Re: [sqlite] OS X/Xcode build error: use of unknown builtin

2017-02-15 Thread Anthony Chan (antchan2) 
Thank you for all the responses and a speedy resolution.  For complete-ness: I 
am using the older Xcode 6.4 – “Apple LLVM version 6.1.0 (clang-602.0.53) 
(based on LLVM 3.6.0svn)”.  

Now that the problem has been fixed in 3.17 branch I will use that.

Several possible fixes, any one of which will work:

(1) Update your Xcode to the latest from Apple

(2) Compile using the -DSQLITE_DISABLE_INTRINSIC compile-time option

(3) Use the latest SQLite code from trunk
(https://www.sqlite.org/src/info/trunk) or from branch-3.17
(https://www.sqlite.org/src/info/branch-3.17).  Click on one of the
"Tarball" or "ZIP Archive" links to download the complete source code.

(4) Apply the patch shown at
https://www.sqlite.org/src/vpatch?from=ada05cfa86ad7f56=8d3f485d86b2f2d8

What does "clang -v" show on your machine?

Hello Anthony !

I also got those errors and did a dirty change to sqlite3 to compile, 
your proposal makes an all or nothing use of builtins, probably a one by 
one check/enable could give better result.


Cheers !

(http://www.sqlite.org/src/info/798fb9d70d2e5f95) and the use of CLANG_VERSION

According to Clang documentation

With this in mind, I suggest creating a new macro that uses feature checking

# if __has_builtin(__builtin_add_overflow) && \

We do test extensively on OSX and didn't have any problems.  What
version of Xcode do you have?

[sqlite] OS X/Xcode build error: use of unknown builtin

I believe this is related to the recent change “Cleanup the usage of the 
SQLITE_DISABLE_INTRINSIC compile-time option…” 
(http://www.sqlite.org/src/info/798fb9d70d2e5f95) and the use of CLANG_VERSION 
to decide whether to use builtin functions:

#if defined(__clang__) && !defined(_WIN32) && !defined(SQLITE_DISABLE_INTRINSIC)
# define CLANG_VERSION \
(__clang_major__*100+__clang_minor__*1000+__clang_patchlevel__)

  return __builtin_bswap32(x);

According to Clang documentation 
(http://clang.llvm.org/docs/LanguageExtensions.html): “marketing version 
numbers should not be used to check for language features, as different vendors 
use different numbering schemes. Instead, use the Feature Checking Macros.”

With this in mind, I suggest creating a new macro that uses feature checking

# if __has_builtin(__builtin_add_overflow) && \

#  define CLANG_USE_INTRINSIC 1
# else 
#  define CLANG_USE_INTRINSIC 0

#else
# define CLANG_USE_INTRINSIC 0
#endif

The tests would look like this:

#elif SQLITE_BYTEORDER==1234 && (GCC_VERSION>=4003000 || CLANG_USE_INTRINSIC!=0)
