No Info.plist?

Do I need one?

That name’s kinda redundant, no? Following the example in Chrome, I’d expect the
name to have something to do with “framework”, and the Info.plist to be
framework-Info.plist, to disambiguate from the names that have to do with the
app or other bundles or linker output.

I don’t think that this is even necessary now that you’re using
__attribute__((visibility("default"))).

In this file:

#if defined(OS_MACOSX)
__attribute__((visibility("default")))
int main(int argc, const char* argv[]) {
#else
int main(int argc, const char** argv) {
#endif  // OS_MACOSX

1. The “const” is technically illegal, and

2. There’s no reason that non-OS_MACOSX can’t use “char* argv[]” like the
OS_MACOSX branch.

As I will mention elsewhere, exposing the delegate from the framework seems kind
of unclean to me. I think that the best approach would be to allow ContentMain
to accept a NULL delegate; in the case of a NULL delegate passed in, it should
use its own built-in ContentShellDelegate as the default. This will eliminate
the need to pass the default delegate in and therefore eliminate the need to
export these extra symbols.

[Avi (use Gerrit), 2012/02/29 19:46:50]

Simplified.
Now that we have shell_browser_main, we can do that there. Otherwise it would be
a gross layering violation.

It’d be nice to run tweak_info_plist just to get the SVN keys set. Some things
in base that do version number lookups actually care about that. You’d run
tweak_info_plist with -s1 and the other things false.

[Mark Mentovai, 2012/02/28 20:12:40]

The “verify” build step from chrome_exe would be very nice to have here. There
should be no Objective-C in the main executable. See bug 88697.
