[metapost] Compilation of MetaPost from SVN, release 181, on Mac OS X

[Peter Dyballa]

Hello!

A Mac OS X user has asked me to compile MetaPost for the PPC  
architecture. During compilation these warnings are emitted:

	In file included from ./cwebdir/comm-w2c.ch:153:
or
	In file included from ../../../src/texk/web2c/tiedir/tie-w2c.ch:34:
+
	../../../src/texk/web2c/cpascal.h:50:1: warning: "floor" redefined
	In file included from /usr/include/math.h:26,
	                 from ../../../src/texk/web2c/../kpathsea/c-std.h:31,
	                 from ../../../src/texk/web2c/../kpathsea/config.h:82,
	                 from ../../../src/texk/web2c/config.h:44,
	                 from ../../../src/texk/web2c/cpascal.h:16,
	                 from ./cwebdir/comm-w2c.ch:153:
	/usr/include/architecture/ppc/math.h:853:1: warning: this is the  
location of the previous definition

The #define in Apple's /usr/include/architecture/ppc/math.h file is  
inside a #if defined(__FAST_MATH__) && !defined(__cplusplus) clause,  
so it might be appropriate to use

	#if !defined(__FAST_MATH__)	/* Mac OS X and probably other OS */
	#define floor(x)	((integer)floor((double)(x)))
	#endif

Compilation ends prematurely at:

	make[1]: `web2c' is up to date.
	srcdir=../../../src/texk/web2c /bin/sh ../../../src/texk/web2c/web2c/

	make: *** [tangleboot.c] Error 1


The problem is that convert is not receiving for $native the correct  
value.  build/texk/web2c/Makefile has set:

	native = /texk/web2c

In build/texk/web2c/config.log I can see:

	<stdin>:3: error: conflicting types for 'yytext'
	configure:1804: error: previous declaration of 'yytext' was here
	configure: failed program was:
	#line 1415 "configure"

plus failures when checking for ldnet or ldent_stub, but that's OK  
here. In Makefile these values are set:

	native = /texk/web2c
	target = NONE
	host  = NONE

Setting native to ``.´´ leads to different errors:

	srcdir=../../../src/texk/web2c /bin/sh ../../../src/texk/web2c/web2c/ 
convert . tex
	parse error: Last token = 59 (;), error buffer = `;',
		last id = `getjobname' (function with parameters).
