How to proceed with building FEX-Emu inside an arm64 container (for testing) #1878

Open Root-voidX opened 2 years ago

Root-voidX commented 2 years ago

Hello,

I am trying to to build FEX inside a CentOS-7 aarch64 container. How do I go about this (i.e. are there sepcific compile options I need to look into)? Next I have created a CentOS-7 x86_64 chroot with all the libraries I need for running my x86_64 program, how do I tell Fex to use the chroot I made?

If all goes well, I want to move this into my proot container as well (is FeX supported inside proot to?)

Thanks

Our wiki page has some information about specific options you would want to follow. https://wiki.fex-emu.com/index.php/Development:Setting_up_FEX#Build_Configuration

For configuring the rootfs there is a small guide here on the wiki about it. Slightly outdated but should be simple enough. https://wiki.fex-emu.com/index.php/Development:Setting_up_RootFS#Setting_RootFS_with_FEXConfig

FEX should work in proot but don't expect the performance to be amazing, Linux applications tend to heavily hit syscalls that Android doesn't support, so you hit the proot syscall emulation path.

Okay, so I made to sure to install all cross gcc packages and I also when in and made symlinks so the libraries that ended with so.X is linked to just .so.

I made it this far:

/usr/bin/../lib/gcc/aarch64-linux-gnu/4.8.5 This is because your build environment is significantly older than what we support. We require clang-10 (maybe 11 if we broke something?) and a significantly newer libstdc++. We require a compiler that supports C++20 minimum basically.

Sonicadvance1 commented 2 years ago

CentOS-8 at least has clang-12. Not sure if the rest of its packages are new enough.

Ahh, well centos7 is what my x86_64 software im trying to run only supports, it doesnt even work on centos 8. Can i use my centos-7 chroot in a different aarch host and will it work with FEX? If so I can just build this in fedora 35 aarch64 host?

Sonicadvance1 commented 2 years ago

A different distro chroot theoretically should work but you may encounter some weird things. Can only learn by trying.

Root-voidX commented 2 years ago

So i switched to fedora 35 aarch64, I got a bunch of warnings during ninja build, anything of concern?
