CIL Generation problems

Lately i had some trouble generating CIL. I got some Errors in standard Classes like Retail and SysQuery.

CIL-Generierung: Error 1. Class: SysQuery, Method: queryAddStaticCursorAsRangeAndValue, Exception: System.ArgumentException: Type QueryBuildStaticlink was not found in the CIL that was generated from X++.
\Classes\SysQuery\queryAddStaticCursorAsRangeAndValue
\Classes\RetailStatementPostSalesOrders\createAggregatedSaleLines Err: 351 \Classes\RetailStatementPostSalesOrders\createSalesOrders Err: 351

These errors are logged in the CIL generation log file which is stored in the folder:
C:\Program Files\Microsoft Dynamics AX\60\Server\MicrosoftDynamicsAX\bin\XppIL with the name Dynamics.Ax.Application.dll.log

To get rid of the sysQuery error the following steps did the trick:

1. Compile SysQuery Class 
2. Start Full CIL Generation 

When these steps doesn't solve the problem another option is to deleter CIL Files and restart Full CiL:

1. Stop the AOS
2. Delete files in this folder C:\Program Files\Microsoft Dynamics AX\60\Server\MicrosoftDynamicsAX\bin\XppIL\source
3. Start the AOS again
4. Start full CIL generation
