Introduction to libsndfile

Libsndfile is a library of C routines for reading and writing files containing sampled audio data.

[Note]

Note

This version of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable version of the System V books.

Package Information

libsndfile Dependencies

Recommended

FLAC-1.5.0, Opus-1.6.1, and libvorbis-1.3.7

Optional

alsa-lib-1.2.15.3, LAME-3.100, mpg123-1.33.4, and Speex-1.2.1

Installation of libsndfile

Fix building with GCC-15: 

sed -i '/typedef enum/,/bool ;/d' src/ALAC/alac_{en,de}coder.c

Install libsndfile by running the following commands: 

./configure --prefix=/usr    \
            --docdir=/usr/share/doc/libsndfile-1.2.2 &&
make

If running the test suite, disable the Opus tests which would fail with the recent Opus release and cause the test suite to bail out early: 

sed '/ogg_opus/,+1s/HAVE_[A-Z_]*/0/' -i tests/lossy_comp_test.c

To test the results, issue: make check.

Now, as the root user: 

make install
