### Build Environment: Node version : v16.13.1 npm version : 8.3.0 make: GNU Make 3.81 gcc and g++ version 7.5.0 clang version: Apple clang version 13.0.0 (clang-1300.0.29.3) python: 3.9.7 xcode version : 13.0 OS: macOS ： 11.6 CPU: Intel Core i5 ### Install mediasoup-demo - mediasoup version: 3.9.3 ### Installation environment requirements node \>= v12.0.0 python \>= 3.6 GNU make `gcc` and `g++` \>= 4.9 > Meet the requirements ### bug description Build steps： ```auto > git clone https://github.com/versatica/mediasoup-demo.git > cd mediasoup-demo > git checkout v3 > cd server > npm install # wait > The error message is at the bottom ``` ### try 1. Use the command `PYTHON=python3.9 npm install mediasoup@3 --save` error - The error message is at the bottom 2. delet `node_modules` file ，And then trying `npm install` error - The error message is at the bottom No solution found online ```auto .... 4275 error [945/991] Compiling C++ object mediasoup-worker.p/src_RTC_UdpSocket.cpp.o 4275 error [946/991] Compiling C++ object

There must be something wrong with the compiler in your case. We run both GCC and Clang in CI and it works in both cases, I honestly can’t know what else might be wrong there. You can try to use `CC` and `CXX` environment variables to specify alternative compiler, but I have no idea which compiler you’re using as the beginning of the log is truncated (typically it is Apple’s Clang by default though). ---

Your suggestion works for me. I can see from your comment - The problem is with my compiler - Your use of gcc and clang is effective, indicating that I have a problem with the configuration of gcc and clang ### Solution: I changed a mac computer and reconfigured the environment, and it did compile successfully. > Explain that the problem lies in the compiler configuration > Personal feeling is caused by the environmental error of gcc and clang ### End > Finally, thank you for your suggestion ---

Can you tell me how you configue your compiler
