copy class cpp and header to folder, its not visible by compiler

JacobNovitsky

I have app linked to shared library
CTE (App) to CTL (Lib)

I want to add new Class to shared Library which can be accessible in app, linked to the .so
When I create new Class with Qt Creator it works and builds and runs fine
If I just copy txt file to folder, its not visible by compiler
What do I miss? Maybe I should affect Makefile or smth else?

TEMPLATE = app
CONFIG += c++17
CONFIG -= app_bundle
CONFIG -= qt

LIBS += -L/home/j/CTL-Debug/debug/debug -lCtl
INCLUDEPATH += /home/j/CTL/

QMAKE_CXXFLAGS_WARN_ON += -Wno-unknown-pragmas -w
QMAKE_CXXFLAGS += -Wno-ignored-qualifiers

QMAKE_CXXFLAGS += -O0 -g

SOURCES +=
main.cpp
LibraryCTL.cpp

HEADERS +=
LibraryCTL.h

main.cpp
#include </home/j/CTL/LibraryCTL.h>

TestFn test;

int main(int argc, char *argv[])
{

return 0;
}

LibraryCTL.h
#pragma once
#ifndef LIBRARYCTE_H
#define LIBRARYCTE_H

using namespace std;
#include <string>

class LibraryCTE
{
public:
LibraryCTE();
~LibraryCTE();
};

#endif

LibraryCTL.cpp
#include </home/j/CTE/LibraryCTL.h>

LibraryCTE::LibraryCTE()
{

}

LibraryCTE::~LibraryCTE()
{

}

TEMPLATE = lib
CONFIG += c++17
CONFIG -= app_bundle
CONFIG -= qt

DESTDIR = debug
TARGET = $$DESTDIR/Ctl

SOURCES +=
TestFn.cpp
LibraryCTL.cpp

HEADERS +=

LibraryCTL.h

#include <LibraryCTL.h>

LibraryCTL::LibraryCTL()
{

}

LibraryCTL::~LibraryCTL()
{

}

#pragma once
#ifndef LIBRARYCTL_H
#define LIBRARYCTL_H
#include <TestFn.h>
using namespace std;
#include <string>

class LibraryCTL
{
public:
LibraryCTL();
~LibraryCTL();
};

#endif

#include <LibraryCTL.h>

TestFn::TestFn(){
}

#ifndef TESTFN_H
#define TESTFN_H
using namespace std;
#include <string>
class TestFn
{

~TestFn();
};

#endif

(I think it might be problem with Qt.pro file and empty/invisible/bad symbols or something like that)
I dont believe it related to Makefile or I can't find any other settings/system files related to building process

So I think problem must be in .pro file

jsulm

@JacobNovitsky said in copy class cpp and header to folder, its not visible by compiler:

If I just copy txt file to folder, its not visible by compiler

What txt file and what folder?
You need to add header/cpp files in the pro file, else the build system knows nothing about these files.
https://doc.qt.io/qt-6/qmake-project-files.html#declaring-other-libraries

And please format your code properly.

problem caused by invisible symbols in cpp file :) thanks for reply
