Basic festival program has undefined reference errors

Question

I am currently trying to compile this basic festival program

#include <iostream>
#include <festival/festival.h>

#define HEAP_SIZE 210000
#define LOAD_INIT_FILES 1

using namespace std;


int main()
{
    festival_initialize(LOAD_INIT_FILES, HEAP_SIZE);

    festival_say_text("Hello World");

    festival_wait_for_spooler();

    return 0;
}

When I try to build the program with g++, I get these errors:

speech_tools/lib/libestools.a $USER/Downloads/festival/speech_tools/lib/libeststring.a

As per http://festvox.org/docs/manual-2.4.0/festival_28.html#C_002fC_002b_002b-API, I added festival/src/include and speech_tools/include to the search path, in addition to linking with festival/src/lib/libFestival.a, speech_tools/lib/libestools.a, speech_tools/lib/libestbase.a, and speech_tools/lib/libeststring.a.

I am trying to build this on Arch Linux with g++ and festival 2.4.0.

EDIT: Build command I'm using is

g++ -o bin/Debug/festival_test obj/Debug/main.o /usr/lib/libcurl.so /home/joshua/Downloads/festival/festival/src/lib/libFestival.a /home/joshua/Downloads/festival/speech_tools/lib/libestbase.a /home/joshua/Downloads/festival/speech_tools/lib/libestools.a /home/joshua/Downloads/festival/speech_tools/lib/libeststring.a

I am using CodeBlocks so this is the default build command

EDIT 2: Adding -lncurses to the build command eliminated the undefined reference errors relating to readline, but the other errors still persist

/home/joshua/Downloads/festival/speech_tools/lib/libestools.a(EST_PST.o): In function `EST_PredictionSuffixTree::test(EST_String)':

wfst_ops.cc:(.text+0x17d8): undefined reference to `EST_THash<int, int>::~EST_THash()'

EDIT 3: Setting libestbase to link last fixed the error.

The order of libraries is also important, estbase must be the last one. — Nikolay Shmyrev, Nov 14 '17 at 09:55

It may be related to this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=499837

It suggests that you explicitly link in the ncurses library for the readline library that seems to be included by another of your libraries. So you would add:

-lncurses

to your command.

Added -lncurses to the build, eliminated all readline errors but I still get the other undefined reference errors – Mike Stache Nov 13 '17 at 22:12
