Trouble building srilm project (macosx)

[Foster, George]

Peter,

I'm running a version of OSX 10.3.9 and gcc that's almost identical to yours:

% uname -a
Darwin 0547-CRTL.local 7.9.0 Darwin Kernel Version 7.9.0: Wed Mar 30 20:11:17 PST 2005; root:xnu/xnu-517.12.7.obj~1/RELEASE_PPC  Power Macintosh powerpc

% gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.3/specs
Thread model: posix
gcc version 3.3 20030304 (Apple Computer, Inc. build 1495)

I had no problems building srilm 1.4.5 using the INSTALL instructions
(no code changes necessary).

George

I joined this group in hopes of finding some help on the MacOS compile.

I'm getting a handful of uninstantiated templates in the out-of-the-box 
compile on OS X 10.3.9, with compiler version:

gcc version 3.3 20030304 (Apple Computer, Inc. build 1666)

The undefined functions are, in various executables:

FNgramCounts<unsigned int>::FNgramCounts(FactoredVocab&, 
FNgramSpecs<unsigned int>&)
Map2<unsigned int, unsigned int, double>::clear()
NgramCounts<unsigned int>::NgramCounts(Vocab&, unsigned int)

I was able to 'fix' ngram-counts by adding

#include "NgramStats.cc"

to the main program.

The same fix does not work for ngram.cc.

Additional investigation shows that the instance file

NGramStatsInt.o

does not include an instantiation of the NGramCount constructor.

Other attempts like adding this to the main program:

static template NGramCounts<unsigned>;

lead to multiple definition errors in the linker.

Is there a known configuration or compiler option that works on OS X 
10.3?  Or will upgrading to 10.4 fix the problems?

thanks,

Peter McIlroy
