Programming :: Cmake: Using Find_package(Boost) When FindBoost.cmake Is Not In The Default Location?

Feb 23, 2010

I am attempting to compile some code on a cluster where I do not have root access (and is missing many of the libraries I want), and hence have had to create local builds of the boost and opencv libraries (i.e. in /home/username/usr/local). In particular, my cmake depends on:



which my normal development machine finds in:



On the cluster I have a version of FindBoost.cmake at:



How can I tell CMake to look for FindBoost.cmake in that directory, since neither the cmake file, nor the boost install is in the standard location? I've modified the FindBoost.cmake file to make it search in the locally installed boost libraries.

Programming :: C Header Files And Object Files ?

Sep 18, 2010

When is it good to use separate translation units and object files and link them into the main C program, and when is it good to include the header files in the main C program? I don't understand if most people include header files or if most people just link in object files and use their contents in the main program. It's sort of a simple question, but it's confusing to me and that's why I need help with it. I sort of don't understand the difference, or if there's really no difference other than the way the final result is achieved, which way is better or preferred, etc...

For example:




Simple explanation of the difference? or which one is preferred or better? I've read a little on the ELF format... so is there no difference in the end result? It's just a matter of preference or necessity, and where the information is to begin with?

Programming :: Cannot Find Header Files To Use Kmalloc()

Jun 16, 2010

I want to use kmalloc() to allocate contiguous memory on ram. But I can not seem to find the required header file(s) like linux/slab.h. I suppose I do not have the required library and I certainly do not know what and where to look.

Programming :: How To Attach New C Header Files And Libraries

Mar 10, 2010

I have been a predominant Windows user for a long time but shifted to Ubuntu recently. I was just trying out a few basic C functions when i realized that the "conio.h" header file isn't included in the libraries and therefore i was unable to use the "clrscr()" function.

I downloaded a tarball which contained the necessary library and header files including conio.h. Once extracted, i specified the location and included in the program as " #include "path to the header file" ".

I still didn't call the "clrscr()" function, and it compiled successfully. Next i edited the program to call that function and it gave the following error...

How i can add new libraries in the future?

Programming :: Put Header Files For A Shared Library?

Feb 26, 2010

I have written a simple library and ended up with a .so file. I have a header file from writing the code that describes how to use the functions in the source code I have written. I think this .h files needs to be available to other programs that access this code.

I have seen lots of tutorials on how to copy the .so file to the relevant directories and make links with the version number. What I can't find is where to put the header file so that any programs I write to use my new library can access the header.

Hope this makes sense. For example, I might use <stdio.h> normally, I will need to access <mylibrary.h> once is loaded (as far as I understand!)

It's weird, I've been using C compilers for embedded processors over ten years now and never given a second thought to how libraries and headers work behind the scenes!

Programming :: Copy Files To Dynamic Directories?

Feb 14, 2011

I have been searching for a solution to the following problem:

When my distro of choice updates Firefox web browser, the directory name is '/usr/lib/firefox-<version>'.
The problem here is that the directory name is dynamic by nature and doesn't allow a simple static solution, e.g.
'cp -rf /usr/local/files/bookmarks.html /usr/lib/firefox/defaults/profile'.

The same quandary applies when adding extensions, changing prefs etc.
I have looked at the following commands:-
find, sed, xargs, grep, awk, fprint.
Unfortunately my grasp of syntax and programming is very simple at best.

Programming :: Make List Of Directories Which Contain Files Other Than Subdirs?

Oct 17, 2009

I need to, through a bash script, go through a given directory (given as argument 1) to list out the relative path in this directory (including $1) for eact subdirectory which contains files. Directories which only contain . .. and eventually only subdirectories SHALL NOT be listed. It is this last requirement that makes it difficult for me.

I have been using the tree command for now, but I have not found a way to ignore paths to directories which only contains other subdirs or nothing at all in any easy way. I may offcourse test each directory after they are listed but this gives an extra loop to go through and I beleive it should be possible to do it directly when creatring the list. I guess by using find or ls in conjuntion with the tree command or by itself it should be possible but I am not to conversant of nested script commands.

Programming :: Moving Files To Directories Based On Part Of Filename?

Jul 6, 2010

I have a single directory of pairs of files, with the pairs sharing a string as the beginning of the filename:


I need to create a subdirectory for each pair then move the pair into the subdirectory.

I accomplished the first step using:

$find /foo -name '*T3*' -exec mkdir '{}.wrk' ;

I can use a regex to designate the pair and associate the directory, but how do I use regex in a path as the output of a move command?

Programming :: Building One KDE Component With CMake?

Jun 21, 2011

Overnight, I upgraded from KDE 4.5.1 to 4.6.3 and had a rude awakening this morning when I found that KDE had managed to, once again, break the Task Manager "force rows" behavior which had been fixed a few major releases ago. I found this lovely patch that had been applied:


And thus broken the functionality, and I want to recompile that particular plasmoid with the patch removed. However, I am completely unfamiliar with CMake or building anything at all, for that matter. All my programming is done in PHP which means I'm pretty much completely lost. I'm in the midst of pulling down the kde-workspace tree with git, and already downloaded and modified a separate copy of the file in question to look the way it is supposed to. I don't want to rebuild all of KDE, just the one module.

I have tried removing g++ and all related packages, deleting the header files folder and reinstalling, but it reinstalls the broken files. Any way of restoring the originals without reinstalling ubuntu?

Ubuntu :: Get Files/bookmarks/ - Higher Power Consumption

Jul 5, 2011

What my situation was before the problems:

-I dualboot win(xp) and xubuntu(11.04)
-No problems whatsoever except for the fact that power consumption was higher on xubuntu.

Then i read something that said that the kernel i was using was effectively having power issues and that it could be fixed so in went into the terminal and nano'd the grub config file and update-grub'd with the addition i had read all over the internet. When i rebooted it seemingly had worked but once i opened a ..... video it didn't react to anything (i'm 99% sure kernel panic since there was no hdd movement). So i forced it to shutdown and when i got back in again i nano'd the file again but for some reason i didn't only remove the power stuff but I also removed the quiet splash. Once i had rebooted it would suddenly ask for username and password twice.

once the older looking menu an then the newer looking one with the fancy bg). The first time i got in okay but afterwards i could only get in as root. I thought i had simply forgotten my password but i ran passwd myusername as root and it didn't work(only when i typed something random it gave the wrong password message). As root i also can't edit the users and groups(when i open it it stays grayed out). how do i fix this. If i will lose my account anyways then how do i get my files/bookmarks/... of of it.

Fedora :: Vmware And C Header Files ?

Dec 28, 2009

I've installed Fedora 12 (KDE version) on VMware workstation running under Windows 7.

I've been able to configure the VMware tools fine up until this point:


What is the location of the directory of C header files that match your running kernel? After some searching online I deduced I should install all of the latest updates and kernel-devel.

I then nuked the previous VMware tools install and started over with it again, but alas, no directory I try works (i.e. /usr/src/kernels/, /usr/src/kernels/ and so forth).
