Issues compiling Veracrypt on Mac OS X El Capitan 10.11.5

Question

I'm having issues compiling Veracrypt on El Capitan

This is the error I get:

../Crypto/Whirlpool.c:511:3: error: unknown token in expression
                KSH(2, 3, 2, 1, 0, 7)
                ^

      ^

Here is my gcc info:

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

This compiles fine on Ubuntu 16.04. Not sure what i need to do. I've install all the required software and I've even tried two higher versions of gcc.

Based on where the ^ is located, %r10 is an "unknown token"? That only seems possible if (somehow) you were compiling for 32bit. Or perhaps the caret is in the wrong place and it's the mm1 it doesn't recognize? — David Wohlferd, Sep 21 '16 at 22:18

The inline code for the nasm assembler is not correctly expanded, see also this issue in veracrypt repository. The culprits are located in cpu.h (lines 259 until 263 in the 1.19 release). You can try to substitute these with

#define GNU_AS1(x) #x ";"
#define GNU_AS2(x, y) #x ", " #y ";"
#define GNU_AS3(x, y, z) #x ", " #y ", " #z ";"
#define GNU_ASL(x) "\n\t#x:"
#define GNU_ASJ(x, y, z) #x " " #y #z ";"

but it could be that in the final test for encryption you will get an error for TestPkcs5.

Addendum 2017-06-08: The latest git clone of veracrypt compiles without problems, the inline assembly in the whirlpool hashing function is disabled now.
