I've been trying to cross compile the source code to build GCC 12.2.0 for my RaspberryPi 4 B running Ubuntu 22.04. SO far I've tried doing this while configuring the project:

../gcc-12.2.0/configure --build=x86_64-pc-linux-gnu --host=aarch64-linux-gnu --enable-languages=c,c++ --prefix-path=/opt/cross/gcc-12.2.0/build_aarch64 --disable-multilib

But this does not work, as when I'm building the project using make, the bootstrapping phase gives me a bunch of errors related to zstd.

undefined reference to `ZSTD_getErrorName' undefined reference to `ZSTD_isError' undefined reference to `ZSTD_compress' undefined reference to `ZSTD_getErrorName' ... (you get it)

How do I go about solving this? Am I doing something wrong configuring my project? I've been looking at this from just straight up searching my error: https://github.com/crosstool-ng/crosstool-ng/issues/1613, but it seems like scuffing it a bit, right?

Would appreciate your help, guys.

  • Is there a particular reason you’re trying to compile this yourself, rather than use the g++-12-aarch64-linux-gnu cross-compiler package? Commented Jun 1, 2024 at 8:10
  • That's based on GCC 12.3.0, right? I'm looking for something that's specifically GCC 12.2.0. Commented Jun 1, 2024 at 15:45
  • What is different in this snippet compared to e.g. Musl-LFS are the different parameters for --build and --host, which in Musl-LFS are equal, and the lack of --target. The original LFS has only --target in the first step, and --host equal to --target in the second step Commented Jun 1, 2024 at 16:41
  • Also, are you sure the aarch64-linux-gnu is the correct triplet? LFS contains a section on "system triplets", which should actually consist of four parts. Commented Jun 1, 2024 at 17:06
  • @Vilinkameni the triplet is fine, but your point about the arguments is a good one — it all depends on whether the goal is to cross-compile a native ARM64 compiler, or compile an x86-to-ARM64 cross-compiler. Commented Jun 1, 2024 at 19:24

Since you’re trying to cross-compile a native ARM64 compiler, you need to install the required libraries and development files for ARM64. On Ubuntu, the easiest way to do this is to enable arm64:

sudo dpkg --add-architecture arm64 sudo apt update

Then you’ll be able to install libraries using :arm64:

sudo apt install libzstd-dev:arm64

You’ll need to repeat that with any other library needed to build GCC.

  • Great idea. Let me try. Commented Jun 2, 2024 at 21:46
  • Now I'm getting some Assembler errors, no such architecture armv8, ... Which library should I install here? Commented Jun 3, 2024 at 1:21
