I emerged dev-java/msv on my stable amd64 machine (Intel Core Duo) but found it would not start. It appears that something went wrong in the build process. The ebuild finished with no errors. There are two issues related to the incomplete build: a jar file that complains of a missing Main-Class manifest attribute and the lack of installation of a file mentioned in the README.txt: commandline.html. I installed the thing for the express purpose of getting a command-line schema checker that is better at error reporting than xmllint. When the ebuild finished, I was expecting to have a new "msv" command. That didn't happen, so I looked at the installed files and found that none were installed to any directories in PATH. Pressing on, I thought to try the jar file. This is what happened: $ java -jar /usr/share/msv/lib/msv.jar Failed to load Main-Class manifest attribute from /usr/share/msv/lib/msv.jar The /usr/share/doc/msv-20050627-r2/README.txt.bz2 directed me to look to the file commandline.html for instructions on how to use it from the command line, but I observed the file did not get installed. (I had the USE flags +doc -source.) I unzipped the source tarball from /usr/portage/distfiles/ and found a nice commandline.html there as well as an msv.jar file that worked. I tried its instructions. The upstream-supplied msv.jar worked: $ java -jar /home/mike/lib/msv-20050627/msv.jar docbook.rng work.xml [lots of useful output] but the installed one failed: $ java -jar /usr/share/msv/lib/msv.jar docbook.rng work.xml Failed to load Main-Class manifest attribute from /usr/share/msv/lib/msv.jar Here's a comparison of the sizes: $ ls -l lib/msv-20050627/msv.jar /usr/share/msv/lib/msv.jar -rw-r--r-- 1 mike mike 667496 2005-06-27 22:11 lib/msv-20050627/msv.jar -rw-r--r-- 1 root root 533422 2010-09-03 21:09 /usr/share/msv/lib/msv.jar I ran the ebuild on a computer with more than 300MB of free memory and 200GB of free disk space. I'm not a big Java person, so I did not go into trying to diagnose the problem. Maybe all you wanted to get out of this package is a library, not a command-line tool (which the product itself advertises it has.) I'd be quite willing to make my own Bash script invoke the thing, but the broken jar from the ebuild won't let me do even that. In the meantime I'm using Sun's jar, but it sure would be great for the ebuild to work right! Reproducible: Always Steps to Reproduce: 1. USE="doc -source" emerge dev-java/msv 2. java -jar /ur/share/msv/lib/msv.jar 3. Actual Results: Failed to load Main-Class manifest attribute from /usr/share/msv/lib/msv.jar Expected Results: usage: java -jar msv.jar <opts> <grammar> <instance1> [<instance2> ...] options: -standalone: do not read external DTD specified in grammar/instances. -strict : perform extra check to schema and report error. -dump : dump grammar rather than perform validation. -debug : generate debug messages. -verbose : be verbose. -maxerror : try to report more errors even if they may be false. -warning : display all warning messages -catalog <catalogfile> : use a catalog file (TR9401) to resolve external entities for detail, see http://www.sun.com/xml/developers/resolver/ -version : display version number. -classpath <jar>/<dir> : use this option to specify additional datatype library jar files for RELAX NG validation. Can be specified multiple times -locale <code> : set the language of messages (i.e., "en","ja") -xerces : use Xerces-J parser for parsing grammar and instances. -crimson : use Crimson parser for parsing grammar and instances. -oraclev2 : use OracleV2 parser for parsing grammar and instances. I tried emerging the same package on a different computer, a Lenovo Thinkpad T400 also running amd64 stable. I got the same results there. This is the emerge --info output from that first computer: Portage 2.1.8.3 (default/linux/amd64/10.0/desktop, gcc-4.3.2, glibc-2.10.1-r1, 2.6.29-gentoo-r5 x86_64)

launcher added in msv-20050627-r3. with this version, you can simply run 'msv' from command line.
