openwrt" should be removed completely.
Build
The Gluon Makefile has been rewritten to remove a lot of old hacks. This,
together with bugfixes in LEDE, should make uses of the make clean
command unnecessary in most cases, and a usual build will just consist of
the commands:
git pull make update make GLUON_TARGET=...
This should significantly speed up incremental builds.
Site changes
Only minor changes to the site configuration are necessary.
-
site.conf
- The opkg.openwrt key has been replaced by opkg.lede. If your network has IPv6 internet connectivity, it may be dropped altogether as the new default server downloads.lede-project.org does support IPv6.
-
site.mk
-
Profile names have changed and now refer to individual images, so device-specific site package definitions need to be adjusted, for example:
GLUON_tp-link-tl-wr841n-nd-v11_SITE_PACKAGES := ...
-
Note that we no longer omit device-specific packages defined by LEDE's defaults, so devices with USB will now usually include the drivers for the USB controller.
Targets
Due to further size increase of the kernel between 3.18 and 4.4, we were not able to keep support for devices with 4MB flash in the ar71xx-generic target. For this reason, we've introduced the slimmed-down ar71xx-tiny target, which does not contain opkg, so no installation of new packages is possible without rebuilding the image. This is probably not a significant degradation, as the overlay was already too small for useful package installations on these devices before.
The x86-kvm_guest target has been dropped from LEDE; x86-64 should be used instead. 32-bit KVM images are not supported anymore.
Other changes
LEDE does not contain Telnet anymore; instead it is using password-less SSH by default. The config mode has been adjusted.
Development
Many make targets like "prepare" and "image/*" have been retired. Instead, commands like the following can be used to build individual images during development:
make GLUON_TARGET=ar71xx-tiny DEVICES='tp-link-tl-wr841n-nd-v11'
Multiple devices may be passed separated by spaces.
The build system has been improved not to break anymore when commands are executed in the "lede" (previously "openwrt") subdirectory. This is now officially supported, the following command can be used to prepare the LEDE tree for a specific Gluon target:
make GLUON_TARGET=... prepare-target
This will create the .config in the LEDE tree that would also be used for
normal Gluon builds. Afterwards, any LEDE make target (things like make package/.../prepare etc.) can be used directly in the lede subdirectory,
instead of providing a limited subset of commands available through the
Gluon Makefile.
Known issues
WLAN issues on the TL-WR1043ND v1 and similar devices with old AR91xx chips seem to have become even more severe lately. Due to another issue (that we're working on) the devices will quickly OOM after the WLAN adapter hangs (probably due to filling send buffers), leading to a reboot.
Please test the new version thoroughly and report issues you find on Github
