will support for 1.88.0 ?

[taoistwar]

rust upgrade to 1.88.0, will support ?

[trinitronx]

I'm wondering about the same question. Currently it doesn't look like it's supported officially.

I tried running install.sh with the following patch, but I ran into an error.

Seems that there is a check for supported rustc version :

/// The same `rustc` version must be used to compile the debugger and the target executable.
/// This is due to implicit ABI dependency everywhere.
pub fn check_rustc_version() {
    let rustc_version = rustc_version();
    if rustc_version != SUPPORTED_RUSTC_VERSION {
        panic!("Mismatched `rustc` version: expect `{SUPPORTED_RUSTC_VERSION}`, found `{rustc_version}`. Please install a matching FireDBG version.");
    }
}

Which is what printed the error above:

Mismatched `rustc` version: expect `1.81`, found `1.88`. Please install a matching FireDBG version.

So, the pre-packaged version 1.81 of FireDBG will not work. We must build it ourselves...

I tried to build it manually on my machine which is running Manjaro Linux (Arch Linux family OS):

$ git clone https://github.com/SeaQL/FireDBG.for.Rust.git 
$ cd FireDBG.for.Rust/debugger/

$ export CXX=$(which clang++) CXXFLAGS='-I /usr/include/c++/v1/'; cargo build --verbose

Note that I had to install packages for LLVM + libc++ headers for the -I / C++ stdlib include:

$ sudo pacman -Sy llvm llvm-libs libc++

If I did not have these installed, or set CXX / CPPFLAGS before running cargo build, I got these errors:

Expand for g++ / clang++ FireDBG build errors:

If we don't override CXX, then g++ from GCC is used by default. Yet, it doesn't support the -stdlib=libc++ flag that clang++ does. So we get the following error:

 cargo:warning=c++: error: unrecognized command-line option ‘-stdlib=libc++’

If we set only CXX=$(which clang++) to override the default compiler toolchain (GCC) with LLVM, but we don't set CPPFLAGS, then we get a missing C++ stdlib include error.

It's equivalent to running this command without -I /usr/share/libc++/v1/:

warning: build failed, waiting for other jobs to finish...

To find the correct include path for CPPFLAGS=-I ..., I checked the contents of the libc++ package for the /new include path (from the #include <new> error above):

$ pacman -Ql libc++ | grep -i '/new'

libc++ /usr/include/c++/v1/__cxx03/__locale_dir/locale_base_api/newlib.h
libc++ /usr/include/c++/v1/__cxx03/new
libc++ /usr/include/c++/v1/__new/new_handler.h
libc++ /usr/include/c++/v1/new
libc++ /usr/share/libc++/v1/std/new.inc

So, on my system the include path for the LLVM C++ stdlib to pass to the toolchain should be: -I /usr/include/c++/v1/.

To find this on Ubuntu or Debian-based Linux distros, check the output of dpkg -l libc++-dev instead.

You'll likely need to install the ABI package also: sudo apt install libc++-dev libc++abi-dev.

For Debian & Ubuntu you might be able to avoid setting CXX and CPPFLAGS if using update-alternatives to symlink g++ to clang++, etc...

sudo update-alternatives --config c++
# Select LLVM / clang++ when prompted

As far as the result goes... I'm not sure if I can trust it because the tests did not pass:
