I have been using gcc to compile C programs.
I want to know what exactly is the meaning of Compiling a C program.
I checked
cc -S prog.c
will give an .S file and if you analyze the hexdump I saw some assembly instructions.
So what does the compiler do which is not required in case of interpreted languages?
How can I compile a C++ application using g++ with x86 platform settings on a x86_64 machine ? What are the possible negative side-effects of compiling a C++ application with x86 settings on a x86_64 platform ?

View 1 Replies View RelatedI've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?

I'm sometimes compiling a piece of software on my Fedora 13 machine and then transferring it to an Ubuntu box. Recently I noticed this would yield issues with Fedora's .so files:
Given I had a program's binary and an .so file the program would attempt to load, both compiled on Fedora, the program would run fine on Ubuntu 8.04 LTS but would be unable to load to open the Fedora .so with an "ELF file OS ABI invalid" error.
Now any program I natively compile on Ubuntu which I run on Fedora instead, will throw the *same* error with Fedora .so's - so basically neither a Fedora bin on Ubuntu, nor an Ubuntu bin on Fedora can load the Fedora .so files, only a Fedora bin natively on Fedora can.
That means Fedora .so files are always a problem on Ubuntu, and Ubuntu bins are always a problem on Fedora (unable to load system libs there).
This is a bit odd for e.g. binary redistributions of programs (which are rare I know) and I also found out that e.g. Tibia's linux client suffers from this issue (throws "ELF file OS ABI invalid" on my Fedora 13 when attempting to load my system's libGl).
And I started to wonder whether the only way to work-around to get something that works on all platforms is a Fedora binary shipped with .so files compiled on Ubuntu - which seems a bit stupid and ridiculously complicated just to get something that works flawlessly everywhere. Isn't there e.g. a gcc switch that will allow me to compile the .so files on Fedora in such a way that they can also be used on an Ubuntu system so just compiling everything on Fedora, yet getting it to work on Ubuntu aswell would be possible?

I decided I was going to compile XChat from source today for "fun." What I ended up doing was spending a few hours getting it to compile, then find out everything didn't work the way I thought it did. I was under the impression that after I ran "sudo make install" I was "upgrading", when in reality I'm just installing a seperate version alongside the old one. Apparently I have to keep the old version so every program that was compiled with it will continue to work, so how do I:
1) Force a program to use a specific version of GTK when compiling.
2) Find where my version of GTK installed to.
I've asked some people and I've just been told to "learn LD_PRELOAD". I've googled and can't figure how I could even apply that to my current problem
