driver compilation, was the compilation successful?

[jimmywithtorch]

Hi everyone, I'm new to linux and I am trying to get my wireless card working. It is Dlink DWL 520 with realtek rtl8180 chipset. I got its source and I am now trying to compile and install it on Mankrake 9.2

Below is the output of 'make', please have a look at it and let me know if it got compiled correctly, because the driver is not working, so I can figureout if I didn't compile the driver correctly or there is some other problem.

Thank you all

It generally looks ok, there are a few compile warnings todo with the actual code, but i suspect that if others have been able to get this driver working then it should be ok.

You may want to submit the output of the make command, along with details of your system to the driver developer/maintainer, as idealy code should compile cleanly, especially code that will be running in the kernel.

when 'make' or 'make install' (which basically copies the compiled stuff to where it needs to live permenantly) have problems they end with either

error1

or

error2

messages.

Warning messages are just that, warnings. They are not errors.

So, by the looks of it, your make worked.

Did you read the README or INSTALL file that probably came with the package? Did it tell you to do a './configure' first or just a 'make' followed by 'make install' ?

have fun

This is what readme file says about installation

------------------------------------------------------------------------------------
< Installation >
Please try to load linux_24x.o first by "insmod -f rtl8180_24x.o".
If it doesn't work, you are suggested to compile loadable driver module following the steps as:

(0)Make sure the C-compile version. Run "gcc -v".
If gcc version is 2.xx, use release driver RTL8180_24x_RH73.zip.
If gcc version is 3.xx, use release driver RTL8180_24x_RH90.zip.

(1)Modify macros in Makefile.
KERNELRELEASE - represent kernel release version
IO_FLAGS - pci I/O space mapping
ENDIAN_FLAGS - big/little endian
OP_MODE_FLAGS - Operation on either AP or Client mode
DRV_FLAGS - Driver debugging messge ...etc.

(2)Check pci module initialization and system call interfaces in the provided source code,
r8180_pci_init.c ....etc.

(3)Run 'make' to generate new driver module.

(4)Run 'make install' to install new driver module.

(5)Refer to < Set wireless lan MIBs > and modify script files,
wlanup/wlandown, to set Wireless LAN specific parameters.
Run wlanup/wlandown to activate/shut_down wireless lan.
Usage:
./wlanup {ap|infra|adhoc}
./wlandown
Note:
- "./wlanup ap" works if OP_MODE_FLAGS is assigned RTL_ACT_AS_AP in Makefile.
- "./wlanup {infra|adhoc}" works if OP_MODE_FLAGS is assigned RTL_ACT_AS_AP
in Makefile.
------------------------------------------------------------------------------------

I checked pci module initialization and system call interfaces as specified in step (2) and the macros discussed in step (1) are inserted as environment variables in the make file

e.g.
#-----------------------------------------------
#Specify kernel version and include path
#-----------------------------------------------
KERNELRELEASE=$(shell uname -r)
INCLUDEPATH=-I /usr/src/linux-$(KERNELRELEASE)/include/
INSTALLPATH=/lib/modules/$(KERNELRELEASE)/kernel/drivers/net/wireless


So I think I can leave them as variables. Though I varified if I have everything at these paths i.e. /usr/src/linux-2.4.22-10mdk/include/ etc.

I also read many thread about this driver and some managed to get the wireless card working and some got partial sucess and some didn't at all. So I think the code is not compatible with all the kernel versions.

Because as you both said the compilation looks ok. so I did make install
then insmode. But I cannot see wlan0 in ifconfig. and whenever I do insmode to bring this driver up, my system won't shutdown properly. It hangs midway while shutting down and I have to press the switch to shut it down.

So I will try for a while if I get it working otherwise I will wait for them to update driver version.
