A roundup of my current issues with the alsa-lib repository:

1. No apparent .so (dynamic link) file output.

The configure and make instructions were followed, and no apparent .so resulted:

samiam@samiam-home-pc:~/projects/alsa/alsa-lib-1.1.9$ find . -name *.so samiam@samiam-home-pc:~/projects/alsa/alsa-lib-1.1.9$ find . -name *.a ./src/timer/.libs/libtimer.a ./src/rawmidi/.libs/librawmidi.a ./src/ucm/.libs/libucm.a ./src/topology/.libs/libtopology.a ./src/.libs/libasound.a ./src/hwdep/.libs/libhwdep.a ./src/seq/.libs/libseq.a ./src/mixer/.libs/libmixer.a ./src/control/.libs/libcontrol.a ./src/pcm/.libs/libpcm.a samiam@samiam-home-pc:~/projects/alsa/alsa-lib-1.1.9$ This has made it difficult to debug issues with the library. Using the configure flags does not seem to have an effect on this, IE: ./configure --enable-shared=yes --enable-static=no Linux distributions have libasound.so files in them, so clearly it was possible at some time in the past.

You don't send the more details (config logs etc.) so it's difficult to see what's going wrong with your distribution and configuration. Ubuntu is specific. If you miss something, send us a patch for the review and inclusion.

2. Build instructions are conflicting.

./configure make Does work on this version. This is the standard GNU build method, and I have seen these build instructions around the internet for building alsa. The INSTALL file recommends: ./gitcompile Which also (appears) to work, but no reason appears for why this special file is needed or what it does that is different. I can't get a .so (dynamic library from the build, so I can't check the function of the resulting build. Is there a reason the instructions from ./gitcompile cannot be merged back into the make?

If you compile from the repository, gitcompile should be used, otherwise use the tar ball. The ALSA website allows to generate/download the latest tar ball with the autoconf/automake/libtool scripts bundled.

3. make install brings the system down.

Executing: make install Brought my ubuntu 18.04 sound system down. I had to reinstall Ubuntu to get it to work again.

Distributions usually do own modifications in the default ALSA library configurations. The best way is to use LD_PRELOAD when you compile your own alsa-lib for the debugging to not broke the system's dependencies.

In summary, ALSA is not a development project anymore. It is the "official sound system of Linux" and is part of the kernel. There is a lot of activity on the ALSA list. Cannot some effort be put into professionalizing the repository?

??? I see your frustration, but we are not responsible how distributions adapt the universal code.
