I usually write:
'#define N 1000000
vector adj[N];
But when I run it locally, I get segmentation fault due to stack size being too small, so I end up reducing N to something like 10000 and forget to change it back again before submitting, causing unnecessary penalties.
So is there anyway to permanently increase stack size in ubuntu?
g++ -Wl,--stack=268435456 file.cpp works in Windows.
ulimit -s unlimited only increases stack size for the specific terminal
UPD:
Thanks a lot for your replies, I ended up spilling water on my laptop :(
I'll try the suggestions when (if?) My laptop gets dried.
Add
ulimit -s unlimitedto.bashrc?Thanks, but that works only if I run through a terminal. Is there any way to make it persistent even when running through sublime text?
Here is the build file I am using for
Sublime Text Build 3176onUbuntu 18.04.1 LTS.You just have to add
ulimit -s unlimited;toRuncommand.you can try
.profile. As far as I remember it is sourced during graphical login too.you can do that from code (with smth like this)
Why not modify the
/etc/security/limits.conffile? A line likeshould set your (soft) stack limit for all your processes to 1 GB by default. (The change might require a log-out/log-in in order to take effect.) For more info, please refer to
man limits.conf.Why modify such things globally?
As for me, I am using Geany, and wrote something like
for running programs.
The first part sets the stack size, the seconds one sets the memory limit (to prevent memory from exhausting because of some bugs), the last one allows to see the total time.
This worked perfectly!
brother, what can I do to run 10^10 operation? I am using Geany also.
Get a supercomputer.
wait for 100 second.
i think it's a problem for memory limit
How can i add this --stack,268435456 in vim compilation flag in linux !?
You cannot, since this linker flag is Windows only. AFAIK the stack size on Linux is known only when the program starts to execute.
