libarchive @3.2.1 - Build failure

[iefdev (Eric F)]

A new version of libarchive(@3.2.1) arrived last night when I ran the update…

But, the build fails. Did try to clean->reinstall etc. I have no idea how to solve this.

Last part of: sudo port -v -s upgrade libarchive (from 1st error)

Uhhhhhh

[tobypeterson]

Here's the check, which is apparently wrong for your compiler:

#if defined(_MSC_VER) && _MSC_VER >= 1400  /* Visual Studio */
#  define bswap16(x) _byteswap_ushort(x)
#elif (defined(__GNUC__) && __GNUC__ >= 4 && __GNUC_MINOR__ >= 8) \
      || defined(__clang__)
#  define bswap16(x) __builtin_bswap16(x)
#else
#  define bswap16(x) ((((x) >> 8) & 0xff) | ((x) << 8))
#endif

If you can provide the output of the following command, I might be able to help:

cc -E -dM -xc /dev/null

[iEFdev]

Thanks for you reply…

I have GCC @5.4.0 installed to, so cc alone in Terminal would reflect to that one. And when using sudo port ... it's using the Apple bundled version, right? The error in the first post also list /usr/bin/clang

So, I ran the command on both.

_See attachment “cc_test.txt”_

[iEFdev]

Terminal output of cc

[tobypeterson]

So it probably needs a more specific clang version check. I'll try to figure out when builtin_bswap16 was added.

[tobypeterson]

Or could use has_builtin(builtin_bswap16) if that's supported on that clang version

Cc Me!

Also 10.7.5

Thank you! 👍 Installation went fine.
