Errors in Hell World Program

Other Standards COLLADA
1

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;

}

i am adding compile log…

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.

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… :slight_smile:
