Hi @saudet, I tried the library on my mac m1 but it fails at runtime with:

Checking for new libpostal data file...
libpostal data file up to date
Checking for new libpostal parser data file...
libpostal parser data file up to date
Checking for new libpostal language classifier data file...
libpostal language classifier data file up to date
dyld[38785]: missing symbol called

Apparently, this is a sign the architecture of the library is incorrect. However, if I unpack the jar, the library looks ok

otool -hv libpostal.1.dylib
libpostal.1.dylib:
Mach header
      magic  cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64   X86_64        ALL  0x00       DYLIB    14       1696   NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS

do you have an idea of what went wrong?

Thanks,
Guillaume

It's saying "X86_64", doesn't this need to be "ARM64"?

[MasseGuillaume]

oh you are right, I was looking at the other dynamic library where the architecture is correct:

otool -hv libjnipostal.dylib  libpostal.1.dylib

libjnipostal.dylib:
Mach header
      magic  cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64    ARM64        ALL  0x00       DYLIB    18       1808   NOUNDEFS DYLDLINK TWOLEVEL WEAK_DEFINES BINDS_TO_WEAK NO_REEXPORTED_DYLIBS


libpostal.1.dylib:
Mach header
      magic  cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
MH_MAGIC_64   X86_64        ALL  0x00       DYLIB    14       1696   NOUNDEFS DYLDLINK TWOLEVEL NO_REEXPORTED_DYLIBS

hum so the cppbuild.sh must be incorrect: https://github.com/bytedeco/javacpp-presets/pull/1205/files#diff-ae4eed1b337db40a14189f50b893c841de813757ab17c9f41e6d903263ab6f86R45

To get cross compilation working with Autotools (or CMake for that matter), you'll probably need to set CC="clang -arch arm64 -fPIC" and CXX="clang++ -arch arm64 -fPIC" like this:

ok got it, I'm really sorry:

#1207

[saudet]

There's actually no C++ files in libpostal, so we should be able to do the same as libffi. Could you test only with CC="clang -arch arm64?

This has been released with version 1.5.8. Thanks for the contribution!
