: fuck unrar
|
||||||
|
|
||||||
|
I run Chimera Linux, an Alpine-based operating system still in its very early
|
||||||
|
stages but stable enough that I trust it for my meager, mostly console and X11
|
||||||
|
based workflow. It can run a C compiler, so good enough for me. The only issue
|
||||||
|
is, despite being based on Alpine, a popular operating system not for desktop
|
||||||
|
but for embedded environments like containers, for which a lot of software is
|
||||||
|
packaged and available in system repositories, Chimera does not have a lot of
|
||||||
|
packages. I'm going to package UNRAR, a non-free ("freeware") tool that has no
|
||||||
|
dependencies aside from the C++ standard library, to get a feel for Alpine
|
||||||
|
packaging.
|
||||||
|
|
||||||
|
UNRAR is an almost delightful little tool with the unfortunate, heinous problem
|
||||||
|
of being non-free, and its license forbidding the use of the provided source
|
||||||
|
code for reimplementation - otherwise I would just rewrite it in sane C89
|
||||||
|
without encumbrence. But we don't need to read the source code in order to
|
||||||
|
compile the C++.
|
||||||
|
|
||||||
|
The Alpine Wiki section on Creating an Alpine package says to apk add
|
||||||
|
alpine-sdk but Chimera has no such thing so hopefully that's fine. It says to
|
||||||
|
check out the aports tree but I don't want to put my packages upstream (dealing
|
||||||
|
with large software projects is tiresome and I know Chimera is in a constant
|
||||||
|
state of flux).
|
||||||
|
|
||||||
|
I did this:
|
||||||
|
|
||||||
|
# mkdir -p /var/cache/distfiles
|
||||||
|
# chmod a+w /var/cache/distfiles
|
||||||
|
|
||||||
|
I now need abuild-keygen according to the wiki but it isn't installed.
|
||||||
|
$ apk search abuild-keygen
|
||||||
|
pulled up nothing. Nor did a package contents search. Maybe it's fine? On a
|
||||||
|
whim I searched cbuild* in the contents search and found apk:base-cbuild-progs.
|
||||||
|
# apk add base-cbuild-progs
|
||||||
|
(1/1) Installing base-cbuild-progs (0.1-r2)
|
||||||
|
OK: 2083 MiB in 896 packages
|
||||||
|
|
||||||
|
On the Chimera Linux website I found the Chimera-specific packaging stuff.
|
||||||
|
There is a cports repository with Packaging.md but it's kind of long so I'll
|
||||||
|
use it as a reference while following the less complete Alpine guide. This is
|
||||||
|
the rat bastard approach to software but I am doing this for my own uses and
|
||||||
|
for pleasure and I don't wanna spend five hours contributing to this project
|
||||||
|
right now because I am tired.
|
||||||
|
|
||||||
|
I need newapkbuild but don't have it so I'll try to find the default template
|
||||||
|
on-line or go off an existing thingy.
|
||||||
|
|
||||||
|
I found contrib/jq/template.py so I'll copy that.
|
||||||
|
|
||||||
|
pkgname = "unrar"
|
||||||
|
|
||||||
|
What's the pkgver?
|
||||||
|
|
||||||
|
$ cd /usr/local/src/unrar
|
||||||
|
-sh: 5: cd: can't cd to /usr/local/src/unrar
|
||||||
|
$ cd /usr/local/src
|
||||||
|
$ ls
|
||||||
|

|
||||||
|

|
||||||
|

|
||||||

|
||||||
|

|
||||||

|
||||||
|

|
||||||
|

|
||||||
|
|
||||||
|
I guess it doesn't matter because the download link says 6.12.2, so I'll just
|
||||||
|
put that. Maybe I have a different version. I don't care.
|
||||||
|

# license is tricky. how does alpine do it?
|
||||||
|
# checked. alpine does not do it, because unrar is non-free
|
||||||
|
|
||||||
|
What is this license, anyway?
|

[ 9:52 PM] trinity: bsdtar WORKS ON FUCKING RAR FILES?????
|
||||||
|
[ 9:52 PM] trinity: 7z DID NOT DO THE JOB BUT bsdtar DID?
|
||||||
|
[ 9:58 PM] [...]: that's shocking actually wtf
|
||||||
|
[10:03 PM] trinity: bsdtar errors out too :(
|
||||||
|
[10:03 PM] trinity: no unrar package for chimera
|
||||||
|
[10:04 PM] trinity: not pkgsrcing it because 500 deps compiling on a raspberry
|
||||||
|
pi
|
||||||
|
[10:18 PM] trinity: figured out how to build unrar from source. NO DEPS!
|
||||||
|
[10:18 PM] trinity: for nonfree software it sure is easy build
|
||||||
|
[10:21 PM] [...]: why somebody would ever use a nonfree compressed archive
|
||||||
|
format is beyond me
|
||||||
|
[10:21 PM] [...]: .tar.gz is standard. .arc and .zpaq are fucking insane with
|
||||||
|
compression ratios.
|
||||||

|
||||||
|
|
||||||
|
[12:12 AM] trinity: i really dont understand use of rar
|
||||||
|
[12:12 AM] trinity: as mainstream archives go 7z is a lot better
|
||||||
|
[12:13 AM] [...]: yeah
|
||||||
|
[12:13 AM] [...]: I see rar used a lot in piracy stuff and I'm not rlly sure
|
||||||
|
what that's about
|
||||||
|
[12:19 AM] [...]: wait i can use bsdtar for unrar
|
||||||
|
[12:19 AM] [...]: pog
|
||||||
|
[12:20 AM] trinity: unrar works better
|
||||||
|
[12:20 AM] [...]: i dont have any way to unrar things atm because i
|
||||||
|
uninstalled unrar for being nonfree
|
||||||
|
[12:20 AM] trinity: unrar for nonfree software is not very bad. i oughtta just
|
||||||
|
rewrite it in C
|
||||||
|
[12:20 AM] [...]: someone has done that
|
||||||
|
[12:21 AM] [...]: you could build on their work
|
||||||
|
[12:21 AM] trinity: wouldnt that be free software
|
||||||
|
[12:21 AM] trinity: fuck actually i dont like unrar's everything i should just
|
||||||
|
make my own unrar based on the nonfree code
|
||||||
|
[12:22 AM] trinity: license forbids this :(
|
||||||
|
[12:22 AM] [...]: violating proprietary licenses is based
|
||||||
|
[12:23 AM] [...]: unrar (super illegal edition!!)
|
||||||
|
[12:23 AM] [...]: it doesnt currently work afaik. it works for older rar files
|
||||||
|
[12:24 AM] trinity: is there much difference
|
||||||
|
[12:26 AM] trinity: REing rar seems to not be that useful because soon everyone
|
||||||
|
that uses it will be dead and everyone will be using
|
||||||
|
something open
|
||||||
|
[12:27 AM] [...]: idk
|
||||||
|
[12:27 AM] [...]: rarverse engineering
|
||||||
|
[12:28 AM] [...]: ill probably just write a wrapper for bsdtar that can be
|
||||||
|
called on rar files
|
||||||
|
[12:28 AM] [...]: rawrverse engineewing~ >.<
|
||||||
|
[12:29 AM] trinity: because unrar, while proprietary, can be compiled with any
|
||||||
|
C++ compiler and make tool and works with standard POSIX
|
||||||
|
APIs, i don't think the ability to decompress will be
|
||||||
|
threatened any time soon. best rebellion is just to decomp
|
||||||
|
and recomp rar files into better formats
|
||||||
|
[12:30 AM] trinity: did you know that rawr means i love you in dinosaur
|
||||||
|
|
||||||
|
AAAA I give up.
|
||||||
|
|
||||||
|
Chimera docs say very little about -doc packages, which should have the license
|
||||||
|
file for the current software if the license is custom, which UnRAR's is. So
|
||||||
|
license.txt should go in "$pkgdir"/usr/share/licenses/$pkgname/COPYING
|
||||||
|
|
||||||
|
Wait I get it. The cbuild will automagically add that license to the -doc
|
||||||
|
package for me. Nevermind. So I just have to
|
||||||
|
|
||||||
|
license = "custom"
|
||||||
|
|
||||||
|
def post_install(self):
|
||||||
|
self.install_license("license.txt")
|
||||||
|
|
||||||
|
url = "https://www.rarlab.com/rar_add.htm"
|
||||||
|
source = f"https://www.rarlab.com/rar/unrarsrc-{pkgver}.tar.gz"
|
||||||
|
|
||||||
|
Okay, this would probably work, but I don't care to actually button this up and
|
||||||
|
PR it so that's all it will be. Here's how it looks in my src/Makefile which
|
||||||
|
works better for my uses:
|
||||||
|
|
||||||
|
# depends on
|
||||||
|
# apk:g++
|
||||||
|
$(PREFIX)/bin/unrar:
|
||||||
|
git clone https://github.com/pmachapman/unrar.git "$(PREFIX)"/src/unrar
|
||||||
|
$(MAKE) -C "$(PREFIX)"/src/unrar
|
||||||
|
$(INSTALL) -Dm0755 "$(PREFIX)"/src/unrar/unrar "$(PREFIX)"/bin/unrar
|
||||||
|
|
||||||
|
To be honest, I copied the install(1) permission from somewhere else. Not sure
|
||||||
|
if 0755 is the best config. But I don't care because FUCK UNRAR!!!!
