16 | Purpose: Check the SrcFileTime of the ccdgen generated header files at link time.
17 |
18 | The macros in this file help to detect version mismatch between
19 | header files included for build of different libraries.
20 | Example of a linker error:
21 | xx_tdc_3_constraints.obj : error LNK2001:
22 | unresolved external symbol
23 | "char BadLibVersionCheck____P_XX_TDC_3_VAL_H____Thu_Dec_12_17_49_56_2002"
24 | (?BadLibVersionCheck____P_XX_TDC_3_VAL_H____Thu_Dec_12_17_49_56_2002@@3DA)
25 | \gpf\util\teststack\bin\test_xx_tdc\xx_tdc.dll :
26 | fatal error LNK1120: 1 unresolved externals
27 | Error executing link.exe.
28 |
29 | The first group of macros (protected by PUB_L1_MISC_ENTER) are necessary
30 | to build the strings of type "BadLibVersionCheck__xxx".
31 |
32 | They need in turn other macros which are set in the *.h files of
33 | cdginc, tdcinc or message_san.h directory.
34 | (e.g. PUB_L1_MISC_ENTER__M_XX_VAL_H__FILE_TYPE)
35 |
36 | The check is done only for the header files where
37 | ENABLE__PUB_L1_MISC_ENTER__SANITY_CHECK is switched on.
