While executing make command, I recieve the following error:

Answer 1

The -liconv appears nowhere in the link command, so that's why you're getting the undefined references. Try putting:

 SYS_LIBRARIES = -L<path-to-libiconv_install> -liconv

For example, if you install srilm on Ubuntu x64, edit this file: common/Makefile.site.i686-m64. Make sure the -L option points to the directory that has the libiconv.so or libiconv.a file.

For me, libiconv install srilm on Ubuntu 18.04 x64 using make are locate on /usr/local/lib. So I add following line to common/Makefile.site.i686-m64:

SYS_LIBRARIES = -L/usr/local/lib -liconv
