make: ** [srilm.o] Error 1

I guess instead of strdupa strdup should be used for the sake of the compilation of the modules.

Is it possible to get the probability of higher than trigram like 4-gram or 5-gram?

Some information:

• GLIBC version:2.21
• Kernel version: 3.19.0-18-generic
• SRILM version: 1.7.1

I'm trying to make the perl module in the swig-srilm.
I was doing it like it is in the README file. I already followed all the previous steps, changed the paths of the variables in the file Makefile, but when I try to execute the command "make perl" I keep getting this error:

g++ -shared srilm.o srilm_perl_wrap.o -loolm -ldstruct -lmisc -lz -lgomp -L/home/farid/Documents/6to/NLP/SRLIM/lib/i686-m64/ -o srilm.so

I already tried including the -fPIC but the error is still there, I tried deleting the shared field in the command but instead I get another error:

I'm trying to install the wrapper but I keep getting multiple errors.

I've tried with the OS X shipped GCC and GCC installed using home-brew (versions 4.9 and 5).

Any other suggestions?

make: *_* [srilm.o] Error 1

I ran into a problem getting swig-srilm to play nicely with the srilm libraries on my system, with the error:

/usr/bin/ld: /home/jmoore/src/loglanguage/srilm/srilm/lib/i686-m64/liboolm.a(Prob.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/home/jmoore/src/loglanguage/srilm/srilm/lib/i686-m64/liboolm.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
make: *** [_srilm.so] Error 1

As the error states, I needed to recompile Prob.o (and all the other srilm libraries) with the -fPIC flag to G++.

I couldn't find how to do that the "right" way, so I ended up editing the $SRILM/common/Makefile.machine.i686-m64 to add -fPIC to the GCC_FLAGS line.

My suggestion is to mention this in the documentation (readme or somewhere) in case somebody else runs into this same problem.
