    Errors in Hell World Program

    HI All,

    I very new to 3D programming and to Collada..

    I compiled collada Dom and its third party libraries using Mingw..
    I am compiling the below example program using DEV-C++.

    i am using pcre 7.7, zlib123 and GNU Make 3.81.. while compiling the below program i am recieving errors ..
    [Linker error] undefined reference to `inflateInit2_'
    [Linker error] undefined reference to `get_crc_table'
    [Linker error] undefined reference to `crc32'
    [Linker error] undefined reference to `inflate'

    and many more.. i downloaded latest external libs specified in the page Building_third_party_libraries_for_the_COLLADA_DOM and compiled it...

    i am able to solve some linker problems.. but still it is giving errors...

    #include <iostream>
    #include <dae.h>
    #include <dom/domCOLLADA.h>
    using namespace std;

    int main() {
    DAE dae;
    printf("heloo World");

    return 0;
    }

    Re: Errors in Hell World Program

    Those are linker errors. Since you are statically linking, I think you need to order your library dependencies so that references are resolved correctly.

    For example libpcrecpp.a needs to come before libpcre.a.

    Re: Errors in Hell World Program

    Thanks Marcus...

    I am able to solve linker errors by reordering the library dependencies..

    but find an error, again saying zlib1.dll missing.. i downloaded zlib123.dll's and now its working fine...


    Thanks for your reply

    This is the order of the library dependencies i am using.. may be usefull if someone is looking for..
