The error is due to this line (line 38):

Code:

cd $PRGNAM-$VERSION

Apparently, when the source tarball is untarred in line 37, the resulting directory is not called l2tp-ipsec-vpn-client_1.0.9. Try untarring it yourself from the command line to find out the name of the resulting directory.

The folder name is l2tp-ipsec-vpn after extraction. So, how would I add it?

montagdude · 05-24-2017, 01:56 PM

In that case, you can change line 38 to:

Code:

cd $PRGNAM

or, even more explicitly:

Code:

cd l2tp-ipsec-vpn

The naming convention in the original SlackBuild is a common one that is seen when extracting source. Most of the time, it will be the program name with a dash, then the version, so $PRGNAM-$VERSION usually works. However, not all projects use that naming convention, so sometimes you need to handle it differently in the SlackBuild. In this case, montagdude is correct, you can just simply use cd $PRGNAM to enter the directory. Make sure you update the rm section as well (two lines above), so it can clear out the old folder before it tries extracting again.

There are other times when the source folder is named completely different, or the version might be incompatible with Slackware standards (maybe it has a dash in the version) or maybe it is really long (if you're using a git commit). In those cases, you can either hardcode the values or use different variables (the latter is my personal choice). In those cases, I'll use $SRCNAM and/or $SRCVER, depending on what is needed.

This is because there is no configure file in the source archive. Type "make help" to know the options, and see in https://sourceforge.net/projects/l2t...sec-vpn/1.0.9/ the prerequisites and installation instructions. In this case a SlackBuild template can't be used as is but needs an adaptation as autotools is not used by upstream.

montagdude · 05-24-2017, 05:51 PM

Before or while in the process of creating a SlackBuild script, it's a good idea to build the software manually first. Read any included documentation, like the README and INSTALL files, to see what the authors say about how to build it. Then, once you have a good handle on the process and have built it successfully by just entering the commands on the command line, you can capture the steps in the SlackBuild script. As you are finding, the templates often need adjustment to work with different software. They're not meant to be automatic for the person creating the script.

Also, if you post a link to the source code you are working with, I'm sure people would be able to help you better. I did a quick search but didn't find it.

Edit: actually, on that last point, it looks like Didier found it already. I'll have a look later if I get the chance.

This is what got me started.

I let the tool do the work and tried to edit it myself and got errors. I will follow you and montagdude advice.
Thanks

I looked at what's in the tarball, and unfortunately in this case there isn't any documentation other than what's on the Sourceforge page and `make help` as Didier suggested. It looks like the basic build process will be something like:

Code:

make
make INSTALL_ROOT=$PKG

(While you are testing from the command line, you might want to instead make a local directory to set as INSTALL_ROOT.) From the list of requirements on Sourceforge, it appears that you will need to have ctemplate and cppunit installed from SBo. The rest should be already in Slackware, except I'm not sure about libengine-pkcs11-openssl. Good luck!
