I need some help compiling a usb wireless adapter driver with a RTL8188CUS chipset (uses RTL8192CU driver) . This is my setup:
- Puppy 4.12 frugal install
- 512kb save file
- /mnt/home/devx_412.sfs, confirmed loading from terminal by typing cc command
- /root/rtl8192CU, the directory containing the driver source supplied with the adapter

I opened a terminal in /root/rtl8192CU and typed make, this is the output:

make ARCH=i386 CROSS_COMPILE= -C /lib/modules/2.6.25.16/build M=/root/rtl8192CU modules
make[1]: Entering directory `/lib/modules/2.6.25.16/build'
make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/lib/modules/2.6.25.16/build'
make: *** [modules] Error 2

Any ideas on how to get this to compile?

Thanks
Gary

You seem to lack kernel sources. Install kernel sources and try again.

I apologize to all who responded for my delay in getting back. In the past when I posted a question in the forum I would get an email when someone responded. If that system is still in place it didn't work so I thought no one had replied. Just for reference this USB adapter is 802.11B/G/N and VERY small, less than 1/2" square, just about the same size as the USB connector it is attached to, also very inexpensive, I bought mine on Ebay for $6.50 US including shipping. It works well on Windows, but of course I want to get it to work on Puppy. I work on mostly older P3, P4 hardware so that is why I use Puppy 4.12.

So here is the status:
@RetroTechGuy - thanks for the link, I downloaded and installed one of the pets in hopes it might work, but of course it didn't since it was compiled for the newer kernel. I will post a question in that thread.

thanks
Gary

@pemasu You are of course correct, I did not have the kernal installed, thanks

@Karl Godt I put the sfs file in /mnt/home/kernel-src-2.6.25.16-patched-puppy4.1.sfs and configured the boot manager to load it. When I run make in the terminal I get the same error message. I looked inside the makefile, but don't know enough to understand where or why it is throwing the error.

you can 'watch' or 'stop watching' topic using an option under the last reply.

(can't be of any help with driver unfortunately, apart to say someone has probably already compiled it somewhere)

[WiZard]

Muggins, I installed the .pet you posted and rebooted. Started the network wizard and the wireless device is not shown so I tried to manually load the driver. No driver listed for the 8188/8192 device and doesn't really look like any new RTL drivers were added. I can use rox and see the driver file /lib/modules/2.6.25.16/kernel/drivers/net/wireless/8192cu.ko but I can't load it. Your help is appreciated.

thanks
Gary

[pemasu]

In console: depmod -a
Then in console: modprobe 8192cu
Are you sure you dont need firmware for that driver also ?

[WiZard]

pemasu, thanks for the instructions. The device is now showing in the network wizard and I am using it to make this post. Problem now is I get a message box telling me the selected interface 8192cu does not support WPA which will be needed on many networks.

thanks
Gary

@muggins, I'm running Puppy 4.12 full install setup to compile per the instructions at http://puppylinux.com/development/compileapps.htm
I downloaded the driver from the Realtek site, Linux driver for Kernel 2.6.38(and earlier)


Questions about your message below:
1. "after getting the kernel source to load" how do I do this?
2. "change directory to /usr/src/linux-2.6.25.16" I don't have this diirectory?

thanks
Gary

[muggins]

Because you have a full install the kernel .sfs isn't loading. So you can either mount the kernel source, then copy everything across to your full install or, perhaps simpler, if you booted a CD/DVD, installed Shinobar's Sfs-Load .pet, then load both the devx & kernel source SFS files, then try compiling your module.

Also remember that Pemasu corrected me that it should be:

[WiZard]

muggins, tried the cd boot, installed sfs_load, loaded devx & kernel source. Ran make clean and make prepare successfully, but when I run make in the driver directory I get the same error message as always.
Did you compile on a 4.12 install?

thanks
Gary

[muggins]

Yes, I compiled it in p412. I'll have to try booting p412 into RAM, then see if I can retrace my steps to recompile it. I'll post back later.

[muggins]

OK. I booted p412, with prefix pfix=ram, installed Shinobar's sfs_load, then used it to load both the p412 devx & kernel sources.

I didn't do anything with the kernel source files, instead I just did, in the driver's extracted directory:
