You're trying to generate an executable or a shared library (.so)?

You mean the one with the full path has been added in error?

What is "it" exactly? Which library cannot be linked? What's the error?

Just checked, for libraries "/system/bin/linker" should be added
automatically (compiler/systems/t_android.pas)

Looks okay, but I will see if I can find these tests I was mentioning.
That stuff is on a different computer though.

Looking through compiler/systems/t_android.pas, you may want to try
commmenting line 343, the one that adds info.Dynamiclinker to the input
files. Looks wrong.
(system/bin/linker is passed to ld later as --dynamic-linker option
later anyway).
