zoromba · March 3, 2022, 2:33pm

can you help me to make this package for openwrt

frollic · March 3, 2022, 2:38pm

haven't done it in a while, but have a look at Kernel module build but not installed to image

Grommish · March 3, 2022, 7:21pm

There is no reason to put two topics on the same thing..

@tmomas Can these be merged?

i able to build kmod-ipt-faketcp with this Makefile:

frollic · March 4, 2022, 2:50pm

probably want to enable verbosity during compilation ....

-j1 V=s, if i remember correctly.

zoromba · March 4, 2022, 2:59pm

this the output of make package/iptables-mod-faketcp/compile V=sc

zoromba · March 4, 2022, 3:50pm

problem solved when i changed the PKG_BUILD_DIR thanks all for your help

Grommish · March 4, 2022, 5:32pm

You had asked about local files vs the Git repo in the other thread.

If you have any interest in sending in a Pull-Request for that package, so that others might also use it if they find a need for it, you'll need to reference something outside of your local machine. Also, the build system will pull the repo, archive it and stash it in dl/ (the error you were seeing previously about invalid archive formats is due to this)

zoromba · March 4, 2022, 6:34pm

i will give the working makefiles, my friend helped me to make this work so the first Makefile is for kmod-ipt-faketcp:


Makefile of kmod-ipt-faketcp

you can edit it if you want
