Update Google Breakpad

[koxu1996]

This PR updates Google Breakpad to the latest version.

It should close ARM related issues: #303, #310, #456.

---

You can reproduce all changes with the following steps:

1. Prepare breakpad

$ git clone https://github.com/google/breakpad.git /tmp/breakpad
$ cd /tmp/breakpad
$ git checkout 3ea3af4

2. Prepare lss

$ git clone https://chromium.googlesource.com/linux-syscall-support /tmp/lss
$ cd /tmp/lss
$ git checkout 9719c1e

3. Clone MEGAsync repository

$ git clone --recursive https://github.com/meganz/MEGAsync.git /tmp/megasync
$ cd /tmp/megasync
$ git checkout c422ca2

4. Update breakpad files - 2751244

$ rm -r ./src/MEGASync/google_breakpad/client
$ cp -r /tmp/breakpad/src/client ./src/MEGASync/google_breakpad/client

$ rm -r ./src/MEGASync/google_breakpad/common
$ cp -r /tmp/breakpad/src/common ./src/MEGASync/google_breakpad/common

$ rm -r ./src/MEGASync/google_breakpad/google_breakpad
$ cp -r /tmp/breakpad/src/google_breakpad ./src/MEGASync/google_breakpad/google_breakpad

$ rm ./src/MEGASync/google_breakpad/third_party/lss/linux_syscall_support.h
$ cp /tmp/lss/linux_syscall_support.h ./src/MEGASync/google_breakpad/third_party/lss/linux_syscall_support.h

$ sed -ie "s/convert_UTF.c/convert_UTF.cc/g" ./src/MEGASync/google_breakpad/google_breakpad.pri

$ git add . && git commit -m "Update google breakpad to 3ea3af4"

5. Apply workaround for inttypes.h has already been included before this header file, but without __STDC_FORMAT_MACROS defined error - fbbe423

$ sed -i '44s|^|//|' ./src/MEGASync/google_breakpad/google_breakpad/common/breakpad_types.h
$ sed -i '45s|^|//|' ./src/MEGASync/google_breakpad/google_breakpad/common/breakpad_types.h

$ git add . && git commit -m "Workaround for inttypes.h error"

I am not sure about this step, maybe __STDC_FORMAT_MACROS should be defined somewhere in megasync SDK 🤔

I was getting unresolved reference error:

/usr/bin/ld: minidump_writer.o: in function `(anonymous namespace)::MinidumpWriter::FillRawModule(google_breakpad::MappingInfo const&, bool, unsigned int, MDRawModule*, unsigned char const*)':
/tmp/MEGAsync/src/MEGASync/google_breakpad/client/linux/minidump_writer/minidump_writer.cc:651: undefined reference to `google_breakpad::PEFile::TryGetDebugInfo(char const*, google_breakpad::_RSDS_DEBUG_FORMAT*)'

It was just matter of inculding new pe_file.cc in qmake - 588101d:

Note, I also had some issues with freeimage library and its neon optimizations. I found out they should be disabled for ARM, however it seems to be already done in mega's SDK:

    # freeimage's LibPNG has a problem with deciding to use neon on 64 bit arm, resulting in a missing symbol
    if [ "$ARCH" == "aarch64" -o "$ARCH" == "arm64" ]; then
        export CFLAGS="$CFLAGS -DPNG_ARM_NEON_OPT=0"
    fi 

---

With that I was able to build everything:

$ cd /tmp/megasync/src/
$ ./configure -g -q -i
$ qmake MEGASync/MEGASync.pro
$ lrelease MEGASync/MEGASync.pro
$ make

It works on Asahi Linux with M2 ❤️

I am sharing compiled binary with you: megasync_v4.9.3_aarch64, virus total scan here.

[farid220]

Hi
Thanks for your concern about fixing this problem.
I'm using aarch64 and I want to compile it.
I encounterd the breakpad issue and I tried your solotuion step by step.
But now I get the following error while compiling.

I'd appreciate it if you could take a look and help.

Despite following the provided steps I was not able to build on a up to date install of asahi linux due to the breakpad issue.
This alternative removes the crashhandler to allow working builds and runs great on asahi:
