Hey guys, i've got r8187 compiled and insmoded ok

Tryed once again compiling r8187 and trying to understand every step i was doing

Thanks paulkoan for this tip

Ok, here are the steps i did so anyone can build it:

1. at scratchbox download the rtl8187 source
wget http://dl.aircrack-ng.org/drivers/rt...ux_26.1010.zip

2. Unzip and enter source folder
unzip rtl8187_linux_26.1010.zip
cd rtl8187_linux_26.1010.0622.2006/

3. Download patch
wget http://patches.aircrack-ng.org/rtl8187_2.6.27.patch

4. Unpack driver and stack
tar xzf drv.tar.gz
tar xzf stack.tar.gz

5. apply the new patch:
patch -Np1 -i rtl8187_2.6.27.patch

6. edit ./beta-8187/r8187.h
change the line:
#include <asm/semaphore.h>
to:
#include <linux/semaphore.h>

7.edit ./beta-8187/Makefile
change the line:
EXTRA_CFLAGS += -mhard-float -DCONFIG_FORCE_HARD_FLOAT=y
to:
EXTRA_CFLAGS += -msoft-float -DCONFIG_FORCE_HARD_FLOAT=n
(Thanx to qwerty12)

8. Compile stack against kernel-power-headers
make -C /usr/src/kernel-power-headers/ M=/targets/FREMANTLE_ARMEL/usr/src/rtl8187_linux_26.1010.0622.2006/ieee80211/ modules

9. Remove ./beta-r817/Module.symvers and link the one at the folder ieee80211:
rm -f ./beta-8187/Module.symvers
ln -s ../ieee80211/Module.symvers ./beta-8187Module.symvers
(Thanxs to paulkoal)

10. Compile driver against kernel-power-headers
make -C /usr/src/kernel-power-headers/ M=/targets/FREMANTLE_ARMEL/usr/src/rtl8187_linux_26.1010.0622.2006/beta-8187/ modules

Note: If its fails saying it needs ECHI KERNEL SUPPORT remove lines referencing this at ./beta-8187/r8187_core.c
(Thanx qwerty12)

11. Copy modules to your N900, rmmod modules for wifi and mac80211 stack and insmod new modules in sequence.
rmmod wl12xx
rmmod mac80211
insmod /path.to.your.modules/ieee8011_crypt-rtl.ko
insmod /path.to.your.modules/ieee8011_crypt_wep-rtl.ko
insmod /path.to.your.modules/ieee8011_crypt_tkip-rtl.ko
insmod /path.to.your.modules/ieee8011_crypt_ccmp-rtl.ko
insmod /path.to.your.modules/r8187.ko

You are done.

Its works without any external power source , at list for the moment

Now im going to experiment a little

Thanx to everyone who helped me and, of course, h-e-n developers. (rtl8187 stack mac80211 is next)
