The compiler displays status information while compiling if you have checked "Show general messages" on the Compiler page of the Project Options dialog box. Most of the messages are self-explanatory and state information about compiling and linking; for example:

[C++] Compiling: D:\Program Files\Borland\CBuilder\Bin\Unit1.cpp

You may also see a message such as

[C++] Including clx.h instead of clx.h due to -Hr switch

This message indicates that the IDE-managed precompiled header file was replaced due to additional CLX classes being included in the project. It does not indicate a failure condition. Sometimes the header file name being included may be the same if it is being included with a different #define statement.
