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: 
/data/data/org.gnu.emacs/files/.megaCmd/megacmdserver.log]
Unable to connect to service: error=111
Please ensure mega-cmd-server is running
Failed to create socket for registering for state changes

$ cat ~/.megaCmd/megacmdserver.log
CANNOT LINK EXECUTABLE "mega-cmd-server": cannot locate symbol 
"_ZN7pcrecpp2RE6no_argE" referenced by 
"/data/data/com.termux/files/usr/bin/mega-cmd-server"...

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"
  $
