[c3c on aarch64] wont compile on termux

[TymekBrunka]

Minor isssue, just wanted to try out c3 and also do c3 stuff on phone but there are no release binaries for arm.

Is is possible to compile c3c on and for aarch64?

As long as you're able to compile LLVM and LLD for it so you have those libraries, it should be straightforward to compile c3c.

Maybe you only have dynamically linked libraries available? If so the use -DC3_LINK_DYNAMIC=true with CMake.

[lerno]

Were you able to solve this?

[lerno]

Should I close this?

[TymekBrunka]

...

[TymekBrunka]

there is no /usr/local on termux and the flag doesnt work both with and without -DLLVM_DIR

[lerno]

Did you try the -DC3_LINK_DYNAMIC=true flag?

[TymekBrunka]

yes, that's the flag i was talking about

[lerno]

So you get the CMake error?

[TymekBrunka]

yes (just found out that there are libllvm and libllvm-static separetely and installed libllvm-static) and btw what is (/usr)/bin/FileCheck that it failed to find?

[lerno]

This is what it failed to get libLLVMDemangle

[TymekBrunka]

do i have to install it or what?

[lerno]

It is (unfortunately) not unusual that the LLVM libs are broken. So I would look for maybe earlier or later LLVM packages and see if they work. The error you see is in LLVM's own CMake script(!) which is run before any C3 compilation.

[TymekBrunka]

Ok, so basicly termux llvm doesnt support even setting up build directory, ok, thank you for info.

[lerno]

We'll try to set up LLVM builds for various linux variants later, that way we'll have everyone covered regardless of LLVM support through package managers.
