| # This makefile aims to make the binaries as small as possible, for us not to |
| # upload huge binary blobs in the repo. |
| # The binary should have debug symbols because stack unwinding doesn't work |
| # correctly using the information in the Minidump only. Also we want to evaluate |
| # local variables, etc. |
| # Breakpad compiles as a static library, so statically linking againts it |
| # makes the binary huge. |
| # Dynamically linking to it does improve things, but we are still #include-ing |
| # breakpad headers (which is a lot of source code for which we generate debug |
| # symbols) |
| # So, install_breakpad.cpp does the #include-ing and defines a global function |
| # "InstallBreakpad" that does all the exception handler registration. |
| # We compile install_breakpad to object file and then link it, alongside the |
| # static libbreakpad, into a shared library. |
| # Then the binaries dynamically link to that lib. |
| # The other optimisation is not using the standard library (hence the _start |
| # instead of main). We only link dynamically to some standard libraries. |
| # This way we have a tiny binary (~8K) that has debug symbols and uses breakpad |
| # to generate a Minidump when the binary crashes/requests such. |
