01:37 <Na_Klar> I'm comming further with my try to port crystal to riscv. I use the bootstrap script and everything compiled fine so far execpt crystal won't. this is the log: https://paste.debian.net/1232285/ .. unfortunately the ruby error is not saying anything sane. what can I do here?

01:42 <Na_Klar> ah, the output was cut, here are the ruby errors: https://pastebin.com/mDA9anmZ

01:49 <Na_Klar> .. looks to me like there is a memory issue with the C module ..

01:59 <Na_Klar> ah no, it seems like it is a target triple problem again. the relevant ruby error line say: Unable to find target for this triple (no targets are registered). For compiling llvm and gems I had to use ./configure --build=riscv64-unknown-linux-gnu to workaround auto-guessing the target. seems like the ruby compiler also expects a triple, which it couldn't find, but irritating is that there seems no target to be registered at all ..

02:22 <FromGitter> <Blacksmoke16> https://doc.rust-lang.org/nightly/rustc/platform-support.html

02:22 <FromGitter> <Blacksmoke16> Rust also uses LLVM, so the target triple should be the same, assuming you know/figure out which one to use

02:26 <Na_Klar> llvm-config on that machine gave the triple above. with that I could compile llvm (from the bootstrap script) as well as gems. (both needed to be configured with the target, because auto-guessing failed.)

02:26 <FromGitter> <Blacksmoke16> ah gotcha

02:27 <Na_Klar> but now it is the script which compiles crystal which fails with the pasted error. the error implies that there is not target registered and no target found.

02:28 <FromGitter> <Blacksmoke16> what if you just try cross compiling?

02:28 <Na_Klar> when I look into the code it seems like a C. module is trying to set some pointer in the memory .. dunno what that have to do with targets ...

02:28 <FromGitter> <Blacksmoke16> https://crystal-lang.org/reference/1.3/syntax_and_semantics/cross-compilation.html

02:29 <Na_Klar> I could try that now, since I have a little more knowledge about how that works, but my original aim was to bootstrap crystal to at least 0.3 ..

02:29 <FromGitter> <Blacksmoke16> in theory you should just be able to use your local crystal, cross compile it to that target, move some files over there, link it, and be good to go

02:29 <FromGitter> <Blacksmoke16> which should give you current version crystal on it

02:29 <FromGitter> <Blacksmoke16> which could be used to play around with bindings and stuff to get it to compile itself

02:36 <Na_Klar> hm, a first quick try to cross-compile resulted in Unsupported architecture for target triple ..

02:39 <FromGitter> <Blacksmoke16> welp, guess theres some groundwork required for that to work then

02:39 <Na_Klar> llvm is version 7.0.1 .. since which version does llvm support riscv64 again? (not sure, was it 9?)

02:39 <FromGitter> <Blacksmoke16> https://github.com/crystal-lang/crystal/blob/dd40a2442fa186add8a82b74edb14a90aa1dae05/src/compiler/crystal/codegen/target.cr#L133-L149

02:40 <FromGitter> <Blacksmoke16> its a crystal thing, just tried on 13 and got same error

02:40 <Na_Klar> ah ok
