[CinCV TNG] Building in Gentoo; Was: Re: Cinelerra 5.1: Two bugs

Tue Apr 26 10:06:48 CEST 2016

Hello again (actually I forgot to greet previously, but my respect is sincere
for the Cinelerra team ;-) )!

I read a few times over your emails (and I hope there won't be 
new to discover in the meantime so I don't lose track ;-( ...I'm pretty
slow, but thoroughly I really try to do things --if they don't show to
be too difficult for me...).

Both of your mails are here, the previous is quoted twice. It's simple
for me to respond the old way, btwn the quoted lines.

Very glad if we get the list for emerge'ing and it gets included in the
bld_prepare.sh script in your git!

I'm still preparing, kind of getting to understand how I should do it
this new time, but from scratch, not a recompile like there were a few
previously.

I already went through the:
https://git.cinelerra-cv.org/gitweb?p=CinelerraCV.git;a=blob_plain;f=README.BUILD;hb=refs/heads/master
and, like I wrote in:
http://git0-miro/CroatiaFidelis/foss/gentoo/cinelerra-out-of.php

In my case only:

emerge -tuDN libavc1394 libiec61883

was needed. I had all the other programs from that main repo README.

And also the:

libesd (esound = 0.2.28)

from that README is not needed in my case (pure alsa here).

No, almost 300MB. See below.

It's email, and it split it, but this command:
git clone --depth 1 \
	"git://git.cinelerra-cv.org/goodguy/cinelerra.git" cinelerra5

should not be split (if any other readers are following).

And I reached here. See further below.

Unless your branch, Good Guy is very different than the main branch
(which I don't expect, but don't know, so pls do tell if the procedure
for configure/make/make install is very different than for the main git
branch!), the following may hold.

I know the below (installing all in /opt) is likely simpler, but in my
heavily hardened but rather simple and as old-unix-style as possible
system (such as no poetterware --such as systemd--, actually not even
dbus, a program that some of us in the *nix world just don't trust),
that (installing all in /opt) might mean more gradm system-learning...

And I developed for myself this out-of-portage method of install by
which I keep really good track of what I install into my system...

I used:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var \
	--with-x --with-buildinfo=git

Have a look at the list of files that my first, and the second install
contain. It's the same list:

http://www.croatiafidelis.hr/foss/gentoo/cinelerra-160425-logs/cinelerra-cv_160424_2253_make_install.ls-1
(marked with the time of the first install, but the first install:
http://www.croatiafidelis.hr/foss/gentoo/cinelerra-160425-logs/cinelerra-cv_160424_2253_make_install.ls-1.ls-l
and the second instaLL:
http://www.croatiafidelis.hr/foss/gentoo/cinelerra-160425-logs/cinelerra-cv_160425_1019_make_install.ls-l
have timestamps for files at the time of their different install.

I'd like to keep to  --prefix=/usr and  --localstatedir=/var
and such, and not opt, because with my method I can easily remove the
entire install. I verified that it worked fine on Lurker, another
program that Gentoo does not offer in Portage:
Need help creating ebuild for "lurker" (not mine, the title)

Thanks. I hope I haven't been difficult with my understanding and
planning.

BTW., there's been a little more talk at grsecurity forums:
https://forums.grsecurity.net/viewtopic.php?f=3&t=4453&p=16226#p16225
on the issue that probably awaits me in my compile from scratch from
your git branch...
