I downloaded the required files from GNUWin32 LibTiff page. I didn't install it but used the lib and include to run my code. I want to make my code portable.

Here is my basic C++ program taken from LibTiff documentation.

File: abcd.cpp

#include <tiffio.h>

int main()
{
    TIFF* tif = TIFFOpen("foo.tif","r");
    TIFFClose(tif);
    return 0;
}

I want to create an executable abcd.exe.

My folder structure:

MyProject
|
|tifflib
    |
    |include
    |bin
    |lib
    |manifest
|abcd.cpp

These are the commands I ran:

g++ -c -Itifflib\include -o abcd.o abcd.cpp

g++ -Ltifflib\lib -o abcd.exe abcd.o -ltiff

I get the following error:

skipping incompatible tifflib\lib\libtiff.a when searching for -ltiff
skipping incompatible tifflib\lib\libtiff.dll.a when searching for -ltiff
cannot find -ltiff

The error says the files you downloaded are incompatible. You might have mixed up 32 / 64 bit? – nada Jul 19 '19 at 08:46
How do you mean, I mixed up? That my library is 32 bit and OS is 64 bit? – Tarun Maganti Jul 19 '19 at 08:47
But, doesn't windows support both 32 and 64 bit? – Tarun Maganti Jul 19 '19 at 08:47
I recommend a package manager like [conan](https://conan.io/) with a build tool like [cmake](https://cmake.org/). It will handle the dependencies. – Thomas Sablik Jul 19 '19 at 08:48
I'm using 64bit Windows 8 – Tarun Maganti Jul 19 '19 at 08:48
I'll try out conan but my workstation doesn't have access to internet – Tarun Maganti Jul 19 '19 at 08:49
You have to match the .a files with your compiler's version + bits. – nada Jul 19 '19 at 08:49

@TarunMaganti There's an option in g++ to compile for 32 bit `-m32` add it to both your commands and see what happens. – john Jul 19 '19 at 08:50
@nada I don't know what that means.. – Tarun Maganti Jul 19 '19 at 08:50
@TarunMaganti glad to help – john Jul 19 '19 at 08:53

@TarunMaganti If you want 64 bit I'd try and find libtiff somewhere more modern than gnuwin32, that stuff is really ancient – john Jul 19 '19 at 08:53
@john That would mean, I'd have to recompile it for myself right? – Tarun Maganti Jul 19 '19 at 08:55
