How To Run Executable Files?

Hello,

I am working on a board (sbc6000x with at91sam9261 micro, linux 2.6.24 to be precise) and having some fun making script i wanted to make real application.
The board is coming with a cross compilation toolchain. When trying to make a simple "hello world" executable to print on the terminal there is no problem.
I open my terminal, give the path of the compiler, cd into the folder where my .c file is and then i type :
Code:

arm-linux-gcc -o hello hello.c

Which create my executable "hello" and this one is working. But like i said, this program only played with the terminal.

The board is starting with a script calling another executable which use the lcd display, i have the source of this executable. My idea was to look at what was in the source of this application (lots of folders and files) in order to understand how it was working. I wanted to test the toolchain on the source (with the makefile) to see if i was able to generate an executable from a application with folderS/fileS but when i try to "make" it i have this error.

In my understanding this is an object file but aside from that i don't see why it would not works.

Thank you for your future answers !

Hi Experts:

I'm new to Linux,recently i was confused with the words as below:

"To achieve sharing,the process A mmaps the executable file of process B into into the virtual address space of process A. As the Linux loader maps the executable files into the process when executing them,the two processes share the memory image of the mapped file"

questions:
1,What are the "executable files",are they ELF files?
2,How to do "mmaps"？if process A and process B share the same code segment, ,where is process A's own code segment?


Thank you in advance.

Hi, I'm trying to run an executable file on a remote server using Putty? I downloaded PuTTY and connected through the Putty Configuration window with the SSH connection type selected. Once I connected, the cmd window disappeared so I assume I'm connected. Now I want to run an executable file on the remote server.

How can I run an executable file on my remote Linux server using Putty?

Thanks for any help with this.

Fresh Newbie to Linux. Used to be good at DOS commands. Used Norton Commander a lot. Now have to learn the ins and outs of Linux. Need help with subject. Thanks.

Brand-spankin' new newbie here, and I can't figure out how to open my files I've downloaded. I've downloaded some .exe's, but can't figure out how to open them, and haven't found anyplace via Google that can help with this fundamental problem. I know this is obviously a simple issue, but I can't figure it out and am very frustrated!!! I totally appreciate any constructive feedback, thanks much. Steve

I have a directory w/ a file that I created using:
Code:

fd = open("file", O_CREAT);

The file turned out to be executable. When I did a 'ls -l' on the directory w'/ that file it has a "T" at the end of the permissions where the executable bit would be set for the "other" group.

Hi,
I am working with Debian and gcc.

I have a single C file main.c, with some code in it.
For this trivial build, I am using the following Makefile:

Code:

SOURCES=main.c
CFLAGS=-c -w -gdwarf-4 -g3 -O0

LDFLAGS=
CC=

OBJECTS=$(SOURCES:.c=.o)
EXECUTABLE=myprogram

all: clean $(SOURCES) $(EXECUTABLE)

$(EXECUTABLE): $(OBJECTS)
	$(CC)gcc $(LDFLAGS) $(OBJECTS) -o $@

clean:
	rm -f $(EXECUTABLE) $(OBJECTS) $(MAKE)

.c.o:
	$(CC)gcc $(CFLAGS) $(LDFLAGS) $< -o $@

Now, in main.c, I want to use an assembly function, say myFunction which is implemented in the file function.asm.

My question is now: how do I build this? How do I modify the Makefile above to do this ?

Many thanks for your help!!!

PD.

I was trying to write a simple menu using the "dialog" function only to find out that the version of linux i am running (I have previously worked on HP/Sun/ICL/AIX versions of unix)does not have the "dialog exe" and the one that someone has put on this box is not compatible.As follows:-

file /dir/dir/dir/dailog Retruns:-
dialog: ELF 32-bit MSB executable, SPARC, version 1 (SYSV), dynamically linked (uses shared libs), stripped

where as
file /usr/bin/diff
/usr/bin/diff: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), stripped

Where can I get the correct version of dialog.

uname -a gives :-
2.6.18-371.el5 #1 SMP Thu Sep 5 21:20:46 EDT 2013 i686 i686 i386 GNU/Linux

I am running xubuntu 11.10, fully updated, on an Acer 250 netbook (1GB ram, 1.8 GHz clock, single core Atom processor, if you can believe it). Runs pretty well, I think. So much so that I have decided to migrate from Windows to Linux.

My first question to the forum is this: I have set the Thunar file explorer to show hidden files. However, hidden files still don't show up on various File Open or Browse... dialogs.

How can I set up xfce or xubuntu to always display .hiddenfiles in Open... or Browse... dialogs?

Problem comes up when I want to edit some .config file or run the alacarte Main Menu editor and have to specify some long path to an executable in a hidden directory (as in wine). I have to enter the file name manually, which gets to be a problem for my thumb-fingered typing.

Hi,

I installed ghostscript via yum package manager. Later I wanted a newer version of ghostscript and compiled it from source. "make install" placed the gs executable file under /usr/local/bin/gs. This works if I run the command with absolute path, but if try to run gs, the shell will output

"-bash: /usr/bin/gs: No such file or directory"

if I echo the path variable it will display

/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin

If i run whereis it will give me the correct path
gs: /usr/local/bin/gs

How do I make it work so that typing "gs" will run the executable file from the /usr/local/bin/gs?

(I am using Centos 6)

Thanks.
