    <p>I have the following trivial Lua program which I copied from the book Programming In Lua</p> <pre><code>#include &lt;stdio.h&gt; #include &lt;lua.h&gt; #include &lt;lauxlib.h&gt; #include &lt;lualib.h&gt; int main (void) { char buff[256]; int error; lua_State *L = luaL_newstate(); /* opens Lua */ luaL_openlibs(L); /* opens the standard libraries */ while (fgets(buff, sizeof(buff), stdin) != NULL) { error = luaL_loadbuffer(L, buff, strlen(buff), "line") || lua_pcall(L, 0, 0, 0); if (error) { fprintf(stderr, "%s", lua_tostring(L, -1)); lua_pop(L, 1); /* pop error message from the stack */ } } lua_close(L); return 0; } </code></pre> <p>my environment is cywin</p> <p>my make file looks like this:</p> <pre><code>CC=gcc INCLUDE='-I/home/xyz/c_drive/Program Files/Lua/5.1/include' LINKFLAGS='-L/home/xyz/c_drive/Program Files/Lua/5.1/lib' -llua51 li.o:li.c $(CC) $(INCLUDE) -c li.c main:li.o $(CC) -o main $(LINKFLAGS) li.o clean: rm *.o rm main </code></pre> <p>My /home/xyz/c_drive/Program Files/Lua/5.1/lib directory contains lua5.1.dll lua5.1.lib lua51.dll and lua51.lib</p> <p>Trying to build my main target I am getting the following errors:</p> <pre><code>li.o:li.c:(.text+0x35): undefined reference to `_luaL_newstate' li.o:li.c:(.text+0x49): undefined reference to `_luaL_openlibs' li.o:li.c:(.text+0xaf): undefined reference to `_luaL_loadbuffer' li.o:li.c:(.text+0xd9): undefined reference to `_lua_pcall' li.o:li.c:(.text+0x120): undefined reference to `_lua_tolstring' li.o:li.c:(.text+0x154): undefined reference to `_lua_settop' li.o:li.c:(.text+0x167): undefined reference to `_lua_close' </code></pre> <p>Any ideas about what I might be doing wrong here?</p>

    1. COHow did you build the lua51.lib? If the lib was compiled with C++ compiler then your program should also be compiled (and linked) with C++ compiler.

    2. COI downloaded the bin version from lua's web site... The compiler I use is gcc (not g++)..... I will try to download the source code and compile it

    3. COThere are several different binary versions there, built with different compilers. What specific package did you get?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
