Hello SOX gurus,
I'm attempting to build an Amazon Linux binary of SOX with LADSPA plugin
support, starting with helpful instructions found here for the SOX part:
http://marcelog.github.io/articles/static_sox_transcoding_lambda_mp3.html

I was able to follow the instructions with minor tweaks and also found a
great introduction on installing LADSPA here:
http://archive.oreilly.com/pub/a/linux/2001/02/02/ladspa.html

So far I've made some progress... I think, with this:

====
sudo su
wget http://www.ladspa.org/download/ladspa_sdk.tgz
tar zxf ladspa_sdk.tgz
cd ladspa_sdk/src
#update all "-mkdirhier" to "mkdir -p" in makefile, then:
make
make install
export LADSPA_PATH=/usr/lib/ladspa
====

After that, I run the configure file when preparing to build SOX. I'm
getting this output in terminal:

====
...
BUILD OPTIONS
Debugging build............no
Distro name ...............not specified!
Dynamic loading support....no
Pkg-config location........$(libdir)/pkgconfig
Play and rec symlinks......yes
Symlinks enabled...........yes

OPTIONAL DEVICE DRIVERS
ao (Xiph)..................no
alsa (Linux)...............no
coreaudio (Mac OS X).......no
sndio (OpenBSD)............no
oss........................yes
pulseaudio.................no
sunaudio...................no
waveaudio (MS-Windows).....no

OPTIONAL FILE FORMATS
amrnb......................no
amrwb......................no
flac.......................no
gsm........................yes (in-tree)
lpc10......................yes (in-tree)
mp2/mp3....................no

opus.......................no
sndfile....................no
wavpack....................no

OTHER OPTIONS
ladspa effects.............no
magic support..............no
png support................no
OpenMP support.............yes, -fopenmp
...
====

Note how ladspa effects is set to "no". I can confirm that there are a few
default ones in LADSPA_PATH; sine.so, noise.so, filter.so, etc.

Do you have an idea how I can include LADSPA support in my binary? I've
never used a related plugin with SOX. If I could get this to work on Amazon
Linux, I can create cool vocal effects for my automated-ish music project.

If you could help me succeed, I'll respond with a customized, automated
thank you song from my project. :D

Many thanks in advance!

Kind regards,

Chris
