Cannot open NeoMathEngine.x64.Debug.lib

[goodle06]

NeoML showing linker error. In Qt it looks like this:

:-1: error: LNK1104: cannot open file 'NeoMathEngine.x64.Debug.lib'

And in built libraries there is nowhere to be found NeoMathEngine.x64.Debug.lib.
When I'm trying with Visual studio, I'm getting following output:

Severity	Code	Description	Project	File	Line	Suppression State
Error	C3861	'NOT_FOUND': identifier not found	NeoMLTest2	K:\NeoML\build64\debug\include\NeoML\TraditionalML\LdGraph.h	438	

Code snippet where error is located seems to be some kind of assertion, but I can't understand what's wrong:

inline void CLdGraph<Arc>::DetachArc( Arc* arc )
{
	// Delete the arcs from the starting node
	CLdGraphVertex* initial = vertices[arc->InitialCoord() - begin];
	NeoPresume( initial != 0 );
	int i = initial->OutgoingArcs.Find(arc);
	NeoAssert( i != NOT_FOUND ); //     PROBLEM IS HERE
	initial->OutgoingArcs.DeleteAt(i);
	// Delete the hanging node
	if( initial->OutgoingArcs.Size() == 0
		&&  initial->IncomingArcs.Size() == 0 )
	{
		delete initial;
		vertices[arc->InitialCoord() - begin] = 0;
	}

I have 4 of those errors.

Thanks for the report! It's a bug (NOT_FOUND must be replaced with NotFound). I will push fix soon.

@FedyuninV great, thanks!

[goodle06]

@FedyuninV I replaced NOT_FOUND with NotFound, and now Visual Studio asks for 'NeoMathEngine.x64.Debug.lib':

Severity	Code	Description	Project	File	Line	Suppression State
Error	LNK1104	cannot open file 'NeoMathEngine.x64.Debug.lib'	NeoMLTest	C:\Users\JackOfShadows\source\repos\NeoMLTest\NeoMLTest\LINK	1	

Any idea why is this happening? Mistakes related to NOT_FOUND are gone.

[FedyuninV]

Can you put, please, your generate and build commands? What is inside your NeoMLTest project?

[goodle06]

@FedyuninV , I'm building via command line with this input:

cmake -G "Visual Studio 16 2019" -A x64 K:\NeoML\NeoML2\src\NeoML -DCMAKE_INSTALL_PREFIX=K:\NeoML\NeoML2\target\release -DCMAKE_PREFIX_PATH=C:\Users\Me\vcpkg\installed\x64-windows

cmake --build . --target install --config Release

Inside NeoMLTest project I"ve just added headers and tried to compile:

#include <iostream>
#include <NeoMathEngine/NeoMathEngine.h>
#include <NeoOnnx/NeoOnnx.h>
#include <NeoML/NeoML.h>


int main()
{
    std::cout << "Hello World!\n";
}

I faced same problem: LNK1104 cannot open file 'NeoMathEngine.x64.Release.lib, when try to compile next one (https://github.com/neoml-lib/neoml/blob/master/NeoML/docs/en/Tutorial/SimpleNet.md)
it's not working with x86/x64 Release/Debug, always same problem.
I tried to make another one project and faced this again...

#include <iostream>
#include "windows.h"
#include "NeoML/NeoMLCommon.h"
#include "NeoML/FineObjLite/FineObjLite.h"
#include "NeoML/Random.h"
#include "NeoML/NeoML.h"

int main()
{
    std::cout << "Hello World!\n";
}

Here is my project properties:

Linker -> input -> Additional Dependecies: 	NeoMathEngine.lib;NeoML.lib;
Linker -> General -> Additional Library Directories: D:\trash\neoml\Install\NeoMathEngine\src\Release;D:\trash\neoml\Install\src\Release;
C/C++ -> General -> Additional Include Directories: D:\trash\neoml\NeoMathEngine\include;D:\trash\neoml\NeoML\include;

I can't reproduce it locally, but I have an idea.

Can you please do the following:

1. update to the latest master
2. replace this line with #if defined( FINEOBJ_VERSION ) && !defined( CMAKE_INTDIR )

@FedyuninV @Columbiysky , hello! I followed your instructions and it seems to be built successfully with following output with Release mode project:

1>------ Rebuild All started: Project: NeoMLTest, Configuration: Release x64 ------
1>NeoMLTest.cpp
1>Generating code
1>Previous IPDB not found, fall back to full compilation.
1>All 25 functions were compiled because no usable IPDB/IOBJ from previous compilation was found.
1>Finished generating code
1>NeoMLTest.vcxproj -> C:\Users\JackOfShadows\source\repos\NeoMLTest\x64\Release\NeoMLTest.exe
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========

In Debug mode it builds without any warnings:

1>------ Rebuild All started: Project: NeoMLTest, Configuration: Debug x64 ------
1>NeoMLTest.cpp
1>NeoMLTest.vcxproj -> C:\Users\JackOfShadows\source\repos\NeoMLTest\x64\Debug\NeoMLTest.exe
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========

I'll try to test it and return with results.

Please, see to correct include path to FineObjLite.h in NeoMLDefs.h. It is built with #include <FineObjLite.h> and doesn't compile until you change it to full path like this: #include <NeoML/FineObjLite/FineObjLite.h>
