Is there a flag to set another architecture type during the compilation process?
For example I’m on an Intel Mac but I want to make a project build for ARM Mac (or a fat binary) to not use Rosetta 2 for that version.
Or, I’m on a Mac but want to cross compile the lisp project/static library to windows.
Trying to integrate some code into a CI platform. Thx!

Dear Joshua,
it is possible to cross-compile lisp code using ECL. Basically, one needs to set up paths the compiler and linker binaries as well as paths to the include and library directories in the host compiler (built in the first step of cross-compiling ECL itself, see the INSTALL file for instructions) to point to the ones for the target system.
One can then call `compile-file` as usual, taking care to either load files with the bytecompiler or compiling twice (once for the target and once for the host) before loading.
For an example how this works, see the EQL5 project https://gitlab.com/eql/EQL5-Android/. You could also look at https://gitlab.com/spaghettisalat/jffi_repl_example/blob/master/app/src/main... for an example with a basic asdf integration.
Best regards, Marius Gerbershagen

Thanks, Marius.
So for Intel to M1, we’d need the binaries for M1 and use the byte compiler?

I'm not sure that I'm understanding your question correctly, so let me summarize the steps needed to cross-compile a lisp library in more details:
1. Cross-compile ECL itself. You can do this by essentially the same steps as for iOS/Android detailed in the INSTALL file: first build a "host ECL" (in your case a version of ECL that runs on Intel Macs), then run configure with `--host` and `--with-cross-config` options and make (this will use the host ECL to compile a target ECL, i.e. a version of ECL which will run on the M1).
2. Start the host ECL built in step 1, set up the compiler paths and flags as shown in the examples that I linked in my previous email.
3. Call compile-file, c:build-static-library or c:build-shared-library etc. as usual. This will produce a binary for the target system (in your case a M1 Mac) which is linked against the target ECL. Due to that, you can't directly load the fasl's that this compilation procedure produces into the host ECL. Thus if you have dependencies between files which necessitate loading files (for instance if you define a macro in one file and use it in another), the easiest option is to use the bytecompiler to load files. If this fails, you may compile fasls using the default configuration of the host ECL (that is restore all paths and flags set in step 2 to their default values) and then load that.
I hope this explains how everything works.
Best, Marius
