У меня возникла проблема с компиляцией моего CS hw с помощью make файла. Он будет компилироваться в CodeBlocks, но не с gcc...
→ Файлы находятся здесь... https://github.com/ericmwalsh/cppSortedList
Файлы...
SortedList.h
SortedList.cpp (включает SortedList.h)
PCTimer.h
fileListFunctions.cpp (включает PCTimer.h и SortedList.cpp)
testSortedList.cpp (включает fileListFunctions.cpp)
Теперь я знаю, что я не должен включать файлы cpp друг в друга, но по какой-то причине я не могу использовать свой make файл:
testmake: SortedList.cpp fileListFunctions.cpp testSortedList.cpp
gcc -o testmake SortedList.cpp fileListFunctions.cpp testSortedList.cpp -I.
Ошибка, которую я получаю, выглядит следующим образом:
gcc -o testmake SortedList.cpp fileListFunctions.cpp testSortedList.cpp -I.

make: *** [testmake] Error 1
Сначала необходимо скомпилировать все зависимые файлы (.cpp)
в объекты (.o)
. И свяжите его с конечным объектом (main.o)
чтобы сформировать исполняемый файл.
Посмотрите, как сделать SIMPLE C++ Makefile? ,
Это будет работать,
#Declaration and Definition of Macros which are used in make
CPP = g++
OBJ = SortedList.o fileListFunctions.o testSortedList.o
INCS = -I"include" -I"include" -I"."
BIN=testmake
CXXFLAGS=$(INCS) -O3 -Wall
RM = rm -f
.PHONY: all all-before all-after clean clean-custom
all: all-before $(BIN) all-after
clean: clean-custom
${RM} $(OBJ) $(BIN)
$(BIN): $(OBJ)
$(CPP) $(OBJ) -o $(BIN) $(LIBS)
SortedList.o: SortedList.cpp
$(CPP) -c SortedList.cpp -o $@ $(CXXFLAGS)
fileListFunctions.o: fileListFunctions.cpp
$(CPP) -c fileListFunctions.cpp -o $@ $(CXXFLAGS)
testSortedList.o: testSortedList.cpp
$(CPP) -c testSortedList.cpp -o $@ $(CXXFLAGS)
std=c++11
. Затем вам нужно добавить префикс std lib кstd::
.
