CDTプラグインでEclipseJunoを使用していますが、Indigoでも試しましたが、この問題はそこでも発生します。私はUbuntu12.04を使用しています。
次のコードを使用して新しいC++プロジェクトを作成しました。2行目にブレークポイントを設定しました。
#include <iostream>
using namespace std;
int main() {
cout << "Hello world" << endl;
cout << "Hi there" << endl; // I've set a breakpoint here using eclipse
}
そして私のMakefileはこれです
CXX := g++
CXXFLAGS := -g -c
LDFLAGS := -g -std=c++11
OBJ_FILES := main.o
.PHONY: all clean
all: $(OBJ_FILES)
$(CXX) $(LDFLAGS) $(OBJ_FILES) -o proj2
main.o: main.cpp
$(CXX) $(CXXFLAGS) main.cpp -o main.o
clean:
rm -rf *.o proj2
これをEclipseのデバッグモードで実行すると、すべてが正常にビルドされますが、実行すると、gdbは次のメッセージを出力します。
Error in re-setting breakpoint 1: Function "/home/gulshan/Code/EECS281Workspace/Project 2/main.cpp:7" not defined.
この場合、eclipseが起動時に中断するオプションをオフにしたことは注目に値するかもしれませんが、そのオプションがチェックされている場合、問題なく最初の行で中断できます。
どうしたの？これが役立つ場合のGDBトレースです。
