[Solved] How to build a module that's not in repos or AUR?

ratcheer · 2014-06-12 19:15:43

I am trying to follow the ABS instructions to build a module. I have the source code from GitHub. However, I cannot find anything that says what to do if the module has not already been built somewhere in Arch. It is not in the abs tree and it is not in the AUR. Maybe I just don't understand the ABS instructions, but I seem to need a PKGBUILD to use it. All I have is the source code for the module.

On Debian, I just run make, then make install. For some reason, that fails in Arch:

gcc: error: -pg and -fomit-frame-pointer are incompatible

The recommendations I have found to work around that error say to keep -fomit-frame-pointer and remove -pg. However, -pg is not actually in the Makefile, it is apparently coming from some default location. If I can't find it, I can't remove it.

In case anyone knows another way to find Arch modules, the one I need is rtl8192du. It is for a USB wireless adapter dongle. https://github.com/lwfinger/rtl8192du

Do you have the headers package installed? I was able to build this without any errors you show.

ratcheer · 2014-06-12 19:31:21

Yes, package linux-headers 3.14.6-1

It also built fine here. If it's not a lack of linux-headers, you may want to check your 'env' output. Do you have any flags set that might be picked up by make?

ratcheer · 2014-06-12 19:37:16

I don't think so. This is a fairly new Arch installation, and I only installed base-devel and linux-headers, yesterday.

Should I look for pg in the env output?

Tim

PS - I don't see anything that looks like any sort of flags or other compiler settings. No "pg" at all.

Are you using the original (master) version, or the kernel version that Larry has made all his fixes to? I'm trying to use the kernel version: rtl8192du-kernel-version

I think that the master version is the one that Realtek open sourced a few years ago.

I built the version you linked to.

Both versions are on the same page, there is a drop down to select one or the other.

ratcheer · 2014-06-12 19:57:28

Ok, the Master version compiles for me, too. So, I guess there is some bug in his revisions.

So, back to the original question. Can I just make and make install this, or do I have to do some kind of ABS build for Arch?

Merry Christmas - Please test it: https://aur.archlinux.org/packages/rtl8192du-git/

ratcheer · 2014-06-12 20:06:02

Thanks very much, graysky (and Trilby).

Trilby · 2014-06-12 20:06:27

I did just get the same error you posted in the OP when I switched to the "kernel-version" branch. Do you need that branch, or will the master branch work? If the master branch will work, graysky's aur package should do it.

(edit: this was crossposted with the above - I take it the master branch will work)

And they need to fix that Makefile... https://github.com/lwfinger/rtl8192du/pull/18

You can build it outside of pacman but that is silly... pacman is Arch It is always best to make a PKGBUILD and build with makepkg/install with pacman.

ratcheer · 2014-06-12 20:49:13

Ok, I built the package from the AUR and installed it. The module is loaded. Now I just have to successfully get through all the systemd startup, wpa_supplicant, etc. The ip link is there and it got an IP address, but something along the way is failing. I just need to go back through all that and try to find what is wrong. I am pretty sure the module is doing just fine.

Thread is marked Solved.

Thanks again,
Tim

grr, while it's great you make the PKGBUILD, graysky, couldn't you have given it a working pkgver function?

It does... It is a git package with a valid pkgver for a git package, no?

The results of `git describe` will not be sequential (nor monotonically increasing which is really the requirement). The wiki suggests using tags, if they are present. But as I rarely use tags myself, I usually use something like the following:

$(git rev-list --count HEAD).$(git describe --always)

This does provide the "describe" hash, but before that is a monotonically increasing number so new commits always show as upgrades.

ratcheer · 2014-06-13 00:03:15

I should open a new thread, but I have been working hard trying to get that new interface actually connected, and I have not been able to. Both the network-wireless@wlp0s26u1u3 and the wpa_supplicant@wlp0s26u1u3 services fail, no matter how hard I try to make sure they are set up correctly.

Quick question - is it ok to have two wireless interfaces running, simultaneously?

That fails for me:

==> Validating source files with md5sums...
    rtl8192du ... Skipped
==> Extracting sources...
  -> Creating working copy of rtl8192du git repo...
Cloning into 'rtl8192du'...
done.
==> Starting pkgver()...
/scratch/rtl8192du-git/PKGBUILD: line 20: 251.e627694: command not found

Trilby · 2014-06-13 02:07:41

That would just be the value - it needs to be echoed or used in some way:

echo "$(git rev-list --count HEAD).$(git describe --always )"

Yeah, sorry, you just kind of hit one of my pet peeves there. git describe really only works for repos with tags.

Personally, I recommend something like

printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"

printf is a built-in, so it's better to use than echo IMO. Putting an "r" in front lets you switch to a pkgver from a tag later without it being a downgrade. And lastly, using git rev-parse --short will always give you the short hash, even if tag is added later.
