For some research work I’m doing, I would like to do some Bayesian modeling for text categorization. Since I’m not interested in re-inventing wheels when there are plenty of very well constructed wheels available for the taking, I thought I would install Andrew McCallum’s<\/a> libbow<\/a> and rainbow<\/a> packages on my Mac. Of course, I had a little bit of trouble, and thought it would be a good idea to document how I went about installing since a quick google search didn’t turn much up. (Not quite true: I turned up one or two references to the packages being available via fink<\/a>, but I couldn’t find them in my setup.) <\/p>\n

Apple Technote on porting command line tools<\/h3>\n

This Apple Technote on porting command line tools<\/a> has some interesting information on header files and other gotchas when working on OSX. <\/p>\n

<\/p>\n

The first problem was <\/p>\n

\r\nmake\r\ngcc -c   -Ibow -I. -I.\/argp -DHAVE_STRERROR=1 -DHAVE_GETTIMEOFDAY=1 -DHAVE_RANDOM=1 -DHAVE_SRANDOM=1 -DHAVE_SETENV=1 -DHAVE_STRCHR=1 -DHAVE_STRRCHR=1 -DHAVE_LOG2F=1 -DHAVE_SQRTF=1 -DHAVE_ALLOCA_H=1  -g -O -Wall -Wimplicit -o array.o array.c\r\nIn file included from array.c:22:\r\n.\/bow\/libbow.h:40:53: error: malloc.h: No such file or directory\r\n<\/pre>\n
This isn’t really a big shock, since Apple has their malloc.h header off in \/usr\/include\/sys\/<\/code>, where GCC wouldn’t be able to find it.  Since in OSX and other POSIX implementations the malloc functions are included in stdlib.h<\/a> I just removed all references to mallo.h from the code.  <\/p>\n
<\/p>\n
That went well, and got me up to <\/p>\n
\r\ngcc -c   -Ibow -I. -I.\/argp -DHAVE_STRERROR=1 -DHAVE_GETTIMEOFDAY=1 -DHAVE_RANDOM=1 -DHAVE_SRANDOM=1 -DHAVE_SETENV=1 -DHAVE_STRCHR=1 -DHAVE_STRRCHR=1 -DHAVE_LOG2F=1 -DHAVE_SQRTF=1 -DHAVE_ALLOCA_H=1  -g -O -Wall -Wimplicit -o array.o array.c\r\nIn file included from array.c:22:\r\n.\/bow\/libbow.h:1631: warning: type qualifiers ignored on function return type\r\n.\/bow\/libbow.h:2128: error: array type has incomplete element type\r\n<\/pre>\n
The warning isn’t a big deal, but the error is a bit more troubling.  This pops up because GCC has become more strict about following the C++ spec on incomplete types (a question on a similar problem<\/a>, see the two follow-ups as well.)  I could try to track things down and make sure that
\nthe extern struct argp_child bow_argp_children[];<\/code> line has the argp_child struct defined before that line, but I thought it was easier to change the version of gcc to 3.3.  Apple ships with a few gcc compilers installed, you can use gcc_select<\/code> to list (-l) and change the default system compiler.  I changed to 3.3.  That got me up to:<\/p>\n
\r\nbarrel.c:22:20: values.h: No such file or directory\r\nbarrel.c: In function `barrel_iterator_count_for_doc':\r\nbarrel.c:1182: warning: division by zero\r\n<\/pre>\n
A quick search of the web turned up the nugget that values.h has been replaced by float.h, so over in the barrel.c file and bow\/svm.h I replaced #include <values.h><\/code> with #include <float.h><\/code> and things went fine, until I ran across a new error:<\/p>\n
\r\nsvm_smo.c:194: error: `MAXDOUBLE' undeclared (first use in this function)\r\nsvm_smo.c:194: error: (Each undeclared identifier is reported only once\r\nsvm_smo.c:194: error: for each function it appears in.)\r\n<\/pre>\n
This was an artifact of swapping in limits.h for values.h, MAXDOUBLE is now called DBL_MAX, so making that change in the broken file fixed that problem.  That actually compiled all of the object files, so now we just have to deal with linking.  Here’s a new error:<\/p>\n
\r\nld: can't locate file for: -lcrypt\r\n<\/pre>\n
It looks like the problem here is that libcrypt does not exist for OSX.  Instead, you can try using libcrypto.  What are the differences?  I have no idea.  So in Makefile.in, I added an “o” to the ALL_LIBS line that specified libcrypt, re-configured, re-made, and then a make install and things are installed wonderfully.  Time to do some model building.<\/p>\n","protected":false},"excerpt":{"rendered":"
