I'm trying to emege firefox on the stable branch and it keeps failing with the following error in the build.log (apologies for the broken encoding):

Code:

Here's my make.conf:

# detailed example.

I'm also using the gold linker.

And here's the full build.log: https://pastebin.com/yRSspraq

Any help would be appreciated, thanks.

Hi,

is there a special reason to compile the Firefox. You could use the www-client/firefox-bin package instead.

Regards

That's quite the opposite of what he is doing here.
firefox-bin is more for low powered systems and is compiled to run on most systems.

What OP is doing is optimizing Firefox (otherwise he would not compile, let alone with LTO, which is nothing _but_ optimization)

Mozilla provided binaries in firefox-bin are built with LTO too, and I believe also PGO.
