• Component: WebCore Misc.

[Daniel Macks]

Compiling webkit source (nightly r35788) on OS X 10.4, using all gtk and other non-apple-supplied support libs using latest available from fink unstable tree...

1. ./autogen.sh --prefix=/sw --with-target=x11 --with-http-backend=curl --with-font-backend-pango --disable-video

no configure problems...Build configuration reports "HTTP backend: curl"

2. make

I think SIZE_MAX is in stdint.h; will test

[Daniel Macks]

FormDataStreamCurl.cpp tries to get stdint.h:

#include "config.h"
// We need to define __STDC_LIMIT_MACROS to define SIZE_MAX.
#ifndef __STDC_LIMIT_MACROS
#define __STDC_LIMIT_MACROS
#include <stdint.h>
#undef __STDC_LIMIT_MACROS
#else
#include <stdint.h>
#endif

but tracing the #include jungle, it looks like that's too late, as stdint.h has already been loaded...

In file included from /usr/include/sys/_endian.h:88,
                 from /usr/include/ppc/endian.h:107,
                 from /usr/include/machine/endian.h:30,
                 from /usr/include/sys/wait.h:182,
                 from /usr/include/stdlib.h:64,
                 from ./JavaScriptCore/wtf/FastMalloc.h:25,
                 from ./WebCore/config.h:77,
                 from WebCore/platform/network/curl/FormDataStreamCurl.cpp:30

Moving the config.h *after* stdint.h solves it for me (and makes some sense...load all the system headers before webkit's own stuff. Not sure if that affects win32, which may do headers differently and/or need local overrides of standard-on-unix stuff.

[Mark Rowe (bdash)]

It's probably a lot more portable, and definitely cleaner, to use std::numeric_limits<size_t>::max() instead.

[Daniel Macks]

Using that instead of SIZE_MAX (and scrapping the whole stdint.h block entirely) allows building with no warnings or undefined symbols.
