Hi,
I have a set of libraries and C/C++ programs with embedded access to
a PG database. I'm using ecpg. I'm working on a Linux RedHat9 platform.
Until now I was in PG 7.4.2 :
[clipg@li SrcLib]$ ecpg --version
ecpg (PostgreSQL 7.4.2) 3.1.1
[clipg@li SrcLib]$ g++ --version
g++ (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
Copyright (C) 2002 Free Software Foundation, Inc.
and without any problem.
I installed PG 8.0.0beta2 :
[clipg@li SrcLib]$ ecpg --version
ecpg (PostgreSQL 8.0.0beta2) 3.2.0
And if I try to recompile I find pre-compiled errors, variables which
are defined in an include file are not "seen".
Is there any known problem or bug about this ?
Detail :
======= Precompiling DbTablesFk.pgc =======
ecpg DbTablesFk.pgc -I/VALE/users/clipg/Server/Include -o DbTablesFk.cc
DbTablesFk.pgc:144: ERROR: trying to access an undeclared cursor MAX_FK
DbTablesFk.pgc:144: ERROR: syntax error at or near "IN"
and in the program :
...
EXEC SQL INCLUDE DbTablesUtilPg.hh;
...
EXEC SQL PREPARE S FROM :sqlstmt;
EXEC SQL DECLARE C_FK_COL CURSOR FOR S;
EXEC SQL OPEN C_FK_COL;
EXEC SQL FETCH MAX_FK IN C_FK_COL INTO :fk_id_L , :valid_L, :target_t_L;
with MAX_FK a variable defined in the file
/VALE/users/clipg/Server/Include/DbTablesUtilPg.hh :
exec sql define MAX_FK 100;
If I replace the MAX_FK variable by its value it's OK.
If I define the MAX_FK variable directly in the program (and not
in an include file) it's OK.
Any idea ? Thanks for all, Valerie.
