Player-Stage uses .cc files. I know how to compile them. But how do I actually execute my code? There is an output file generated. There is nothing in the .cfg file or in the .world file that specifies what program to use to run the robot. Or is it not specified in the world or cfg files?
Then how to make the robot obey my compiled .cc file? If this question is silly or if I am asking stupid questions
I am trying to create a RS232 C program that executes a series of commands down the line to a robot. Everything seems to work fine, except any sequential write to the serial port. At first I thought it was the UART's buffer being filled too fast, but even with a 50 uS delay it still throws the error.
Here is my code:
Code:
#include <termios.h>
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/signal.h>
#include <sys/types.h>

I need to modify fs/open.c and fs/read_write.c to make my modifications. I cannot find any options in 'make menuconfig' to make these files modules rather than compiled elements. I'm thinking these cannot be modules because the file system won't work without open.c and read_write.c. Is this correct - I cannot compile fs/open.c and fs/read_write.c as modules, only as compiled elements? Or, is there some way for a module to overwrite these routines when the module is installed and re-enable the routines when the module is removed?

However this causes lots of problems (folders have extensions, I have duplicate folders, the names with spaces create a folder for each element of the name).
The contents of the folder is basically movies (some with subtitles). Some of the names have things like (original) or CD1 CD2 in them.
How come the program is compiled without errors but I can't run it?After writing

I've compiled some code which I've given to other people, however when they try to run it they get segemtation fault. After some testing I've found if it's ran from root (where I compiled it) everything works, if I try to run from a user there's a fault.

I am debugging a project and I noticed the .so files from my installed version of this project are being used when I run the main executable. However what I want is that the modified and compiled libraries (.so files) are being used. This is for testing the software. So I don't want to install these. I tried adding the directory with the .so files in /etc/ld.so.conf and doing ldconfig. However that did not seem to work. How can I let the main executable use the modified .so? I also want to debug this using gdb, so if someone knows what I should do to get those modified .so files being used for execution.

I have an script called conection located in /etc/ppp ( /etc/ppp/conection)The content of the scrips is:
pppd call isp Running it by hand, it dials out to my ISP and fetch all my email from different accounts and turn-off the link. It works great. I decided to automate the process using the cron.
The problem is when cron execute it at the specified time, nothing happens. It doesn't even dials out. I checked /var/log/cron and cron says It was executed. But it doesn't. I try again running the script by hand and works fine.
Is it possible to make an AWK script that goes over the file multiple times, every time doing something different to it?
View 19 Replies View RelatedI have a bit of a problem and the only solution I can think of at the moment is a very tedious one, so I was hoping there would be a better way. What I am trying to do is cross compile the PPPD program so that I can install it on an embedded system (this system does not have make/gcc on it). It was easy to cross compile it, but I can not run "make install" since I'm compiling on a secondary machine. I don't want to install PPPD on this secondary machine (I couldn't anyway, because it was compiled for a different architecture) and I can't run make install on the target machine because there is no make/build system for it.
So it seems like what I would have to do is to manually copy over each compiled file from the build machine to the appropriate location of the target machine. And the only way (that I know of) to figure out how to do this is to manually examine the Makefiles (yes, there are several for PPPD) and figure out which file should go where on the target system. This isn't trivial because it uses a hierarchy of makefiles and the probability of human error for this method is high.
Is it possible that I could run another command that would give me a list of all the commands that make install would perform? Or a list of all files and their target location for "make install"? Or possibly some other solution that I am completely unaware of that would make this task not so painful and error prone?
I am trying to compile a C++ source file into a static library using make with root privileges (i.e., using "sudo"). However, I "sometimes" get the following compilation error:
Code:
g++ -Wall -g -fPIC -W -c /home/project/ether/src/packet-ethernet.cc
ar -cvq libether.a /home/project/ether/src/packet-ethernet.o
ar: /home/project/ether/src/packet-ethernet.o: No such file or directory
make: *** [libether.a] Error 1
I checked /home/project/ether/src folder to see if packet-ethernet.o in fact does not exist, and saw that it is actually located there, but its owner is "root", which is different from the current user. If I change the owner of packet_ethernet.o from root to the current user using "chown" command and execute make again with sudo, everything seems to be fine.
It may be a coincidence that I recently migrated to 64-bit platform from 32-bit, and then installed libboost-filesystem1.40-dev. After that, I began to experience such errors. I have "never" come across such a compilation error before. Even though I completely removed libboost-filesystem1.40-dev afterwards to see if it causes the problem, nothing changed.
After migrating to 64-bit and installing libboost-filesystem1.40-dev, my application exhibited another "weird" behaviour such that it produced "hidden" files using mkdir() system call, which were previously created as regular ones on the filesystem. Can compiler options that I use cause such problems? Is it possible that libboost-filesystem1.40-dev overwrote some system libraries so that I am getting such errors ?
My assessment is making a tree from a text file as follows: -reading a file line by line
-making a binary tree from it
- traverse by level the binary tree
- posting the traversal result to the same file without overwriting the text file- it is required to be append to the bottom of the text file (i have to do this in 4 languages: c#,PHP from Xampp,java, python)
i read the file with this script in java:
public class FileToStringArray {
privateString strLine;
privateString[] stringArray;

When I try to compile some Java code on Ubuntu 10.10 (kernel 2.6+) using make and a Makefile.
I get an error indicating that the make utility cannot execute the java compile command (javac).
The error reads: /bin/bash: line 6: .: /usr/local/jdk1.5.0_18/bin/javac: cannot execute binary file
I am executing make as root. I have enabled permissions on all directories in the path /usr/local/jdk1.5.0_18/bin/javac and on javac itself.
I get this error whether using a jdk installed via ubuntu apt-get, or whether I install the jdk myself. And I get it using either Java 1.5 or 1.6
My machine has an 80386 processor. I notice the make utility is built for i686-pc-linux-gnu
However, I can manually compile using javac.
I can compile calling javac from within a bash script.
I can compile using the java compiler gcj from the command line: gcj --main=HelloWorld HelloWorld.java -o HelloWorld.exe
But I cannot compile java code from the makefile. Any reasons why I might be getting this error?
