Hello!
Is it possible to change values of parameters in .config depending on chosen target/subtarget ?
Case1 : I want to use another toolchain which path I have in my .config after switching on another target/subtarget.
Case2: I want to use another set of enabled packages for different target/subtarget.
Hi @AncientApparition,
if you just want to change values after having selected the target/subtarget, you can use make menuconfig
(and if you want to use a file to keep track of changes for your specific build make defconfig
):
Using this way, you can configure the use of an external toolchain as follow:
https://openwrt.org/docs/guide-developer/external_toolchain#step_2build_firmware
Now, if you really want to have all these settings changed when you select the target/subtarget, let us know as it involves quite a bit more changes (and unless you have new hardware specs possibly doesn't make sense).
./scripts/env
is probably the closest to what you need... search the forum... there are some posts by jeff explaining it's usage in more detail
For example I can use variable PACKAGE in target/linux/<my_target>/<my_subtarget>/<my_profile>.mk
Any < package> which I pointed here appears in .config automatically like "CONFIG_DEFAULT_< package>=y" when i chose this profile in menuconfig, so i don't need enable all this packages manually.
Does such logic exist for enabling CONFIG_PACKAGE_ automatically for non-kernel?
yes, you can create a "seed" .config file with the minimal amount of configuration that you require. Typically, your (SUB)TARGET as well as any package you would have to manually configure using make menuconfig
, and the run make defconfig
. This will have the same result as the manual editing. See the first link in my previous post for more details.
