Hi, Thanks for your trial to build alsa-gobject ;)

The cause of error is building for Linux kernel version 4.6 or before. The missing 'card' and 'pid' members in 'struct snd_seq_client_info' were added by this patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a1ce94d03bfd $ git name-rev --tags a1ce94d0 a1ce94d0 tags/sound-4.6-rc1~21 I'm awareless of the change and use Linux kernel v4.18 or later for development. Build test on CI platform is setup to build under below environments[1]: - Fedora 32 (Linux v5.6) - Ubuntu 19.10 (Linux v5.4) Is it possible to upgrade your kernel up to v4.6 or later? I could add conditional macro to build the issued code according to kernel version, but it can increase maintainance cost of the library... > I tried to build as well, but get another error again. > > root@darkstar:/tmp/alsa-gobject/build# meson build > > ERROR: Neither directory contains a build file meson.build. > > There was't meson.build file actually: > > root@darkstar:/tmp/alsa-gobject/build# ls > build.ninja doc/ meson-logs/ meson-uninstalled/ > tests/ > compile_commands.json meson-info/ meson-private/ src/ > > I'm ashamed to say I have no idea where I went wrong in the above steps. > But I would appreciate any help or suggestion to resolve these errors. Once building the 'build' directory, you just run 'ninja' command in the directory.
