I want to do some Linux kernel programming. I have chosen Eclipse CDT as my IDE but i can't seem to get a project started. By started i mean that i can't get trough the project wizard.
I have followed different tutorials like this one:
Link to tutorial
On the select configuration screen when i press finish the program doesn't continue (there is a loading bar, but it dissapiears quickly).
Can anyone give me some pointers to solve this problem? I run Ubuntu 12.04 on a parallels virtual machine on a Macbook.
Thanks in advance!
Check if the directory containing your kernel source is owned by 'root'. I faced that problem and resolved it by doing a sudo chown -hR my_user_name my_kernel_dir. Sadly Eclipse (3.8.1) does not show any visible warning.

I've been here before and even wrote an article on how I was able to connect Coldfusion 2018 with Mac OS X Mojave, but since the upgrade to Mac OS X 10.15 Catalina, I haven't been able to get Coldfusion to work correctly on virtual hosts (ie. http://local.mylocalsite.com).
Goal: install Apache connector for Coldfusion so that I can run my dev site from within the /Sites folder like I would any other site.
Problem: Apache is working and I can access websites from the /Sites folder using the virtual host (ie. local.mydevsite.com), but although Coldfusion is running (I can access the Coldfusion Administrator), my computer does not seem to recognize that Coldfusion is supposed to run. I don't know if this is Apache or Coldfusion's responsibility.
What I've tried: I've tried using the GUI connector, as well as trying to confirm the settings via command line. I have XAMPP installed, which I believe that DesktopServer (an application by ServerPress) is relying on, but that's probably not relevant; but what I'm getting at is that I believe XAMPP relies on Mac's default installation of Apache.
I've also tried to go into every file that is referenced in any instruction document to determine if there is anything out of place. Part of my confusion is that there are many instances of some of these files and I'm not sure which one is active. Here are some of the files I've looked into:
/Applications/XAMPP/xamppfiles/etc/extra/httpd-vhosts.conf
/Applications/XAMPP/xamppfiles/apache2/conf/httpd.conf
/Applications/XAMPP/xamppfiles/apache2/conf/mod_jk.so
/private/etc/apache2/httpd.conf
/private/etc/apache2/mod_jk.conf
/private/etc/apache2/extra/httpd-vhosts.conf
From what I can tell, the main settings for Apache are stored in the /private/etc/apache2 folder, but I want the XAMPP version of https-vhosts.conf because that's where DesktopServer is pulling their virtual hosts from. Regardless, I don't think it matters which vhosts file is being used because Coldfusion won't run on any of the local sites from my /Sites folder that are loading correctly when I visit local.anylocaldevsite.com.
Thoughts? This is either a really dumb question because no one else is asking it, or there aren't many Mac users who also use Coldfusion. Would love assistance if anyone has a clue. Thanks!
Update: This isn't an exact answer, but the recommendation to try CommandBox was a win. I installed CommandBox and then ran the "ColdBox" application in the root of my project and the site opened up in my browser like a gem. Wonderful. Thank you! I can call that the "answer" if no one objects, but I know that it's more of a workaround than an exact fix.
I am developing a robot using raspberry pi 2 in java.
Up until now I was writing the code itself on my pc in InteliJ-IDEA (since its not running smoothly on the pi).
Then I am connecting to the pi with WinSCP in order to sync my project and afterwards I am using putty to compile and run the code remotely thru ssh.
I would like to compile and run the code directly from my PC (with intelij & maven) as that guy does in that video.
I searched quite some time for an answer and I couldn't find one.
I would really appreciate if someone could provide me a solution to my problem,
it will save me a lot of time, and I would be able to debug my code efficiently again.
Thanks in advance.
I found plugin which help a lot.
If you have the same issue as I had, you can download it from that link,
or install it directly from the IDE:
settings >> plugins >> browse repositories, and search for "Embedded Linux JVM Debugger".
I'm having trouble opening VMWare on my Mac pro OS 10.10. I didn't do anything, moving its files or anything. I just turned my Mac off before I went to bed last night, and then this morning, when I tried to open VMWare again on my Mac, it keeps giving me this waring:
File not found.
I'm very confused, I've important files storing on my Windows workspace and need to have it restored.
What I've tried:
I've uninstalled VMWare on my machine, and re-downloaded and reinstalled it back, but, no luck, still the same warning. VMWare doesn't open at all.
I've also restarted my machine, hoping that something magic can happen, but unexpectedly, no luck.
OK, question resolved after I went to the Tech Stop at my University.
We just found that Windows 7 was somehow gone in my VMWare, then we opened Virtual Machine Library of VMWare, then re-installed Win7 into this VMWare, as this picture shows: http://postimg.org/image/blnk4x59z/
Now things are working fine.
Some other people might run into the same issue in the future, I don't know why this happened and nobody really knows what's going on.
I called VMWare tech support, but they don't provide any help since I downloaded it for free from our CS department website. But our department tech assistance has never met this issue. So nobody to turn to.
But anyway, pretty simple to fix:
Just re-install win7 in your VMWare, if you run into the same case as I did, by opening your Virtual Machine Library.
I experienced the same symptom after rebooting my Mac. SSun's answer helped me to solve it, but I think I can offer a bit of further insight.
VMWare Fusion was actually launching successfully, but when attempting to open a machine that was open at last quit, it fails to find the machine's files. I mis-interpreted the message as meaning that VMWare couldn't find an internal file and thought it had failed to launch. I got the same error when attempting to reinstall.
SSun refers to re-installing a guest OS. To be specific, one just needs to delete the reference to the virtual machine in VMWare (after dismissing the popup and you can access to the Window menu and open your virtual machine library); not reinstalling the actual guest OS. One can then recreate the reference by opening the machine via File > Open. Alternatively, resolve the root cause of the machine not being found.
In my case the root cause was that the virtual machine resided on a different hard drive to Mac OS and was referenced via a symlink. This hard drive had failed to mount automatically at boot up.
The same confusing error occurs when reinstalling because at the end of the install, VMWare launches automatically, triggering the symptom again.
I followed the steps from kb.mit.edu below to resolve this issue:
Click OK to close the error message.
Close the Virtual Machine. Click the red dot in upper left hand
corner or execute the keyboard shortcut Command+W
Follow the menu path Window >> Virtual Machine Library to open the
Virtual Machine Library.
Right-click on the thumbnail image for the VM or hold down the Ctr
key while clicking on the thumbnail image for the VM. Result: A
drop-down menu appears.
Select Delete Result: Remove Virtual Machine dialog box appears, with
options to Cancel, Move to Track or Keep File.
Choose Keep File.
However after doing the above, I found out that you need to resart your machine for eveything to work properly, else the problem will still persist.
If you get this error – including after deleting a VM (i.e., you cannot do anything inside the VMWare Fusion app to resolve this) – I found that the following will work, without reinstalling the app, deleting its preferences, or rebooting the host Mac, but at the tiny cost of having to re-add your VMs to the list of the available ones (a simple drag-and-drop operation):
Shut down any running VMs that are functioning, then shut down VMWare Fusion.
Trash the "~/Library/Application Support/VMware Fusion/vmInventory" file
Open the Activity Monitor app, search for "vm", and shut down everything with "vmware", "vmnet", and "vmrest" in its name. (Or do effectively the same thing in the Terminal, with ps aux | grep vm and then kill -9 on each of the appropriate process numbers, if you're command-line-oriented.)
Go find your VMs in Finder.
Restart the VMWare Fusion application.
Drag each of your VM packages to VMWare and drop it on the now-empty left pane of the Virtual Machine Library window to re-add the the VM to the list.
Test-start each of them to make sure you didn't break anything. [This is the paranoia option, here.]
Restart VMWare to make darned sure it writes out new config files. [My trust level in this app is quite low of late.]
I am trying to create a dev box for SharePoint 2010 Server utilizing the following:
http://blogs.msdn.com/b/cjohnson/archive/2010/10/28/announcing-sharepoint-easy-setup-for-developers.aspx
So first of all this is new to me. I understand that these are instructions are for dual boot in Windows Native, but I am more interested in using a VHD/image of the OS to run on VMWare.
I have tried creating an image of a running virtual machine with sysprep tool, but hit a dead end with capturing the image to a file that I can reference within the running machine to run the scripts against.
I took a look at Diskpart on TechNet, but as I am new to this, I am not sure this is what I want to do?
I tried installing to the local host (virtual machine that is running) and am getting an error there also; fails at Windows Identity Framework.
It is a clean install of Windows 7 (literally nothing else), and the UAC has been disabled.
Is there any insite, help, or advice anyone can provide me regarding this? I would really appreciate it as I have to get working on the development aspects of SP (workflows, web parts,etc), and need a dev env, and I can't seem to get anywhere with this.
Thanks

I got a question of using Eclipse to develop for embedded Linux on a Windows host
Here are now I have and where I am.
1. a Windows host that have the latest Eclipse + CDT (c/c++ development tools) installed
2. a Ubuntu host (ssh + samba installed) that contains sources and toolschain to build the project. (the windows and ubuntu hosts are sitting within one network segment (In LAN).)
3. I can use the following commands to build this project under Ubuntu.
# chroot dummyroot
# cd /home/project/Build
# sh Build date +%Y%m%d%H%M%S
4. I am now trying to create an eclipse C++ project to achieve the goad of the step 3, but I have been stuck here for a while. any ideas of how it can be done?
Speaking from experience, attempting to develop embedded Linux on a Windows host is a world of pain and frustration. Emphasis on attempting -- I'd like to meet someone who completed a serious project in this way, or who can explain how working in Windows made job easier.
Windows can be a great development environment for many tasks, but it's a lousy, lousy environment for embedded Linux. There are tools out there to help you do this, but everything is much harder compared to working on a Linux host. The toolchains are older and buggier. You will constantly fight with your crosscompilers and GNU autotools trying to get packages to compile. (Wait till you try to compile one of the many packages that needs to build an intermediate binary and then executes that as part of its build process.)
You probably have reasons for keeping your desktop in Windows -- just run a Linux virtual machine.
Eclipse CDT can execute arbitrary commands, such as
ssh username#target build_script
using the external builder. If you are using gcc on the target eclipse cdt can parse the output of the gcc and make from the ssh session and send you to the correct source path (if that path matches the path generated by gcc). Although this might not work windows->linux
With Embedded Linux, I've attempted to run Virtual Machines using Ubunutu, Xubutunu, Debian. I have been developing for a long time. I design hardware and develop low level firmware, to test said hardware. I cannot get anything to work on instructions given, as in an unified IDE and development system such as I am used to (i.e. Codewarrior, MPLAB, Code Composer) If Embedded Linux is so useful and easy how is it I cannot get a single one of instructions from Yocto, Freescale, Timesys, anywhere to work? Every-time there is a directory change, or a directory that no longer exists, or even a file that is not there. Surely there something that I can use..
