Hi all!
I've already built successfully srlua on Windows using the "clean C
distribution" (srlua.tar.gz)
Then I noticed the file srlua.tgz and that it also contains a wsrlua.c
file which avoids displaying a DOS black box when running a
srlua-packaged executable.
I tried to compile it, but it always fails, no matter what I try.
System: Windows XP
Compiler: tdm-gcc 4.3.1
I tried to compile wsrlua.c with the following invocation:
---------------------------
gcc -c -O2 -Wall -pedantic -std=c99 -mwindows -mwin32 -I
G:\root\main\core\Lua/app/Lua-sys/include winsrc/wsrlua.c -o
winbuild/wsrlua.o
winsrc/wsrlua.c: In function 'thMain':
winsrc/wsrlua.c:13:16: error: '__argc' undeclared (first use in this
function)
winsrc/wsrlua.c:13:16: note: each undeclared identifier is reported only
once for each function it appears in
winsrc/wsrlua.c:13:24: error: '__argv' undeclared (first use in this
function)
mingw32-make: *** [build] Error 1
---------------------------
it always complains about those two missing identifiers: __argc and __argv.
I see that in the distribution there are some MS-compilers project
files, so I fear wsrlua.c is compilable only with MS toolchain.
Is there a way to compile it with my compiler?
Any help appreciated.
Cheers.

I solved the issue modifying wsrlua.c (but I still don't know if it is a
reliable solution or it has some unwanted side effects).
I added these two declarations just after the #include directives at the
top:
--------------------
extern int __argc;
extern char** __argv;
---------------------
TDM-MINGW 4.5.1 still complained (with an info message) about implicitly
using auto imports without the proper command line switch, but this
message went away when I updated to TDM-MINGW 4.5.2.
(Sorry for the typo in the previous message, in which I indicated 4.3.1
as the compiler version - it was meant to be 4.5.1).
If what I found is a sound solution for compiling wsrlua.c with mingw,
wouldn't it a good thing if this modification were added to the original
source?
Thanks.
