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(
