Compilation for Applications

To compile a simple C application, use the cross compiler instead of the regular compiler:

#arm-linux-gcc –o example –Wall –g –O2 example.c

#arm-linux-strip –s example

#arm-linux-gcc -ggdb –o example-debug example.c

Most of the cross compiler tools are the same as their native compiler counterparts, but have an additional

prefix that specifies the target system. In the case of x86 environments, the prefix is i386-linux-. In the case

of the ioPAC RTU controller, the prefix is arm-linux-.

For example, the native C compiler is gcc and the cross C compiler for ARM in the ioPAC is arm-linux-gcc.

Moxa provides cross compiler tools for the following native compilers. Simply add the arm-linux- prefix.

ar Manages archives (static libraries)

as Assembler

c++, g++ C++ compiler

cpp C preprocessor

gcc C compiler

gdb Debugger

ld Linker

nm Lists symbols from object files

objcopy Copies and translates object files

objdump

Displays information about object files

ranlib Generates indexes to archives (static libraries)

readelf Displays information about ELF files

size Lists object file section sizes

strings Prints strings of printable characters from files (usually object files)

strip Removes symbols and sections from object files (usually debugging information)
