cannot execute binary file error that I scpd to a different computer

Question

I scp'd a Unix executable file into my work computer and am receiving an error when trying to run it. If I type in:

./cmpDNA 4 5 0.3 > results/results4_5_0.3.txt &

where cmpDNA is my program, 4 5 0.3 are input parameters and results/results4_5_0.3.txt is my output file, this is the error I receive:

-bash: ./cmpDNA: cannot execute binary file

I compiled in on my OS X computer using g++ and made sure to include my -m32 for a 32 bit build as the target computer is 32-bit Ubuntu. Typing:

file cmpDNA

gets:

cmpDNA: Mach-O executable i386

So I'm not sure why it won't execute. I've been looking for awhile but I can't find any answers that solve my problem. All users have executable permissions as well. Here were all of my compile options if that helps:

g++ -Wall -std=gnu++0x -o cmpDNA -m32 files.cpp

Thanks!

Can not compile on OS X without using a cross compiler and run on Ubuntu. Here is the answer that I found: Compiling C Program on OS X to Run on Ubuntu
