I added the "-v" flag to the setup.py that calls the compiler <https://github.com/ceph/ceph/blob/d9147a14c492afed3935b37ef3ef99a18067d0b7/src/pybind/cephfs/setup.py#L117>. The compiler did search the path /ceph/src/include for the header and the verbose output does not include any error message on missing header files. The compiler exception did not include more details other than "command '/opt/rh/gcc-toolset-11/root/usr/bin/gcc' failed with exit status 1". I also manually ran the compiler command per the log successfully. There was no compilation error or broken pipe. Anything else I can do to figure out what went wrong?

Thanks for all the help, Kefu. It looks like running ninja multiple times with different parallelism, possibly along with previous runs having failed or being killed, may cause failures? I created a new docker instance and repeated the same build steps, while limiting the ninja parallelism to 8, and the build was successful. As for the default parallel jobs, I can't find how to print out the default parallelism of the ninja command, but per the source code of ninja <https://github.com/ninja-build/ninja/blob/09b6b4e13a365ff04bc865fd6b4c6f1f52032617/src/ninja.cc#L250>, the command should have 10 parallel jobs as my container used 8 cores. Below are the steps I used: 1. docker run --name ceph-dev -it quay.io/centos/centos:stream8 /bin/bash 2. yum install git 3. git clone https://github.com/ceph/ceph 4. cd ceph 5. ./install-deps.sh 6. scl enable gcc-toolset-11 bash 7. gcc -v # verify that we are on gcc11 8. ./do_cmake.sh 9. cd build 10. ninja -j 8 # Initially I used only ninja, which would fail due to insufficient memory. I did run `scl enable gcc-toolset-11 bash` after running `./install-deps.sh`. The output of gcc -v. Using built-in specs.
