Having problems compiling context free on os x. I'm not using xcode, just the command line. libpng is installed.

---------
MacBookPro running 10.6, 64bit intel.

Polymanos:ContextFreeSource2.2.2 seant$ make
cc -Isrc-common -Isrc-unix -Iobjs -Isrc-agg/include -Isrc-common/agg-extras -O3 -Wall -c -o objs/lex.yy.o objs/lex.yy.c
<stdout>:856: error: conflicting types for ‘yyget_leng’
src-common/yglue.h:54: error: previous declaration of ‘yyget_leng’ was here
<stdout>:2291: error: conflicting types for ‘yyget_leng’
src-common/yglue.h:54: error: previous declaration of ‘yyget_leng’ was here
make: *** [objs/lex.yy.o] Error 1
---------

Any help?

Maybe you are running a different version of flex or yacc than the standard ones that are installed with OSX 10.6. Find out what version of flex and yacc you have:

Code: Select all

[570] : flex -V
flex 2.5.35

john@John-Horigans-MacBook-Pro   ~/Projects/CF2.2
[571] : yacc -V
bison (GNU Bison) 2.3

It seems that lines 51 through 61 of yglue.h are superfluous. Try commenting them out.

Same error on 64-bit linux, bison 2.4.2, flex 2.5.35

I went for the cheapest fix and changed the type at src-common/yglue.h:54 from size_t to int.

Ah good. I can stop worrying about side-effects.
