The example: precompiled header pch.h: typedef unsigned int aaaa; labeling.h: #pragma once #include "pch.h" struct SomeStruct { }; labeling.cpp: #include "labeling.h" error here compile precompiled header with: g++ -g -O2 -c -x c++-header pch.h The compiling the labeling.cpp with: g++ -g -O2 labeling.cpp I get: In file included from pch.h:1: labeling.h:6: error: ‘error’ does not name a type The correct error message should be [which you get if precompiled header is removed]: labeling.cpp:3: error: ‘error’ does not name a type The gcc used is [gcc -v]: Using built-in specs.
