ARM FAQ

All Systems

• How do I compile for a specific architecture? Like ARM V6?
• How do I compile for a specific CPU?
• How do I get the compiler to generate VFP instructions?
• How do I get the compiler to generate Thumb-2 instructions?
• How do I get the compiler to generate NEON instructions?
• How do I assemble assembly that is intended for armas?
• How do I see the linker script used by the GNU Linker?
• What is the ABI for the ARM Architecture? Is it the same as the ARM EABI?
• Is it possible to link libraries created with ARM's proprietary tools (ADS, RVCT, and RVDS) with object files created by the GNU Toolchain?
• If all of CodeSourcery's GNU Toolchains use the ARM EABI, and compilers using the ARM EABI are interoperable, why are there different toolchains for GNU/Linux, SymbianOS, and bare metal?
• What is RDI?
• How do I use an RDI device with GDB?
• The Start Menu doesn't provide a way to invoke the compiler. How do I use it?
• Do I need to install Cygwin to use Sourcery G++ on Windows? If I do have Cygwin installed, does Sourcery G++ understand Cygwin pathnames?
• Will all of the changes in the CodeSourcery GNU Toolchain be merged into the official Free Software Foundation sources?
• How do I run Sourcery G++ on an x86 64-bit Linux host system?
• Why are the executable files in my new toolchain zero bytes in size?
• The installer pops up a dialog box requesting selection of a folder in which to unpack files. I have selected a folder on a drive with available space, but the installer keeps showing me the dialog box. What should I do?
• When I try to link code built with RealView® with code built with Sourcery G++, I get an error about wchar_t. What should I do?

GNU/Linux

• How do I use Sourcery G++ to build the Linux (or uClinux) kernel on Windows?
• What versions of the ARM Linux kernel can I use to run applications compiled against the Sourcery G++ (4.1 or later) binary version of GLIBC?
• Why are there no libraries for big-endian GNU/Linux? Or for systems with VFP?
• Is it possible to run both EABI and non-EABI binaries on the same system?
• Why is the configuration name for GNU/Linux arm-none-linux-gnueabi instead of just arm-none-linux-eabi? Is there a GNU variant of the EABI?
• Is the ARM GNU/Linux ABI documented?
• Why do I get "Not found" or libc.so.6 errors when trying to run applications on my target system?
• How do I install CodeSourcery's versions of the run-time libraries on my target system?
• Why does CodeSourcery provide GLIBC? Can I use the version that comes with my GNU/Linux distribution?
• Do runtime libraries shipped with Sourcery G++ include debugging information, or are they stripped? What do I have to do to be able to debug library code?

uClinux

• How do I use Sourcery G++ to build the Linux (or uClinux) kernel on Windows?
• Do runtime libraries shipped with Sourcery G++ include debugging information, or are they stripped? What do I have to do to be able to debug library code?

ELF

• Do runtime libraries shipped with Sourcery G++ include debugging information, or are they stripped? What do I have to do to be able to debug library code?

EABI

• Do runtime libraries shipped with Sourcery G++ include debugging information, or are they stripped? What do I have to do to be able to debug library code?

SymbianOS

• I get link errors when trying to create SymbianOS executables. What's wrong?
• Why does readelf issue warnings saying that a virtual address is not in any PT_LOAD segment?
