I'm writing a little equation solver for an exam ... it has not to be perfect or mathematically rigorous. With this program I have only to show to my professor that I can write some simple program in Assembly and C++ language. In other words, I have only to show if I have understood the basis of Assembly language. I'm referring to x86 Assembly Language.
Here's the source code: there are some c++ classes and assembly functions:
(I cannot post all the source code because it's too long for the posting form, I'm uploading it to my dropbox folder, please download it).
It's obvious that this source cod isn't complete (I'm going to finish it during the next days) but it should compile. It doesn't. I'm under linux (ubuntu) and I'm trying to compile it using these commands:
g++ -c -o equa_s.o equa.s -g3 -m32
g++ -c -o rad.o rad.cpp -g3 -m32
g++ -c -o equa_c.o class_razionali_debug.cpp -g3 -m32
g++ -o equa.out equa_s.o equa_c.o rad.o -g3 -m32
But when I try to link all the object files I get this error message:
equa_s.o: In function `second_grade_comp_solver':
/home/gianx80/Documenti/equa.s:81: undefined reference to `rad'
So, how can I compile my program without errors?
