I'm having some problems with the llvm-box. I noticed that the llvm-box did not have any console output at runtime, and the exit code was always 1. So I modified the llvm-box wrapper like this :
int main(int argc, const char ** argv) {
printf("hello,world"); // add this
if (argc < 1) return 2; // change this
const char * argv0 = argv[0];
--argc;
++argv;
#include "llvm-box-entry-gen.hpp"
fprintf(stderr, "LLVM command \"%s\" not found", argv0);
return 1;
}
It can be sure that argv is set, but the exit code is still 1 and printf("hello,word") doesn't output anything. Testing with my own wasm hello world program outputs it correctly.
I'm not an expert on wasm, am I doing something wrong? Thank you.
Hmm, it seems that printf is used differently in llvm-box compared to a simple printf version of wasm. The TTY part of the JS code was not called throughout the process.
Hi, thanks for the very cool work you do!
