Hi all. Had tried this post in the Slacky forum but they couldn't help mw out (hope I don;t get into trouble for double posting or something). Thought I would try here as I think it is probably a more appropriate forum.

Ok I am trying to compile conky 1.4.7 with wireless support, './configure --enable-wlan'

But the compile fails with.....

checking iwlib.h presence... yes
checking for iwlib.h... yes
checking for iw_sockets_open in -liw... no
configure: error: iw_sockets_open not found

This is a 'snip' from config.log

I have these files...
/usr/include/linux/wireless.h
/usr/include/wireless.h
/usr/include/iwlib.h
/usr/lib/libiw.a

I am running Slacky 11, Linux 2.6.21.6 (i686) with gcc 3.4.6.

I need Conky 1.4.7 as the previous version 1.4.5 does not have wireless support, as I understand it.

As usual any help or ideas would be very much appreciated.

BashTin.

Looks to me like you need to re-compile libiw with the --enable-shared option. Notice that it is trying to link to iwlib.so which doesn't seem to be on your system.

Thanks gnashly. You are helping me again :-)

Ok got the slakcy wireless-tools sources, wireless_tools.28.tar.gz, which is the package that contains libiw. Installed it (iwlib.so is built by default).

Conky now configures but make fails with.......

linux.o(.text+0xcbb): In function `update_net_stats':
: undefined reference to `iw_sawap_ntop'
collect2: ld returned 1 exit status
make[2]: *** [conky] Error 1

Do I need to install the wireless-tools sources?? If so where and how?

Thanks again, BashTin.

PS I know I will get into trouble for this but I have a thread about this on Slacky forum which, to be fair, I thought had died. Anyway I will close that thread and keep this one active as it has the more upto date info on my efforts.

Sorted now. Thanks again gnashly.

Just installed wireless-tools.29 as suggested by H_TeXMeX_H and conky made fine.

Thanks for your help, once again, BashTin.
