I have a problem when I execute commmand "make" in terminal ubuntu.
My code of makefile is:
all: temp p1
%: %.cc g++ -lm -lcrypt -O2 -std=c++11 -pipe $< -o $#
Of course, my files are temp.cc and p1.cc, but my problem is in p1.cc, where the code is:
#include <bits/stdc++.h>
using namespace std;
int main(){
vector<int> vec = {4,6,8,9,8,7,1,3,4,5,0,1};
for(auto i : vec)
cout<<i<<" ";
cout<<endl;
return 0;}
My error using 'make' is:
eabg97#EABG:~/P$ make
g++ p1.cc -o p1
p1.cc: In function ‘int main()’:
p1.cc:7:44: error: in C++98 ‘vec’ must be initialized by constructor, not by ‘{...}’
vector<int> vec = {4,6,8,9,8,7,1,3,4,5,0,1};
^
p1.cc:7:44: error: could not convert ‘{4, 6, 8, 9, 8, 7, 1, 3, 4, 5, 0, 1}’ from ‘<brace-enclosed initializer list>’ to ‘std::vector<int>’
p1.cc:9:11: error: ‘i’ does not name a type
for(auto i : vec)
^
p1.cc:11:2: error: expected ‘;’ before ‘cout’
cout<<endl;
^
p1.cc:12:2: error: expected primary-expression before ‘return’
return 0;
^
p1.cc:12:2: error: expected ‘)’ before ‘return’
make: *** [p1] Error 1
Using the next command lines, compile:
g++ --std=c++11 p1.cc -o p1
and executing is okay:
eabg97#EABG:~/P$ ./p1
4 6 8 9 8 7 1 3 4 5 0 1
Please help me, I don't understand why there is a problem, thanks for your support :)
This is wrong:
all: temp p1
%: %.cc g++ -lm -lcrypt -O2 -std=c++11 -pipe $< -o $#
You should either add a newline and an initial TAB, like this:
all: temp p1
%: %.cc
g++ -lm -lcrypt -O2 -std=c++11 -pipe $< -o $#
(the first char on the third line must be a TAB character) or you need to insert a semicolon like this:
all: temp p1
%: %.cc ; g++ -lm -lcrypt -O2 -std=c++11 -pipe $< -o $#
What is your makefile doing? First, that statement all in one line without any newline/TAB or semicolon is considered by make to be a single pattern rule with a target % and prerequisites %.cc, g++, -lm, -lcrypt, etc. And, since there's no recipe, you're basically deleting that pattern rule (which doesn't exist anyway) since a pattern rule with no recipe deletes the pattern rule. So that line is essentially a no-op and does nothing.
So what happens? Make has a bunch of built-in rules that it uses to create things if you don't tell it how to do so, and there's a built-in rule that knows how to create a program from a .cc file, so make uses that. But of course, that built-in rule doesn't have any of your customizations.
It's simpler to use make's built-in rule and use the standard make variables to control it:
CXX := g++
CXXFLAGS := -std=c++11 -pipe
LDLIBS := -lm -lcrypt
all: temp p1
That's all you need, if you don't want to write your own rule.
Here is my makefile, until today I never try to use OS detection in it. Mine looks like this :
CC = gcc
CFLAGS = -Wall -Wextra -O1 -Wuninitialized
OUT = project.exe
ifeq ($(UNAME),Darwin) #Mac OS
echo "Darwin"
SRC = sdl_gui.c libSDLextra.c libImageProcessing.c SDLmain.m
OBJ = sdl_gui.o libSDLextra.o libImageProcessing.o SDLmain.o
LIBS = -I /Library/Frameworks/SDL.framework/Headers -framework SDL -I /Library/Frameworks/SDL_ttf.framework/Versions/A/Headers -framework SDL_ttf -framework Cocoa
endif
ifeq ($(UNAME),Linux) #Linux based systems
SRC = sdl_gui.c libSDLextra.c libImageProcessing.c
OBJ = sdl_gui.o libSDLextra.o libImageProcessing.o
LIBS = -lSDL -lSDL_ttf
endif
all : $(OUT)
$(OUT) : $(OBJ)
$(CC) $(CFLAGS) $(OBJ) -o $(OUT)
$(OBJ) : $(SRC)
$(CC) $(CFLAGS) -c $(SRC)
clean :
rm -f $(OBJ) $(OUT)
When I do make I've got this error :
gcc -Wall -Wextra -O1 -Wuninitialized -o projet.exe
clang: error: no input files
make: *** [projet.exe] Error 1
I understand the error but I don't know how to fix it.
It looks like you are missing this from (near) the top of the file:
UNAME := $(shell uname)
I have succeeded in creating static libraries from my source files using CMake. Now I need to create quite a few executables using these libraries. I have read the CMake examples and attempted to duplicate what they had listed but did not seem to work. I am receiving the error:
Linking CXX executable ../../build/bin/discoveryService
armv5l-timesys-linux-uclibcgnueabi-g++: CMakeFiles/discoveryService.dir/discoveryService.cpp.o: linker input file unused because linking not done
Here is a quick overview of my directory structure. Each directory creates a static library from the source files included in that directory. Most directories also need to generate executables which rely on libraries within the 633/arm directory:

I'm having trouble compiling wmii v3.9.2 on Fedora 15; Here's the interesting part (things break down at the linking stage):

Finally, in config.mk, I have the following settings:

LIBS = -L$(ROOT)/lib -L/usr/lib64
...
LDFLAGS += -g $(LIBS)
SOLDFLAGS += $(LDFLAGS)
SHARED = -shared -Wl,-soname=$(SONAME)
STATIC = -static
...
With a little more manual resolution, the statement generating the error is essentially as follows:
gcc \
-o wmii9menu.out\
-L../lib -L/usr/lib $(pkg-config --libs xft xrandr xinerama xext)\
../lib/libregexp9.a ../lib/libbio.a ../lib/libfmt.a\

wmii9menu.o clientutil.o util.o\
wmii/x11.o wmii/xext.o wmii/geom.o wmii/map.o
Here, the pkg-config resolves to the following, which by itself is perfectly correct:
-lXft -lXrandr -lXinerama -lXext
And the solution is as follows:

I'm trying to debug an issue with a makefile I am working on.. What is confusing is that the target works when I run it from the command line, but does not work in my makefile..
Here is the makefile:

$(NDDSHOME)/scripts/rtiddsgen ${IDL_DIR}/$# -d $(DDS_OUT_DIR) -I ${IDL_DIR} -replace -language C++;
if I just do this:
make
The %.idl target is called fine, when that finishes I get this output:
Generating CXX from common.idl ... obj.Linux-i686/commonSupport.o obj.Linux-i686/commonPlugin.o obj.Linux-i686/common.o
Running rtiddsgen version 4.5d, please wait ...
Done
make: *** No rule to make target `obj.Linux-i686/commonSupport.o', needed by `default'. Stop.
But then when I re-run it and everything compiles, so it works fine...
Why is this not working in one step?
commonSupport.cxx seems to depend on common.idl. Tell this to make.
commonSupport.cxx: common.idl
#echo "Generating CXX from $# ..." $(GENERATED_OBJS); \
$(NDDSHOME)/scripts/rtiddsgen ${IDL_DIR}/$# -d $(DDS_OUT_DIR) -I ${IDL_DIR} -replace -language C++;
Or, to ensure all dependencies are right:
$(GENERATED_SOURCES): common.idl
.... steps to make GENERATED_SOURCES from common.idl
