基于 libclang 编译 C 文件的坑（ error: unknown type name 'uint8_t' ）

查找问题：
我 直接使用 mac 平台 Xcode 的 clang 直接编译目标文件
clang -c xxxxx.cpp是能够正常编译的。没有报错。
1、 为 Mac 的 clang 和 代码中的 libclang 各自 添加 -v 参数 比较 回显的 命令行参数差异， 仍然没有找到解决问题的线索。（因为数量庞大 爬了挺久的坑）
2、网上搜的 方案都是 所 需要 修改 usr/local/include 路径，认为是系统升级导致 clang 环境 头文件 被破坏了。我这里 命令行 clang 是能够正常编译 肯定不是这个问题。
3、别人提供的思路。 我重新弄了个 C 文件， 仍然通过 libclang 来编译, 错误依旧。然后就有点懵。这里又 爬了很久的坑 不知道为什么！ 知道 跟 stdint.h 相关 但是 下面的代码我去掉这个头文件仍然报错！
编译的是下面这个文件， 此文件内容来自互联网：
#include <stdint.h>
#include <stdio.h>
#include <stdlib.h>
int main( int argc, char **argv )
{
uint64_t u64 = 3;
int32_t i32 = 141;
printf( "u64 = %lu\n", u64 );
printf( "i32 = %d\n", i32 );
return 0;
}后来无意中 觉得 这是一个单独的文件 所以编译参数 去掉了搜索路径 也就是上面代码中的 searchPath 部分 发现 上面的那个错误消失了！！！
4、进一步 减小搜索路径的范围 最终确认 问题！ 因为我指定的搜索路径 是 递归查找，它的子目录中 包含了一个 stdint.h。 内容如下：
#ifndef _MSC_STDINT_H_ // [
#define _MSC_STDINT_H_
#include "CCPlatformConfig.h"
#if CC_TARGET_PLATFORM == CC_PLATFORM_WIN32
#ifndef _MSC_VER // [
#error "Use this header only with Microsoft Visual C++ compilers!"
#endif // _MSC_VER ]
#if _MSC_VER > 1000
#pragma once
#endif
#include <limits.h>
...而我 当前平台是 Mac。 导致 stdint.h 无法包含进来。
找到问题就 把 win 搜索路径排除就好了。
这个坑 也是 蛋疼。记录下 也可以为类似问题 提供个思路。
这里贴一下 Mac 下 clang 的 参数列表。
CLANG(1) Clang CLANG(1)
NAME
clang - the Clang C, C++, and Objective-C compiler
SYNOPSIS
clang [options] filename ...
DESCRIPTION
clang is a C, C++, and Objective-C compiler which encompasses preprocessing, parsing, optimization, code gen-
eration, assembly, and linking. Depending on which high-level mode setting is passed, Clang will stop before
doing a full link. While Clang is highly integrated, it is important to understand the stages of compilation,
to understand how to invoke it. These stages are:
Driver The clang executable is actually a small driver which controls the overall execution of other tools
such as the compiler, assembler and linker. Typically you do not need to interact with the driver, but
you transparently use it to run the other tools.
Preprocessing
This stage handles tokenization of the input source file, macro expansion, #include expansion and han-
dling of other preprocessor directives. The output of this stage is typically called a ".i" (for C),
".ii" (for C++), ".mi" (for Objective-C), or ".mii" (for Objective-C++) file.
Parsing and Semantic Analysis
This stage parses the input file, translating preprocessor tokens into a parse tree. Once in the form
of a parse tree, it applies semantic analysis to compute types for expressions as well and determine
whether the code is well formed. This stage is responsible for generating most of the compiler warnings
as well as parse errors. The output of this stage is an "Abstract Syntax Tree" (AST).
Code Generation and Optimization
This stage translates an AST into low-level intermediate code (known as "LLVM IR") and ultimately to
machine code. This phase is responsible for optimizing the generated code and handling target-specific
code generation. The output of this stage is typically called a ".s" file or "assembly" file.
Clang also supports the use of an integrated assembler, in which the code generator produces object
files directly. This avoids the overhead of generating the ".s" file and of calling the target assem-
bler.
Assembler
This stage runs the target assembler to translate the output of the compiler into a target object file.
The output of this stage is typically called a ".o" file or "object" file.
Linker This stage runs the target linker to merge multiple object files into an executable or dynamic library.
The output of this stage is typically called an "a.out", ".dylib" or ".so" file.
Clang Static Analyzer
The Clang Static Analyzer is a tool that scans source code to try to find bugs through code analysis. This
tool uses many parts of Clang and is built into the same driver. Please see <https://clang-analyzer.llvm.org>
for more details on how to use the static analyzer.

cl1.0
OpenCL 1.0
cl1.1
OpenCL 1.1
cl1.2
OpenCL 1.2

ified, platform default will be used.
-ansi Same as -std=c89.
-ObjC, -ObjC++
Treat source input files as Objective-C and Object-C++ inputs respectively.
-trigraphs
Enable trigraphs.
-ffreestanding
Indicate that the file should be compiled for a freestanding, not a hosted, environment. Note that it
is assumed that a freestanding environment will additionally provide memcpy, memmove, memset and memcmp
implementations, as these are needed for efficient codegen for many programs.
-fno-builtin

-fmsc-version=
Set _MSC_VER. Defaults to 1300 on Windows. Not set otherwise.
-fborland-extensions
Enable support for Borland extensions.
-fwritable-strings
Make all string literals default to writable. This disables uniquing of strings and other optimiza-
tions.
-flax-vector-conversions, -flax-vector-conversions=<kind>, -fno-lax-vector-conversions
Allow loose type checking rules for implicit vector conversions. Possible values of <kind>:
o none: allow no implicit conversions between vectors
o integer: allow implicit bitcasts between integer vectors of the same overall bit-width
o all: allow implicit bitcasts between any vectors of the same overall bit-width
<kind> defaults to integer if unspecified.
-fblocks
Enable the "Blocks" language feature.
-fobjc-abi-version=version
Select the Objective-C ABI version to use. Available versions are 1 (legacy "fragile" ABI), 2
(non-fragile ABI 1), and 3 (non-fragile ABI 2).
-fobjc-nonfragile-abi-version=<version>
Select the Objective-C non-fragile ABI version to use by default. This will only be used as the Objec-
tive-C ABI when the non-fragile ABI is enabled (either via -fobjc-nonfragile-abi, or because it is the
platform default).
-fobjc-nonfragile-abi, -fno-objc-nonfragile-abi
Enable use of the Objective-C non-fragile ABI. On platforms for which this is the default ABI, it can
be disabled with -fno-objc-nonfragile-abi.
Target Selection Options
Clang fully supports cross compilation as an inherent part of its design. Depending on how your version of
Clang is configured, it may have support for a number of cross compilers, or may only support a native target.
-arch <architecture>
Specify the architecture to build for.
-mmacosx-version-min=<version>
When building for macOS, specify the minimum version supported by your application.
-miphoneos-version-min
When building for iPhone OS, specify the minimum version supported by your application.
--print-supported-cpus
Print out a list of supported processors for the given target (specified through --target=<architec-
ture> or -arch <architecture>). If no target is specified, the system default target will be used.
-mcpu=?, -mtune=?
Aliases of --print-supported-cpus
-march=<cpu>
Specify that Clang should generate code for a specific processor family member and later. For example,
if you specify -march=i486, the compiler is allowed to generate instructions that are valid on i486 and
later processors, but which may not exist on earlier ones.
Code Generation Options
-O0, -O1, -O2, -O3, -Ofast, -Os, -Oz, -Og, -O, -O4
Specify which optimization level to use:
-O0 Means "no optimization": this level compiles the fastest and generates the most debuggable code.
-O1 Somewhere between -O0 and -O2.
-O2 Moderate level of optimization which enables most optimizations.
-O3 Like -O2, except that it enables optimizations that take longer to perform or that may generate
larger code (in an attempt to make the program run faster).
-Ofast Enables all the optimizations from -O3 along with other aggressive optimizations that may
violate strict compliance with language standards.
-Os Like -O2 with extra optimizations to reduce code size.
-Oz Like -Os (and thus -O2), but reduces code size further.
-Og Like -O1. In future versions, this option might disable different optimizations in order to
improve debuggability.
-O Equivalent to -O1.
-O4 and higher
Currently equivalent to -O3
-g, -gline-tables-only, -gmodules
Control debug information output. Note that Clang debug information works best at -O0. When more than
one option starting with -g is specified, the last one wins:
-g Generate debug information.
-gline-tables-only Generate only line table debug information. This allows for symbolicated back-
traces with inlining information, but does not include any information about variables, their loca-
tions or types.
-gmodules Generate debug information that contains external references to types defined in Clang
modules or precompiled headers instead of emitting redundant debug type information into every
object file. This option transparently switches the Clang module format to object file containers
that hold the Clang module together with the debug information. When compiling a program that uses
Clang modules or precompiled headers, this option produces complete debug information with faster
compile times and much smaller object files.
This option should not be used when building static libraries for distribution to other machines
because the debug info will contain references to the module cache on the machine the object files
in the library were built on.
-fstandalone-debug -fno-standalone-debug
Clang supports a number of optimizations to reduce the size of debug information in the binary. They
work based on the assumption that the debug type information can be spread out over multiple compila-
tion units. For instance, Clang will not emit type definitions for types that are not needed by a mod-
ule and could be replaced with a forward declaration. Further, Clang will only emit type info for a
dynamic C++ class in the module that contains the vtable for the class.
The -fstandalone-debug option turns off these optimizations. This is useful when working with
3rd-party libraries that don't come with debug information. This is the default on Darwin. Note that
Clang will never emit type information for types that are not referenced at all by the program.
-fexceptions
Enable generation of unwind information. This allows exceptions to be thrown through Clang compiled
stack frames. This is on by default in x86-64.
-ftrapv
Generate code to catch integer overflow errors. Signed integer overflow is undefined in C. With this
flag, extra code is generated to detect this and abort when it happens.
-fvisibility
This flag sets the default visibility level.
-fcommon, -fno-common
This flag specifies that variables without initializers get common linkage. It can be disabled with
-fno-common.
-ftls-model=<model>
Set the default thread-local storage (TLS) model to use for thread-local variables. Valid values are:
"global-dynamic", "local-dynamic", "initial-exec" and "local-exec". The default is "global-dynamic".
The default model can be overridden with the tls_model attribute. The compiler will try to choose a
more efficient model if possible.
-flto, -flto=full, -flto=thin, -emit-llvm
Generate output files in LLVM formats, suitable for link time optimization. When used with -S this
generates LLVM intermediate language assembly files, otherwise this generates LLVM bitcode format
object files (which may be passed to the linker depending on the stage selection options).
The default for -flto is "full", in which the LLVM bitcode is suitable for monolithic Link Time Opti-
mization (LTO), where the linker merges all such modules into a single combined module for optimiza-
tion. With "thin", ThinLTO compilation is invoked instead.
NOTE:
On Darwin, when using -flto along with -g and compiling and linking in separate steps, you also need
to pass -Wl,-object_path_lto,<lto-filename>.o at the linking step to instruct the ld64 linker not to
delete the temporary object file generated during Link Time Optimization (this flag is automatically
passed to the linker by Clang if compilation and linking are done in a single step). This allows
debugging the executable as well as generating the .dSYM bundle using dsymutil(1).
Driver Options
-### Print (but do not run) the commands to run for this compilation.
--help Display available options.
-Qunused-arguments
Do not emit any warnings for unused driver arguments.
-Wa,<args>

clang_rt.builtins.*.a").
-print-prog-name=<name>
Print the full program path of name.
-print-search-dirs

Save internal code generation (LLVM) statistics to a file in the current directory (-
-save-stats/"-save-stats=cwd") or the directory of the output file ("-save-state=obj").
-integrated-as, -no-integrated-as
Used to enable and disable, respectively, the use of the integrated assembler. Whether the integrated
assembler is on by default is target dependent.
-time Time individual commands.
-ftime-report
Print timing summary of each stage of compilation.
-v Show commands to run and use verbose output.
Diagnostics Options
-fshow-column, -fshow-source-location, -fcaret-diagnostics, -fdiagnostics-fixit-info, -fdiagnos-
tics-parseable-fixits, -fdiagnostics-print-source-range-info, -fprint-source-range-info, -fdiagnos-
tics-show-option, -fmessage-length
These options control how Clang prints out information about diagnostics (errors and warnings). Please
see the Clang User's Manual for more information.
