Atualmente estou trabalhando com o Ubuntu 16.04.3 LTS. Você deve saber que sou completamente conhecido em qualquer ambiente Linux, então, por favor, desculpe minha falta de detalhes, se houver algum.
Eu tenho que trabalhar com a biblioteca ROOT for C ++, desenvolvida pelo CERN. A instalação com sudo make install falhou e eu tive que instalá-lo através de cmake .
Quando eu lanço um terminal e digito root , parece funcionar, exibindo todas as informações corretamente.
No entanto, ao usar o seguinte makefile (incluído no final do post), recebo um relatório de erro realmente estendido, que começa com:
g++ -Wall -c -o Precision_DiffFinie.o -I'~/root-6.12.04/builddir/bin/root-config --incdir' Precision_DiffFinie.cpp

Acho que os seguintes erros se devem ao fato de o compilador C ++ não entender o que eu escrevi, já que ele não poderia linkar para a biblioteca ROOT.
Alguém sabe como consertar isso, ou pode me explicar o que estou fazendo de errado? Eu tentei fazer tudo de bom, mas certamente perdi alguma coisa; e eu tenho tentado consertar isso por muito tempo para entender qualquer coisa por conta própria agora.
O makefile :
# Makefile pour les exercices de calculs numeriques
# definition du compilateur
GPP=g++ -Wall
# lien vers les fichiers d'en-tete des classes ROOT (ROOTINC) et les librairies (ROOTLIB), cad les fichiers binaires
ROOTINC=-I'root-config --incdir'
ROOTLIB='root-config --libs'
#La liste des executables a compiler
# les executables sont en .exe pour pouvoir beneficier de la regle generique de conversion de .o en .exe
EXE=MinMaxTableau.exe Optimisation_CalculSerie.exe Precision_DiffFinie.exe MethodeSecante.exe

Muito obrigado.
