Does GRPC C++ support OpenSSL3.0 compilation?

[小煤球]

When I tried to compile grpc, I changed the OpenSSL version to 3.0, but many undefined errors occurred during the compilation.

[veb...@google.com]

I don't think gRPC supports OpenSSL 3.0 yet as we have https://github.com/grpc/grpc/pull/31256 open.

But it's puzzling to me that you saw many undefined errors. I expected that it should be compile errors due to API breaking changes or runtime errors due to potential API behavior changes.

i am facing link errors when i use openssl3.0 , please guide. My application package uses 3.0 openssl .Trying to integrate this package with grpc.

[Daksha Tulshikar]

are there any plans to support openssl 3.0?

Hi Esun,

Thanks for the update.

I am using the latest grpc v1.66.0

git clone --recurse-submodules -b v1.66.0 --depth 1 --shallow-submodules https://github.com/grpc/grpc

So will it work with openssl 3.0.7 or 3.0.8 ?

I first installed grpc with default boringssl and then installed

with openssl installed on my system (1.1.1g) ie with

cmake -DgRPC_INSTALL=ON \
-DgRPC_SSL_PROVIDER=package \
      -DgRPC_BUILD_TESTS=OFF \
      -DCMAKE_INSTALL_PREFIX=$MY_INSTALL_DIR \
      ../..

This worked for me.

since grpc v1.66 will work with openssl 3.0.7 , i will try with that as well. My application works on openssl 3.0.7.

correction , my application works on openssl  1.1.1c ,will try with that.

Hi Esun,

I have an application which uses openssl v 1.1.1c.

I am trying to integrate with grpc , it compiles and links properly, but when i run it throws a segmentation fault (core dump). The issue points to libcrypto.so. 

Can you please guide me on installing grpc (any specific version?) and the steps to install, so that it is compatible with openssl v1.1.1c?

Trying for many days. Appreciate your help

regards

Daksha
