Hi !
Installed megacmd package under Termux.
megacmd commands under Termux work fine. But not under Emacs shell or eshell:
$ megasimplesync
CANNOT LINK EXECUTABLE "/data/data/com.termux/files/usr/bin/megasimplesync": cannot locate symbol "CrcGenerateTable" referenced by "/system/lib64/libunwindstack.so"...
To reproduce it's enough to run any 'mega-'command.
$ mega-login
and
$ cat ~/megaCmd/megacmdserver.log
CANNOT LINK EXECUTABLE "mega-smd-server": cannot locate symbol "CrcGenerateTable" referenced by "/system/lib64/libunwindstack.so"...
Dont know, if it is misconfiguration or bug.
Relevant information:
Android 10
Downloaded Emacs 30.0.50-29 and Termux 0.118.0 from https://sourceforge.net/projects/android-ports-for-gnu-emacs/files/termux/ with shared user ID and Termux terminal emulator signed with Emacs's signing keys to enable Emacs to make use of the Termux package repositories. Also made the following preparations:
Emacs shell: $ pkg update && pkg upgrade
and added to early-init.el:
(setenv "PATH" (format "%s:%s" "/data/data/com.termux/files/usr/bin" (getenv "PATH")))
(setenv "LD_LIBRARY_PATH" (format "%s:%s" "/data/data/com.termux/files/usr/lib" (getenv "LD_LIBRARY_PATH")))
(push "/data/data/com.termux/files/usr/bin" exec-path)
Other packages e.g. 'pkg' or 'git' work fine under Emacs shell.

Hmm, what if you introduce an entry for /system/lib64 into
LD_LIBRARY_PATH?

Thanks ! Adding /system/lib64 into LD_LIBRARY_PATH made megasumplesync working.
This revealed now the next obstacle. Megasimplesync is a simple process that just stays on after launch. However, all other 'mega-' commands will spawn 'mega-cmd-server' and this will fail under Emacs.
$ mega-sync
[Initiating MEGAcmd server in background. Log:

Unable to connect to service: error=111

The problem seems to be that in Termux and Emacs shell the same executable is linked to the same library (libpcrecpp.so) but in different locations. How can it be solved ?
### Termux ###
$ ldd /data/data/com.termux/files/usr/bin/mega-cmd-server | grep -e "pcrecpp"
libpcrecpp.so => /data/data/com.termux/files/usr/lib/libpcrecpp.so
$ nm -gD /data/data/com.termux/files/usr/lib/libpcrecpp.so | grep -e "_ZN7pcrecpp2RE6no"
00000000000125d0 B _ZN7pcrecpp2RE6no_argE
### Emacs shell ###
$ ldd /data/data/com.termux/files/usr/bin/mega-cmd-server | grep -e "pcrecpp"
(standard input):2: libpcrecpp.so => /system/lib64/libpcrecpp.so
$ nm -gD /system/lib64/libpcrecpp.so | grep -e "_ZN7pcrecpp2RE6no"
$
