I have looked as thoroughly as I can, and I have found no solution to my issue. I'm on RHEL 8 using the C/C++ Eclipse IDE v2021-3 and while my IDE once stopped at breakpoints, it no longer does so. So my experience is that it simply runs through to completion as if a normal Run was performed, regardless of where I place my breakpoints.
Things I have tried that have not worked:
Ensuring that Skip All Breakpoints is disabled
Cleaning and rebuilding the project
Ensuring that my breakpoints are attached to code that is being executed
Ensuring that Eclipse is up to date.
Restarting Eclipse
Crying
Updating gdb
Things I have not tried:
Redownloading Eclipse, since it isn't installed on my machine, and it's freshly updated, I didn't do this
Any thoughts? Thank you in advance!
There's this bug with the placement of certain characters in the embedded terminal in CLion (the Run tab that pops up when you click the Run button), and I figured out that if I changed the terminal in CLion, that wouldn't happen. I changed the terminal to cmder, and it is all working now, except one thing: I can't figure out how to make CLion run the program to that terminal.
I tried changing the configuration, but all it did on run was open cmder but not execute the program (I had to run it manually, by writing the file name).
I wonder, what's the way to fix this, and make CLion directly run C programs on the terminal, instead of the Run tab?
Thank you.
The CLion run configuration always runs in the integreted run window. That is not a terminal emulator, and it cannot be changed so that it runs in an actual terminal emulator (like cmder).
Your best bet is to try to fix the "character placement" in the run window. Maybe ask a different question where you explain the issue, or if it's a clear bug, file a bug report for it.
I would like to make a Graphical interface for a home-made program using SFML on Raspberry Pi2. I am using Raspbian. I recompiled the graphical lib
It works fine unsing startx first, then using my application, which wors perfectly fine.
But I can't figure if it is possible or how to launch my application directly after boot without launching startx (just to optimise the cpu of the Raspberry).
Starting my program direcly after boot, I get the following error:
Failed to open X11 display: make sure the DISPLAY environnement variable is set correctly.
Aborted.
I already tested the classic export DISPLAY=:0.0 but without sucess.
I interested myself in x and xinit, but I am not sure that would even do it.
Where should I start looking? I don't need a complete solution, even a hint or an idea would be nice!
I checked to see if it was possible to open a graphical app without the X desktop environment and as that answer states, with Firefox at least, you need the X server which SFML also probably needs in order to create a window.
The answer states:
Basically something like:
$ X
Then you just start Firefox in this X server:
$ DISPLAY=:0 firefox
You can switch from the X server and the framebuffer by using
CTRL+ALT+F1 and CTRL+ALT+F7.
You could try that and see if it helps.
Also, still searching, I found a forum post on the sfml website about what you're trying to accomplish stating somewhere:
SFML requires OpenGL, so as far as I know you need at least X running,
but you probably don't need gnome, KDE or a similar Desktop
Environment on top.
The forum guy asking for help seems to have managed to get X11 and a SFML basic render window to work on Ubuntu server after someone posted a link to xinitrc. I guess, that's the route to go from here.
I recently installed CodeBlocks with mingw32 on Windows 7 Ultimate 32bit in order to dust off my c skills, but this problem has me somewhat stumped.
I decided to fire off a short Fibonacci generator to make sure my setup was working, but I ran into a hurdle.
The program compiles, links and whatnot like a charm and I get a corresponding executable which runs as expected.
The problems occur if I try to compile again, then I get the following:
c:/codeblocks/mingw/bin/../lib/gcc/mingw32/4.4.1/../../../../mingw32/bin/ld.exe: cannot open output file bin\Debug\Fibonacci.exe: Permission denied
I can't even edit the permissions of the generated executable.
I've checked the usual suspects:
Executable is verily not running.
Path to executable is read/writable to mingw32 (otherwise it wouldn't be able to build in the first place)
I'm not running cygwin in any shape or form.
And now for the funny bit: Usually after a few minutes, any executables generated by mingw32 which are displaying this Access Denied behaviour will automatically vanish without any intervention from me.
I've googled this somewhat, but most of the other results were either vague or inapplicable.
I wonder whether there is some Windows 7 security setting playing havoc with my .exe's, but I'm not that knowledgeable about Win 7 as to know where to begin searching.
Any one have any ideas?
I had exactly the same problem right after switching off some (in my opinion unneccessary) Windows services. It turned out that when I switched ON again the "Application Experience" everything resumed working fine.
May be you simply have to turn on this service? To switch ON Application Experience:
Click the Windows start buttonn.
In the box labeled "Search programs and files" type services.msc and click the search button. A new window with title "Services" opens.
Right click on "Application Experience" line and select "Properties" from popup menu.
Change Startup type to "Automatic (delayed start)".
Restart computer.
Application Experiences should prevent the problem in the future.
Your program is still running. You have to kill it by closing the command line window.
If you press control alt delete, task manager, process`s (kill the ones that match your filename).
If you think the executable is locked by a process, try Process Explorer from SysInternals. In the File/handle, enter Fibonacci.exe and you should see who holds the file.
If it is not enough, you can use Process Monitor (from SysInternals, again) to follow the activity of all processes on your system on Fibonacci.exe.
With a little bit of analysis (call stacks), you'll may find out why the access to the file is denied and what make it disappear.
Problem Cause :
The process of the current program is still running without interuption.
(This is the reason why you haven't got this issue after a restart)
The fix is simple :
Go to cmd and type the command taskkill -im process_name.exe -f
Eg:
taskkill -im demo.exe -f
here,
demo - is my program name
The Best solution is go to console in eclipse IDE and click the red button to terminate the program.
You will see the your program is running and output can be seen there. :) !!
I had the same behaviour, and fixed it by running Code::Blocks as administrator.
Open task manager -> Processes -> Click on .exe (Fibonacci.exe) -> End Process
if it doesn't work
Close eclipse IDE (or whatever IDE you use) and repeat step 1.
I had a similar problem. Using a freeware utility called Unlocker (version 1.9.2), I found that my antivirus software (Panda free) had left a hanging lock on the executable file even though it didn't detect any threat. Unlocker was able to unlock it.
Got the same issue. Read this. Disabled the antivirus software (mcaffee). Et voila
Confirmed by the antivirus log:
Blocked by Access Protection rule d:\mingw64\x86_64-w64-mingw32\bin\ld.exe d:\workspace\cpp\bar\foo.exe User-defined Rules:ctx3 Action blocked : Create
It may be your Antivirus Software.
In my case Malwarebytes was holding a handle on my program's executable:
Using Process Explorer to close the handle, or just disabling antivirus for a bit work just fine.
i experienced a similar issue. Bitdefender automatically quarantined each exe-file i created by MinGW g++. Instead of the full exe-file i found a file with a weird extension 'qzquar'
testAutoPtr1.exe.48352.gzquar
When i opened quarantined items in Bitdefender i found my exe-file quarantined there.
I got this error when using the Atom editor and mingw (through a package called gpp-compiler) for C++. Closing the open console window fixed my issue.
I am developing on a Windows machine using Eclipse in C code.
All the files are physically located on a Linux server.
I am using Eclipse only for editing and code browsing.
When I want to compile, I open a terminal and telnet to the Linux server from which I call a file that sets up few variables and eventually invoke a "make" command.
The server is pretty busy.. I would then like to be able to compile locally [and then just ftp these executable files back to the Linux machine so that I can execute them.. unless Eclipse can do that on its own :) ].... any idea how can that be done? I am not well versed in Eclipse or OS usage.... so if you could answer and explain what I should do.. I would really appreciate...
I changed the Build Command under Project Properties menu by just calling the script file on the server I usually invoke to compile... That looked fairly simple.. well... that was too good to be true... and of course.. it didn't work! I am getting this error if I use the default "make" (Cannot run program "make": Launching failed).... while getting (Cannot run program "T:\compile": Launching failed) if I try to invoke my script file that I use to compile...
thanks,
You should take a look at running a crosstool-ng setup on your windows box inside cygwin. And then have eclipse use that compiler. This will allow you to develop for your target Linux platform easily.
Here's some slides
It sounds like you're developing for a desktop/server platform, so you'll have to make sure you set up your crosstool-ng with the same versions of standard libs as your server has (libc, libstdc++, etc). You also want to make sure your crosstool-ng has the same version of gcc as the target as well.
If you don't want to mess with getting all that setup, you could always install Linux as a virtual machine on your windows box and work inside there.
