Using the PCBridge Software
Appendix D
D-9
After HELLO is transferred, the PCBridge software looks for the symbol
module created by the cross C compiler. If found, the symbol file
HELLO.STB is transferred and the debugger is invoked. The debug
prompt lets you know that the debugger has been started:
dgb:
For complete information about the debugger, see the OS-9 C Language
User Manual, publication 1771-6.5.104—for example, chapter 6 of this
manual explains how and where to load the online-help file for the source
debugger, SRCDBG.HLP, on the control coprocessor.
The PCBridge menu and communications facilities remain in memory
when you compile and assemble programs, which may result in memory
limitations. To overcome such memory limitations, quit the PCBridge
software and call the compiler or assembler directly from the PCDOS
command line. With the PCBridge software no longer in memory, there
is more memory available for the task. You can call the linker directly
on the command line to link several compiled modules into one OS-9
memory module.
The cross-compiler contains several options that alleviate DOS constraints.
It is linked with the Phar Lap 286-DOS Extender to allow the use of
extended memory.
Information on the C compiler is found in the OS-9 C User Manual,
publication 1771-6.5.104. Information on the assembler and linker
is found in the OS-9 Assembler/Linker User Manual, publication
1771-6.5.106.
