So, client.o and server.o are not being compiled... but the make file doesn't error...
I've checked the directory where all the code is and the sub folders. but client and server .o just aren't there... =\
here is my make file:

g++ -c src/cloud/chat_client.cpp will build an object file called chat_client.o, not client.o. Either add -o $# to the rule to create an object file with the same name as the target, or rename the file to chat_client.o everywhere it's mentioned in the makefile.

I am trying to run makefile but I cant make him find the files I add to it unless I put full path of the file: /home/"user_name"/CLionProjects/Ass1/src/main.cpp
I try to run the makefile when I am in Ass1 so as much that I understand the makefile should find the main.cpp .
Would love to know where I am wrong here, thank you.

If I'm inserting the paths like:
#include "../../libcurl-7.56.0/include/curl/curl.h"
instead of:
#include <curl/curl.h>
then it works but I cant change it for all includes.
Here's the Tree:

So I just got through a bunch of compiler issues and finally make runs well for the most part, however now I am getting an error
g++ prog4.cc
g++ -o lextest prog4.o Lexer.o Token.o
g++: prog4.o: No such file or directory
make: *** [lextest] Error 1
This is my makefile
OBJ = prog4.o Lexer.o Token.o
LEXER = Lexer.cc Lexer.h
TOKEN = Token.cc Token.h
OPTS = -g -c -Wall -Werror
lextest: $(OBJ)
g++ -o lextest $(OBJ)
prog4.o: prog4.cc $(LEXER) $(TOKEN)
g++ $(OPTS) prog4.cc
Lexer.o: Lexer.cc Lexer.h
g++ $(OPTS) Lexer.cc
Token.o: Token.cc Token.h
g++ $(OPTS) Token.cc
clean:
rm -f *.o *~
Can anyone see any obvious errors in the makefile or would this error be generated by an issue in prog4.cc?
Pretty new to C++, so I hope this is just some simple error that I can fix.
Thanks!
You are missing the -c and -o options to g++
g++ -c -o prog4.o $(OPTS) prog4.cc
I am doing a c++ project with multiple source files and trying to get used to using makefiles. I want to be able to debug this program with gdb. If I use the following command in Terminal to compile, it works fine:
g++ -o main -g *.cpp
But if I just call make it doesn't generate a debug file (the .dSYM file) even though it compiles the program fine. I assume this has something to do with creating the individual object files first. Here is my makefile:
all: main.o sort.o bubble.o quickSort.o rbs.o
g++ -g -o main *.o -Wall -O2
main.o: main.cpp
g++ -c main.cpp
sort.o: sort.cpp sort.h
g++ -c sort.cpp
bubble.o: bubble.cpp bubble.h
g++ -c bubble.cpp
quickSort.o: quickSort.cpp quickSort.h
g++ -c quickSort.cpp
rbs.o: rbs.cpp rbs.h
g++ -c rbs.cpp
clean:
rm *.o
How do I create the main.dSYM debug file when using a makefile like this?
If you want the debug files, you must compile all of the components with -g.
The crude way to do this would be to add -g to every object rule:
all: main.o sort.o bubble.o quickSort.o rbs.o
g++ -g -o main *.o -Wall -O2
main.o: main.cpp
g++ -c -g main.cpp
sort.o: sort.cpp sort.h
g++ -c -g sort.cpp
bubble.o: bubble.cpp bubble.h
g++ -c -g bubble.cpp
quickSort.o: quickSort.cpp quickSort.h
g++ -c -g quickSort.cpp
rbs.o: rbs.cpp rbs.h
g++ -c -g rbs.cpp
But that doesn't leave you the option of building without debug information. And there's a lot of redundancy in this makefile. Let's take this in stages. First, we put in automatic variables to simplify the rules:
all: main.o sort.o bubble.o quickSort.o rbs.o
g++ -g -o main $^ -Wall -O2
main.o: main.cpp
g++ -c -g $<
sort.o: sort.cpp sort.h
g++ -c -g $<
bubble.o: bubble.cpp bubble.h
g++ -c -g $<
quickSort.o: quickSort.cpp quickSort.h
g++ -c -g $<
rbs.o: rbs.cpp rbs.h
g++ -c -g $<
Now we see that all of the *.o rules have the same command, which reminds us that Make already knows how to build foo.o from foo.cpp, with a command that looks like:
$(CXX) $(CPPFLAGS) $(CXXFLAGS) -c
So all we have to do is add -g to CXXFLAGS, and we can omit the commands entirely:
CXXFLAGS += -g
all: main.o sort.o bubble.o quickSort.o rbs.o
g++ -g -o main $^ -Wall -O2
sort.o: sort.h
bubble.o: bubble.h
quickSort.o: quickSort.h
rbs.o: rbs.h
Now that that's in order, we can set up two top-level targets, main and debug, and change CXXFLAGS only for the latter:
debug: CXXFLAGS += -g
main debug: main.o sort.o bubble.o quickSort.o rbs.o
g++ -g -o $# $^ -Wall -O2
sort.o: sort.h
bubble.o: bubble.h
quickSort.o: quickSort.h
rbs.o: rbs.h
You can improve this even more, but that should get you started.
I am making a makefile and one of the targets is exptrtest.o how do I use g++ to create an objectfile with that name, the name of my cpp file is exprtest.cpp not exptrtest.cpp?
exptrtest.o: exprtest.cpp
g++ -Wall -g -c exprtest.cpp
to make it more clear, this is my makefile:
all: exprtest
exprtest: exptrtest.o driver.o parser.tab.o scanner.o
g++ -Wall -g -o exprtest exptrtest.o driver.o parser.tab.o scanner.o
exptrtest.o: exprtest.cpp
g++ -Wall -g -c exptrtest.o exprtest.cpp
driver.o: driver.cpp scanner.hpp driver.hpp
g++ -Wall -g -c driver.cpp
parser.tab.o: parser.tab.hpp parser.tab.cpp
bison parser.ypp
g++ -Wall -g -c parser.tab.cpp
scanner.o: scanner.cpp scanner.hpp
flex -t scanner.ll > scanner.cpp
g++ -Wall -g -c scanner.cpp
clean:
rm parser.tab.hpp parser.tab.cpp scanner.cpp
I'm getting the error:
"g++: error: exptrtest.o: No such file or directory
make: * [exprtest] Error 1"
Use the -o option in conjunction with -c.
exptrtest.o: exprtest.cpp
g++ -Wall -g -c exprtest.cpp -o exptrtest.o
