## Debugging with XCode
|
|
|
|
### Build Debug Electron with Release libchromiumcontent
|
|
You can create a debug build of electron by following [build instructions for macOS](build-instructions-osx.md).
|
|
The bootstrap process will download Release version of libchromiumcontent by default,
|
|
so you will not be able to step through the chromium source.
|
|
|
|
### Build Debug Electron with Debug libchromiumcontent
|
|
If you want to debug and step through libchromiumcontent, you will have to run the
|
|
bootsrap script with the `--build_debug_libcc` argument.
|
|
|
|
```sh
|
|
$ cd electron
|
|
$ ./script/bootstrap.py -v --build_debug_libcc
|
|
```
|
|
This can take a significant amount of time depending on build machine as it has to
|
|
build all of the libchromium source.
|
|
|
|
Once, the lib is built, create a symlink to the built directory under download
|
|
|
|
`ln -s vendor/libchromiumcontent/dist/main/shared_library vendor/download/libchromiumcontent/shared_library`
|
|
|
|
Electron debug builds will use this shared library to link against.
|
|
|
|
```sh
|
|
$ ./script/build.py -c D --libcc
|
|
```
|
|
This will build debug electron with debug version of libchromiumcontent.
|
|
|
|
### Generate xcode project for debugging sources (cannot build code from xcode)
|
|
Run the update script with the --xcode argument.
|
|
```sh
|
|
$ ./script/update.py --xcode
|
|
```
|
|
This will generate the electron.ninjs.xcworkspace. You will have to open this workspace
|
|
to set breakpoints and inspect.
|
|
|
|
### Debugging and breakpoints
|
|
|
|
Launch electron app after build.
|
|
You can now open the xcode workspace created above and attach to the electron process
|
|
through the Debug > Attach To Process > Electron debug menu. [Note: If you want to debug
|
|
the renderer process, you need to attach to the Electron Helper as well.]
|
|
|
|
You can now set breakpoints in any of the indexed files. However, you will not be able
|
|
to set breakpoints directly in the chromium source.
|
|
To set break points in the chromium source, you can choose Debug > Breakpoints > Create
|
|
Symbolic Breakpoint and set any function name as the symbol. This will set the breakpoint
|
|
for all functions with that name, from all the classes if there are more than one.
|
|
You can also do this step of setting break points prior to attaching the debugger,
|
|
however, actual breakpoints for symbolic breakpoint functions may not show up until the
|
|
debugger is attached to the app. |
