I was trying to compile sphinx server from source but I go the following errors on executing make
undefined reference to `libiconv_open’
undefined reference to `libiconv’
undefined reference to `libiconv_close’
To fix the error, you can compile without iconv (multiple encoding support) support. Use the following commands to compile. You can add more parameters as per your requirements.
./configure --without-iconv make CFLAGS=-liconv make install
I hope that helps
