Hi All,
after I precompile my program with gpre -cxx -e ivdconf.exx

int main(int argc, char *argv[])
{
 EXEC SQL DATABASE DB = 'ibtest.gdb';
 EXEC SQL CONNECT DB;
}

and the compile it with gcc -o ivdconf -I/usr/include ivdconf.cxx -lgds -ldl

I recevie following errors:

/usr/include/ibase.h: In function `int main(int, char **)':
In file included from ivdconf.exx:8:
/usr/include/ibase.h:275: parse error before string constant
ivdconf.exx: At top level:
ivdconf.exx:12: syntax error before `='
ivdconf.exx:14: syntax error before `='
ivdconf.exx:17: syntax error before `='
ivdconf.exx:7: parse error before `{'
ivdconf.exx:9: warning: ANSI C++ forbids declaration `SQLCODE' with no type

ivdconf.exx:9: warning: implicit declaration of function `int
isc_sqlcode(...)'
ivdconf.exx:10: parse error before `}'

Could somebody please help me solving this problem.
