Questo è fonte di confusione. Io ho la mia Makefile:GNU Produce un risultato completamente diverso
OBJECTS =
INCLUDE_BUILD_PATH = /Users/wen/Projects/include
# Change compilation settings here
COMPILE = g++
override COMPILE_FLAGS += -O2
# Change linker/compiler specific settings here
LD_FLAGS :=
CC_FLAGS := -c -I$(INCLUDE_BUILD_PATH)/bigint
# Add source extensions here
SRC_EXT = cpp cc
# Add header dependencies here
HEADERS = $(wildcard *.hpp) $(wildcard $(INCLUDE_BUILD_PATH)/*/*.hh)
# Add source files here
CC_FILES = $(wildcard *.cpp) $(wildcard $(INCLUDE_BUILD_PATH)/*/*.cc)
CC_O_BUFFER = $(CC_FILES)
CC_O_BUFFER := $(CC_O_BUFFER:.cpp=.o)
CC_O_BUFFER := $(CC_O_BUFFER:.cc=.o)
OBJECTS = $(CC_O_BUFFER)
# Change .exe name here
EXE_NAME = maketest
# Link object files
$(EXE_NAME): $(OBJECTS)
$(COMPILE) $(COMPILE_FLAGS) $(LD_FLAGS) -o [email protected] $^
# Build source files
define compile_rule
%.o : %.$1
$$(COMPILE) $$(COMPILE_FLAGS) $$(CC_FLAGS) -o [email protected] $$<
endef
$(foreach EXT,$(SRC_EXT),$(eval $(call compile_rule,$(EXT))))
# Clean
clean:
rm -f $(OBJECTS) $(EXE_NAME)
# Debug Build
debug:
@echo "Rerun with COMPILE_FLAGS=-D_DEBUG"
# Print variables
print:
@echo $(CC_FILES)
@echo $(OBJECTS)
@echo $(HEADERS)
è compilato con successo in un primo momento, ma poi si è fermato per nessun motivo e questo era l'output:
Yoshi-Air:maketest wen$ make
c++ -c -o maketest.o maketest.cpp
maketest.cpp:4:10: fatal error: 'BigIntegerLibrary.hh' file not found
#include "BigIntegerLibrary.hh"
^
1 error generated.
fosse il problema, non ho nemmeno dirlo a usa "C++" nel Makefile ma "g ++" invece. Inoltre, quando ho cancellato CC_FLAGS
il -c
era ancora lì. È come se Make avesse una mente propria.
Se uso make print
stampare le mie variabili sembra essere tutto a posto:
maketest.cpp /Users/wen/Projects/include/bigint/BigInteger.cc /Users/wen/Projects/include/bigint/BigIntegerAlgorithms.cc /Users/wen/Projects/include/bigint/BigIntegerUtils.cc /Users/wen/Projects/include/bigint/BigUnsigned.cc /Users/wen/Projects/include/bigint/BigUnsignedInABase.cc

Qualsiasi aiuto o consiglio sarà apprezzato. Grazie!
Aggiornamento
ho aggiornato il mio print
per stampare l'esecuzione atteso di compilazione:
print:
@echo $(CC_FILES)
@echo $(OBJECTS)
@echo $(HEADERS)
@echo "Compiles with:"
@echo $(COMPILE) $(COMPILE_FLAGS) $(LD_FLAGS) $(CC_FLAGS)
Risultato:

Compiles with:
g++ -O2 -c -I/Users/wen/Projects/include/bigint
Ciò dimostra che marca sa quello che volevo, ma quando si costruisce è completamente diverso: c++
anziché g++
?!
Aggiornamento 2:
c++
invoca clang, installato sul mio sistema.
Soluzione da Alex B:
Ma dalla riga di comando di compilazione sembra Marchio sta cercando di usare la regola suffissi implicita, e ignora la regola modello.
Ho provato .SUFFIXES:
e sì, ha rilevato una regola non trovata. Grazie, andrò a consultare il manuale.
Il mio consiglio? Controlla se esiste "" BigIntegerLibrary.hh "". –
Questo mi è stato detto molte volte; esiste. Il problema è che make non ha incluso CC_FLAGS correttamente per passare il percorso di inclusione al compilatore. –
Oh. E così, vediamo ... –
