This fix is based on a problem with cxx_compiler and cxx_linker macros on Windows. There was an issue with compiler detection in paths containing "icc". In such case, Makefile.rules thought it was provided with icc compiler. To solve that, utilities detection has been rewritten in Python. The last element of compiler's path is separated, taking into account the platform path delimiter, and compiler type is extracted, with regard of possible cross-toolchain prefix. --------- Co-authored-by: Pavel Labath <pavel@labath.sk>

# 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 against 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.
