You are not using a stock EL7 kernel for the build.

Please post the output for "uname -r".

You can only build kmod-wl from the srpm using a standard EL7 kernel (e.g., 3.10.0-693.21.1.el7.x86_64) and the resulting kmod-wl will only function with stock kernels in the same series.

[Sistemas-Dif@localhost ~]$ uname -r

just to let you know, you should be able to use the built in reverse engineered broadcom kernel module (driver) with

Code: Select all

modprobe brcmsmac
I'm using it now with 4.15 elrepo kernel, the problem (for me) is a download speed of around 2 Mbit/s which is fine for general web browsing but not so good for streaming etc. I get around 36 Mbit/s with the wl module.
Fedora use the latest kernel and the fusion repo provide a wl-kmod module that works with it, I'm guessing hacking the (fusion) srpm spec file and applying the latest broadcom patches would work, I just don't know how to apply a patch to an srpm and get it to work.
I tried once but got the same problem with locking up.
Maybe an email to the fusion repo for some guidance if you must use the latest kernel, or install fedora.
The CentOS kernel may be an older version number but it's as bang up to date as 4.15 patch wise.
