make -j

Expected behavior
编译成功。

Versions

Compiler: gcc (GCC) 12.3.1
brpc: 1.15.0
protobuf: 3.14.0

Additional context/screenshots

[wasphin]

Please try to add CXXLFAGS="-std=c++17" in the WITH_BTHREAD_TRACER checking block for a workaround

brpc/config_brpc.sh

Line 359 in 50a9075

if [ $WITH_BTHREAD_TRACER != 0 ]; then

will recheck the absl dependencies later.

Thanks for your feedback! There appears to be an issue related to the Protobuf version. The openEuler OS ships with protobuf.x86_64 25.1-11.oe2403sp2, which leads to compilation errors when building BRPC. I therefore switched to protobuf.x86_64 3.14.0-8.oe2203sp2, and the BRPC build runs successfully without enabling the bthread-tracer feature. However, the build fails when enabling with-bthread-tracer.
