in reply to Re^4: How To Link -lperl to Extensions During Build
in thread How To Link -lperl to Extensions During Build

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

    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.

        Here's where I apologize for my lack of knowledge

        And here's where I ask, when you say 'build script' what do you mean? Isn't the ./Configure and make that I;m doing to build perl a script. Or do just want a log of the build?

        NOTE: Went ahead and added the ./Configure && other commands to a shell script and am running it now as build.sh >&1 | tee log

        Also, to clarify, make fails before finishing with the error I posted earlier. I never get to the point where I can run make install
