I made this MakeFile for a project in C lang:
CC = g++
CFLAGS = -c -std=c99 -g
LDFLAGS = -g
SRC = ${wildcard src/*.c}
HDR = ${wildcard include/*.h}
OBJ = ${SRC:.c=.o}
EXEC = reaper
all: ${SRC} ${OBJ} ${EXEC}
${EXEC}: ${OBJ}
${CC} ${LDFLAGS} $^ -o $#
%.o: %.c ${HDR}
${CC} ${CFLAGS} $< -o $#
clean:
rm src/*.o ${EXEC}.exe
when I run make clean gives me this Error:
rm src/*.o reaper.exe
process_begin: CreateProcess(NULL, rm src/*.o reaper.exe, ...) failed.
make (e=2): The system cannot find the file specified.
make: *** [Makefile:18: clean] Error 2
How can I fix it?
I have some troubles with my make file. All the output files are generated, but linking is not possible. Therefore, I don't get the output executable. Where is my mistake?
Here is my recipe for the output file:
gcc main.o memory.o startup_msp432p401r_gcc.o system_msp432p401r.o interrupts_msp432p401r_gcc.o -Wall -Werror -g -O0 -std=c99 -DHOST -MM -Wl,-Map=c1m2.map -T msp432p401r.lds -o c1m2.out
And here is the whole makefile:
ifeq ($(PLATFORM),HOST)
CC = gcc
else
CC = arm-none-eabi-gcc
endif
# Architectures Specific Flags
LINKER_FILE = msp432p401r.lds
CPU = cortex-m4
ARCH = mthumb
SPECS = nosys.specs
# Compiler Flags and Defines
LD = arm-none-eabi-ld
ifeq ($(PLATFORM),MSP432)
CFLAGS = -Wall -Werror -g -O0 -std=c99 -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfloat-abi=hard -mfpu=fpv4-sp-d16 --specs=nosys.specs
LDFLAGS = -T msp432p401r.lds
else
CFLAGS = -Wall -Werror -g -O0 -std=c99 -DHOST
LDFLAGS = -Wl,-Map=$(TARGET).map -T msp432p401r.lds
endif
TARGET = c1m2
CPPFLAGS = -MM
OBJS = $(SOURCES:.c=.o)
%.o: %.c
$(CC) $< $(CFLAGS) $(CPPFLAGS) -o $#
.PHONY: build
build: all
.PHONY: all
all: $(TARGET).out
$(TARGET).out: $(OBJS)
$(CC) $(OBJS) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) -o $#
.PHONY: clean
clean:
rm -f $(OBJS) $(TARGET).out $(TARGET).map
Thank you very much!
I have the following makefile. When I run "make" or "make all", I get the following output:
make all -n

Issue is: I don't see the following line executed:

I figured this out. The line $(CXX) did not start with a tab; had 8 spaces instead. Once I introduced tabs, it worked just fine. Thanks all!
I am kind of new in the use of make.
I have a library written in C which is in the folder folder1
Where these files are there is also a makefile which is the following:
PREFIX ?= /usr/local
CC = gcc
AR = ar
CFLAGS = -std=gnu99 -fPIC -Wall -Wno-unused-parameter -Wno-unused-function -I. -O4
APRILTAG_SRCS := $(shell ls *.c common/*.c)
APRILTAG_HEADERS := $(shell ls *.h common/*.h /usr/include/flycapture/*.h)
APRILTAG_OBJS := $(APRILTAG_SRCS:%.c=%.o)
TARGETS := libapriltag.a libapriltag.so
.PHONY: all
all: $(TARGETS)
#$(MAKE) -C example all
.PHONY: install
install: libapriltag.so
#chmod +x install.sh
#./install.sh $(PREFIX)/lib libapriltag.so
#./install.sh $(PREFIX)/include/apriltag $(APRILTAG_HEADERS)
#sed 's:^prefix=$$:prefix=$(PREFIX):' < apriltag.pc.in > apriltag.pc
#./install.sh $(PREFIX)/lib/pkgconfig apriltag.pc
#rm apriltag.pc
#ldconfig
libapriltag.a: $(APRILTAG_OBJS)
#echo " [$#]"
#$(AR) -cq $# $(APRILTAG_OBJS)
libapriltag.so: $(APRILTAG_OBJS)
#echo " [$#]"
#$(CC) -fPIC -shared -o $# $^
%.o: %.c
#echo " $#"
#$(CC) -o $# -c $< $(CFLAGS)
.PHONY: clean
clean:
#rm -rf *.o common/*.o $(TARGETS)
#$(MAKE) -C example clean
Then, in the folder example I have some example which I can just run by giving the following command in the terminal:
./opencv_demo
or
./apriltag_demo
In this folder example I have another makefile which is the following:
CC = gcc
CXX = g++
CPPFLAGS = -I..
CFLAGS = -std=gnu99 -Wall -Wno-unused-parameter -Wno-unused-function -O4
CXXFLAGS = -Wall -O4
LDFLAGS = -Lusr/include/flycapture -lpthread -lm
INC_DIR = /usr/include/flycapture
TARGETS := apriltag_demo opencv_demo
.PHONY: all
all: apriltag_demo opencv_demo
apriltag_demo: apriltag_demo.o ../libapriltag.a
#echo " [$#]"
#$(CC) -o $# $^ $(LDFLAGS)
opencv_demo: opencv_demo.o ../libapriltag.a /usr/include/flycapture/Error.h
#echo " [$#]"
#$(CXX) -o $# $^ $(LDFLAGS) `pkg-config --libs opencv`
%.o: %.c
#echo " $#"
#$(CC) -o $# -c $< $(CFLAGS) $(CPPFLAGS)
%.o: %.cc
#echo " $#"
#$(CXX) -o $# -c $< $(CXXFLAGS) $(CPPFLAGS)
.PHONY: clean
clean:
#rm -rf *.o $(TARGETS)
If I do make in the folder1 I get the following error:
opencv_demo.o: In function `main':
opencv_demo.cc:(.text.startup+0x24e): undefined reference to `FlyCapture2::Error::Error()'
opencv_demo.cc:(.text.startup+0x2a7): undefined reference to `FlyCapture2::Error::~Error()'
opencv_demo.cc:(.text.startup+0x11a0): undefined reference to `FlyCapture2::Error::~Error()'
collect2: error: ld returned 1 exit status
make[1]: *** [opencv_demo] Error 1
make[1]: Leaving directory `/home/fschiano/Repositories/apriltag2/example'
make: *** [all] Error 2
If I am not wrong this error tells me that I did not include a library.
In the file opencv_demo.cc I did:
#include "flycapture/FlyCapture2.h"
#include "flycapture/Error.h"
using namespace FlyCapture2;
Headers which are in /usr/include/flycapture a folder which contains all the headers needed for what I need in the file opencv_demo.cc.
I don't know why it is not working, someone is able to help me?
I think I should write in the makefile where to search for the libraries but I don't know how.
I tried to write the following things in the makefile separately but they are not working :
LDFLAGS = -Lusr/include/flycapture -lpthread -lm
INC_DIR = /usr/include/flycapture
DEPS = $(INC_DIR)/Error.h
I'm trying to compile cryptopp with gcc49 on FreeBSD 10.x, however no matter how I instruct the Makefile to compile with g++49/gcc49, my attempts are ignored and it always compiles with c++.
I can't see at the moment where the compiler is defined in Makefile.
What I tried:
ifeq ($(CXX),gcc) # for some reason CXX is gcc on cygwin 1.1.4
CXX = g++49
endif
So I'd like the almighty of someone here to instruct it to compile with gcc49 (or g++49?) instead. Thanks!

If I recall correctly, CXX is g++ or c++ on the BSDs, so you will never enter the ifeq block.
The easiest thing to do would probably be:
# GNUmakefile
CXXFLAGS = -DNDEBUG -g -O2 -fPIC
CXX=g++49
...
It looks like you are using Crypto++ 5.6.2 or less because of this line:
CXXFLAGS = -DNDEBUG -g -O2
5.6.3 and above works harder at honoring user's preferences. For example, in 5.6.3 GNUmakefile (which is being tested for release):
# Base CXXFLAGS used if the user did not specify them
CXXFLAGS ?= -DNDEBUG -g2 -O2
The next-easiest thing to do would be to grab the 5.6.3 GNUmakefile, and then peform the following (g++49 must be on-path):
export CXX=g++49
make
I can assure you that works on 5.6.3 because I made the changes to facilitate testing under different compilers. You can also tweak CXXFLAGS:
export CXX=/opt/intel/bin/icpc
export CXXFLAGS="-DNDEBUG -g2 -O3 -wd68 -wd186"
make
5.6.3 should be available in a couple of weeks. We are finishing up the mitigations for a Coverity scan/analysis. Once they are mitigated, we have to perform a final round or Release Testing.
