Pro*C Program Fails Compilation for SIZE_T in SQLCPR.H with Version 12.1 (Doc ID 2025201.1)

Last updated on MARCH 20, 2017

Applies to:

Precompilers - Version 12.1.0.1 to 12.1.0.2 [Release 12.1]
Information in this document applies to any platform.

Symptoms

1) A Pro*C program fails during the C compilation stage for "size_t" referenced in sqlcpr.h, saying it is undefined. 

2) The program is not directly including sqlcpr.h, but is including sqlda.h.

3) The Oracle client version is 12.1.0.1 or 12.1.0.2.

4) The same code compiles successfully with an 11g installation.

For example, compilation of the above code fails with errors like:

".../precomp/public/sqlcpr.h", line 79: error #2020: identifier "size_t" is undefined 

 or:

.../precomp/public/sqlcpr.h:79: error: expected declaration specifiers or '...' before 'size_t'

 

Changes

The client software was upgraded to version 12.1 or a new Pro*C program is being compiled with 12.1.
