Subject: problem with the ecpg -D option
Date: Thu, 31 Aug 2000 03:35:30 -0700 (PDT)
Message-ID: <20000831103530.6928.qmail@web2105.mail.yahoo.com> (raw)
Configuration :
system : sun sparc ultra 5
os : solaris 2.7
postgres : 7.0.2
compilator : cc compilator from the workshop.
Problem:
I used the ecpg tool in order to build a c program.
I would like to use a conditional compilation in
order to have the same code to acces different system
database but the ecpg tool just copy the #ifdef
statements to the c program.
Example:
#ifdef ORACLE
exec sql fetch cursor_name into :s_variable /* fetch
instruction for an oracle database */
#endif
The preprocessor just copy those lines to the c
program whereas it should ignore them and as the fetch
statement which was deserved for oracle is
unrecognised by postgres, the preprocessor is unable
to parse the file.
I try with the -D option, thinking it works like the
-D option in C but it doesn't.
Thanks in advance.
