 |
|
Hello,
I've been looking at www-client/chromium-72.0.3626.28-r1 on arm64 over the last few days. Had to patch the main tree ebuild and source a little bit to get it to build: here are the details in case it is of use to anyone else.
First, I had to modify the ebuild (bumped it to -r2 in the overlay used by the gentoo-on-rpi3-64bit project), because:
- I experienced multiple build failures under gcc-8.2.0; so set CHROMIUM_FORCE_CLANG=yes;
- however, building under Clang/LLVM, I had to enable an additional keeplib (specifically, third_party/swiftshader/third_party/llvm-7.0);
- more for my use case than of general interest, but I needed to omit the unconditional media-libs/openh264 DEPEND (as that package has RESTRICT="bindist", and I need everything to get pushed up to a binhost); so, added a USE flag to control this;
Here's a diff between the main-tree r1 and the modified r2 ebuild, showing these changes: | Code: | --- chromium-72.0.3626.28-r1.ebuild

(NB the rpi3-overlay repo where this ebuild lives is only for use with the arm64 RPi3; some of the above changes should probably be keyword-specific, were the ebuild to be used more generally)
Second, to allow third-party/crashpad to build, I had to patch one of its files slightly (which was missing a #include); here's the (trivial) chromium-crashpad.patch, to place in the www-client/chromium/files/ directory (as you can see above, its path has been added to PATCHES in the -r2 ebuild):

The resulting binary package is available from the isshoni.org binhost, here. Seems to work OK in basic testing on an RPi3B+.
Users of (a reasonably up-to-date version of) the gentoo-on-rpi3-64bit image may get this simply by issuing: | Code: | demouser@pi64 ~ $ sudo emaint sync --repo rpi3
demouser@pi64 ~ $ emerge -avu www-client/chromium |
