Status: RESOLVED DUPLICATE of bug 634763

(SeaMonkey :: Build Config, defect)

Description

[David Kredba]

Attachment: build.log.gz

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0 SeaMonkey/2.22.1 (Beta/Release)
Build ID: 20131113180422

Steps to reproduce:

With snapshot of gcc-4.9.0-20131208 I tried to build Seamonkey on Gentoo with LTO enabled. I had to disable elf hack, include string.h in BufferUnrotate.cpp and it was compiling fine until undefined references around JS. 

See the build.log attached gzipped.

What I can test please?

Comment 1

[David Kredba]

Without LTO and with disabled Enigmail with the same CFLAGS and included string.h it builds fine. Iwould like to use LTO.

Comment 2

[Philip Chee]

Did you try a CLOBBER build? That is delete your object directory and then do a full build (e.g. make configure build)

Comment 3

[David Kredba]

I am always rebuilding, no ccache or similar.

What at GCC told me is that gcc-4.9.0 uses not in binutils supported LTO object format (lto plugin in binutils is needed), so patch for binutils or AR=ar-gcc AS=gcc-as NM=gcc-nm and RANLIB=gcc-ranlib is needed. It helped me with Mesa and Openldap but not with Seamoneky-2.23.

But the error is now more clear:

Building with LTO is not a supported configuration for building SeaMonkey. I suggest that you inquire futher on IRC.

irc://moznet/developers
or
irc://moznet/build

(Bug 634763 comment #0) [ PrepareAndDispatch is only referenced from inline assembly]

Bug 634763 is WONTFIX. Workaround is to use LLVM to do PGO builds.
