.config file not found for selected architecture in make menuconfig

For Developers

Hi,

When i compiling my package the .config file is not found. Before compiling i did select the architecture in make menuconfig and after that i did a make toolchain/install. i checked the folder where the .config should be located but it’s not there.

Whats the problem here?

What are you actually trying to do? Compile a new kernel package that needs the basic kernel?

The actual kernel would be built with make target/linux/compile

3

i execute this command: make package/newpackage/compile.

I want to build a new package out of my .c an .o files which i compiled before this, so that i have an .ipk file to install on target system openwrt.

The target system is a BCM2711 64bit.

When i compile the c program itself compiles but it stops here:

make[2]: Entering directory '/home/marc/openwrt/package/kernel/linux'

It cannot find the .config file

Are you using an SDK or buildroot? And which version? How was it set-up? Are all the host dependencies present? Where (as in which directory) and which commands are you executing?

5

Did you follow @hnyman 's advice to compile linux?
