Bug 118887 – WebKitExports.def.in needs 64-bit symbols

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Alex Christensen]

WebKitExports.def.in contains many Visual Studio compiler symbols that are exported by WebKit.  Most of them contain pointers, which change size when compiling for x86_64 architecture, and they require a separate symbol.  They should be next to each other for easy maintenance.

We are getting a compile failure when we attempt to compile the output of this macro (as processed by the build script).  Take a look at the intermediary output: WebKitExports.def.in gets converted to $(WebKitOutput)\obj(32|64)\WebKitExportGenerator\DerivedSources\WebKitExportsGenerator.cpp.  This is processed by the compiler as a series of 'printf' statements.  Somehow, the trailing end of the symbol is getting appended with a ")'".

Here's the specific error:

     1>C:\cygwin\home\buildbot\WebKit\WebKitBuild\Release\obj32\WebKitExportGenerator\WebKitExports.def(108): fatal error LNK1118: syntax error in '?fastMalloc@WTF@@YAPEAX_K@Z)' statement

Build FAILED.
