How do you cross compile glibc for arm?

2 Answers

1. Use a precompiled toolchain, like those provided by code sourcery.
2. If you want to make your own, optimised (premature optimization is the root of all evil), use crosstool-NG, which is a tool dedicated to cross-compilation toolchain building.

How do you make a cross compile?

To build a cross-compiler, you need a working C compiler (gcc is generally a good idea). A C compiler is supplied with most Linux /UNIX-based operating systems. You also need the source code for the various tools used to build the cross-compiler. You can download GNU tools from GNU (http://www.gnu.org) .

What is cross compiling Linux?

To “cross compile” is to compile source on say a Linux box with intent on running it on a MAC or Windows box. This is usually done using a cross compilation plugin, which are readily available from various web servers across the net.

Why is GCC a cross compiler?

Explanation: GCC, a free software collection of compilers, also can be used as cross compile. It supports many languages and platforms. 6.

Can gcc compile for arm?

For example, if you need to compile C code for ARM, you must first install gcc-arm-linux-gnu (32-bit) or gcc-aarch64-linux-gnu (64-bit) on Fedora or RHEL, or arm-linux-gnueabi-gcc and binutils-arm-linux-gnueabi on Ubuntu. This provides the commands and libraries you need to build (at least) a simple C program.

How do I configure glibc?

2. How to build

2. 2.2. Configure. % cd ..
3. 2.3. Build glibc. % make.
4. 3.1. Install glibc. % make install.
5. 3.2. Install the dynamic loader into the “/trusted” directory. % mkdir -p /trusted/local/lib/glibc-testing/lib.

How do I create a GCC cross-compiler in Linux?

Building GCC cross compilers from scratch

1. build and install binutils.
2. copy and install kernel headers.
3. build and install stage1 gcc (this one cannot compile userland programs, but is good enough for the kernel or bootloaders)
4. build and install cross-glibc.
5. build and install final gcc. $ export TARGET=aarch64.

What is cross-compiling in Linux?

Cross-compilation is the act of compiling code for one computer system (often known as the target) on a different system, called the host. It’s a very useful technique, for instance when the target system is too small to host the compiler and all relevant files.

What is the purpose of cross-compiling?

The fundamental use of a cross compiler is to separate the build environment from target environment. This is useful in several situations: Embedded computers where a device has extremely limited resources.
