Undefined references when using manually downloaded SFML version

[codecodecode]

When I install sfml 2.1 from the repo (on ubuntu), it works just fine. But when I download the same version from the download page, it throws out these errors:

I copied all the glew files into the lib folder, but the problem persists (I found out I don't have libGLEW.so.1.7 on my system btw). How to fix this problem?

Install the latest version of SFML. 2.1 is really old.

I tried to, but hit a brickwall. I'm trying to install 2.1 from another location with the idea that it'll help me infer why 2.4.2 doesn't work for me.

Before 2.1 I tried installing 2.3.2, but it behaves the same way as 2.4.2.

You're using Linux, why won't you simply recompile SFML and install it (or pack into .deb package)? Btw if you're using Ubuntu 16.04 or newer you can install SFML 2.4.1 from .deb prepared by me, it's packaged with QSFML releases.

[Laurent]

Ok so stop messing with multiple versions, and let's first solve your problem with 2.4.2 in that other thread. Then this problem should be solved too (SFML > 2.2 no longer depends on GLEW).

That's what I was doing before that, with no success.

Btw if you're using Ubuntu 16.04 or newer you can install SFML 2.4.1 from .deb prepared by me, it's packaged with QSFML releases.

On 14.04.
