ORACLE 10.2 Pro*C precompiler not reading header file

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 ?

PCC-S-02201, Encountered the symbol "size_t" when expecting one of the following : ... auto, char, const, double, enum, float, int, long, ulong_varchar, OCIBFileLocator OCIBlobLocator, OCIClobLocator, OCIDateTime, OCIExtProcContext, OCIInterval, OCIRowid, OCIDate, OCINumber, OCIRaw, OCIString, register, short, signed, sql_context, sql_cursor, static, struct, union, unsigned, utext, uvarchar, varchar, void, volatile, a typedef name, exec oracle, exec oracle begin, exec, exec sql, exec sql begin, exec sql type, exec sql var, The symbol "enum," was substituted for "size_t" to continue. Syntax error at line 88, column 7, file /usr/include/gconv.h: Error at line 88, column 7 in file /usr/include/gconv.h size_t *);

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.

Thank you "EvilTeach"

that was of much help esp "gcc -v" to get include path
