Usually, this happens when the JAVA_HOME environment variable is not properly set. However, I only tested the distribution against full JDKs, but not against mere JREs. Could you check the value of the JAVA_HOME environment variable, and also tell me whether you have a file with the path $JAVA_HOME/lib/ct.sym ? |

You are correct, the compilation proceeds when JDK is used instead of JRE. lib/ct.sym is not present in the JRE. As far as runtime goes, the native executable solves the queens problem for an 8x8 board in 4ms. The java version, who knows - but a very long time. |

I don't know yet if it will be possible to support bare JREs, but will take a look at it. Regarding "queens.ml", the bug in OCaml-Java is indeed in the "read_int" primitive... the computation is never launched. If modified to remove the interactive part, the program exhibit decent performances. |
