I ran raco-cross (installed on racket cs 8.0 [does this cause trouble for racket cs < 8.2 or is it fine because host and target are both bc?]) to run exe and dist:
;; install dependencies raco cross --workspace /tmp/todays-snapshot --target i386-win32 --vm bc pkg install ;; create exe raco cross --workspace /tmp/todays-snapshot --target i386-win32 --vm bc exe myapp.rkt ;; create dist raco cross --workspace /tmp/todays-snapshot --target i386-win32 --vm bc dist myapp-i386-win32-bc myapp.exe >> Cross configuration Target: i386-win32 Host: x86_64-linux Version: 8.0 VM: bc Workspace: /tmp/todays-snapshot On windows: 1. I had to add the lib subfolder in the dist to the path (else the exe would not find the dlls in there). 2. Copy the dlls from /tmp/todays-snapshot/i386-win32-bc/lib/ to the lib subfolder. [I also tried `raco exe --embed-dlls` but then the libs from 2. are missing from the executable, do I need to run future raco-cross at version cs 8.2 so that this part works, or could I use bc to make it work?] After that the program ran for a bit allowed me to select a directory and then crashed with an exception, probably this is a bug in my application that is windows specific. I need to check that. I also tried the utah snapshots but they don't have i386 builds and the windows7 vm is 32bit, I might also test with 64bit windows10 vm, I am currently downloading it. https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ (in case other people need the link to the test vms, they are for ie testing but you can test other things with it) Anyways so far the experience has been quite good compared to my tries without raco-cross maybe a year ago. schle...@gmail.com schrieb am Samstag, 15.
