How to build the cross compiler for x86_64?

I changed TARGET to "x86_64-linux-gnu", and LINUX_ARCH to "x86_64" in the script, but I got the follow error at the stage building glibc:

Is there a version to build gcc 5.3.x?

used this guide to compile GCC 6.1 with latest GLibc and 4.6 Kernel , thank you for your efforts

pwaring commented May 18, 2016

@Vladinator You should be able to build 5.3.x with this. If not, I've created a similar script with slightly higher levels of abstraction which definitely builds GCC 4.9.x, 5.3.x and 6.1: https://github.com/pwaring/gcc-cross-compiler

Thanks @pwaring, maybe you can add a note at the top of your blog post for the github repository?

mdeguzis commented Jul 23, 2016

Anyone get this to build fine on amd64? @pwaring, I don't see support for amd64 in that, is it possible?

My current version of this script with some improvements:
https://github.com/ProfessorKaos64/LibreGeek-Packaging/blob/brewmaster/gcc/build-cross-gcc.sh

@BaoshanPang - my version of this script above seems to work until a point:

U007D commented May 6, 2017

I'm building for a RaspberryPi3 running Raspbian, so I want to build my cross-compiler for a 32-bit Linux target. (I'm on Mac OS X Sierra 10.12.4, if that matters.) Should I use arm-linux? armv7-unknown-gnueabihf? Something else?

Fairly new to this, so in addition to knowing the proper 32-bit target identifier for the RPi3, I'd like to know how/where to find the list of valid targets.

Thank you for this and the blog article!

U007D commented May 6, 2017

Incidentally I'm here looking at the script, because in following the steps on your blog, I got an error on Step 4.

I'm on Mac OS X Sierra 10.12.4. No errors (modulo having to unpack linux-4.4.38 to a case-sensitive filesystem in order for it to install properly) following Steps 1-3.

At Step 4, though, I got the following:

$ ../glibc-2.19/configure --prefix=/usr/local/bin/gcc-7.1.0-armv7-linux-gnueabihf/armv7-linux-gnueabihf --build=$MACHTYPE --host=armv7-linux-gnueabihf --target=armv7-linux-gnueabihf --with-headers=/usr/local/bin/gcc-7.1.0-armv7-linux-gnueabihf/include --disable-multilib libc_cv_forced_unwind=yes
checking build system type... x86_64-apple-darwin16
checking host system type... armv7-unknown-linux-gnueabihf
checking for armv7-linux-gnueabihf-gcc... /usr/local/bin/gcc-7.1.0-armv7-linux-gnueabihf/bin/armv7-linux-gnueabihf-gcc
...
checking whether to put _rtld_local into .sdata section... no
checking for .preinit_array/.init_array/.fini_array support... no
configure: error: Need linker with .init_array/.fini_array support.

I've tried several Google searches and a number of variations of the above configure command, but no luck.

Any ideas on how to fix this?

--

Some background, in case it helps:

  • Followed steps 1-4 exactly, changing only the target (armv7-unknown-gnueabihf for 32-bit ARM) and the install path (/usr/local/bin/gcc-7.1.0-armv7-unknown-gnueabihf).
  • Compiled using gcc v7.1.0 using the following versions of the gcc components to best match the kernel version used for the Raspberry Pi 3's Raspbian Linux or otherwise used the latest version:
    • binutils v2.28
    • glibc v2.19
    • gmp v6.1.2
    • isl v0.16.1
    • linux 4.4.38
    • mpc v1.0.3
    • mpfr v3.1.5
