[cfe-dev] CSCommon.h fails to compile (Mac OS X 10.11)

Mon Nov 30 08:47:35 PST 2015

Sorry, I have no idea how that works.  There ought to be some way to control the diagnostics, I just don't know how.

Thanks! Does this still apply if I'm just using the clang API? I don't currently pass any CLI-esk string arguments to clang anywhere (that I know of).

It's a warning that's set to be treated as an error by default (as –Werror=c++11-narrowing).
On Linux I can use –Wno-c++11-narrowing and it gets rid of the error.  If you want it to be a warning instead of an error you can say –Wno-error=c++11-narrowing instead.

Thanks!

It comes through as an error rather than a warning though, so we can't simply ignore / disable it.

The diagnostic probably said [-Wc++11-narrowing] so try –Wno-c++11-narrowing.  Better to get the header fixed, though:

A bug in the header, which you could report to Apple.  That should be '1u << 31' given that the base type is uint32_t.

Hello folks,

I'm working on a project that uses clang and it seems that I cannot compile the CSCommon.h header inside the Apple SDKs. The error I get is:

enumerator value evaluates to -2147483648<tel:2147483648>, which cannot be narrowed to type uint32_t (aka unsingned int)

Around the source code:
typedef CF_OPTIONS(uint32_t, SecCSFlags) {
    kSecCSDefaultFlags = 0, /* no particular flags (default behavior) */

    kSecCSConsiderExpiration = 1 << 31, /* consider expired certificates invalid */
    kSecCSEnforceRevocationChecks = 1 << 30, /* force revocation checks regardless of preference settings */
    kSecCSNoNetworkAccess = 1 << 29,            /* do not use the network, cancels "kSecCSEnforceRevocationChecks"  */
    kSecCSReportProgress = 1 << 28, /* make progress report call-backs when configured */
    kSecCSCheckTrustedAnchors = 1 << 27, /* build certificate chain to system trust anchors, not to any self-signed certificate */
};

clang revision 253884

Previously, we just hacked around this with:

#undef CF_OPTIONS
#define CF_OPTIONS(_type, _name) _type _name; enum

But alas some of our users are still reporting the error.

Has anyone encountered this before? Is there a specific LangOpt I need to set?

Many thanks in advance.
