I'd like to write a Makefile for my CUDA/C++ code but I didn't know how things work with CUDA, I mean there is a nvcc compiler but I don't know what I've got to do with this.
Do I have to firstly run nvcc and then g++ or only nvcc to compile my CUDA/C++ code ? I found nothing on the web explaining such basic things .
I've been trying to work out a way to stop chunks of code being compiled using a variable in my makefile but can't work it out. What I mean is for example in my code I might have.
/****output comms portdata********/
printf("
debug comms port %d",ReadPort("ttys1);
I only wish this code to be compiled when I'm debugging. What I've tried is using #ifdef with
#ifdef COMM_PORT_DEBUG
printf("
debug comms port %d",ReadPort("ttys1);
#endif
Then in my make file I set COMM_PORT_DEBUG to 1 so
DEBUG_DEFS = COMM_PORT_DEBUG=1
I then thought I could put it into my in my link line
all: $(CC) $(CPFLAGS) $(DEBUG_DEFS) $(INC_PATHS) $(SOURCE) -o $(PROGRAM) $(LIB_DIRS) $(GAME_LIBS)
but this gives a
gcc: COMM_PORT_DEBUG=1: No such file or directory
is there a way to do this sort of thing? Or am I barking up the wrong tree?

How do you write a program that is independent of the UI (the functionality is a library, and you have, for example, CLI and GUI interfaces as separate apps). The problem I have is how to report status and prompt the user from within UI-independent code? I could split it into parts that do not require any user interaction, but then most of the functionality will be in the UI, not the backend.

Can afterwards copy and paste and use someone's comments format or this is might some copyright problem?

I am a beginner in Linux. Never did any kernel programming in Linux/Windows before. I am now on a project and I am supposed to understand a Linux Device Driver Code. It contains 6 .c files and 1 Makefile.
The make file goes as this:
I have a.c b.c c.c d.c d.c e.c f.c in the director along with the Makefile mentioned.

View 3 Replies View RelatedI'm trying to figure out how Make handles directories.
How can I modify this makefile so it will put all of the .o files in a separate build directory?
Code:
But make ignores this and still puts main.o in the base directory. And if I refer to the build directory in the dependencies for bandit, make complains about "no rule ..."
I want to keep main.cpp in the base directory, all other sources in the src directory, and all object files in the build directory.
When I put a "test" target in my Makefile containing
Code:
@echo "CXX= $(CXX)"
it tells me "CXX= g++".
But I have nothing in the Makefile assigning any value to CXX, and as far as I can tell I have no CXX environment variable (no "CXX" appears when I run the shell command "env", and "echo $CXX" returns a blank line. So where's the g++ value coming from. Is this just built into Gnu Make, or is there a configuration file for make somewhere?
i need to make a to-do list for my project, everything is fine so far. but i really dont have a clue on writtiing this part: we need to write a programme that takes input from a text file then either encrypt or decrpyt it. according to the ASCII code of this charecters the user should give us his/her own keyword then the program will save the output in a new file .

I am trying to run a script to setup environment variables and then run other commands in a make file. But the source or the dot operator (shell is bash) does not seem to take any effect as the subsequent command didn't pick the environment up. Do I have to put every lines of the environment setup in the first script into the makefile instead?
sample setenv.sh
#!/bin/sh
export MYDIR=/somedir
sample makefile:
all: source ./setenv.sh
echo $(MYDIR)
I'm learning about how to write Makefiles, and am a bit lost at how to run a command in a target depending on the value of a variable.
What I'm trying to do, is run "strip" only if the user is running a given version of a C compiler.
Here's the code:
Code:
$(LUA_T): $(LUA_O) $(LUA_A)
$(CC) -o $@ $(MYLDFLAGS) $(LUA_O) $(LUA_A) $(LIBS)
#FDPIC ELF binaries can be stripped, but not FLAT binaries
$(if($(CROSS),bfin-linux-uclibc-),
$(STRIP) $@
;)
Does someone know the correct way to do this?

I am trying to use a software package written in ANSI C. It has a makefile which has to be executed first.
As soon as I execute it I get messages like: line i: command not found.
Commands for which I am getting errors :
CC = /usr/bin/gcc
GCCFLAGS = -c -Wall
ROOTDIR = .
My gcc compiler is located in the above directory only. In ROOTDIR also I tried giving the path in which all the required files & folders are present but still I get the command not found error in all the lines.
I created a quick makefile with the following lines:
Code:
$(BINARY):
echo "----- Linking $(BINARY)----"
gcc -m32 -g src/* -Iinclude -I$(HOME)/include -I$(HOME)/include2 -D_LINUX -DSYSV -DPOSIX -L$(HOME)/shared/lib32 -lidlib -lid2lib -o bin/sampleapp
echo "---- done ----"
It builds fine when I build from the command line ( make -f sample.mk).
However, it does not build when building from eclipse (which essentially calling the same makefile). The make output shows exactly the same as what I got from the command line build, except the last line showing
Code:
collect2: cannot find 'ld'
make: *** [sampleapp] Error 1
I am not sure why it tries to call "ld" when building from eclipse.
So I have been trying for 8 hours to try to get the index of an element from a list in a Makefile. The problem is that after I get the index using all the methods I have tried, the index cant be used in the "word" function:
for instance:
$(OUTPUT2) : INDEX = $(shell echo $(OUTPUT2) | sed -r -e "s/[ ]+/
/g" | grep -n $@ | sed 's/^([0-9]*):.*/1/')
will create a variable INDEX defined specifically for each member of OUTPUT2, so that each output knows its index. Unfortunately, when I pass this $(INDEX) into word, it doesn't work:
$(OUTPUT2) : $(word $(INDEX), $(INPUT1)) $(word $(INDEX), $(INPUT2))
echo $(INAME) $(TMPBASE) $@
and I get the error:
Makefile:16: *** non-numeric first argument to `word' function: 'num'. Stop.
I feel like if I could just convert a string to a Makefile acceptable number this would just work....

I know how to manually writing a makefile for my project, but I am new in using makefile & configure file generation tools like automake to generate a makefile and a configure script file.
I had done research on tutorials for generating makefile and configure script file.
I know that I need to manually write two files (makefile.am and configure.in).
I use wxWidgets GUI library, libconfig library, and libpcap library to do my project.
wx-config is a tool that can return the library files and include directory for wxWidgets library.
