Configuring QEMU with:
configure --target-list="x86_64-softmmu" --cc=clang --enable-pvrdma
Results in:
qemu/hw/rdma/rdma_rm_defs.h:108:3: error: redefinition of typedef 'RdmaDeviceResources' is a C11 feature [-Werror,-Wtypedef-redefinition]
} RdmaDeviceResources;
^
qemu/hw/rdma/rdma_backend_defs.h:24:36: note: previous definition is here
typedef struct RdmaDeviceResources RdmaDeviceResources;
Fix by removing one of the 'typedef' definitions.
