Manual install of pycelib reports back liberasurecode-1.0.7 install failed. Checked with one of the developers and he indicated liberasurecode failing to install was a bug. Please let me know if you need any further information.

@tsg- I am a little confused by the warning from GCC... pos is a signed long, so this should not be complaining. Any ideas?

@aplimpton - Can you please send us the version of clang or gcc you are using?

[A Plimpton]

Sure thing! Survey says: $ gcc --version Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn) Target: x86_64-apple-darwin14.3.0 Thread model: posix

@aplimpton this was fixed in https://bitbucket.org/tsg-/liberasurecode/commits/18276412fd7780623ae4222a7c14ce65f04a7ebf. Should be included in 1.0.8, which is to be out soon.

@aplimpton, would you be able to give the latest "master" a try on your Mac and see if it builds for you so we can tag "1.0.8"? Many thanks!

[A Plimpton]

Gave it a try and build worked!

Thanks so much :)
