Kernel module.. two steps forward.. ten back

For Developers

trying to build a few tcp congestion modules.. for stock openwrt rather than building all my own images.. (seeing if this is easier..)

snapshot uses apk.. so I build a module and tried to install..

apk add kmod-tcp-westwood-6.6.74-r1.apk --allow-untrusted
ERROR: unable to select packages:

went back to the src and from the snapshot motd..

 OpenWrt SNAPSHOT, r28694-730db6b893

git checkout 730db6b893

did a make clean; then make -j(nproc).. waited a while

put my test module into package dir

make menuconfig (pick the package both M and * now end up the same way..)
make package/westwood_mod/compile

and (of course it tells me) tcp_westwood_mod.ko is missing..

docs/guide-developer/toolchain/single.package#kernel_modules

make target/linux/compile and make package/kernel/linux/compile then make package/westwood_mod/compile gives the tcp_westwood_mod.ko is missing..

and it very much is missing..

I modeled my files after this post:

I've been doing this two or three days with the only problem being the build version different than the module version.. (or so I think.. )

I'm not sure what this is, but the goal is to install version, git clone the src for that version/commit and build a few modules for it.. and load/use them successfully..

(should it matter) I have a pair of mt3000's that I'm testing with..

Thank you in advance.

Hey there.. thanks for responding..

yes I modeled my module after yours.. and it was working.. not sure what I'm doing wrong, but the module is not building.. everything just reiterates that there is no module built..
