问题 After installing and building Fuchsia OS, I can modify the string in the example hello world program from "Hello, World!\n" to "Hello, Fuchsia!\n". Then I build and execute the code which produces the expected string "Hello, Fuchsia!" using: cd fuchsia fx set bringup.x64 --with //examples/hello_world fx build; fx qemu hello_world_cpp This is fine for understanding how to change part of the Fuchsia "distribution". How do I create my own program outside of the fuchsia tree? I assume one would

问题 Problem Summary I'm trying to integrate Google Crashpad, (successor of Google Breakpad) a crash reporting system, into a software suite that links to all of its external libraries dynamically. My problem is that the default of Crashpad is to build as a static library - I need to build it dynamically . After cloning Crashpad, GN is used to generate the .ninja files for the build. The build commands are as follows: $ gn gen out/Default The above command generates all of the .ninja files. (Aside

问题 Crashpad is an error reporting system for c++ apps. https://chromium.googlesource.com/crashpad/crashpad/+/HEAD/doc/developing.md build instructions are $ cd ~/crashpad/crashpad $ gn gen out/Default $ ninja -C out/Default I can build predefined static libs but I have not found a way how to use gn or ninja to generate the shared libraries. 回答1: After running gn gen out\Default , you can edit the out\Default\toolchain.ninja file to add extra compiler flags to the command for the cc and cxx rules
