QtWebEngine 6.2.2 compilation failure

[therealmatiss]

Hello! I'm trying to compile QtWebEngine 6.2.2 submodule on Nvidia Jetson TX2 natively. I went through the configuration process just fine, this is my config command:

cd $MODULE_PATH
/usr/local/qt/bin/qt-configure-module . -feature-webengine-embedded-build

When I am building with cmake --build . --parallel 6, I get this error:

-- GN Done. Made 16019 targets from 2327 files in 22728ms

I don't see the code issue on the file src/3rdparty/chromium/third_party/skia/src/opts/SkOpts_crc32.cpp

#include "src/core/SkOpts.h"

#define SK_OPTS_NS crc32
#include "src/opts/SkChecksum_opts.h"

namespace SkOpts {
    void Init_crc32() {
        hash_fn = crc32::hash_fn;
    }
}

What can I do here? Am I using wrong compilers? I tried gcc-9 as well. This is my configuration output:
