You can't use your host OSs headers with OSXCross. You can install openssl with osxcross-macports:
export MACOSX_DEPLOYMENT_TARGET=10.15 # or whatever version you want
osxcross-macports install openssl
export OSXCROSS_MP_INC=1
Have a look at https://github.com/tpoechtrager/osxcross/blob/master/README.MACPORTS.md
Thanks for the quick reply and indeed compilation now works.
This project is awesome...and to me black magic :-)
Goal: cross-compile a Rust programm for OSX on Linux
My application has a dependency on openssl which requires openssl header files to be present on the Linux system. So on my Suse box I have to run
zypper install openssl-devel
to be able to compile. Cross-compiling to Windows also works with the GNU toolchain. After setting up osxcross with XCode 13, compilation works but when linking kicks in the rust-linker is not able to "see" the openssl headers anymore. Since it works for the other two I can only assume that osxcross toolchain (x86_64-apple-darwin20.4-clang) does not have access to the header files on my Linux system (it may technically not even possible). I also read that OSX in general seems to be moving away from openssl. So I tried with XCode 11 SDK but got the same result.Is this a known limitation of osxcross? Can you include openssl in the toolchain so the linker is satisfied (and it works).
Coming from Java, this cross-compiling is quite new to me, so please bear with me :-)
