Question

I’m pre-compiling a C program containing Pro*C code with Oracle 10.2 and AIX 5.2

The Oracle precompiler reads the $ORACLE_HOME/precomp/admin/pcscfg.cfg file which contains the definition of the sys_include variable (set to /usr/include).

The Pro*C compiler complains that it doesn’t know what the size_t type is and the Oracle header files that use the size_t type are reporting errors.

Here’s an example error being reported on the sqlcpr.h file:

extern void sqlglm( char*, size_t*, size_t* ); ...........................1 PCC-S-02201, Encountered the symbol 'size_t' when expecting one of the following 

size_t is defined in the stdio.h header file in the /usr/include directory. I’m including the stdio.h header in my example.pc file before I include the sqlcpr.h header.

I’m issuing the proc command as follows:

proc iname=example parse=full 

Any ideas what I’m doing wrong?

Solution Description

The ‘sys_include’ and ‘include’ precompiler options are not set correctly. Set ‘sys_include’ and ‘include’ precompiler options in the pcscfg.cfg file located at $ORACLE_HOME/precomp/admin or include on the command line when invoking ‘proc’.

For example, here is a recommended way to set the variable properly:

Run the following command to obtain the compiler location:

gcc -v

Reading specs from /usr/lib/gcc-lib/i386-redhat-linux7/2.96/specs gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-128)

Use the path returned above (remove specs and replace with include)

sys_include=($ORACLE_HOME/precomp/public,              /usr/lib/gcc-lib/i386-redhat-linux7/2.96/include,               /usr/include)  include=(/u02/app/oracle/product/8.1.5/precomp/public) include=(/u02/app/oracle/product/8.1.5/rdbms/demo) include=(/u02/app/oracle/product/8.1.5/network/public) include=(/u02/app/oracle/product/8.1.5/plsql/public) 

I am guessing that the part of having both sysinclude and include is your issue.
