From 8a9ea7ce0789f9950b796fa11cf54580d7554266 Mon Sep 17 00:00:00 2001 From: Pavel Galkin Date: Fri, 28 Mar 2025 18:41:44 -0300 Subject: [PATCH] ALSA: Fix undefined symbols during static compilation These were undefined when linking with the -static flag on: 1. Alpine Linux v3.21 x86_64 2. Debian GNU/Linux 12 (bookworm) aarch64 In both cases I had to manually compile alsa-lib as a static library because the systems have only .so versions. I did it with: cd path/to/alsa-libs ./gitcompile static Tested with alsa-libs 1.12.2 and 1.12.3. It's possible to reproduce the errors like this: clang -static -DMA_NO_RUNTIME_LINKING -DMA_ENABLE_ONLY_SPECIFIC_BACKENDS -DMA_ENABLE_ALSA -DMA_DEBUG_OUTPUT -Wall -Wextra -g3 simple_playback_sine.c -o build/miniwave -fcolor-diagnostics -ferror-limit=2 -fuse-ld=lld -I../ -L/home/antharas/code/alsa-lib/src/.libs/ -lasound However, even though it compiles I can't verify that everything works. 1. Alpine has musl which doesn't support runtime linking when compiling with -static. So even though I disabled it for miniaudio.h, libasound.a itself uses dlopen on libasound_module_pcm_pipewire.so. 2. Debian uses glibc so it supports it but fails because my machine is a VPS that doesn't have a soundcard. No big deal, I don't really need to statically link, it was just something I stumbled upon. Also these are currently unused: _snd_pcm_hw_params_set_rate_minmax ma_timer_init ma_timer_get_time_in_seconds ma_device__on_notification_rerouted --- miniaudio.h | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/miniaudio.h b/miniaudio.h index 06e99767..0b143f61 100644 --- a/miniaudio.h +++ b/miniaudio.h @@ -26688,6 +26688,9 @@ typedef snd_pcm_channel_area_t ma_snd_pcm_channel_area_t; typedef snd_pcm_chmap_t ma_snd_pcm_chmap_t; typedef snd_pcm_state_t ma_snd_pcm_state_t; +/* snd_pcm_state_t */ +#define MA_SND_PCM_STATE_XRUN SND_PCM_STATE_XRUN + /* snd_pcm_stream_t */ #define MA_SND_PCM_STREAM_PLAYBACK SND_PCM_STREAM_PLAYBACK #define MA_SND_PCM_STREAM_CAPTURE SND_PCM_STREAM_CAPTURE @@ -26883,6 +26886,7 @@ typedef int (* ma_snd_pcm_hw_params_set_channels_minmax_proc) ( typedef int (* ma_snd_pcm_hw_params_set_rate_resample_proc) (ma_snd_pcm_t *pcm, ma_snd_pcm_hw_params_t *params, unsigned int val); typedef int (* ma_snd_pcm_hw_params_set_rate_proc) (ma_snd_pcm_t *pcm, ma_snd_pcm_hw_params_t *params, unsigned int val, int dir); typedef int (* ma_snd_pcm_hw_params_set_rate_near_proc) (ma_snd_pcm_t *pcm, ma_snd_pcm_hw_params_t *params, unsigned int *val, int *dir); +typedef int (* ma_snd_pcm_hw_params_set_rate_minmax_proc) (ma_snd_pcm_t *pcm, ma_snd_pcm_hw_params_t *params, unsigned int *min, int *mindir, unsigned int *max, int *maxdir); typedef int (* ma_snd_pcm_hw_params_set_buffer_size_near_proc)(ma_snd_pcm_t *pcm, ma_snd_pcm_hw_params_t *params, ma_snd_pcm_uframes_t *val); typedef int (* ma_snd_pcm_hw_params_set_periods_near_proc) (ma_snd_pcm_t *pcm, ma_snd_pcm_hw_params_t *params, unsigned int *val, int *dir); typedef int (* ma_snd_pcm_hw_params_set_access_proc) (ma_snd_pcm_t *pcm, ma_snd_pcm_hw_params_t *params, ma_snd_pcm_access_t _access); @@ -28649,8 +28653,9 @@ static ma_result ma_context_init__alsa(ma_context* pContext, const ma_context_co ma_snd_pcm_hw_params_get_format_mask_proc _snd_pcm_hw_params_get_format_mask = snd_pcm_hw_params_get_format_mask; ma_snd_pcm_hw_params_set_channels_proc _snd_pcm_hw_params_set_channels = snd_pcm_hw_params_set_channels; ma_snd_pcm_hw_params_set_channels_near_proc _snd_pcm_hw_params_set_channels_near = snd_pcm_hw_params_set_channels_near; + ma_snd_pcm_hw_params_set_channels_minmax_proc _snd_pcm_hw_params_set_channels_minmax = snd_pcm_hw_params_set_channels_minmax; ma_snd_pcm_hw_params_set_rate_resample_proc _snd_pcm_hw_params_set_rate_resample = snd_pcm_hw_params_set_rate_resample; - ma_snd_pcm_hw_params_set_rate_near _snd_pcm_hw_params_set_rate = snd_pcm_hw_params_set_rate; + ma_snd_pcm_hw_params_set_rate_proc _snd_pcm_hw_params_set_rate = snd_pcm_hw_params_set_rate; ma_snd_pcm_hw_params_set_rate_near_proc _snd_pcm_hw_params_set_rate_near = snd_pcm_hw_params_set_rate_near; ma_snd_pcm_hw_params_set_rate_minmax_proc _snd_pcm_hw_params_set_rate_minmax = snd_pcm_hw_params_set_rate_minmax; ma_snd_pcm_hw_params_set_buffer_size_near_proc _snd_pcm_hw_params_set_buffer_size_near = snd_pcm_hw_params_set_buffer_size_near; @@ -28702,9 +28707,9 @@ static ma_result ma_context_init__alsa(ma_context* pContext, const ma_context_co ma_snd_pcm_info_proc _snd_pcm_info = snd_pcm_info; ma_snd_pcm_info_sizeof_proc _snd_pcm_info_sizeof = snd_pcm_info_sizeof; ma_snd_pcm_info_get_name_proc _snd_pcm_info_get_name = snd_pcm_info_get_name; - ma_snd_pcm_poll_descriptors _snd_pcm_poll_descriptors = snd_pcm_poll_descriptors; - ma_snd_pcm_poll_descriptors_count _snd_pcm_poll_descriptors_count = snd_pcm_poll_descriptors_count; - ma_snd_pcm_poll_descriptors_revents _snd_pcm_poll_descriptors_revents = snd_pcm_poll_descriptors_revents; + ma_snd_pcm_poll_descriptors_proc _snd_pcm_poll_descriptors = snd_pcm_poll_descriptors; + ma_snd_pcm_poll_descriptors_count_proc _snd_pcm_poll_descriptors_count = snd_pcm_poll_descriptors_count; + ma_snd_pcm_poll_descriptors_revents_proc _snd_pcm_poll_descriptors_revents = snd_pcm_poll_descriptors_revents; ma_snd_config_update_free_global_proc _snd_config_update_free_global = snd_config_update_free_global; pContext->alsa.snd_pcm_open = (ma_proc)_snd_pcm_open;
