2016年10月2日 · A .gch file is a precompiled header. If a .gch is not found then the normal header files will be used. However, if your project is set to generate pre-compiled headers it will make them if they don’t exist and use them in the next build. Sometimes the *.h.gch will get corrupted or contain outdated information, so deleting that file and compiling it again should fix it.

2020年3月9日 · We are making a makefile for a class project, and we are having problems with gcc generating .h.gch files. Looked around on stack overflow and apparently it is normally caused by either including .h

2014年5月30日 · Using GCH (Gnu preCompiled Headers) is easy, at least in theory. How to create a GCH Just use gcc <compiler-options> myfile.h. That will create myfile.h.gch. You can use the -o <name> to specify the name of the output file. If your header file is C++, you will have to name it myfile.hpp or myfile.hh, or GCC will try to compile it as C and probably fail. Alternatively you can use the -x c++ ...

2015年4月6日 · Using GCC to compile C code, GCC automatically generate .h.gch files. Question How do I suppress this?

2018年10月30日 · By default gcc generates .gch precompiled headers. However clang expects .pch headers. When running scan-build with clang on an otherwise gcc based project, I get errors due to this. What are the differences between the two file formats that might cause this problem?

2012年5月25日 · Call GCC the same way as if you call it for your source file, but with a header file. E.g., g++ $(CPPFLAGS) test.h This generates a file called test.h.gch. Every time GCC searches for test.h, it looks first for test.h.gch and if it finds it it uses it automatically. More information can be found under GCC Precompiled Headers.

2009年10月1日 · So, I'm making a program to test the efficiency of certain data structures. I have all the .h files and I made a very terrible makefile that probably is wrong, although it seems to work up to a po...

2021年6月16日 · Macro definitions must be IDENTICAL. So defining your PCH define is not going to work. And it looks like your rule to produce the gch file is producing assembler output. That won't work, ever. And I found it was important to specifically declare the type of header, in my case I had to use -x c++-header $< but you probably want c-header

2021年11月28日 · Is there a way to check to see if GCC uses the precompiled header or not? Also, I generate pch.h.gch file like this: g++ -std=c++20 -Wall -O3 -flto pch.h -o pch.h.gch But the generated file is always named as pch.h and without the .gch extension. Why is this happening? It used to automatically add the extension. But now it doesn't.

2011年6月21日 · I accidentally removed a .h file I hadn't added to version control, but I still have the .h.gch. Is there any way to uncompile the .gch?
