Hi,

I'm trying to cross-compile libffi for iOS from Debian. I managed to cross-compile it successfully for MacOS (arm64 and x86) using OSX Cross but I'm getting some errors for iOS.

My configure command is:

./configure --host=arm-apple-darwin11 --prefix=$IOS_TOOLCHAIN_ROOT --libdir=$IOS_TOOLCHAIN_ROOT/lib --disable-docs

This is the error I'm getting:


libtool: link: ( cd ".libs" && rm -f "libffi_convenience.la" && ln -s "../libffi_convenience.la" "libffi_convenience.la" )
Undefined symbols for architecture arm64:

ld: symbol(s) not found for architecture arm64

I've raised an issue with full logs here https://github.com/libffi/libffi/issues/821

Anyone know any workaround for this? I need libffi as it's a dependency to Glib.

Thanks
