LNK1120 on compile

[ghost]

Hi I trying to use RLib in vs2015 , The Rlib compile successfully but when wanna to use it(.lib) in a project i always got LNK1120 and LNK2019 Errors , It says can't resolve external symbols, Even for the following sample!

#include "RLib_Import.h"

int main()
{
    String rlibString;

    return 0;
}

Error	LNK1120	2 unresolved externals	Project1	C:\Users\ccc\Downloads\Compressed\RLib-master\Debug\Project1.exe	1

Hi, m0ax4vin, you can just include RLib_LibImport.h instead of RLib_Import.h, or add RLIB_LIB to preprocessor definitions.

I do that too but the same result:

#include "RLib_LibImport.h"

using namespace System::Ini;

int main()
{
    IniFile ini;
    ini.Items.Add(new IniComment()); // empty comment
    ini.Items.Add(new IniComment(_R(" This File has been generated by RLib")));
    ini.Items.Add(new IniComment(_R(" Copyright (c) 2016 rrrfff, [email protected]")));

    ini["Section"]["Key"] = _R("Value");
    ini.SaveFile(_T("Config.ini"), UTF8Encoding);

    return 0;
}

it seems that library directories was not properly set up

[ghost]

No i set the directory now compile this simple code but any interact with String or other classes will cause same problem :|

#include "RLib_LibImport.h"
int main()
{
    String rlibString = "hello";
   
    return 0;
}

Please if it's possible give me an example project with .sln project file, may i set up something in wrong way. Thanks.

[Rprop]

you can use this wizard tool to help you create project, https://github.com/rrrfff/RLib/tree/master/Wizard, and its source code can be found here https://github.com/rrrfff/RLib/tree/master/Templates/Wizard

example projects are provided at https://github.com/rrrfff/RLib/tree/master/Examples, you can use those .vcxproj directly

[ghost]

Thanks a lot.

Create a project .. but now it looking for ntdllp_x86.lib file, where is it ? ntdll_x64.lib and ntdll_x86.lib are in RLib-master\RLib\native\native.zip i extracted theme but don't found ntdllp_x86.lib

Severity Code Description Project File Line Error LNK1104 cannot open file 'ntdllp_x86.lib' test C:\Users\cccc\Downloads\Compressed\RLib-master\Wizard\test\LINK 1

[Rprop]

sorry, i will upload them soon

now you can find them here https://github.com/rrrfff/RLib/tree/master/RLib/native

[ghost]

Thanks again i got new files

I compile Rlib in all possible forms (dll, lib, debug,release ....) in Bin folder. Then Create a project put compiled files on $(OutDir); of created template project Then try to compile default code:

#include <RLib_Import.h>
#include <RLib_NoCRT.h>
void main()
{
	String example = _R("RLib Example");`
}

In this case i got error Error LNK1104 cannot open file 'RLib_x86d.lib' Because "RLIB_LIB " isn't defined (It define when include "RLib_LibImport.h") and try to link RLib_x86d.lib instead of RLib_x86dl.lib

#  ifdef RLIB_LIB
	RLIB_IMPORT_LIB("RLib_" RLIB_PLATFORM "dl")
#  else
	RLIB_IMPORT_LIB("RLib_" RLIB_PLATFORM "d")
#  endif // RLIB_LIB

When include "RLib_LibImport.h" got this errors

simply delete or comment out #include <RLib_NoCRT.h> will solve your problem, because RLib_NoCRT.h doesn't work if you use static libarary, it will disable the use of CRT

[ghost]

Ohhh :-),it's fine.

A little mention, If use main() function got an error

int _tmain()
{
	String example = _R("RLib Example");
    return 0;
}

Severity	Code	Description	Project	File	Line
Error	LNK2019	unresolved external symbol _WinMain@16 referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ)

Replace main() by WinMain(...) Everything was ok

int __stdcall WinMain(__in HINSTANCE /*hInstance*/, __in_opt HINSTANCE /*hPrevInstance*/,
    __in LPSTR /*lpCmdLine*/, __in int /*nShowCmd*/)
{
	String example = _R("RLib Example");
    return 0;
}

Thanks for your great lib and great support. Greetings.

[Rprop]

Thanks, got it.

And the cause is that the project has Windows (/SUBSYSTEM:WINDOWS) specified rather than Console (/SUBSYSTEM:CONSOLE)
