Android question: does cross-compiling require a 32 bit host ECL?
Hi again, In the process of porting EQL5 to Android, I stumbled upon this problem: The app crashes on Android during read_VV(), if the lisp library has been cross-compiled using a 64 bit ECL. To solve this problem, I need to use a 32 bit ECL for cross-compiling: but this would mean that for cross-compiling EQL5 apps we are required to stay with 32 bit ECL for EQL5. Probably not a big deal, but could the Android gurus confirm this? Thanks, Paul
Yes, this is true. The problem is that ECL compiler doesn't have distinction between host architecture and target architecture (it just transpiles code) - so if host implementation has long-double, it will produce C code using long-double, if 64 bit integers are present, then transpiled code is used for that. I'm aware of that problem and I plan to separate compilation and target features. That said, it's probably not something what will be fixed in the upcoming release. Definetely doable though (and useful). On 01.07.2017 20:37, PR wrote:

ok, many thanks (me seems you're a very good ECL maintainer!) 2017-07-01 22:20 GMT+02:00, Daniel Kochmański <daniel@turtleware.eu>:
