Build not working if cross compile about rtl8192eu-linux-driver

[masterzorag]

@Alex66955 cross-compile is supported, as build out-of-tree is supported;
Your Warning is just a warning, but you are building against kernel-headers instead of full kernel-sources;
Example:

blackbox RTL8192EU-linux # pwd
/Storage/RTL8192EU-linux

blackbox RTL8192EU-linux # make KSRC=/Archive/linux-4.12.10
make ARCH=x86_64 CROSS_COMPILE= -C /Archive/linux-4.12.10 M=/Storage/RTL8192EU-linux  modules
make[1]: Entering directory '/Archive/linux-4.12.10'

  WARNING: Symbol version dump ./Module.symvers
           is missing; modules will have no dependencies and modversions.
...

blackbox RTL8192EU-linux # ls -l 8192eu.ko 
-rw-r--r-- 1 root root 2358944 Sep  6 10:15 8192eu.ko

So, try just appending KSRC=/path/to/kernel-source to your make invocation, like this:

make ARCH=arm CROSS_COMPILE=arm-v7a-linux-gnueabihf- KSRC=/path/to/kernel-source

Note that:

• at least make modules_prepare has to be called (on kernel-source) before building Realtek module!
• you have to change target into Makefile module source

Also, consider moving to linux-4.4 if you get any more issues.

Thank you very much.
It is working now and I could test the driver in Client and AP-Mode!

Hi.

Which branch are you using ? master or realtek-4.4?

Cross compile must work, this driver is used by projects like OpenElec and LibreElec for all architectures, including IMX6.

Based on the code from LibreELEC master branch compiles with 3.14, 4,4, 4.8 and 4.10.

I have tested the realtek-4.4 with the LibreELEC toolchain and kernel 4.4 and look good for me.

Thanks for the explanation above, just wanted to know how to locate the kernel folder in the beaglebone black. As I am trying to build the drivers for the same beaglebone black, do I need to mention the kernel files ?
