So building liblua.a was pretty straightforward as a "Ken" has already done
the heavy lifting in the makefile. I can call gmake as:
gmake ARCH=sparc-rtems5 BSP=erc32 BSP_BASE=~/development/rtems/5
and "make install" puts liblua.a in the correct directory. But I am getting
a linking errors with my example code that seem to imply a missing math
library? I copied the RTEMS hello example and added the Lua C example from
the Programming in Lua book (4th edition for 5.3). The files and build
output follow.
//test-lua.c
#include <bsp.h>
#include <lua.h>
#include <lualib.h>
#include <lauxlib.h>
//This is the reference to the lua interpreter
lua_State* L;
rtems_task Init(
rtems_task_argument ignored
)
{
lua_State *L = luaL_newstate();
luaL_openlibs(L);
char buff[256] = "print('Hello from Lua')";
//Test of basic lua functionality
int error;
error = luaL_loadstring(L, buff);
if(error)
{
fprintf(stderr, "%s\n", lua_tostring(L,-1));
lua_pop(L,1);
}
lua_close(L);
return 0;
}
