Bug 119373 – webkit-gtk fails to build with bison-3.0

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Jeremy Huddleston Sequoia]

Reported at https://trac.macports.org/ticket/39923

When using the recently released bison-3.0, webkit-gtk fails to build:

:info:build DerivedSources/ANGLE/glslang_tab.cpp:1785:16: error: no matching function for call to 'yylex'
:info:build       yychar = yylex (&yylval);
:info:build                ^~~~~
:info:build DerivedSources/ANGLE/glslang_tab.cpp:279:12: note: candidate function not viable: requires 2 arguments, but 1 was provided
:info:build extern int yylex(YYSTYPE* yylval_param, void* yyscanner);

Confirmed.

There are already generated glslang_tab.cpp and glslang_tab.h files in the ANGLE directory, produced by Bison 2.7[1].
The third-party sources have these two files regenerated with Bison 2.3, for Mac port's purposes.
The GTK port regenerates these with the Bison it finds during the configuration. With Bison 3.0, the generated files are causing compilation errors. Could the GTK port switch to building the files that were generated with Bison 2.3, just like the Mac port?

Also, only the GTK port generates and compiles the glslang.cpp file, so this part could possibly be removed.

I patched glslang.y for bison 3 in bug #119798 so after landing that you might be able to revert this patch.

Do you perhaps plan to upstream the fix into ANGLE itself?
And thanks for the notice.

I wasn't planning on upstreaming it, but I will take a look now. I was just trying to fix the Qt build in the cleanest possible way.

Re-opened since this is blocked by bug 119892

[Zan Dobersek]

The revision was merged into the webkit-2.0 branch, but should stay there as the ANGLE third-party source has been updated since the branching, so merging the source generation fix into the branch would be a bit risky.

Closing again.
