Problems with XCB/X11 when building

[EwanRoycroft]

I'm trying to build Chromium v74 from source, implementing the MMAL patch, and received the following error when building:

ninja: Entering directory `out/Release_GN_arm'

ld.lld: error: unable to find library -lxcb-image
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I copied libxcb-image.so from the RPi4 and placed it in ./build/linux/debian_sid_arm-sysroot/lib/arm-linux-gnueabihf/; which seemed to work, and ninja carried on compiling.

I then received the following errors relating to one of the files created by v74.0.3729.182_mmal_3_22.patch:

What might be causing these errors? Am I missing more dependencies from the sysroot?

[XECDesign]

This repo is for the packaging only, I can't provide general build support. All I can say is that I was able to get it to cross-compile using the instructions included in the patch a long time ago, before I switched to native builds.

[EwanRoycroft]

How long does native compiling take? Must be pretty intensive given the recommended system requirements for building Chromium.

I opened a topic on the forums the other day looking for up-to-date instructions for building/patching Chromium. Do you know of any? Is this something that might be released with the new v78?

[XECDesign]

It took 2 days on an 8 core 2.4GHz ARM server. You'll run out of RAM trying to do it on a pi unless you use the 64bit kernel and some swap. Needless to say it will take even longer.
