Problem compiling on MacOS

[glocq]

Trying to compile on MacOS High Sierra 10.13.6 using make results in an error:

In file included from Standalone/synth.c:41:
Misc/common.h:70:6: error: conflicting types for 'swab'
void swab( const char *from, char *to, int nbytes);
     ^
/usr/include/unistd.h:600:10: note: previous declaration is here
void     swab(const void * __restrict, void * __restrict, ssize_t);
         ^

I did uncomment CFLAGS += -DTARGET_OS_MAC as specified in README_Makefile.md.

Strange - chengdu was able to compile mbrola on MacOS 64 Bit (see #3 (comment)_ )

1. The cause of the warning is that the swab function is defined twice.
   What happens if you comment out the swab function in Misc/common.h?
   Do you still get the compile error?
2. I checked the parts of the code where the compiler directive TARGET_OS_MAC is
   used. It's only reason is to enable the swab-function. So simply commenting the CFLAGS
   line out - again - should do the job.

No, it's going through 🎉

No, I didn't comment it out otherwise I get an error in common.c

A bit frustrated, I tried to compile the project under Multipass with Ubuntu Linux on MacOS.

I was able to compile following the documentation and was also able to create my first wave file.

$ Bin/mbrola -i ../MBROLA-voices/data/ca1/ca1 \
                          ../MBROLA-voices/data/ca1/test/merci.pho merci.wav

I then copied the file back onto the Mac

% sudo scp -i /var/root/Library/Application\ Support/multipassd/ssh-keys/id_rsa \
             multipass@192.168.64.4:MBROLA/merci.wav .

And it played only with Audacity and Garage Band but iTunes Music coudn't play the sound file, same noise issue.

Great projet! 🎉
