Hi Ariel,
Thanks for the reply. I am working on a Linux machine. I use the 1.58
branch.
I am still having trouble of building zlib with the command you provide,
the error message is as follows:
/home/zewang/.emscripten_cache/ports-builds/zlib/compress.c:9:10: fatal
error: 'zlib.h' file not found
#include "zlib.h"
^
1 error generated.
/home/zewang/.emscripten_cache/ports-builds/zlib/adler32.c:8:10: fatal
error: 'zutil.h' file not found
#include "zutil.h"
^
ERROR root: compiler frontend failed to generate LLVM bitcode, halting
1 error generated.
I think there is something wrong with the emscripten repo of zlib cause I
just updated my emscripten.
