Bug 88407 – WebKit-GTK 1.8.1 does not build on OS X 10.7

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Timo Dörr]

Latest WebKit-GTK 1.8.1 (maybe earlier versions, too) does not build on OS X 10.7 Lion.

The error message I get is:

   + make -j2
  GEN    DerivedSources/WebCore/idl_supplemental_dependencies

  GEN    DerivedSources/webkit/webkitdomdefines.h

Can't call method "fileName" without a package or object reference at Source/WebCore/bindings/scripts/IDLParser.pm line 112.
make: *** [DerivedSources/WebCore/idl_supplemental_dependencies] Error 1
 

I've found via google that someone else already had the same error and posted it at the webkit-help mailinglist, but without responses: http://lists.webkit.org/pipermail/webkit-help/2012-March/003025.html
 
Here are the parameters I used with the configure script:
 
./configure --prefix="/Users/td/banshee-dev/bockbuild/profiles/banshee/build-root/_install" --disable-video --disable-geolocation --disable-xslt --with-target=quartz --with-gtk=2.0 --disable-gtk-doc
 
and the configure report:

I have also tried to use clang as a compiler, which gives a very similar error:
$ make
  GEN    DerivedSources/WebCore/idl_supplemental_dependencies
clang: error: no input files

I've been hitting this as well in trying to update MacPorts' webkit-gtk.  We've been stuck at 1.6.3 because of this issue...

[Jeremy Huddleston Sequoia]

Here's the actual command that is used to generate idl_supplemental_dependencies, with an extra --verbose:

~/src/macports/dports/www/webkit-gtk/work/webkit-1.8.2 $ /opt/local/bin/perl -I./Source/WebCore/bindings/scripts ./Source/WebCore/bindings/scripts/resolve-supplemental.pl --defines "LANGUAGE_JAVASCRIPT=1 ENABLE_CHANNEL_MESSAGING=1   ENABLE_METER_TAG=1 ENABLE_PROGRESS_TAG=1 ENABLE_JAVASCRIPT_DEBUGGER=1  ENABLE_SQL_DATABASE=1 ENABLE_DATALIST=1            ENABLE_VIDEO=1   ENABLE_FULLSCREEN_API=1   ENABLE_XSLT=1 ENABLE_WORKERS=1 ENABLE_SHADOW_DOM=1 ENABLE_SHARED_WORKERS=1 ENABLE_FILTERS=1 ENABLE_GEOLOCATION=1 ENABLE_CLIENT_BASED_GEOLOCATION=1 ENABLE_MATHML=1  ENABLE_SVG=1 ENABLE_SVG_FONTS=1  ENABLE_WEB_SOCKETS=1 ENABLE_BLOB=1  ENABLE_REQUEST_ANIMATION_FRAME=1 ENABLE_WEBGL=1     " --idlFilesList ./DerivedSources/WebCore/idl_files_list --supplementalDependencyFile DerivedSources/WebCore/idl_supplemental_dependencies --verbose

---

That "Starting to parse" line comes from:
print " | *** Starting to parse $fileName...\n |\n" unless $beQuiet;

which shows that $fileName is being set to "-n" for some reason...

---

And here's why:

 $ head ./DerivedSources/WebCore/idl_files_list
-n
./Source/WebCore/css/CSSCharsetRule.idl
./Source/WebCore/css/CSSFontFaceRule.idl
./Source/WebCore/css/CSSImportRule.idl
./Source/WebCore/css/CSSMediaRule.idl
./Source/WebCore/css/CSSPageRule.idl
./Source/WebCore/css/CSSPrimitiveValue.idl
./Source/WebCore/css/CSSRule.idl
./Source/WebCore/css/CSSRuleList.idl
./Source/WebCore/css/CSSStyleDeclaration.idl

[Jeremy Huddleston Sequoia]

Which comes from:

webkit-1.8.2 $ sudo make V=1
echo -n > ./DerivedSources/WebCore/idl_files_list
...

Workaround is to use /bin/echo rather than the shell's builtin.  If /bin/sh is the shell being used by make, then "echo -n" will simply echo "-n" ...

sed -i 's:echo -n:/bin/echo -n:g' GNUmakefile{.in,}

[Jeremy Huddleston Sequoia]

And it looks like the ultimate source of the issue is with Source/WebCore/GNUmakefile.am

[Philippe Normand]

The first echo -n:

	$(AM_V_at)echo -n > $(idl_files_list)

can be replaced by:

        >$(idl_files_list)

And for:

        $(AM_V_at)($(foreach idl, $(dom_binding_idls), echo $(idl) &&) echo -n) >> $(idl_files_list)

Hum, not sure. My shell programming skills are rusty :) Is that echo -n call really needed?

That's because you need a final command after the last &&.

I think we can replace 'echo -n' with 'true' or ':'.
