Shell script to build gcc for various architectures

GCC toolchain generator script

Shell script to build plain elf gcc toolchains for various architectures

Sample run:

./doit -f -a "i386 x86_64 aarch64"

This will download sources to and build 3 toolchains, for i386, x86_64 and aarch64. The resulting output will be located in

<arch>-elf-<version>-<hostos>-<host arch>/

For example: aarch64-elf-7.1.0-Linux-x86_64/

Run ./doit with -h for help.

toolchains's Issues

Add clang/lld to the toolchains

It would be great to try the latest versions of clang/lld. Unfortunately the one shipped with Debian/Ubuntu LTS are too old. Could toolchans project add support for newer clang?

Is there any plan to upgrade from gcc 8.2 to gcc 9.2?

I like this shell script and newos very much, gcc 9.2 had released,Is there any plan to upgrade from gcc 8.2 to gcc 9.2?

cross compiler toolchains size

OS : Ubuntu 19.04
Branches 8.2 : GCCVER=8.2.0 + BINVER=2.31.1

I use cmd: ./doit -f -a "i386"
the size of my cross-compiler is too big(about 950M) , Can you tell me how to reduce size of cross-compiler tools?

How can I use this toolchain

After I build it,
I run ./arm-eabi-4.9.1/bin/arm-eabi-gcc hello.c
it says:
hello.c:1:18: fatal error: stdio.h: No such file or directory
#include<stdio.h>
^
compilation terminated.

then I run ./arm-eabi-4.9.1/bin/arm-eabi-gcc -I/usr/include hello.c
It says:
/opt/x-tools/arm-eabi-4.9.1/bin/../lib/gcc/arm-eabi/4.9.1/../../../../arm-eabi/bin/ld: cannot find crt0.o: No such file or directory
/opt/x-tools/arm-eabi-4.9.1/bin/../lib/gcc/arm-eabi/4.9.1/../../../../arm-eabi/bin/ld: cannot find -lc
collect2: error: ld returned 1 exit status

How can I run it?

And I think you should build libc or uclibc in the toolchian to solve the -lc problem.
