私はシンプルなシングルスレッドメッセンジャーサービスのためにサーバ/クライアントを動かすことに取り組んできました。 Visual Studioでコンパイルすることはできますが、メイクファイルを使用してLinux上でコンパイルしようとすると、コマンド：make clientを使用すると、非常に大きなエラーリストが表示されます。私は冒頭部分、その後、エラーのリストを提供します：G ++を使用して、未定義のリファレンスstd :: Makefile
をここでは、少なくとも++グラムを使用しようとしていることを述べている：言わエラーの
g++ -g -c -o client.o client.cc cc client.o -o client client.o: In function
main': /home/peter/Desktop/CS360/Messaging_Service/messenger/client.cc:10: undefined reference tostd::allocator::allocator()'EDIT: I noticed something unusual here. When I call
make clientagain without callingmake cleanI get the following:[email protected]:~/Desktop/CS360/Messaging_Service/messenger$ make client cc client.o -o client client.o: In function
main': /home/peter/Desktop/CS360/Messaging_Service/messenger/client.cc:10: undefined reference tostd::allocator::allocator()' Not sure if this is significant or not, but it doesn't mention g++ again.

この私のメイクファイルに誤りがあると私に信じさせる。私はg ++を使用していますが、コンパイルもうまくコンパイルされていると思いますので、ここからどこに行くのかについてはあまりよく分かりません。私のMakefileは次のとおりです。
CXX= g++ $(CCFLAGS)
MSG-SERVER= server.o
MSG-CLIENT= client.o
OBJS = $(MSG-SERVER) $(MSG-CLIENT)
LIBS =
CCFLAGS = -g
all: msg-server msg-client
msg-server:$(MSG-SERVER)
$(CXX) -o server $(MSG-SERVER) $(LIBS)
msg-client:$(MSG-CLIENT)
$(CXX) -o client $(MSG-CLIENT) $(LIBS)
clean:
rm -f $(OBJS) $(OBJS:.o=.d)
realclean:
rm -f $(OBJS) $(OBJS:.o=.d) server client
# These lines ensure that dependencies are handled automatically.
%.d: %.cc
$(SHELL) -ec '$(CC) -M $(CPPFLAGS) $< \
| sed '\''s/\($*\)\.o[ :]*/\1.o [email protected] : /g'\'' > [email protected]; \

あなたのメイクファイル実行の完全なトレースを表示できますか？私はいくつかのCコンパイルが関係していると思っています... –
元の投稿に入れました。それが完全なトレースの意味だったら、メイクファイル実行のファイルパスに入力しました。 – Petorix
つまり、トレース'make'実行の中で、質問にしてください。 –
