Alarm Server start problem and how to compile JCA on Fedora20 64 bit system ?

[lzfneu <lzfneu@live.com>]

hi,

I have two questions to consult you:

1)  I enconter the following error messages (the details are shown below) when I start the Alarm Server by using the following command line on fedora20-64bit system and It seems that I miss JCA package , therefore I want to compile the JCA zip file that support for 64bit system on website: https://sourceforge.net/p/epics-jca/jca/ci/default/tree/
Is my reasoning right ?

Here are the command line and error messages in details for question 1):

2)  I also encounter errors when I compile unzaipped JCA package with ant command and the error message is:  fatal error: epicsVersion.h: No such file or directory
It seems some configuration should be made with config.linux-x86_64.properties file in config folder.
But i don't know how to do.

Could you please help me and thanks in advance !
