A shared library as this is what's needed for usage of the LCL. See also
examples/androidlcl of a current Lazarus version (at least 1.0).

Yes. The binutils with version 2.19 crashed without reasons and on the
Lazarus forum there were suggestions to add "-FLlibdl.so". I had added that
to the fpc.cfg and forgot to remove it when I cleanly rebuild with the 2.21
binutils. This was all before I started to write you.

"it" was the "-FLlibdl.so" and "the library" is the one I'm trying to
build. Sorry for the confusion.

I will try that.
