in thread How To Link -lperl to Extensions During Build

Unfortunately make failed with the same error after running the simplified configure command.

Regarding the suggestion above, are you suggesting that I run make install even though make fails?

    Well, this is totally convoluted. The build process does not use -lperl when compiling dynamic extensions. To make it happen, I tried something like this: 

    ./Configure -des -Dprefix=/foo -Duseshrplib -Alddlflags="-shared -O2 -
+Wl,-E,-L/foo/lib/perl5/5.20.2/armv7l-linux-android/CORE,-as-needed,-l
+perl,-no-as-needed"
make libperl.so COMMA=, SHRPLDFLAGS='$(subst $(COMMA)-lperl,,$(LDDLFLA
+GS))'
mkdir -p /foo/lib/perl5/5.20.2/armv7l-linux-android/CORE/
cp libperl.so /foo/lib/perl5/5.20.2/armv7l-linux-android/CORE/
make; make install

    Mind you, I don't actually have an android setup to play with...

      Whoa. That IS convoluted. I'll give it a shot...I think I can work around having to make the libperl.so and just use the one I have

      Well, I believe I've finally managed to link libperl with the module that is throwing the error

      readelf output for PL_re.so

      Unfortunately, the original error still persists

      Should I just post this to the perl-porters maillist

        Make a small build script (from configure to install), run it after distclean >& LOG; dump that on some pastebin site.

        Script and link -> cyd's scratchpad.
