The menu ”Options—Compiler” allow the settting of options that affect the compilers
behaviour. When this menu item is chosen, a dialog pops up that displays several tabs.
There are six tabs:
-
Syntax
- Here options can be set that affect the various syntax aspects of the code. They
correspond mostly to the -S option on the command line (section 5.1.5, page 107).
-
Code generation
- These options control the generated code; they are mostly concerned
with the -C and -X command line options.
-
Verbose
- These set the verbosity of the compiler when compiling. The messages of the
compiler are shown in the compiler messages window (can be called with F12).
-
Browser
- Options concerning the generated browser information. Browser information needs
to be generated for the symbol browser to work.
-
Assembler
- Options concerning the reading of assembler blocks (-R on the command line)
and the generated assembler (-A on the command line)
-
Processor
- Here the target processor can be selected.
On each tab page, there are two entry boxes: the first for Conditional defines and the second for
additional compiler arguments. The symbols, and arguments, should be separated with
semi-colons.
The syntax tab of the compiler options dialog is shown in figure (6.23).

Figure 6.23: |
The syntax options tab |

In the syntax options dialog, the following options can be set:
-
Stop after first error
- when checked, the compiler stops after the first error. Normally the
compiler continues compiling till a fatal error is reached. (-Se (see page 109) on the
command line)
-
Allow label and goto
- Allow the use of label declarations and goto statements (-Sg (see
page 109) on the command line).
-
Enable macros
- Allow the use of macros (-Sm (see page 109)).
-
Allow inline
- Allow the use of inlined functions (-Sc (see page 109) on the command line).
-
Include assertion code
- Include Assert statements in the code.
-
Load kylix compat. unit
- Load the Kylix compatibility unit.
-
Allow STATIC in objects
- Allow the Static modifier for object methods (-St (see page
109) on the command line)
-
C-like operators
- Allows the use of some extended operators such as +=, -= etc. (-Sc (see
page 109) on the command line).
-
Compiler mode
- select the appropriate compiler mode:
-
Free Pascal Dialect
- The default Free Pascal compiler mode (FPC).
-
Object pascal extensions on
- Enables the use of classes and exceptions (-Sd (see
page 109) on the command line).
-
Turbo pascal compatible
- Try to be more Turbo Pascal compatible (-So (see page
109) on the command line).
-
Delphi compatible
- Try to be more Delphi compatible (-Sd (see page 109) on the
command line).
-
Macintosh Pascal dialect
- Try to be Macintosh pascal compatible.
The code generation tab of the compiler options dialog is shown in figure (6.24).

The code generation options tab |

In the code generation dialog, the following options can be set:
-
Run-time checks
- Controls what run-time checking code is generated. If such a check fails, a
run-time error is generated. The following checking code can be generated:
-
Range checking
- Checks the results of enumeration and subset type operations (-Cr
(see page 101) command line option).
-
Stack checking
- Checks whether the stack limit is not reached (-Cs (see page 101)
command line option).
-
I/O checking
- Checks the result of IO operations (-Ci (see page 100) command line
option).
-
Integer overflow checking
- Checks the result of integer operations (-Co (see page
101) command line option).
-
Object method call checking
- Check the validity of the method pointer prior to
calling it.
-
Position independent code
- Generate PIC code.
-
Create smartlinkable units
- Create smartlinkable units.
-
Optimizations
- What optimizations should be used when compiling:
-
Generate faster code
- Corresponds to the -OG command line option.
-
Generate smaller code
- Corresponds to the -Og command line option.
More information on these switches can be found in section 5.1.4, page 99.
The processor tab of the compiler options dialog is shown in figure (6.25).
In the processor dialog, the target processor can be set. The compiler can use different
optimizations for different processors.

The verbose tab of the compiler options dialog is shown in figure (6.26).
|
|
Figure 6.26: |
The verbosity options tab |

In this dialog, the following verbosity options can be set (on the command line: -v (see page
95)):
-
Warnings
- Generate warnings. Corresponds to -vw on the command line.
-
Notes
- Generate notes. Corresponds to -vn on the command line.
-
Hints
- Generate hints. Corresponds to -vh on the command line.
-
General info
- Generate general information. Corresponds to -vi on the command line.
-
User,tried info
- Generate information on used and tried files. Corresponds to -vut on the
command line.
-
All
- Switch on full verbosity. Corresponds to -va on the command line.
-
Show all procedures if error
- If an error using overloaded procedure occurs, show all
procedures. Corresponds to -vb on the command line.
The browser tab of the compiler options dialog is shown in figure (6.27).

Figure 6.27: |
The browser options tab |

In this dialog, the browser options can be set:
-
No browser
- (default) No browser information is generated by the compiler.
-
Only global browser
- Browser information is generated for global symbols only, i.e.
symbols defined not in a procedure or function (-b on the command line)
-
Local and global browser
- Browser information is generated for all symbols, i.e. also for
symbols that are defined in procedures or functions (-bl on the command line)
Remark: If no browser information is generated, the symbol browser of the IDE will not work.
The assembler tab of the compiler options dialog is shown in figure (6.28). The actual dialog may
vary, as it depends on the target CPU the IDE was compiled for.
