For first-time install copy file "tacppd_start.sh.orig" to "tacppd_start.sh" and edit it for your directory (read comments in file). For first-time install copy file "etc/tacpp.conf.orig" to "etc/tacpp.conf" and review it (and read "etc/README"). Check if you have workable database libraries (database modules require it). For it, check database module which you will use by ldd:
ldd db/postgresql.so
ldd db/mysql.so
if you see library libpq.so/libmysqlclient.so inside - all right in other case, check you /etc/ld.so.conf or LD_LIBRARY_PATH for path to appropriate shared library (and your PostgreSQL/MySQL too)
REMEMBER! you MUST HAVE appropriate PostgreSQL or MySQL libraries (or miniSQL, if you will use this driver), if you plan to use Oracle, than you m ust have Oracle client installed and configured.
