Bug 16850 – merged autotools and derivedssources.make

• Component: WebKitGTK
• Status: RESOLVED WONTFIX

[Jan Alonzo]

The attached patch reuses DerivedSources.make as well as enabling -fvisibility-hidden and -fvisibility-inlines-hidden. We can't do this without a symbols defs file so the patch merges JSC into libWebKitGtk for the mean time. 

Cheers

We need to backport our fixes to DerivedSources.make, replace perl/flex/bison commands with $(PERL) etc. and elminate the global vpath in DerivedSources.make first.

We should only look at changing the GNUmakefile.ams only after that's done I think, otherwise we'll re-introduce all the regressions we fixed like make -j support.

Hi alp! what do you mean by eliminating the global vpath?

Thanks

WebCore/DerivedSources.make has:

VPATH = \
    $(WebCore) \
    $(WebCore)/bindings/js \
    $(WebCore)/bindings/objc \
    $(WebCore)/css \
    $(WebCore)/dom \
    $(WebCore)/html \
    $(WebCore)/page \
    $(WebCore)/storage \
    $(WebCore)/xml \
    $(WebCore)/svg

This modifies the global make search path -- not good.

Somewhat better:

vpath %.idl = \
    $(WebCore) \
    $(WebCore)/bindings/js \
    $(WebCore)/bindings/objc \
    $(WebCore)/css \
    $(WebCore)/dom \
    $(WebCore)/html \
    $(WebCore)/page \
    $(WebCore)/storage \
    $(WebCore)/svg \
    $(WebCore)/xml

Why not just:
DocTypeStrings.cpp : $(WebCore)/html/DocTypeStrings.gperf
	$(GPERF) -CEot -L ANSI-C -k "*" -N findDoctypeEntry -F ,PubIDInfo::eAlmostStandards,PubIDInfo::eAlmostStandards $< > $@

Ditto.

Alp, you're right. I got confused with the changes when backporting it to DerivedSources.make. Feel free to make the change.

Cheers.

DerivedSources.make improvements and backported fixes

I suspect the $(WebCore) changes will not actually be necessary when we include the DerivedSources.make files (but can't be sure till we try to do it). The other changes look good, except for my previous comments.

Updated patch to reuse DerivedSources.make

As discussed on IRC this isn't the right way to do things. I've enabled -fvisibility=hidden and -fvisibility-inlines-hidden using libtool modules in r29445.

We should aim to include DerivedSources.make, not invoke the make application on it, as this would lose any benefits of integrating the two.

Clearing request flag since there are issues present and the patch doesn't apply any more.

Jan, I'll take care of splitting this up and getting things fixed. Thanks for the initial patch.
