<div bgcolor="#ffffff" text="#000000"> <tt>I am making a
Cin_20240630 build by myself for the OS
UbuntuStudio_16.04_LTS_64bit.<br>
I read in the MailingLists thanks to Phyllis and
Andrew_R, I need to use specific instruction.<br>
<br>
From What I understand, with Cin_20240630 the steps
are:<br>
1) cd to "cinelerra-5.1" directory<br>
2) make clean<br>
3) export FFMPEG_EXTRA_CFG="--disable-decoder=vvc"<br>
( before running autogen.sh / configure / make )<br>
4) patch -p1 < alt_shortcuts.patch<br>
( to use standard shortcuts )<br>
5) ./autogen.sh<br>
6) ./configure --with-single-user
--without-shuttle-usb \<br>
--without-vaapi --without-vdpau \<br>
--disable-dav1d \<br>
--enable-libaom=no<br>
( "--enable-libaom=no" added, without double
quote )<br>
7) make 2>&1 | tee log<br>
8) grep "\*\*\*.*error" -ai log<br>
( Check for obvious build errors )<br>
9) make install<br>

I am ignorant in Linux, so I would like to understand
if the instruction<br>

write something in somewhere or not.<br>

</div>
<div dir="auto">it passed to internal ffmpeg's configure script,
so you can look into thirdparty/ffmpeg-7.0/ffbuild (if I
remember correctly) and read big log there, after build
process come to it. <br>

Thank you, Andrea_R! I found it where you indicated.<br>
But I don't understand, how <b>export</b> instruction knows where
to go,... how does it know the path where to write that parameter?<br>
Sorry, It is a stupid question, here, but I would like to
understand.<br>

Because my Operating System is UbuntuStudio_16.04, is
there a way to build Cinelerra-GG using an old FFMPEG
and/or libaom?<br>

<div dir="auto">how old, exactly? Right now it should be
buildable with ffmpeg6.x/7.0 (tested), I also removed
buildability with ffmpeg-4.4 because I had some crashes during
ff_* filter tests on my 32bit Slackware. ffmpeg 5.x not tested

I am thinking to FFMPEG-4.3 and libaom-v3.4.0. But, maybe it doesn't
make sense.
