   LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in
  hi,LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartupi am facing the errors but i want to link statically . so i don't want to ignore libc libraries and i have tried with all the subsystems(console and windows) but nothing works . There is no minimum use of ATL also. There is a _DllMainCRTStartup function which is set as the entry and one more thing to note is the file is a .c file . i am quoting this because when i rename the file to .cpp and remove the entry point .its builds without linker errors. But unfortunately i am not allowed to do this.The configuration is Win32/Release.Hope these information is enough. Can any one help at the earliest   
  ___tmainCRTStartup is a EXE file entry point._DllMainCRTStartup is a DLL file entry point.Are you building a DLL or EXE?   ;  i am trying to buid a DLL;  When you created the project, did you explicitly create a DLL, or did you just create a Win32 application project?And what IDE are you using?   ;  S i expl defined as dll . i am buiding in visual studio 2005.actually while creating i created as win32 application and in that i have selected dll option.;  Can you create a minimal project that shows this behaviour? I just created a new DLL project with a .c file with the following contents, and the entry point set in the linker settings, and it links fine:void __stdcall _DllMainCRTStartup(void* hinstDLL, unsigned long fdwReason, void* lpReserved){};  IT WORKS BUT try including this  code segment with that _DllMainCRTStartupint test(){int *i;i= (int*) malloc(4);return 0;}it now fails with the same error..now can you get some idea ..   ;Quote:Original post by gshankaranIT WORKS BUT try including this  code segment with that _DllMainCRTStartupint test(){int *i;i= (int*) malloc(4);return 0;}it now fails with the same error..now can you get some idea ..Of course it will fail. You cannot call a CRT function (malloc) in the function that is supposed to initialize the CRT...Why are you overloading _DllMainCRTStartup anyway ? You do realize that there is a whole ton of stuff you have to manually include in that function for it to work properly (init the CRT, call static ctors, etc) ? Just use DllMain instead.;  is there any other way to make it run with the use of _DllMainCRTStartup..if so can you please help me..what are the changes i should do.   ;Quote:Original post by gshankaranis there any other way to make it run with the use of _DllMainCRTStartup..if so can you please help me..what are the changes i should do.As I said above, use DllMain. There are very few reasons to use _DllMainCRTStartup instead (eg. if you wrote your own replacement CRT, or if you are targeting a system without CRT), and none of these apply to you.
