I've changed VM options in ~/.WebStorm2016.3/webstorm.exe.vmoptions through Help -> Edit custom VM options menu to the following:
# custom WebStorm VM options
-server
-Xms740m <----------------
-Xmx3050m <----------------
-XX:ReservedCodeCacheSize=240m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
After that, WebStorm is not launching. Why?
After that, WebStorm is not launching. Why?
That's because Java (JVM?) is unable to allocate that much memory (3GB; which needs to be done in 1 solid chunk .. that's is very problematic when using 32-bit JDK).
Better switch to using 64-bit JDK and 64-bit WebStorm launcher which can handle such situations if you need that much memory.
If you need more info on that -- please check this StackOverflow question and those that offered in Related section: Java 32bit Xmx vs java 64bit Xmx .
Other links to the actual JetBrains' articles on this/related subject:

https://intellij-support.jetbrains.com/hc/en-us/articles/206544869-Configuring-JVM-options-and-platform-properties
If you do not know how to start using 64-bit WebStorm, please check this arcticle or just use 2017.1 EAP build -- from 2017.1 JetBrains IDEs come with and use own 64-bit JDK by default.
If anything -- check idea.log for details (or Help | About) -- it should have bit info there.
Alternatively:

Search for Switch IDE boot JDK... action (typing just jdk should be enough to have that action preselected) and run that action

I am using
Eclipse IDE for C/C++ Developers
Version: 2018-09 (4.9.0)
Build id: 20180917-1800
under Win 10 with Portable Msys2, and gcc 8.3.0.
When launching a debug configuration in CDT, I am getting message
Error in final launch sequence: Command '-file-exec-and-symbols myprog.exe' is timed out
Session is terminated
Reason: Commnd '-gdb-exit' is timed out
Note: I only get this error while trying to debug one project.
All my other debug configurations for other projects run with no problem.
I have copied one of these working debug configurations and changed only the project name and executable into the problematic one, and I still get the error.
One possible solution I found is (here and here) downgrading component
C/C++ GDB Hardware Debugging (Help -> About Eclipse IDE -> Installation Details -> C/C++ GDB Hardware Debugging)
from 9.4.0.201712051550 to 9.3.2.201709131603.
I have
Version 9.5.3.201809121146 org.eclipse.cdt.debug.gdbjtag.feature.group Eclipse CDT.
Perhaps in my case downgarding to that old version would work too.
Prior to messing up with the downgrading, I meant to try another option (here and here):
In the debug configuration of the project, in the debugger tab, uncheck
“Reset and Delay (seconds)” and
“Halt”.
(more details here)
But I couldn't find these settings in the Debugger tab, and I do not have the Startup tab under either the Debug configuration for my project or GDB Hardware Debugging, as shown here or here.
See image.
Where can I find these settings?
Are there any other alternatives to try solving the issue, other than these two? (lest reinstalling, e.g.)
I am looking for something that allows me to debug my project, so far I cannot.

I wonder if there is a support for C++ in Netbeans 9. This link shows C++ on screenshot (when creating new project). However, after installing, I don't have one.
I wonder if there is a support for C++ in NetBeans 9.
The answer to that is definitely no, and definitely yes...
No, in the sense that the use of C++ on NetBeans 9 is not currently supported by Apache, and it is done at your own risk. NetBeans is currently being handed over from Oracle to Apache, and they haven't got to the C/C++ part yet. See What's Happened to My Favorite NetBeans Plugins? for more information.
Yes, in the sense that it is technically feasible to do it; the NetBeans 9 IDE allows you to use C/C++.
This is what you need to do:
Step 1 of 2: Make C/C++ available as a plugin.
Tools > Plugins > Settings tab > click the Add button.
On the Update Center Customizer screen:
Enter some value in the Name field (e.g. "My plugins"),
Enter http://updates.netbeans.org/netbeans/updates/8.2/uc/final/distribution/catalog.xml.gz in the URL field
Click the OK button.
This should create a new entry in the Configuration of Update Centers list in the Settings tab.
Checking that new entry should instantly add plugins to the Available Plugins tab.
Click the Available Plugins tab, then click the Category column to sort the entries by category.
The Name of the entry at the top of the list should be C/C++. If so, you have successfully made the plugin available:
Step 2 of 2: Install the C/C++ plugin.
Check the C/C++ entry shown in the screen shot above, and then click the Install button.
Follow the wizard's instructions. The plugin will be downloaded and installed, and you will be required to restart NetBeans.
To confirm that C/C++ has been installed, click Tools > Plugins > **Installed tab. You should see an entry for the C/C++ plugin you just installed.
Also, verify that you can now create a C/C++ project through the Project wizard:
Notes:
The finer details on configuring C/C++ on NetBeans 9 (Tools > Options > C/C++) are unchanged from NetBeans 8.x. Refer to Configuring NetBeans IDE 8.0 for C/C++/Fortran for that.
Much of this answer has been copied from an answer I gave on problems with Tomcat on NetBeans 9, but the details are sufficiently different to merit a separate answer.
Netbeans 10 and 11 - adding C / C++ also works in the same fashion.
In Netbeans go to Tools->Plugins->Settings
Entry NetBeans 8.2 Plugin Portal is already present.
Click the checkbox next to this entry.
Switch to Available Plugins tab, click Check for Newest.
C / C++ is now on the list.
Computer that this is done is on Windows 10 x64.
You have to install C++ plugin (Tools -> Plugins)
I'm tasked with hooking up Google Test in Eclipse. I got Google Test working from the command-line, but we want it working like JUnit for Java in Eclipse. This is theoretically possible. However, running through all the online instructions I can find, they all say to use Run -> Run Configurations... -> C/C++ Unit option. For the life of me, I can't find it. Everything else is in the Run Configurations dialog, just not that item.
So I figured, even though we have Eclipse for C++ Developers installed (which should contain everything that the CDT Plug-in contains), maybe it's missing the unit testing stuff. Trying to update CDT, however, just shows that the only thing missing is the Autotools stuff (which we have no need for).
Vital statistics:
Eclipse version: Oxygen.1a Release (4.7.1a)
Operating System: Linux, CentOS
Compiler: gcc
I know that's the not the latest version of Oxygen. It's the latest we can use, because the current versions have a bug that doesn't recognize our code as valid C++.
How do I get the C/C++ Unit option in Run Configurations?
You need to install "C/C++ unit testing support" feature. Go to Help -> Install new software, select All available sites and search for it. Installing it will require Eclipse restart. After restart C++ unit test group will appear in the list of Debug configurations.
I cloned LEDE repository from github and wanted to debug my simple program on router. To do this, I configured LEDE build (like here: https://wiki.openwrt.org/doc/devel/gdb) using menuconfig:
Advanced configuration options (for developers) → Toolchain Options → Build gdb
Development → gdbserver
Development → gdb
Then I compiled my simple program with -ggdb3 flag and wanted to start debugging. However, it is impossible because gdbserver binary seems to be missing on router after sysupgrade (it does not appear in /bin, /sbin, /usr/bin, /usr/sbin). Have I missed something in this configuration?
OK, I figured it out. When you build the system image and total package size is bigger than your available ROM (in my case 4MB), your .bin in /bin/targets/ directory won't be updated and you will get your old image. Everything without any warning message!
We're using the Eclipse CDT 5 C++ IDE on Windows to develop a C++ application on a remote AIX host.
Eclipse CDT has the ability to perform remote debugging using gdbserver. Unfortunately, gdbserver is not supported on AIX.
Is anyone familiar with a way to debug remotely using Eclipse CDT without gdbserver? Perhaps using an SSH shell connection to gdb?
finally I got gdb run remotly anyhow now. At the Bug-symbol on the taskbar I took Debug Configurations - GDB Hardware Debugging.
In Main C/C++ Applications I set the full path on the Samba share of the executable (X:\abin\vlmi9506). I also set a linked folder on X:\abin in the project. Then I modified my batch-script in GDB Setup. It's not directly calling gdb in the plink-session but a unix-shell-script, which opens gdb. By this I have the possibility to set some unix environment-variables for the program before doing debug. The call in my batch:
plink.exe prevoax1 -l suttera -pw XXXXX -i /proj/user/dev/suttera/vl/9506/test/vlmi9506ddd.run 20155 dev o m
In the unix script I started gdb with the command line params from eclipse, that I found in my former tryals. The call in the shell command looks like this:
gdb -nw -i mi -cd=$LVarPathExec $LVarPathExec/vlmi9506
Then IBM just gives gdb 6.0 for AIX. I found version 6.8 in the net at http://www.perzl.org/aix/index.php?n=Main.Gdb. Our Admin installed it.
I can now step through the program and watch variables. I even can write gdb-commands directly in the console-view. yabadabadooooooo
Hope that helps to others as well. Can not tell, what was really the winner-action.
But each answer gives more new questions. Now I got 3 of them.
When I start the debug config I have to click restart in the toolbar to come really in the main procedure. Is it possible to come directly in main without restarting?
On AIX our programs are first preprocessed for embedded sql. The preprocessed c-source is put in another directory. When I duble-click the line to set a breakpoint, I get the warning "unresolved breakpoint" and in the gdb-console I see, that the break is set to the preprocessed source which is wrong. Is it possible to set the breakpoints on the right source?
We are using CICS on AIX. With the xldb-Debugger and the CDCN-command of CICS we manage that debugging is started, when we come in our programs. Is it possible to get that remotely (in plink) with gdb-eclipse as well?
I wouldn't normally take a shot in the dark on a question I can't really test the answer to, but since this one has sat around for a day, I'll give it a shot. It seems from looking at:
http://wiki.eclipse.org/TM_and_RSE_FAQ#How_can_I_do_Remote_Debugging_with_CDT.3F
...that even if the CDT has changed since that wiki page was made, you should still be able to change the debug command to:
ssh remotehost gdb
instead of using TM which uses gdbserver. This will probably be slightly slower than the TM remote debugging since that actually uses a local gdb, but on the other hand this way you won't have to NFS or SMB mount your source code to make it available to the local debugger (and if you're on a LAN it probably won't matter anyhow).
There's also a reference TCF implementation for linux, which you may or may not have any luck recompiling for AIX, but it allows for remote debugging if gdbserver is otherwise not available:
http://wiki.eclipse.org/DSDP/TM/TCF_FAQ
tried also to remotly debug an aix-appl with windows eclipse-cdt-gdb.
Got blocked at the end with unix/windows path-problems. Maybe my result can help u a little further - maybe you already got it work. I'm interested in your comment. asked on eclipse news portal- following the answer of martin oberhuber (thanks again) tried dsp dd (also blocked with path problem) and set an request in eclipse bugzilla.
here the link to news:

Here my bugzilla:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252758
At the moment we still debug localy with xldb but I am trying ddd-gdb at the moment. At least locally gdb is running.
