Segmenation fault – core dump error assembly 32bit code on 64bit machine
I have a shiny 64 bit dell machine that tops ubuntu on it.
I working working on some other machine a bit of assemly code and I didn’t have a problem.
But when I run the same code my 64 machine i was getting the a segmentation falut error. Not surprising actually.
here is what I have done to resolve it:
1. Don’t forget to add .code32 at the beginning of your assembly file. [ talking about x86 architecture ]
2. Have the gcc multilib on your machine
sudo apt-get install gcc-4.7-multilib
3. When assembling and linking your file use
gcc -m32 -nostartfiles -o executablename filename.s
Change your executablename and filename.s accordingly
flush memcache contents from command line
Assembly code example – square a number
wireless not working on ubuntu 12.04 on dell inspiron
SSH without password not working: mac to ubuntu
You will have to enable the component called ‘universe’
