From aebf4fb23df2c4ec8857aef05a468991054a58c1 Mon Sep 17 00:00:00 2001 From: Thomas Perale Date: Thu, 19 Sep 2024 18:57:16 +0200 Subject: [PATCH] [sink_flac] missing SWAPS definition On big endian architecture with libflac enabled the following error would happen when cross-compiling aubio with buildroot. ``` [ 75/243] Linking build/tests/test-pitchshift /home/autobuild/autobuild/instance-16/output-1/per-package/aubio/host/bin/../lib/gcc/mips64-buildroot-linux-gnu/13.3.0/../../../../mips64-buildroot-linux-gnu/bin/ld: src/libaubio.so: undefined reference to `SWAPS' collect2: error: ld returned 1 exit status Waf: Leaving directory `/home/autobuild/autobuild/instance-16/output-1/build/aubio-152d6819b360c2e7b379ee3f373d444ab3df0895/build' Build failed ``` Indeed there is a missing definition of the `SWAPS` macro in `/src/io/sink_flac.c` file. This commit copy the `SWAPS` definition from the `/src/io/sink_wavwrite.c` file in `sink_flac.c` to fix this issue.
