Here's my makefile:
assemblera: main.o parsingA.o parsingC.o symbolTable.o
gcc -o assemblera main.o parsingA.o parsingC.o symbolTable.o
main.o: main.c parsingA.h parsingC.h symbolTable.h
gcc -c main.c
parsingA.o: parsingA.c parsingA.h
gcc -c parsingA.c
parsingC.o: parsingC.c parsingC.h
gcc -c parsingC.c
symbolTable.o: symbolTable.c symbolTable.h
gcc -c symbolTable.c
clean:
rm *.o assemblera
Now for the problem: with Windows command prompt I can easily generate all the .o files and .exe file, and if I run the latter it works as intended. Now, if I use the cygwin terminal, I can give the instructions to generate the object files / the exe, but those do not appear nowhere in the folder and no error is returned. Also, if I use the make command, it returns this error:
gcc -c main.c
make: *** [Makefile:5: main.o] Error 1
(I did put tabs in front of every "gcc" and "rm"). I know next to nothing about makefiles and cygwin.

I am trying to run some old Fortran code of my project team in ubuntu 16.04. I have not done any modifications to the existing code. All I have done is installed gfortran, opened a terminal, and gone to the file location using the cd command. Here I have many files, but just consider these two: a script file compile.sh, and a makefile remail.make.
In compile.sh:
make -f remail.make
In remail.make:
SOURCE_APPLI= ../SOURCES_COUNTERFLOW/
$(SOURCE_APPLI)grcom.f
TARGET = remail.e
OBJECTS = $(SOURCES_f77:.f=.o)
COMPILE = f90
.f90.o :
$(COMPILE) -o $*.o -c $*.f90
.f.o :
$(COMPILE) -o $*.o -c $*.f
$(TARGET) : $(OBJECTS)
$(COMPILE) $(OBJECTS) -o $#
del :
$(DELETE) $(OBJECTS)
When I run compile.sh, I get this error:
f90 ../SOURCES_COUNTERFLOW/grcom.o -o remail.e
make: f90: Command not found
make: *** [remail.e] Error 127
I have installed fort77 and gfortran-4.8 compilers.
What is the reason for this error?
The problem was that I was not using the correct executable.
For example, In my case, I installed fort77 and gfortran-4.8 and the executable was saved in the name as fort77 and gfortran-4.8.
The reason for my error was that I was calling these two executables as fort77 and gfortran instead of fort77 and gfortran-4.8.
When I called fort77 and gfortran-4.8 correctly in the terminal, it works!!
I'm trying to learn how to write makefiles. I have started reading the manual of gnu make: https://www.gnu.org/software/make/manual/html_node/Simple-Makefile.html#Simple-Makefile
I have 3 files in the same directory:
main.cpp: which creates a rectangle and prints some information. Therefor it includes Rectangle.h
Rectangle.h: header file for rectangle class
Rectangle.cpp: implementation of rectangle class
I am having troubles with the include of Rectangle.h in main.cpp. My makefile is:
main: main.o rectangle.o
g++ -o main.exe main.o rectangle.o
main.o: main.cpp
g++ main.cpp
rectangle.o: Rectangle.cpp
g++ Rectangle.cpp
clean:
rm main.exe main.o rectangle.o
I know something is missing to create main.o but I can't find out what it is. I tried adding various variations of Rectangle.h/.o/.cpp and finding something on the internet but I was unable to find something.
Help will be much appreciated :)
PS: The code is fine, I can compile it with the command:
g++ -o main.exe main.cpp Rectangle.cpp
man g++
When you invoke GCC, it normally does preprocessing, compilation, assembly and linking. The "overall options" allow you to stop this process at an intermediate stage. For example, the -c option says not to run the linker. Then the output consists of object files output by the assembler.
I recently tried to make a makefile and it works fine on my laptop. I was making a game in c++ and shared my code on github. One of my friends cloned
the repo and informed me that he ran into some errors. Coming to errors I must inform you that my project uses QuickCG which is based on SDL, so naturally one needs to have SDL installed. My friend did not have that initially but later downloaded it using sudo apt-get install libsdl1.2-dev. After downloading, the 'header include' error was removed but still there is linking error I suppose.
Here is my makefile
CC = g++
CFLAGS = -c -O3
CLINK_FLAGS = -lSDL
all : game
game : main.o quickcg.o
$(CC) main.o quickcg.o -o game $(CLINK_FLAGS)
main.o : main.cpp
$(CC) $(CFLAGS) main.cpp
quickcg.o : quickcg.cpp
$(CC) $(CFLAGS) quickcg.cpp
clean :
rm *.o game
My Game folder contains only 2 cpp files which are main.cpp and quickcg.cpp. It also contains 1 header file quickcg.h
Now to come to the exact error statement after executing make
g++ -c -O3 main.cpp
g++ -c -O3 quickcg.cpp
g++ main.o quickcg.o -o game -lSDL
/usr/bin/ld: cannot find -lSDL
collect2: error: ld returned 1 exit status
make: *** [game] Error 1
Please note that this worked completely fine on my laptop.
Also please note that the following command worked like a charm even on his laptop
g++ *.cpp -lSDL -O3
So clearly there seems to be a fault with makefile.
Forgive me if I have done anything stupid because I am new to makefiles but I am not able to find any errors here. Thanks in advance
You may try
CLINK_FLAGS = `sdl-config --libs`
if you don't know the path for -L.
I have a makefile that contains this code
all: hello.exe
hello.exe: hello.o
gcc -o hello.exe hello.o
hello.o: hello.c
gcc -c hello.c
clean:
rm hello.o hello.exe
When i write this command
mingh32-make
I got this:
mingw32-make : *** No targets specified and no makefile found. Stop.
You can solve this in 2 ways.
As the commenters say, rename your file from makefile.txt to makefile.
Another way, use mingw32-make -f makefile.txt
I am having trouble compiling using make in windows 7 with gcc and the gsl library. It occurs only when using make (when I type the compilation commands manually into the cmd line, it compiles correctly). I found some posts where people had similar errors from gcc, but none where it worked when typing normally, but not when using make. The contents of my Makefile are shown below:
#Compiler
COMP=gcc
# Compiler Flags. -Wall turns on all warnings
FLAGS=-Wall
# GSL include file dir
INCLUDES=GnuWin32/include
# GSL Libraries directory
LIB=GnuWin32/lib
# Library Flags
LFLAGS=-lgsl -lgslcblas -lm
# Target Program
EXE=ex2.1.exe
# Dependencies needed for $(PROGRAM)
OBJ=ex2.1.o
# List of source files for objects
SRC=ex2.1.c
# List with types of files to be cleared by clean:
TRASH=*.exe *.o
# I/O files to be cleaned with 'very clean' target
#IOFILES= *.dat *.out *.csv *.mod
all: $(SRC) $(EXE)
$(EXE): $(OBJ)
$(COMP) -L/$(LIB) $(OBJ) $(LFLAGS) -o $(EXE)
$(OBJ): $(SRC)
$(COMP) -I/GnuWin32/include -c ex2.1.c
#$(COMP) -I/$(INCLUDES) -c $(SRC)
clean:
del $(TRASH)
If I type make with only the ex2.1.c present in the directory, I get the following output and error:
gcc -I/GnuWin32/include -c ex2.1.c
gcc: error: CreateProcess : No such file or directory
make: *** [ex2.1.o] Error 1
However, if I first type "gcc -I/GnuWiun32/include -c ex2.1.c", ex2.1.o is created successfully with no error. If then type 'make' I get the following output/error:
gcc -L/GnuWin32/lib ex2.1.o -lgsl -lgslcblas -lm -o ex2.1.exe
gcc: fatal error: -fuse-linker-plugin, but liblto_plugin-0.dll not found
compilation terminated
make: *** [ex2.1.exe] Error 1
But if I manually enter "gcc -L/GnuWin32/lib ex2.1.o -lgsl -lgslcblas -lm -o ex2.1.exe" then the executable compiles and runs like it should, so the problem seems to be with how make is calling gcc? My PATH variable contains the paths to both make.exe as well as gcc.exe, so I am not sure what I do not set up correctly. Does anyone have an idea of what may be wrong? Thanks.
