help installing source code in slackware

plan9 · 08-23-2004, 11:18 AM

Hello,

I need to patch Openssh with a sftp logging utility. The only way that I have been able to apply the patch is to the raw source code of Openssh. I can configure and make it after that, but am having problems getting it to install in the correct place (it defaualts to /usr/local/bin).

From the research that i've done to date, I think that I need to modify the configuration script, during the build, and before i make a tgz out of it with checkinstall.

Does anyone know of a how-to on the subject of configuring a program from source code to build and install in the default slackware locations?

My guess is that I need to research the current location of Openssh, modify the ./configuration script from the raw Openssh source code to install in the same locations, and then build and install the program.

thank you,

plan9

If it's supposed to go in /usr/bin instead of /usr/local/bin you can:

Code:

./configure --prefix=/usr

You can do some research and find out where everything is supposed to be after that. If you have some discrepancies, just 'removepkg' on it, and then extract the package into a new folder on your desktop via:

Code:

tar -xzf mynewpackage.tgz

Then you can manually cut and paste stuff so it's organized the way it should be. Double check your install script to make sure it has all the right locations in it for creating symlinks and then do a "makepkg".....

It's a hack, but not really. It's fairly easy to make a proper slack-pak once you know where everything goes...

Thanks, it looks like I am on the right path. What should I do if there are multiple files being installed and the prefix that I use is different for them? For instance, in Slack sshd is located, by default, at /usr/sbin/sshd and the config files are located in /etc/ssh. If I do a ./configure --prefix=/usr/sbin all of the files are installed into /usr/sbin and the config files are installed in /etc, not /etc/ssh.

How does ssh "know" where the config files are? If it was installed thinking that they were in /etc/* but I then move them to /etc/ssh/* then it breaks the whole thing- right?

Are there settings for these config files (or any other files for that matter) with in the configure script somewhere?

thanks alot,

Here... Try this. If you do a "configure --help" I'm almost positive it will spit this stuff out at you...

Code:

./configure --prefix=/usr --sysconfdir=/etc/ssh --libexecdir=/usr/sbin

You ussually don't want to start moving stuff around like I mentioned earlier. Not when it comes to scripts anyway. You already picked up on that. Your right, the binaries won't know where to look then. You should rarely have to hand edit make scripts. Almost all programs come with a wide variety of compile options... Good luck tho...

jong357:

I found out about ./configure --help on my own a little earlier today. It gave me a bunch of override options for install locations. I then figured I first needed to know where everything was being installed with the slackware package so I could attempt to mimic it with the patched tgz that I am building. To do this I did a explodepkg on openssh, then a "ls- alR | less" to see where everything was going. I started building the new package in the /tmp dir while playing around with the configure options to try to get it right. I would build and install with checkinstall to the /tmp dir and then compare it using a "ls -laR" with the exploded tgz. I think that I am really close to getting it right now. If you would please take a look, at the outputs- I have a couple of questions at the bottom of the post.

here's the exploded list of the openssh tgz that shipped with slack (i have it exploded under installed):

===============================

As you can see, it's really close to the shipped tgz right now! About the only thing that is missing is the "install" directory, and I don't think that I need that. I am concerned about the missing files in /etc/ssh- but was planning on copying them over like you recommended early. what do you think? I am also concerned about /etc/rc.d/rc.ssh. I haven't had a chance to read it yet, but I am hoping that it will be able to start and stop the new binaries so long as they are named the same thing (they are) and are in the same locations.

Thank you so much for your help. Once I get this going I'll submit it to the author of the patch so that he can put it up for all slackware users.

Crazy idea, here: Why not go to the 'source' directory of one of the Slack mirrors and see how Pat built it?

From slackware-10.0/source/n/openssh/openssh.SlackBuild of one of the mirrors:

Quote:

./configure \
--prefix=/usr \
--sysconfdir=/etc/ssh \
--without-pam \
--with-md5-passwords \
--with-tcp-wrappers \
--with-default-path=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin \
--with-ipv4-default \
--with-privsep-path=/var/empty \
--with-privsep-user=sshd \
$ARCH-slackware-linux

Check it out and I'm sure you'll find a lot of useful info. After all, as all my old math professors used to say, 'why re-invent the wheel?'

Enjoy!

What a fantastic idea! Obviously, I had no idea that this info was available. From the source that you cited, it appears as though that is how he builds the tgz packages for slack. Would it be possible to take the source code for openssh, apply the patch and then build the same tgz there by saving others the hassle? how would you do this? it looks to me like all you would have to do is d/l everything in the openssh dir and then run openssh.SlackBuild- which would be nice because then it would install just like the original package! Please let me know what you think, and thanks!

plan9 · 08-24-2004, 03:27 PM

Hey what does the last line of the config script do? Here it is:
$ARCH-slackware-linux

I would guess that it sets the architecture of the package build, but it is causing my build to error out. it's set to
ARCH=ARCH:-i486 in the openssh-SlackBuild files?

jong357 · 08-24-2004, 06:14 PM

Yea, I'm sure he has an alias for slackware-linux that means i486.... Been awhile since I've used flags. march or whatever it is is what you want to set for an i486... I never thought of looking on the slackware site either.

Those are typical commands that I use for LFS, thats why I mentioned it. Sounds like you'll want your startup script in rc.d obviously..... I'd copy that over if I were you. Your right, the "install" directory is bogus. That doesn't get installed when you use the 'installpkg' command.

You may not need to bother with that script. Looking at your profile I see you're using Slack 9.1, so you'd be more interested in this script:

http://slackware.osuosl.org/slackwar...ssh.SlackBuild

In which the relevant section is simpler (but not much):

Code:

CFLAGS="-O2 -march=i486 -mcpu=i686 -Wall" ./configure --prefix=/usr \
            --sysconfdir=/etc/ssh \
            --without-pam \
            --with-md5-passwords \
            --with-tcp-wrappers \
            --with-default-path=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin \
            --with-ipv4-default \
            --with-privsep-path=/var/empty \
            --with-privsep-user=sshd \
            i486-slackware-linux

You should try to get in the habit of reading the README or README.TXT files, when they're available.

From http://slackware.osuosl.org/slackwar...rce/README.TXT :

Quote:

Many of these packages now have scripts that untar, patch, and compile the
source automatically. These are the 'SlackBuild' scripts.

BTW at the end of the script, it also creates the *.tgz slack package.

So, yes, you can 'd/l everything in the openssh dir and then run openssh.SlackBuild', although you'll have to figure out where to apply your patch. Maybe add a line to the script between where it untars and where it configures.

Enjoy!

Thanks you all, this was very informative for me. I finally feel as though I am begining to get my head around slackware.
I need to update my profile because I am actually running slackware-current, with 2.6.7. I looked around a couple of times
but haven't found a way to do that.

thanks again!!
