How can I increase the stack-size when I want to compile ifort files on Mac OSX

[nalgenbottle]

When I execute, on the terminal I got the message of "Segmentation fault."

This message starts appearing after I increase the size of array in my code.

Looks like there is a specific size of variables we can allocate, and if we allocate more than this size, "Segmentation fault" message comes.

So I think I can solve this problem by increasing the stack-size.

Probably this question should not be posted here, could anybody please let me know how I can increase the stack size on Mac OSX?

I found several similar threads here and other sites, but they were not helpful for me.

So if anybody could explain the detail very much (like explain to a child), I appreciate it.

maybe this has the answer you are looking for?

How to increase the stack size on Mac OS X

[roddur]

'ulimit -s' is the unix command to show the maximum stack size.
'ulimit -s unlimited' will put your stack size to unlimited.

hope this will help you.

the article pointed to earlier (PDF) is a good one.

Here is a simplified article, but remember -heap-arrays (using this you may not need additional stack). Look for the linker switch for Mac OS X.

thank you all.

I understand how I can compile one single file with a larger stack size.

But what I want to do is compiling several files together and making a one executable file.

I made "Makefile" to do so, but still I do not know how I can compile them with a larger size.

Probably I should have said this first, but could anybody tell me how I can compile several files in "Makefile" with a larger stack size together?

For instance, I use this make file for one of my codes. You can choose two compilers and has diferent flags for debugging or production. If you can't figure it out maybe you could post your makefile so we can help?
