undefined symbol: png_create_write_struct
node: 0.8.14 libpng: 1.4.12
Package installed successfully, but if I try one of examples, I got:
node: symbol lookup error: /vagrant/app/node_modules/png/build/Release/png.node: undefined symbol: png_create_write_struct
try ldd on the png.node and kindly send the reply here , if its still relevant :-)
I get this issue too on Ubuntu 12.10 x86_64:
node 0.8.4 libpng: 1.2.49-1ubuntu1
ldd ~/node_modules/png/build/Release/png.node

@victor73 its not linking libpng "clearly"
Make sure your libpng is in your link paths , defined in the .gyp or re-configure it and build it as per your computer's filesystem statistics
