c++ - 使用 Makefile 运行的程序中出现 Xcode 链接错误

Question

我目前正在尝试 fork 该程序 qme-ng 。如果我使用我的 Makefile，似乎一切都会正常。另一方面，如果我想使用 Xcode，就会发生奇怪的事情。

这是我的 Makefile:

CC=g++
CCFLAGS=-D__STDC_LIMIT_MACROS -D__cplusplus -O3 -march=native
LDFLAGS=-L/usr/local/lib -lboost_program_options -lgmp -lgmpxx
SRCDIR=src
INC=-I./include -I/usr/local/include -I/usr/local/boost/include

all: qme-ng
Exception.o: $(SRCDIR)/Exception.cpp
    $(CC) $(CCFLAGS) $< $(INC) -c
greenSizeHash.o: $(SRCDIR)/greenSizeHash.cpp
    $(CC) $(CCFLAGS) $< $(INC) -c
carquois.o: $(SRCDIR)/carquois.cpp Exception.o
    $(CC) $(CCFLAGS) $< $(INC) -c
iceQuiver.o: $(SRCDIR)/iceQuiver.cpp Exception.o
    $(CC) $(CCFLAGS) $< $(INC) -c
mutexplorator.o: $(SRCDIR)/mutexplorator.cpp quiver.o Exception.o
    $(CC) $(CCFLAGS) $< $(INC) -c
greenexplorator.o: $(SRCDIR)/greenexplorator.cpp greenSizeHash.o iceQuiver.o Exception.o
    $(CC) $(CCFLAGS) $< $(INC) -c
greenfinder.o: $(SRCDIR)/greenfinder.cpp iceQuiver.o Exception.o
    $(CC) $(CCFLAGS) $< $(INC) -c
mutexploratorSeq.o: $(SRCDIR)/mutexploratorSeq.cpp quiver.o Exception.o mutexplorator.o
    $(CC) $(CCFLAGS) $< $(INC) -c
rng.o: $(SRCDIR)/rng.c
    $(CC) $(CCFLAGS) $< $(INC) -c
naututil.o: $(SRCDIR)/naututil.c
    $(CC) $(CCFLAGS) $< $(INC) -c
nauty.o: $(SRCDIR)/nauty.c
    $(CC) $(CCFLAGS) $< $(INC) -c
nautil.o: $(SRCDIR)/nautil.c
    $(CC) $(CCFLAGS) $< $(INC) -c
nausparse.o : $(SRCDIR)/nausparse.c
    $(CC) $(CCFLAGS) $< $(INC) -c
naugraph.o : $(SRCDIR)/naugraph.c
    $(CC) $(CCFLAGS) $< $(INC) -c
nautinv.o : $(SRCDIR)/nautinv.c
    $(CC) $(CCFLAGS) $< $(INC) -c

qme-ng: qme-ng.cpp greenexplorator.o greenfinder.o mutexploratorSeq.o mutexplorator.o greenSizeHash.o iceQuiver.o quiver.o Exception.o nautil.o rng.o nauty.o naututil.o nausparse.o naugraph.o nautinv.o
    $(CC) $(CCFLAGS) $(INC) $^ $(LDFLAGS) -o $@

clean:
    -rm -f *.o qme-ng *.cpp~ src/*.cpp~ include/*.hpp~ src/*.c~ include/*.h~

在 Xcode 上，我的 header 搜索路径为 "$PROJECT_DIR"/include /usr/local/include /usr/local/boost/include >。我的库搜索路径是 /usr/local/lib 和 /usr/local/boost/lib。 libboost_program_options.dylib、libgmp.dylib 和 libgmpxx.dylib 位于我的“链接二进制文件与库”中。正如某些网页所建议的那样，我还将这三个库复制到 $PROJECT_DIR 中。

目前我遇到以下 Apple Mach-O 链接器错误:

已编辑:我重构了程序，将大多数法语单词翻译成英语。因此，这些话已被更改。

查看项目导航器。您应该在几个地方看到文件是否正在编译和链接。

上图显示了项目导航器。构建阶段将显示文件是否正在编译。

您需要检查的下一件事是查看文件检查器。它向您显示文件属于哪个目标。
