in reply to How To Link -lperl to Extensions During Build

If you really, really want to go that way, I think the -Dldflags or -Aldflags (for -Append) options to ./Configure are the way. But are you sure you don't want to use the cctools? They come with a shell window and make, gcc and all the shell utilities and at least I didn't need to jump through too many hoops when compiling Perl for Android.

The configure command I use to compile Perl 5.21.11 on Android is:

  sh ./Configure -Dprefix=/storage/sdcard0/perl
    -des
    -Dusedevel
    -Dprefix=/data/local/perl-5.21.11/
    -Dsysroot=/data/data/com.pdaxrom.cctools/root/cctools
    -Alibpth=/system/lib /vendor/lib
    -Dman1dir=none
    -Dman3dir=none
    -Dsite1man=none
    -Dsite3man=none
    -Dvendorman1=none
    -Dvendorman3=none
    -DNO_LOCALE

Also you might want to take a look at App::staticperl, which will try to compile a perl with all libraries linked statically into it.

    KBOX is a shell environment that emulates a Linux filesystem...make, gcc and a ton of other utilites are included.

    Its one quirk is that it only supports dynamic linking to libc...that plus Android's broken linker means any ext that uses symbols from libperl.so needs to be linked to it.

    Will using -Aldflags propagate down to the part of the build where extensions are compiled?

    Additionally, -Aldflags doesn't seem to work...

      I think you will have to show some of your output how -Aldflags fails, and maybe also how installing modules fails after you've compiled your Perl.
