these are defined and should be available with -lasound?

I am able to reproduce with the following. The LDFLAGS indicate the offending references should be available in via -L/root/openwrt-zipit/staging_dir/target-arm_xscale_musl-1.1.14_eabi/usr/lib

export PATH=$PATH:/root/openwrt-zipit/staging_dir/toolchain-arm_xscale_gcc-5.3.0_musl-1.1.14_eabi/bin

notable that the mplayer in https://mozzwald.com/zipit/index.php?dir=openwrt%2Fbleeding_edge%2Fpackages%2Fzipit_packages%2F is https://mozzwald.com/zipit/openwrt/bleeding_edge/packages/zipit_packages/mplayer_1.0rc4-1_pxa.ipk which is a different version than what we are attempting to build mplayer-r32726

chaseadam commented 3 years ago

modified Makefile to build 1.0rc4 and had same linker issue.

chaseadam commented 3 years ago

I believe the error is the undefined references and not the copy reloc against protected (which appears to be safe to ignore and is related to the binutils version in the toolchain)

chaseadam commented 3 years ago

actual command run by mplayer to reproduce failure

The missing linked library was libsalsa (-lsalsa) which provides the required references in addition to libasound (which is included). Possibly some conflict inside of the linker? Only supports one library which provides reference (and libasound didn't "win")?

Curious because both files are provided by alsa-lib package (source github.com/tiwai/salsa-lib.git) compiled with --enable-libasound

running into a similar alsa linking issue with another package (fluidsynth) which makes me think there is something wrong with build environment (i.e. linker) or alsa-lib package.

Possibly that libasound doesn't contain the .dynsym entry? https://blogs.oracle.com/solaris/post/inside-elf-symbol-tables
