File not found error while building the project

[sleebapaul]

Would you mind helping with the following files which are not present in the project but imported in the project?

DebugLog/DebugLogging.h
Serialization/SerializationIncludes.h

[dac1976]

Yes they are in my other project on GitHub (CoreLibrary). It's listed under the build requirements in the readme for IP-Freely. Best regards, Duncan Crutchley

Thanks for the reply. I'm finding a hard time setting up the third-party libraries you've mentioned. I'm on an Ubuntu 18.04 machine with Qt 5.12.2.

I've installed boost, loki and cereal through apt-get and downloaded SingleApplication repo to project folder, added the INCLUDEPATH, added the singleapplication header and source files. I've compiled OpenCV from source and linked the library as well.

I downloaded the CoreLibrary repo and included the path. Do I need to compile the CoreLibrary and SingleApplication? If so how to do that?

I get undefined reference error to core_lib and SingleApplication.

Would you mind helping me with the setup (Pretty new to Qt dev)?

Hi, You need to build CoreLibrary as a static lib (.a) using the CoreLibrary.pro project. Make sure you have the code for IP-Freely pulled from the master (not the last tag) and look in the .pro file you'll see what it expects and where it will be looking for things. If you look at my CoreLibrary repo on GitHub I've recently started adding a Wiki and it gives more details about getting CoreLibrary built. For example there are example Qt mkspec .prf files. You'll need to edit these to have paths to the dependencies based on where they are on your system. The wiki explains where to install these in the Qt folder, close Qt Creator first so it picks up the files on startup. After which these give you is easy access to these dependencies in any future project by doing CONFIG += core_lib for example which will make your project reference the mkspec core_lib.prf and thus find CoreLibrary.a and its headers. Make sure you adapt the .pro and .prf files to the contain paths for your system. CoreLibrary.pro shouldn't need changing but you may need to tweak IpFreely.pro's paths. I'm using Manjaro Linux and so all the dependencies are installed through its package manager and so end up in /usr/lib and /usr/include, hence my .prf files reference these locations and you'll need to change the paths in these to match your locations. Hope this helps. Best regards, Duncan Crutchley

I've setup the .prf files and copied the custom_mkspecs folder to my Qt compiler folder under mkspecs. When I try to compile the CoreLibrary project, I get the following linking error.

../Source/CsvGrid/CsvGridCell.cpp
../Source/CsvGrid/CsvGridCellDouble.cpp::2727::1010::  fatal error fatal error: : 'CsvGrid/CsvGridCellDouble.h' file not found'CsvGrid/CsvGridCell.h' file not found

#include "CsvGrid/CsvGridCell.h"
         ^~~~~~~~~~~~~~~~~~~~~~~
#include "CsvGrid/CsvGridCellDouble.h"
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The .pro file needs any addition?

[dac1976]

Shouldn't do. I use this project file on various PCs (Windows and Linux) without issue by just pulling from the current code in master from the repo. Setting up prfs the first time then just building. Have a look on your disk do those files exist? I'm currently at work so if I have time I'll check things later. Best regards, Duncan Crutchley

A couple of other things to check... Make sure as per the Wiki (Requirements and Building section) for CoreLibrary you disable shadow builds for the CoreLibrary project in Qt (for Release, Debug and Profile builds - go to project settings when in Qt Creator IDE). Make sure you have the correct include path in "core_lib_settings.prf" and it is installed in the correct place in Qt's install location, again as per the CoreLibrary Wiki describes. I've just tried a fresh pull from github and I can just build the project straightaway (but I already have correct prf files installed in my Qt folder already).

Thanks for your update. I did uncheck the shadow build, and copy .prf files to the features/unix folder and the linking issue is over. But I've a new error which might not be related to project. But have you seen this one before?

/usr/include/c++/7.3.0/cstdlib:75: error: 'stdlib.h' file not found
#include_next <stdlib.h>
              ^~~~~~~~~~

[dac1976]

Yes a known issue with Qt on Linux sometimes. Happens to me too. Go to the Qt install mkspecs folder find qconfig.pri open in text editor. Add following lines and save, then reopen Qt Creator. QMAKE_DEFAULT_INCDIRS= QMAKE_CFLAGS_IFLAGS= Clean and rebuild project once you've reopen Qt Creator after making the above change. Best regards, Duncan Crutchley

That seems not working. The same error popped again.

I tried find /usr/include/ -name "stdlib.h" and found the file in the directory. Not sure it is the GCC or build-essentials package issue.

Tried this one too, not helping.

The way to fix it is to edit mkspecs/common/gcc-base.conf

Change QMAKE_CFLAGS_ISYSTEM = -isystem
to QMAKE_CFLAGS_ISYSTEM = -I (capital i)

Added QMAKE_CFLAGS_ISYSTEM = -I to CoreLibrary.pro and new error popped.

    ~~~~~^

Update 2/5/2019

@dac1976

I've built the project with the following tweaks.

1. QMAKE_DEFAULT_INCDIRS = to .pro file
2. Adding #include <thread> to TcpConnection.cpp

On Run I get a static lib in CoreLibrary/QtProject/release/libCoreLibrary.a. I think it worked.

I linked the static file to IPFreely project. Do I need to link any other libraries?
