compiling ecl android on MacOSX

[Daniel Kochmański]

Hello,

Did you follow the instructions in INSTALL file? First you have to build
the host ECL (32 bit), and after that the android one withe the provided
cross-config.

./configure ABI=32 CFLAGS="-m32 -g -O2" LDFLAGS="-m32 -g -O2" \
            --prefix=`pwd`/ecl-android-host \
            --disable-longdouble \
            --enable-libatomic=included

Etc. Building for 64 bit should be also possible with some tweaking of
cross config in src/util and configure options.

Mentioned instructions are available here:
https://gitlab.com/embeddable-common-lisp/ecl/blob/develop/INSTALL (and
in the source repository).

Does appstore accept lgpl apps? As far as I understand it doesn't allow
dynamic linkage and static linking will result in covering by lgpl also
your ios app..

If these remarks doesn't help please send more details about build
process you do, host gcc, config.log's, configure options, git commit
etc. I'll try to help then.

Please also note, that android support isn't official yet (I'm
publishing a new release today though 16.1.2, where it already is).

Best regards,
Daniel

PS. I've wrote yesterday from my phone, but I'm not sure if it send the
email properly, sorry for reposting if that's a case.
