I installed Hardy on my ThinkPad R61 which using Kernel 2.6.24.

to know what’s the intel wireless card you have run the following command

lspci -vvnn

For my laptop:

03:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:4227] (rev 02)

running
iwlist scanning
gives me
lo        Interface doesn't support scanning.
eth0      Interface doesn't support scanning.
wmaster0  Interface doesn't support scanning.

digging for the source of the error i got this message in the log

dmesg | grep iwl

[ 68.062145] iwl3945: Microcode SW error detected. Restarting 0x82000008.
[ 68.062169] iwl3945: Error Reply type 0x00000005 cmd REPLY_SCAN_CMD (0x80) seq 0x4414 ser 0x0000004B
[ 69.064840] iwl3945: Can't stop Rx DMA.
[ 69.196238] Registered led device: iwl-phy0:RX
[ 69.196280] Registered led device: iwl-phy0:TX

I tried this trick, to solve the problem

1. sudo modprobe -r iwl3945
2. create a file named iwl3945 in /etc/modprobe.d
3. in that file enter the following entries
alias wlan0 iwl3945
options iwl3945 disable_hw_scan=1
4. sudo modprobe iwl3945
5. sudo ifconfig wlan0 up

after that i got my wireless card working, but not the wireless LED. For me that is enough

If you don’t want to compile, you can install it easily from Ubuntu repositories,
sudo apt-get install pdfedit

If you insist on compiling, you can get the source files , Here.
Now you need to extract your compressed file, in my case :
tar -xzvf pdfedit-0.4.1.tar.gz
You also need the following packages, qt3-dev-tools, build-essential, boost-build, libboost-thread-dev , libboost-thread1.34.1 , libboost-iostreams1.34.1 and libboost-iostreams-dev , on Ubuntu you can run :
sudo apt-get install build-essential boost-build libboost-thread-dev libboost-thread1.34.1 libboost-iostreams1.34.1 libboost-iostreams-dev qt3-dev-tools
Now you need to set the QTDIR, which is the qt3 directory, if you are using Ubuntu you it is usually on /usr/share/qt3, so :
export QTDIR=/usr/share/qt3
Now all what you need to do is to go into your extraction folder and run the configuring script :
./configure
If you followed all of the above steps this should run smoothly. To install run :
make install

ENJOY!
