Status: RESOLVED DUPLICATE of bug 638056

(Core :: JavaScript Engine, defect)

Description

[sean o'connor]

User-Agent:       Mozilla/5.0 (compatible; Konqueror/4.4; Linux) KHTML/4.4.5 (like Gecko)
Build Identifier: hg pull -r default

mozilla-central/js/src/assembler/jit/ExecutableAllocator.h:379:6: error: #error "The cacheFlush support is missing on this platform."

Reproducible: Always

Steps to Reproduce:
1. get sources via mercurial from mozilla
2. create mozconfig as per instructions on developer.mozilla.org/en/build_documentation
3. start the build.
4. i've tried this with mercurial pulls for about two weeks now and so far every time it renders the error:

mozilla-central/js/src/assembler/jit/ExecutableAllocator.h:379:6: error: #error "The cacheFlush support is missing on this platform."

I've googled around for a fix, but it seems to be a lil' rare.  PPC64/Linux rare? go figure.
Actual Results:  
Cannot build.

Expected Results:  
Built Firefox 4 beta!!!!

This is on a dual-cpu G5 ppc(64) Debian Linux box.  3gh RAM.

You will have to write the necessary code to support PPC64, since it does not already exist. You could also --disable-jit, I think, although the build will then run JS much more slowly!
