All the time I wondered about the dependencies and size of bit.dll.
Encouraged by my work on a gpx decompression lib I twiddled
around with LuaBitOp-1.0.1 and did the following patch
bit.c
180,192d177
+ #ifdef _WIN32
+ #pragma comment(linker, "/OPT:NOWIN98")
+
+ #include <windows.h>
+ BOOL WINAPI DllMain(
+ HINSTANCE hinstDLL,
+ DWORD fdwReason,
+ LPVOID lpvReserved
+ )
+ {
+ return TRUE;
+ }
+ #endif
msvcbuild.bat
21c20
- %MYLINK% /DLL /export:luaopen_bit /out:bit.dll bit.obj %LUA_LIB%
+ %MYLINK% /DLL /entry:"DllMain" /export:luaopen_bit /out:bit.dll
bit.obj %LUA_LIB%
And WOW, this reduced bit.dll from 20480 to 4096 bytes and completly
removed the dependency from any msvcrt*.dll. I did not see any bad
side effects yet, the msvctest.bat runs flawlessly.
Do you have any cons for this approach?
