I want to build a rtlwifi kernel module & thought the right thing to do would be to make a package. So I tried to follow the kernel package FAQ. It showed up in the make menuconfig, but the module wasn't being built.

After a while I noticed that these kernel modules are being overridden by the mac80211 package . I my  package stanza to the mac80211 Makefile. This tried to build, but gave errors that the .ko file wasn't found.

That's when I worked out that the kernel files aren't being used at all for that driver, and it's actually built in compat wireless. When compat-wireless builds, it looks like the makefile is being overridden by some build options pulled from ? When I try to build compat-wireless using the toolchain, it won't let me build that driver.

1) What is the right way to build this driver?
2) How can I get rid of compat-wireless and just use the kernel? What will that break?
3) has anyone else successfully got rtl8192cus working?

Still no clue how to make the package building work for mac81211 modules in the correct openwrt way.  Is it a problem with the install stanza?

What follows is a kludge, but there are  are a lot of rtl8192cu related posts that end  with a request & nobody responding. Here's at least something that worked once.

There's a patch below that will force compat-wireless to build the module. It won't build a package though, so you have to manually copy the rtlwifi.ko rtl8192c-common.ko and rtl8192cu.ko to /lib/modules on the openwrt. You'll also need to copy the rtl8192c*fw.bin firmware files from the  compat-wireless/ linux-firmware-something directory  into /lib/firmware/rtlwifi/

Patch is to package/mac80211/Makefile

Here's a working patch to package/mac80211/Makefile that enables rtl8192cu and results in the package actually being deployed to the build image/etc, without having to copy it manually or anything.

The trick was removing the "KCONFIG" directive (don't ask me why)

1. Get the latest development branch from svn
2. Apply the patch above to package/mac80211/Makefile (`cd trunk; patch < Makefile.patch`)
3. `make menuconfig`. Configure as appropriate. Select the rtl8192cu driver from Kernel section.
4. `make`
5. Flash firmware in bin folder.

Hello MichaelTyson, I have been trying exactly thatm thanks for the nice patch.

The only issue is that for a VERY  mysterious reason, it does not work. More precisely, when I add the following lines:

+    FILES:=$(PKG_BUILD_DIR)/drivers/net/wireless/rtlwifi/rtlwifi.ko \
+        $(PKG_BUILD_DIR)/drivers/net/wireless/rtlwifi/rtl8192c/rtl8192c-common.ko \
+        $(PKG_BUILD_DIR)/drivers/net/wireless/rtlwifi/rtl8192cu/rtl8192cu.ko

(or when I add a single file, say, rtlwifi.ko alone for instance), the command "make package/mac80211/compile V=99" fails with the following error: (and of course so does "make" wink )

Makefile:1614: *** missing separator.  Stop.

The line 1614 is the one where we have your patched line :

$(eval $(call KernelPackage,rtl8192cu))

The issue comes from inside the KernelPackage/rtl8192cu function. I tried a lot of things, paid a close attention to my tabs/spaces, used the code from other working drivers, well, as soon as I put a "FILES:=" directive in the rtl8192cu section, it's over.

Did I miss something really stupid ? I'm supposed to know quite a little about Makefiles, but there, I really don't get what's the matter. If you think you have a hint that could help me, of if you can reproduce the issue...

Thanks a lot for the patch anyway !

Hi vperron,

I can confirm the results.
Patch was merged successfully (though there was a few rejections that I had to add manually, probably something I did wrong to begin with).

To be honest, I have very limited knowledge with linux and actually compiled my first build of openwrt today.
I've read through the build package wiki and compared the makefiles to others in the system for syntax problems. Couldnt find any(I code on windows, so its not completely alien).

I'm also getting the same errors on the $(eval $(call KernelPackage call when trying to compile the make file posted here(lat line of makefile): https://forum.openwrt.org/viewtopic.php?id=39677
My ended state is to get an ALFA AWUS036NHR working on a Tplink WR703N (ar71xx).
MichaelTyson, your post gives me hope that I might actually get this going, thanks for posting your makefile.

Any suggestions on why we are getting this error? I'm sure its something stupid on my end, but a hint in the right direction would be wonderful. I noticed on the other thread that the line " TITLE=Realtek 8192C USB WiFi" is missing the : in front of the =, not sure how important it is. I'm not posting on the other thread as I suspect the problem is probably on my end, just dont know where.

If it makes a difference, I am using the guide posted on thepowerbase.com and the svn://svn.openwrt.org/openwrt/trunk/ repository. Build system is ubuntu 12.04 32bit running through vmware and was able to compile a valid image that I tested so I think the build system is good.

Well I was able to get past the error on the other make file I mentioned before that was getting the exact same error.
Basically the make file structure/syntax is extremely picky and errored out because of spaces instead of tabs.
I removed all the indents that were made up of spaces and replaced them with tabs and it compiled. I'm having other problems but its not related to this.
If I get a chance I'll try this patch again and let you know my results.

Also in the article that suggested the syntax, they mentioned that some text editors automatically change tabs to spaced indents on save, so verify later that they are still tabs.

Well I finally had a chance to test it out and it works.
Like I mentioned in my previous posts its a formatting issue.
The MakeFiles are extremely picky.

Using MichaelTyson posted script I did the following:

save the patch and ran it against package/mac80211/Makefile (cd trunk; patch < Makefile.patch) like he stated.
Then I went through the new Makefile and I changed the indentation on each line that was modified to what appeared correct looking at the rest of the files format (I'm still learning so I am not 100% sure if 2 spaces or a tab is more appropriate, but both seemed to work). I did it based on the code listed directly beside, some had spaces others had tabs.
On some lines there was about 5 spaces, which is problably what was stopping it.

The only other problem I had and it could have been with my setup and not the script is that rtl8192c*fw.bin does get compiled but its saved in /lib/firmware/ , rtlwifi is looking for it in /lib/firmware/rtlwifi/ so I just created the rtlwifi directory and cp it over.

Works like a charm and was able to get my adapter recognized and loaded. All features seeemed to work through LuCI even scanning which was mentioned not to work. Till I changed my device's IP address and for some weird fluke scanning stopped and it became very erradic like stated in the other topic started by MichaelTyson that I linked to.

Dear friends, I'm really happy that someone find a solutiun for module 8192cu but I don't want flash again the firmware.
I have alredy try on insert only the module compiled but I get several errors rtl8192cu: Unknown symbol.
Is possibile use the openwrtSDK attitude 12.09 and build only the package for module rtl8192cu? Thanks

@axishero: I get errors with your patch. I'm using OpenWrt Attitude Adjustment (r33369) from http://code.google.com/p/raspberrypi-openwrt/ and I don't know what I'm doing wrong.
Is there any other source for the rt8191 package meanwhile?

The discussion might have continued from here.
