#89 Failure to Build CDK on Linux (Boca)

[Anonymous]

After trying to build the freac cdk, both from the tarball on the website and from CVS HEAD (the boca module) it failed to build in part due to case sensitivity between directory names on my opensuse box and where gcc was searching. The Other problem A change was made from lower case to upper case in revision 1.7 from 1.6 in two files. A third had the same modification between revisions 1.3 and 1.4.

The other issue was related to search paths for the same header files. On my rig i had to swap the greater than and less than signs for double quotation marks for gcc to find the header files correctly. Finally here's the output from stderr before my patch, the other files have similar errors.

I've included diffs from the boca directory for use with patch. i.e. from cvsroot/bonkenc/boca/ run patch xxxx.diff, sorry if that isn't the standard directory for you.

Thank you for your interest in fre:ac!

The BoCA components are meant to be compiled with FLAC headers available on your system. They are usually located in /usr/include/FLAC (upper case) when the libflac-dev package is installed. That's why I changed the include directives to upper case a few months ago.

The FLAC headers included in the CDK package are provided for convenience when building on Windows systems. Directories are case insensitive there and the Makefiles add the -I. flag to allow finding the headers even with the <> brackets.

You should be able to build the CDK without you patches after installing the libflac-dev package.
