I noticed someone had a problem with radmrouted_BIN back in Feb., and I have a similar one but a bit different.

My problem is in starting the wview script. I get -

START --
xdc default # /etc/init.d/wview start
Starting wview daemons:
/etc/init.d/wview: line 50: 31208 Segmentation fault $RADROUTER_BIN 1 $RUN_DIRECTORY

STOP --
xdc default # /etc/init.d/wview stop
Shutting down wview daemons...

I am running Gentoo with AMD 64, and using the Debian init.d script. Someone here had said the Deb. init worked for them using Gentoo, but that COULD be the problem? I have successfully installed all programs to the best of me knowledge and all in the default settings. I am communicating okay with the VP Console. I have searched again and again to solve my problem, and reinstalled several times just to make sure. Same problem over and over with perfect installs each time.

I feel if I get past this hurdle all should fly, well hopefully anyway. Any help would be much appreciated..

I have a feeling this is to do with running on a 64-bt system - I tried doing a test/sim install on a sparc64/FreeBSD system a few months ago and it didn't run properly.

When running make on radlib and wview do you get warnings about pointers and integers?

Yes that's it! I get 1 warning when making wview and several making radlib. Both built ok with no errors, I should have scrolled through them better for those warnings.

There is just 1 "wview" warning, here in this section -
fi
../../stations/common/daemon.c: In function `evtHandler':
../../stations/common/daemon.c:466: warning: cast from pointer to integer of different size

There are several "radlib" warnings concerning the exact same issue. To many to be worth posting here.

I considered doing a Gentoo emulation build, but it would still come down to the 64 bit processor I wouild think. Back to the drawing board! I think I will just move my station over to an intel 3.0, 32 bit processor.

Perhaps some time down the road the developer will need to make it all work on a 64 bit platform as technology advances. Or perhaps it is already in the cards?

Thanks so much for the kind reply & your time!

I am getting the same behaviour on a fedora core 5 64 bit system. Interestingly enough, it starts just fine by hand...

Yes, I too could start it all by hand, but it didn't work, nor can it work in the present state of the program code unless you do some serious editting.. Meanwhile wine may be of some interest to you. I have vws installed under crossover.

I just worked on moving my installation over to an AMD 64 Debian (etch) box and ran into the same issue. All of the same results.

What was the wine/vws solution you used? I'd really like to get this working on my main server - for now it's the only thing running on another Intel box and I have the img directory NFS mounted for web publishing. It works, but I'd like to turn that box off.

Could someone with a 64-bit system try compiling with the -m32 flag set and report back?

clowntoe · Joined: 20 Jul 2006 Posts: 6

I'd love to help and I'm able to do this anytime soon. I just don't exactly know how to send the -m32 flag to the compiler. I've done a little research online but I think it's best to post in here for the others that run into this issue.

If anyone can help out, I'm happy to get started right away and post my results.

Bearing in mind that you'll need to do this for both radlib and wview, the instructions should be as per the user manual, but change
./configure
to
./configure CFLAGS=-m32

I'm working on this, but I'm getting an error from the compiler when passing that flag to it:

/usr/bin/ld: cannot find lgcc_s

libgcc is there, in /usr/lib. The path variable seems to be set correctly. Anyway, I'm researching to see if I can figure out the issue. When I don't pass the -m32 flag, configure runs properly.

I too was bitten by the 64-bit problems. I went ahead and fixed them (at least, it's working for me...). The hard part was finding out that the buffer sizes that radlib defaults to were no longer big enough for the bigger messages wview was generating! I've attached patches that make radlib-2.3.2 and wview-3.2.1 work on my AMD64 Debian Etch machine. I also made a lame attempt at Debian package creation - you can ignore the "debian" directories I created if you aren't using it; if you are, "fakeroot debian/rules clean; fakeroot debian/rules build; fakeroot debian/rules binary" should build the binary packages when you are in the correct project directories. Most of the patch size is due to the package creation stuff - the changes needed to make radlib and wview work on 64-bit weren't very big.

I don't think I did anything to break 32-bit support, but I haven't tried it out.

Since I don't see a way to upload the patches to this forum, I've placed them at:

http://www.evonetics.com/files/radlib-2.6.2-x86_64-patch

Thanks a million for the patches. They worked flawlessly for me as well.

Great job [quote="lockjaw"] ! I will be trying it soon out on my Gentoo build.
