Building Krusader under Kubuntu/Ubuntu 18.04 LTS (and some other distributions) shows some minor errors like:
Note: Writing krusader.1 [100%] Built target doc-krusader-1 [100%] Generating index.cache.bz2 introduction.docbook:96: parser error : Entity 'NFS' not defined servers, TAR archives, &NFS; filesystems, SAMBA shares, ISO ^ introduction.docbook:106: parser error : Entity 'NFS' not defined (&FTP;, &NFS;, Samba, FISH, SFTP).</para> ^ introduction.docbook:152: parser error : chunk is not well balanced ^ index.docbook:347: parser error : Failure to process entity introduction &introduction; ^ index.docbook:347: parser error : Entity 'introduction' not defined &introduction; ^ kf5.kdoctools: Error: `xmllint --noout` outputted text doc/CMakeFiles/doc-index-cache-bz2.dir/build.make:95: recipe for target 'doc/index.cache.bz2' failed make[2]: *** [doc/index.cache.bz2] Error 1 CMakeFiles/Makefile2:2263: recipe for target 'doc/CMakeFiles/doc-index-cache-bz2.dir/all' failed make[1]: *** [doc/CMakeFiles/doc-index-cache-bz2.dir/all] Error 2 Makefile:140: recipe for target 'all' failed make: *** [all] Error 2
although that doesn't allow Krusader to be built.
The problem doesn't happen if the proposed patch is applied, although maybe there are better solutions :-?
