Assertion failure with DBTools.h++ examples

Problem

---

I am running into a problem when I run the tutsetup.exe.

 

Assertion failed: ((!needAll || maxdigits == 0)) != 0,
file D:/spm/parts/tls0710wsourcesrclocale.cpp, line 1068

---

Cause

---

When Tools.h++ libraries are built with the RW_CENTURY_REQD flag, the use of four-digit years is enforced. The normal behavior when a 2-digit year is encountered in debug mode is an assertion failure such as this:

Assertion failed: ((!needAll || maxdigits == 0)) != 0,
file D:/spm/parts/tls0710wsourcesrclocale.cpp, line xyz

 

The problem when running the DBTools examples is that the data files contain 2-digit years.

Action

---

The solution is to modify the data files to use 4-digit years exclusively. The data files you need to change are:

purchase.dat, rental.dat, and t4in.dat

You may change these files once for all builds in the directory:

..spmpartsdbt0320wexamplessrc

Then rebuild the DBTools examples. This will affect all subsequent builds of the examples.

You may also change the data files for the specific build you've done by going to this directory:

..spmworkspaces(OS)(compiler)(buildType)dbt0320wexamples

After the files are modified, run tutsetup again.

(These examples indicate DBTools 3.2.0. Change the version number according to what you are using. On Unix, the w on dbt0320w should be changed to u.)

The data files will be corrected in a future version of DBTools.h++.
