Problem after compilation

jsilvazu · October 21, 2010, 6:00pm

Hi, my name is John

I’ve been working with Matlab, and at this moment everything works good, but after the compilation with gcc, it doesn’t spear problems and when I eject the executable this massage is showed:

Error processing External Mode command line arguments:
Memory fault

the executable file is big, about 129M.

What can be the solution or, what I can do for fix it.

thanks

It means there is a bug in the program… There can be lots of causes for this and you’ve given very little information, I wouldn’t know where to begin

Hi

I installed QNX in a usb, so i have a build file, and i mounted in it gcc, and it works fine.

but I put some libraries of Matlab on qnx for create the executable file, I use the makefile for compilation, and during the compilation, doesn,t show any message, just appear the message of problem when I execute the executable.

this is my build file, I don’t know if a need modify memory parameters.

thanks

Include the current “libc.so”. It will be created as a real file using

its internal “SONAME”, with “libc.so” being a symlink to it. The symlink

will point to the last “libc.so.*” so if an earlier libc is needed

(e.g. libc.so.1) add it before the this line.

libc.so
libc.so.3
libm.so

These programs only need to be run once from the boot image.

“data=uip” will waste less memory as the ram from the boot

image will be used directly without making a copy of the data

(i.e. as the default “data=cpy” does). When they have been

run once, they will be unlinked from /proc/boot.

to release the memory back to the system. They are only

needed during boot. If needed later on, they will be loaded

from the boot device.
