OCLint 未能发现 pre-compiled workspace/project headers

Question

我在尝试构建我的 OCLint 聚合时收到以下错误。

我们在工作区内使用 pre-compiled headers，虽然它们在主要目标和 OCLint 聚合中的引用完全相同，但出于某种原因，OCLint 聚合无法发现 pch。

这就是找不到“CocoaLumberjack/CocoaLumberjack.h”依赖项的原因。

我是运行 Xcode 7.1.1 OS X 10.11.1

Answer 1

更新： 我能够通过发出以下命令解决此问题：

xcodebuild -workspace MyWorkspace.xcworkspace -scheme MyScheme

Answer 2

我在尝试 run OCLint via pre-commit 时运行在 macOS Monterey (12.2) 上遇到了这个问题。来自 OCLint 的错误消息暗示缺少“编译数据库”，然后为系统 C 标准库 headers.

提供 'stdio.h' file not found

手动解决

解决方案是确保compile_commands.json 文件存在于top-level C 构建目录中。如果您使用 CMake，这显然是自动生成的，但该项目未使用 CMake。

手动创建文件成功：

compile_commands.json:

[
{
  "directory": ".",
  "command": "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc  -arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk -o enum-test.arm64.o -c enum-test.c",
  "file": "enum-test.c"
},
{
  "directory": ".",
  "command": "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc  -arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk -o test-args.arm64.o -c test-args.c",
  "file": "test-args.c"
},
{
  "directory": ".",
  "command": "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc  -arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk -o test-vars.arm64.o -c test-vars.c",
  "file": "test-vars.c"
},
{
  "directory": ".",
  "command": "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc  -arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk -o cidr_ranges.arm64.o -c cidr_ranges.c",
  "file": "cidr_ranges.c"
},
{
  "directory": ".",
  "command": "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc  -arch arm64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk -o rectangle.arm64.o -c rectangle.c",
  "file": "rectangle.c"
}
]

OCLint 错误信息：

对于我的情况，在为 .h header 文件提供 file not found 之前，错误提示缺少 compile_commands.json：
