I found how to build CRC32 table for Ogg in JS, if anyone interested: function _makeCRC32Table() { // From https://stackoverflow.com/questions/53438815/hot-to-build-crc32-table-for-ogg const polynomial = 79764919; const mask = 2147483648; const CRCTable = new Uint32Array(256); for (let i = 256; i--;) { let char = i << 24; for (let j = 8; j--;) { char = char & mask ? polynomial ^ char << 1 : char << 1; } CRCTable[i] = char; } return CRCTable; } 22.11.2018, 17:43, &quot...

Please see the documentation: https://xiph.org/ogg/doc/framing.html I would encourage you to use random serial numbers, as intended, also, as any downstream consumers of your files will face limitations similar to the ones you are facing if they want to do anything more with them. But before you go too far down the route of changing the serial numbers, can you tell us what software is

...lding the table produces the same result. I think that generating the table is better than having hardcoded one - for security against the case when somebody accidentally change one character and this table will continue to work in 99% of cases.

Are you saying this is this the first time you've tried to compile it on the cluster? It's easy to determine if g++ is installed and in the PATH - just get a console on the cluster and type "g++". However, AFAIK cluster nodes are not usually configured for software development, are they? Typically you build your code locally and then job it out to the cluster? Greg

I've compiled llvm several times, but this is the first time I saw this error when I was trying to compile it in a cluster. checking tool compatibility... configure: error: g++|clang++|icc required but not found I am pretty sure g++ is installed and in the path. I then downloaded clang++ binary and set path. The error was still there. OS: opensuse 10.1 gcc, g++ version: 4.2.3 Any idea? Bo

Hi, It was suggested that I post my question regarding a LLVM 3.4 performance regression to this mailing list, rather than stackoverflow. So here is the link: https://stackoverflow.com/questions/22902034/llvm-3-4-performance-regressed Thanks :) Jens -- Jens Tröger http://savage.light-speed.de/
