Hello, At the end is my output in Terminal while running ./build. The patch I applied is : Perl Extension for SHA-1/224/256/384/512 perl-Digest-SHA-5.71.1.el6.rfx (x86_64) I imagine for those running 32-bit kernels the patch would be: perl-Digest-SHA-PurePerl-5.48.1.el6.rf (noarch) Here is the actual output before patch: ./build Checking if the needed tools for CentOS release 6.5 (Final) are available ERROR: please install "Digest::SHA", otherwise, build won't work. I don't know distro CentOS release 6.5 (Final). So, I can't provide you a hint with the package names. Be welcome to contribute with a patch for media-build, by submitting a distro-specific hint to linux-media@xxxxxxxxxxxxxxx Build can't procceed as 1 dependency is missing at ./build line 266. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
