Method that has been tried

1. scl enable llvm-toolset-7
2. yum update cmake
3. yum update gcc/g++
4. use a new OS to build in strict accordance with the documentation

I encounter the same error on Fedora 30. I manage to get around this by setting environment variables CPLUS_INCLUDE_PATH to "/usr/lib/gcc/x86_64-redhat-linux/9/include".

[Ten0]

Same error on my fully up to date ArchLinux and on our Debian stretch deployment system. Latest release broke quite some builds.

[light4]

Same here, I find that cargo cache don't have third_party/protobuf directory.

@Ten0 from 0.5.0-alpha.2, grpcio-sys depends on clang and clang library. Have you installed those libraries?

@light4 It has nothing to do with protobuf. The error is reported by bindgen, which requires clang toolchains.

[light4]

quick fix

# centos
yum install clang clang-devel llvm llvm-devel

# archlinx
# add this line to bindgen config at build.rs:259
.clang_arg("-I/usr/lib/clang/8.0.0/include")

[BusyJay]

Hmm, can you help us to add the dependencies to Prerequisites? @light4

[hunterlxt]

it seems like there is only 3.4.2 in yum repo

[light4]

yep, but it should be fine, can you test it?

[hunterlxt]

doesn't work, I think building from source could fix @light4

[light4]

I try to build it on centos 7.1, it builds successfully. Can you paste the error logs here?

llvm 3.4.2
clang 3.4.2
CentOS Linux release 7.1.1503 (Core)
