Resim build failure on Arch Linux: documentation/change suggestion

[rynoV]

I tried installing Resim (the simulator folder) on Arch Linux and ran into an error at the cargo install --path ./simulator step:

  error occurred: Command "sccache" "c++" "-O3" "-ffunction-sections" "-fdata-sections" "-fPIC" "-m64" "-I" "rocksdb/include/" "-I" "rocksdb/" "-I" "rocksdb/third-party/gtest-1.8.1/fused-src/" "-I" "snappy/" "-I" "lz4/lib/" "-I" "/home/calum/.local/share/.cargo/registry/src/github.com-1ecc6299db9ec823/zstd-sys-2.0.8+zstd.1.5.5/zstd/lib" "-I" "/home/calum/scripts/radix/radixdlt-scrypto/simulator/target/release/build/libz-sys-141b3fa7e129c0c6/out/include" "-I" "/home/calum/scripts/radix/radixdlt-scrypto/simulator/target/release/build/bzip2-sys-f5f4e66a40c6cff1/out/include" "-I" "."

There were also a bunch of errors like

  cargo:warning=In file included from rocksdb/table/block_based/data_block_hash_index.cc:9:
  cargo:warning=rocksdb/table/block_based/data_block_hash_index.h:65:7: error: ‘uint8_t’ does not name a type
  cargo:warning=   65 | const uint8_t kNoEntry = 255;
  cargo:warning=      |       ^~~~~~~
  cargo:warning=rocksdb/table/block_based/data_block_hash_index.h:1:1: note: ‘uint8_t’ is defined in header ‘<cstdint>’; did you forget to ‘#include <cstdint>’?
  cargo:warning=  +++ |+#include <cstdint>

LLVM and C++ were installed through arch's standard repositories. It was also the same error after disabling sccache.

At first I updated the rocksdb dependency in radix-engine-stores from 0.19.0 to 0.21.0, and this fixed the build for me and the install seemed to be successful. I'm not sure if this would silently break things though.

Then my colleague pointed out that Arch's default gcc installation has some breaking changes, so the fix was:

1. Install libc++ via pacman

2. Set the environment variables: export CC=clang CXX=clang++ CXXFLAGS="-stdlib=libc++"

3. In the simulator folder, add a build.rs file with contents:

   fn main() {
     println!("cargo:rustc-link-lib=c++");
   }

And this also fixed the installation.

This solved build errors for me on my Manjaro linux system.

error: failed to compile simulator v0.9.0

I have attempted the above remedies. Still getting the error above when installing resim in Arch Linux.
