This is an opencl/amd build meaning I didn't enable any intel or nvidia specific options,
this build is also based on ubuntu style package names; That was my intentions.

after running the script for the first time you'll get this error:
```shell
Already up to date.
ERROR: librabbitmq >= 0.7.1 not found using pkg-config
```
This is a problem with librabbitmq pkg-config file. 
Steps to proceed
1) edit the ffmpeg_build.sh script and comment out the lines to rebuild librabbitmq
```bash
cd $sources_dir && \
wget -nc https://github.com/alanxz/rabbitmq-c/archive/v0.10.0.tar.gz && \
tar xzvf v0.10.0.tar.gz && \
cd rabbitmq-c-0.10.0 && \
mkdir -p build && cd build && \
PATH="$bin_dir:$PATH" cmake -DCMAKE_INSTALL_PREFIX="$build_dir" -DBUILD_SHARED_LIBS=OFF -DBUILD_STATIC_LIBS=ON -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF ../ && \
PATH="$bin_dir:$PATH" cmake --build . --config Release --target install
```
becomes
```bash
# cd $sources_dir && \
# wget -nc https://github.com/alanxz/rabbitmq-c/archive/v0.10.0.tar.gz && \
# tar xzvf v0.10.0.tar.gz && \
# cd rabbitmq-c-0.10.0 && \
# mkdir -p build && cd build && \
# PATH="$bin_dir:$PATH" cmake -DCMAKE_INSTALL_PREFIX="$build_dir" -DBUILD_SHARED_LIBS=OFF -DBUILD_STATIC_LIBS=ON -DBUILD_EXAMPLES=OFF -DBUILD_TESTS=OFF ../ && \
# PATH="$bin_dir:$PATH" cmake --build . --config Release --target install
```
so that the edits that you do in the next steps are not overwritten
then 
edit $basedir/build/lib/x86_64-linux-gnu/pkgconfig/librabbitmq.pc

change
```bash
Name: rabbitmq-c
Description: An AMQP 0-9-1 client library
Version: 0.10.0
URL: https://github.com/alanxz/rabbitmq-c
Requires.private: openssl
Libs: -L${libdir} -lrabbitmq
Libs.private: rt;-pthread
CFlags: -I${includedir}
```
by editing Libs.private;
to "-t -pthread"

```bash

```
I created an issue: https://github.com/alanxz/rabbitmq-c/issues/642

After you make this edit, rerun ffmpeg_build.sh script

you might also get an error for libflite
if that's the case, you need to edit ffmpeg-git/configure

change this line
```bash
flite_extralibs="-lflite_cmu_time_awb -lflite_cmu_us_awb -lflite_cmu_us_kal -lflite_cmu_us_kal16 -lflite_cmu_us_rms -lflite_cmu_us_slt -lflite_usenglish -lflite_cmulex -lflite"
```
to this line

```bash
flite_extralibs="-lflite_cmu_time_awb -lflite_cmu_us_awb -lflite_cmu_us_kal -lflite_cmu_us_kal16 -lflite_cmu_us_rms -lflite_cmu_us_slt -lflite_usenglish -lflite_cmulex -lflite -lasound"
```
