[Bug]: ncmpcpp not working

[dxcvvxd]

Problem description

running mpd results in an error CANNOT LINK EXECUTABLE "mpd": cannot locate symbol "eglDestroySyncKHR" referenced by "/system/lib64/libgui.so"... no idea why that happens (especially the egl part, why does it need it?). thanks.

What steps will reproduce the bug?

run mpd get an error

What is the expected behavior?

it should just work

First make sure that LD_LIBRARY_PATH is unset and LD_PRELOAD is sane.

This could be an instance of the duplicate SONAME issue like #13992. But as of now I doubt it, because $PREFIX/bin/mpd does not depend on $PREFIX/lib/libEGL.so in its DT_NEEDED tree, and IIUC the DT_NEEDED entry libEGL.so in /system/lib64/libgui.so should reference /system/lib64/libEGL.so. In fact this issue does not reproduce on my Android 8.1.0 environment.

[xtkoba]

That said, there could be a dynamic linker that behaves differently. I suggest sharing the strace output of mpd command from which we can guess the actual behavior. (Fake ldd command such as libtree cannot be used in this case.)

i tried unsetting the ld lib path, and it worked. but do i have to do that everytime now? speaking of strace, can i output it to a file like a logcat? there's too much errors to fit on one screen

[xtkoba]

It is known that LD_LIBRARY_PATH causes troubles when it contains $PREFIX/lib. In the past LD_LIBRARY_PATH seems to have been used in Termux. But it is not needed now, because Android 7.0 (API 24) or later support DT_RUNPATH. LD_LIBRARY_PATH should be unset unless absolutely necessary.

[xtkoba]

Redirect of strace output can be done as:

strace mpd 2>strace.log

But it is no more needed, as this issue has already been resolved.

Yeah, so issue here is that app variant installed is for android-5 and 6:

TERMUX_APP__PACKAGE_VARIANT=apt-android-5

Install an apt-android-7 variant instead since you are on android-12

What fixed the same error for me (but for ffmpeg) is apt install libandroid-stub
