libpng15.15.dylib not loaded about wav2png

[beschulz]

I'd suggest to use the XCode project to build ob Mac OS. I must admit, that I am not sure, if clang and libpng-config are installed per default on Mac OS. Do you have installed xcode?

Hope this helps

Starting with Xcode 4.3, Apple does not install command line tools by default anymore, so after Xcode installation, go to Preferences > Downloads > Components > Command Line Tools and click Install. You can also directly download Command Line Tools for Xcode without getting Xcode (https://developer.apple.com/downloads).

I think, that you should be able to compile wav2png via make, after installing the Xcode command line tools.

Hi Benjamin,

Thanks for the replies. I actually only have Xcode 3.2.4, so I think the command line tools area already installed. My problem may be that i don't have libpng-config or clang installed. I found this tutorial on installing libpng http://kenno.wordpress.com/2006/04/20/compiling-libpng-for-mac-os-x/. I installed it, as well as its dependency zlib.

I downloaded the binary of clang++.

This fixed the dependency issues. However, now when I try to compile I get this error:

make
mkdir -p dirname ./bin/Darwin/wav2png
/path/to//lib/clang++/clang+llvm-3.1-x86_64-apple-darwin11/bin/clang++ -O3 -Wall -Werror -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/X11/include/ -I./dependencies/include libpng-config --ldflags -lsndfile -lboost_program_options-mt ./src/*.cpp -o ./bin/Darwin/wav2png
./src/main.cpp:1:10: fatal error: 'sndfile.hh' file not found
#include <sndfile.hh>

Thoughts? Thank you,

Yes, this one is easy. libsndfile is a dependency. The easiest way to install it on Mac OS X is via homebrew:

1.) Install Homebrew (If you havent allready)
https://github.com/mxcl/homebrew/wiki/installation
2.) install libsndfile:
brew install libsndfile

Thanks for pointing out the issues, I'll update the build instructions.

Cheers

I've updated the build instructions for Mac OS X. I know, that it is a little bit more complicated than on linux, because installing the dependencies is a little harder.

I've forgot to mention earlier, that you also have to install png++ and put it into dependencies/include.

Thanks. I also had to install the boost c++ libraries.

And then, I was having issues with the version.hpp file. So i created it manually in a text editor. You may need to review the Makefile, because the creation of the version.hpp file did not work for me (or remove that process altogether). I also had to compile libpng15 on my computer because i had libpng12. I also installed sox with homebrew for mp3 conversion.

Once that was all setup, I finally was able to compile it! It's bloody fast.

Thanks for your help.
