Ich hoffe ihr könnt mir helfen. Ich habe ein kleines Projekt mit CxxTest auf meinem Hauptentwicklungscomputer geschrieben. Auf dieser Maschine funktioniert alles super, keine Probleme. Ich habe jedoch versucht, dieses Projekt auf meinem brandneuen Laptop einzurichten und kann es einfach nicht zum Laufen bringen! Ich vermute, dass etwas mit meiner MinGW-Installation nicht mit CxxTest zu tun hat, aber es ist wirklich schwer zu wissen - und die Fehler stammen aus CxxTest-Dateien. Dies ist die Ordnerstruktur des Projekts:

lib/
    cxxtest-4.3/
src/
    TestUtils.h
    test.cpp
test/
    MyTestSuite.h
    libstdc++-6.dll

uf der Kommandozeile starte ich:

cd test
..\lib\cxxtest-4.3\bin\cxxtestgen --error-printer -o runner.cpp MyTestSuite.h

Dies erzeugt runner.cpp. Jetzt laufe ich:

g++ -o runner.exe runner.cpp -I "../lib/cxxtest-4.3" -std=c++11

Dies funktioniert normalerweise gut, gibt runner.exe aus und führt meine Komponententests aus. Auf meinem Laptop bekomme ich nur Tausende von Fehlern. Hier sind nur die ersten Beispiele:

Wenn ich g ++ auf einer einfachen Hello World-Datei ausführe, funktioniert es einwandfrei. Weiß jemand, was los ist?
