I am interested in mod-script-pipe. What I need to do in order to see it in preferences->modules. I currently have released version of 2.2.0 audacity on my Ubuntu Linux. When I enter “modules” in preferences it says “No modules were found”. Do I need to compile entire audacity for this or just the mod-script-pipe.
Both, Audacity and mod-script-pipe.
When running “configure”, be sure to use the “–with-mod-script-pipe” option.
After building Audacity you will need to manually move mod-script-pipe.so into a location where Audacity can find it. There’s a couple of options where to put it, but I’d recommend putting it in:
Do I need to copy these mod-script-pipe*.l* file to ~/.audacity-files/modules/
Also I see another directory in my home
~/.audacity-data is that okay?
I am asking these question as I couldn’t test the newly compiled audacity. When I try to run it, it is giving this error and I am in the process of fixing this.
./audacity: error while loading shared libraries: libwx_baseu_xml-3.1.so.1: cannot open shared object file: No such file or directory
The current version 2.3.0 has --mod-script-pipe option in the configure script but in the earlier versions I am not seeing anything specific to mod-script-pipe in the “configure” script. Even if I configure with --with-mod-script-pipe, the mod-script-pipe is not getting built. I am not seeing anything in lib-src. As I am working on Linux I don’t want to use 2.3.0 version as it is not stable. I am using the source from this link
Here’s a short version of how I build Audacity on Ubuntu 16.04:
Starting from the root of the Audacity source tree:
mkdir build
cd build
mkdir "Portable Settings"
../configure --with-lib-preference="local system" --with-ffmpeg="system" --disable-dynamic-loading --with-mod-script-pipe 2>&1 | tee build.log
make -j8 2>&1 | tee -a build.log
Note that I’m building on an 8 core machine. If your computer has less cores, change the “-j8” in the last line to match the number of CPU cores.
When it completes (without errors), Audacity can be launched:
./audacity
If you need to scrap the build and start again, you can just delete the “build” directory.
When that works, we can build mod-script-pipe. Note that this must be built on the same day as building Audacity.
cd lib-src/mod-script-pipe
make -j8
Assuming that completed without error, open
.../build/lib-src/mod-script-pipe/.libs/
and you should see a bunch of files.
Copy all of them into:
~/.audacity-files/modules/
Restart Audacity and enable mod-script-pipe in Preferences > Modules
Close and restart Audacity.
Thanks for the detailed explanation. Please note I have been compiling audacity with different versions. I understand Linux fairly well. I have been following the same procedure you mentioned for the build. Other than the version 2.3.0 in all the earlier versions lib-src/mod-script-pipe directory is not getting created after the audacity configure+make.
Anyway I followed the same command you suggested. It is building audacity successfully but I don’t see the directory lib-src/mod-script-pipe. The behaviour is exactly same as what I was seeing earlier. I built here audacity version 2.2.2 on Ubuntu Linux 18.04.
…/configure --with-lib-preference=“local system” --with-ffmpeg=“system” --disable-dynamic-loading --with-mod-script-pipe 2>&1 | tee build.log
make 2>&1 | tee -a build.log
I am only seeing these files/directories after building audacity in lib-src

Thank you very much for clarifying. I didn’t know that I had to copy the files to lib-src/mod-script-pipe. Now everything compiled for version 2.2.2
I was confused from day one as to why 2.3.0 creates the mod-script-pipe directory automatically and other versions don’t. Anyway thanks for your awesome help.
We are slowly moving towards including mod-script-pipe as part of the standard Audacity package.
Currently I would recommend it for geeks, enthusiasts and “advanced users”, that understand that this feature is still under development and subject to change.
Mod-script-pipe should NOT be used on a shared network environment, such as on a server that has public access. (See the warnings near the top of this page in the alpha-manual: https://alphamanual.audacityteam.org/man/Scripting). Because of this, even when mod-script-pipe is shipped, it will be disabled by default.
