Working with UNO on Fedora Linux 64 bits after add references to the SDK libraries libuno_cppu.so, libuno_cppuhelpergcc3.so, libuno_purpenvhelpergcc3.so, libuno_sal.so and libuno_salhelpergcc3.so in the folder /usr/lib64/libreoffice/sdk/lib and add as linking path the folder /usr/lib64/libreoffice/program I get the following error on my IDE (codeblocks 20.03)

What are the libs and paths to link the UNO library right in an application?
I’m doing an application to make reports in calc ods files, I need the objects and methods in the UNO library to create and manipulate these files. At the beginning I don’t understood much the philosophy of the library but after doing an extensive read to the poor quality documentation of UNO I finally make a little progress. After successfully compile a own library that have a method to create an ods file now I’m just making a console application to test it. But it not compile and shows the error I posted…
In my lib header I have
#include <stdio.h>
#include <wchar.h>
#include <sal/main.h>
#include <cppuhelper/bootstrap.hxx>
#include <com/sun/star/lang/XMultiComponentFactory.hpp>

#include <com/sun/star/frame/XComponentLoader.hpp>
#include <com/sun/star/sheet/XSpreadsheet.hpp>
#include <com/sun/star/sheet/XSpreadsheetDocument.hpp>
#include <string.h>
#include "appset.h"
#include "interop.h"

ATTRS int ODSLoad();
ATTRS int ODSCreateFile(const string& full_file_name);
In the source file I have
int ODSLoad()
{
connection_string=OUString("uno:socket,host=localhost,port=2083;urp;StarOffice.ServiceManager;");
resolver_namespace=OUString("com.sun.star.bridge.UnoUrlResolver");

x_component_loader=Desktop::create(x_context);
return 0;
}
int ODSCreateFile(const string& full_file_name)
{
OUString calc_doc_url=StringToOUString(full_file_name);
x_component=Reference<XComponent>(
x_component_loader->loadComponentFromURL(
calc_doc_url,
OUString("_blank"),
0,
Sequence<::com::sun::star::beans::PropertyValue>()
)
);
spread_sheet_doc=Reference<XSpreadsheetDocument>(x_component,UNO_QUERY);
spread_sheet_sheets_set=spread_sheet_doc->getSheets();
Any sheet = spread_sheet_sheets_set->getByName(OUString::createFromAscii("Sheet1"));
spread_sheet_sheet=Reference<XSpreadsheet>(sheet,UNO_QUERY);
}
In the console application I just add the reference to the libs I mention at begginng and the same headers as the lib
