undefined reference to `gdImageSetPixel'

While I can compile on Mac, when I try to compile on the latest Ubuntu, I get:

make: *** [waveformgen] Error 1

I have the package libgd2-xpm-dev 2.0.36rc1dfsg-6.1ubuntu1 installed.

Any ideas?

Mh, this seems odd, as even sort gives an undefined reference error.

Never compiled it on Linux, might try it later in a VM to see if I get the same error.

Hi,

I set up a fresh 13.04 Ubuntu in a VM, installed following:

build-essential cmake git libsndfile-dev libgd2-xpm-dev

cloned repo

cd waveformgen
mkdir build
cd build
cmake ..
make

and initially had a problem not linking to libm, which I fixed the cmake file in the last commit. Now it compiles and installs without problems. I couldn't reproduce your error messages and don't know much about Linux, so can't really help you.

Did you have any luck?

Fantastic, It compiles just fine with the latest master! - thank you :D
