Box2D dependency issue on build #709

Open aborthonormal opened 8 years ago

aborthonormal commented 8 years ago

I am running into an issue when attempting to compile Polycode from source. Specifically, the script for downloading and installing the Box2D dependency seems to use an invalid URL.

Here is a portion of the build output:

Scanning dependencies of target box2d [ 9%] Creating directories for 'box2d' [ 10%] Performing download step (download, verify and extract) for 'box2d' -- downloading... src='http://box2d.googlecode.com/files/Box2D_v2.1.2.zip' dst='/home/andrew/Downloads/Polycode-master/Dependencies/Downloads/Box2D_v2.1.2.zip' timeout='none' CMake Error at box2d-stamp/download-box2d.cmake:9 (file): file DOWNLOAD HASH mismatch

I am running 64-bit Ubuntu: 4.2.0-27-generic #32~14.04.1-Ubuntu SMP Fri Jan 22 15:32:27 UTC 2016 i686 i686 i686 GNU/Linux

I've attached the full output of the build script "BuildLinux.sh" to this post. I also attempted building the dependencies separately using cmake, as described in the README.md file. I ran into the same issue. Perhaps I just need to update the URL and MD5 hash for Box2D 2.1.2 in the build script? I'm also curious to see if anyone else has had this issue recently.

Fixed! (sort of)

I found a valid URL for the 2.1.2 version of Box2D: https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/box2d/Box2D_v2.1.2.zip

Since the BuildLinux.sh script failed at the Box2D download verification, I just had to copy the zip file to the "Dependencies/Downloads" folder. I confirmed the MD5 hash is the same.

A better fix would be for the files in "Dependencies/Build/Debug/box2d/src/box2d-stamp" be updated to use the valid URL. I'm a novice at Git, so I don't want to mess anything up by pushing a change to the Polycode repo. Perhaps someone with more experience could make this update?

You have to open the Dependencies/Build/Debug/src/box2d-stamp/download-box2d.cmake and replace every http://box2d.googlecode.com/files/Box2D_v2.1.2.zip by https://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/box2d/Box2D_v2.1.2.zip
