Description
Can you give some advice how to compile libvim to WebAssembly? its mentioned in the README.md but I could not find any instructions how this is done.
I do not know the esy tool very well, but I think I was able to build the library under linux using this script in src/build (running it from src):
# build in this folder cur__install=my_build_wasm # the lib folder is not created by the makefile for some reason -> created it manually mkdir -p $cur__install/lib emconfigure ./configure --disable-selinux CFLAGS=-fPIC emmake make installlibvim DESTDIR=$cur__install
There were some failing checks though (not sure if this is the problem):
checking --with-tlib argument... empty: automatic terminal library selection checking for tgetent in -ltinfo... no checking for tgetent in -lncurses... no checking for tgetent in -ltermlib... no checking for tgetent in -ltermcap... no checking for tgetent in -lcurses... no no terminal library found checking for tgetent()... configure: error: NOT FOUND! You need to install a terminal library; for example ncurses. Or specify the name of the library with --with-tlib.
Anyway I got a libvim.a file and tried compiling this code:
#include <stdio.h>
#include "libvim.h"
void sayHello() {
printf("hello\n");
}
int main(int argc, char** argv) {
vimInit(argc, argv);
sayHello();
}
using this command:
emcc -Iinclude -Iinclude/proto -DHAVE_CONFIG_H -fPIC main.c lib/libvim.a -o index.html
But then I got this error:
wasm-ld: error: unknown file type: libvim.o
This works fine using gcc:
# after running the same build script but with configure/make instead of emconfigure/emmake
gcc -Iinclude -Iinclude/proto -DHAVE_CONFIG_H main.c lib/libvim.a -lSM -lICE -lXt -lX11 -lXdmcp -lm -ltinfo -lnsl -ldlAny idea what could be wrong? Did you have success using this library with WebAssembly yet? If so it would be great if you could add some directions how.
