Problems With My .pro File and External Libraries (With Example Guideline Makefile)

Question

I'm trying to create a quick GUI which will act as a frontend for some software written by someone else. The problem I'm having seems to be a library issue but I'm going around in circles with the error. Any suggestions on what the error means or what I can try would be greatly appreciated.

File Structure

~/Ph2_DAQ

Inside this I have the many folders but the ones I refer to are:

lib/ src/ TestStand/

The Problem

This is the .pro file I've made in /TestStand which needs to be compiled in C++11:

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = TestStand
TEMPLATE = app

QMAKE_CXXFLAGS += -pedantic -std=c++11 `root-config --cflags --evelibs` #Added these flags

INCLUDEPATH += /opt/cactus/include ../ 

#LIBS += -L/opt/xdaq/lib
#LIBS += -lcactus_extern_pugixml -lcactus_uhal_log -lcactus_uhal_grammars -lcactus_uhal_uhal

LibraryDirs = /opt/cactus/lib /opt/xdaq/lib ../lib #/***Added to the generated file from here...
LibraryPaths = $(LibraryDirs:%=-L%)
LIBS += $(LibraryPaths:%=-L%) -uhal -lboost_system -lboost_thread -lpthread -lboost_regex -lcactus_extern_pugixml -lcactus_uhal_log -lcactus_uhal_grammars -lcactus_uhal_uhal `root-config --glibs` -lPh2_Interface -lPh2_Description -lPh2_System -lPh2_Tools #***/ ... To here

SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

To test I can call in a special external library which I know I will need, I add this to my main.cpp :

#include "uhal/uhal.hpp"

I run qmake on this and I get a few warnings and errors once I run make in the directory that all look pretty similar:

/usr/local/Trolltech/Qt-4.8.5/bin/uic mainwindow.ui -o ui_mainwindow.h
g++ -c -pipe -pedantic -std=c++11 `root-config --cflags --evelibs` -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/local/Trolltech/Qt-4.8.5/mkspecs/linux-g++ -I. -I/usr/local/Trolltech/Qt-4.8.5/include/QtCore -I/usr/local/Trolltech/Qt-4.8.5/include/QtGui -I/usr/local/Trolltech/Qt-4.8.5/include -I/opt/cactus/include -I.. -I. -I. -o main.o main.cpp

                 from main.cpp:3:

         typedef char T_must_be_placeholder[ I == is_placeholder<T>::value? 1: -1 ];

It then sends a few erros that it can't find my custom libraries despite them being there:

/opt/rh/devtoolset-2/root/usr/libexec/gcc/x86_64-redhat-linux/4.8.2/ld: cannot find -lPh2_Description #(and the same for -lPh2_System & lPh2_Tools)

and if I do the ls command:

ls ../lib/
libPh2_Description.so libPh2_System.so libPh2_Tools.so

The Guideline

The software has this Makefile which has this structure, so I naturally tried copying parts since the software does compile on my computer:

CC              = gcc
CXX             = g++
CCFlags         = -g -O1 -w -Wall -pedantic -fPIC `root-config --cflags --evelibs`
#DevFlags                    = -D__CBCDAQ_DEV__
DevFlags                   =

IncludeDirs     =  /opt/cactus/include ../

IncludePaths            = $(IncludeDirs:%=-I%)

LibraryDirs = /opt/cactus/lib /opt/xdaq/lib ../lib
LibraryPaths = $(LibraryDirs:%=-L%)

ExternalObjects = $(LibraryPaths) -lpthread -lboost_thread -lboost_filesystem -lboost_regex -lboost_system -lboost_thread -lcactus_extern_pugixml -lcactus_uhal_log -lcactus_uhal_grammars -lcactus_uhal_uhal `root-config --glibs` -lPh2_Interface -lPh2_Description -lPh2_System -lPh2_Tools

%.o: %.cc %.h
    $(CXX) -std=c++11 $(DevFlags) $(CCFlags) $(UserCCFlags) $(CCDefines) $(IncludePaths) -c -o $@ $<

Output From Terminal

What Should Be on Output

This is the output from the software (not the GUI) when it compiles correctly using the above makefile:

g++ -std=c++11 -g -O1 -w -Wall -pedantic -fPIC `root-config --cflags -evelibs` -o calibrationtest calibrationtest.cc -I/opt/cactus/include -I../ -L/opt/cactus/lib -L/opt/xdaq/lib -L../lib -lptost_thread -lboost_filesystem -lboost_regex -lboost_system -lboost_thread -lcactus_extern_pugixml -lcactus_uhal_log -lcactus_uhal_grammars -lcactus_uhal_uhal `root-config --glibs` -lPh2_interfaceDescription -lPh2_system -lPh2_Tools

Answer 1

What is the current current directory of your make? Are you using shadow-build option, which generated a build-directory next to your application directory. When using relative library-paths these can getting wrong. So try to use absolute paths or adapt the

../lib

to a relative path, which matches to the lib directory.

And can you show the output in your console for the ld-step. I am not sure, feels like the library paths are not set correctly. Does it works when you write:

LIBS += -L/opt/xdaq/lib
LIBS += -lcactus_extern_pugixml -lcactus_uhal_log -lcactus_uhal_grammars -lcactus_uhal_uhal

instead?
