Syntax

Linux:
None
Windows:
/debug
[
:
keyword
]
Arguments
keyword
Is the type of debugging information to be generated. Possible values are:
none
Disables generation of debugging information.
full
or
all
Generates complete debugging information.
minimal
Generates line number information for debugging.
partial
Deprecated. Generates global symbol table information needed for linking.
[no]expr-source-pos
Determines whether the compiler generates source position information at the expression level of granularity.
[no]inline-debug-info
Determines whether the compiler generates enhanced debug information for inlined code.
For information on the non-default settings for these keywords, see the Description section.
Default
/debug:none
This is the default on the command line and for a release configuration in the IDE.
/debug:all
This is the default for a debug configuration in the IDE.
Description
This option enables or disables generation of debugging information. It is passed to the linker.
By default, enabling debugging, will disable optimization. To enable both debugging and optimization use the
/debug
option together with one of the optimization level options (
/O3
,
/O2
or
/O3
).
If conflicting keywords are used in combination, the last one specified on the command line has precedence.
Option
Description
/debug:none
Disables generation of debugging information.
/debug:full
or
/debug:all
Generates complete debugging information. It produces symbol table information needed for full symbolic debugging of unoptimized code and global symbol information needed for linking. It is the same as specifying
/debug
with no keyword.
/debug:minimal
Generates line number information for debugging.
/debug:partial
Generates global symbol table information needed for linking, but not local symbol table information needed for debugging. This option is deprecated and is not available in the IDE.
/debug:expr-source-pos
Generates source position information at the statement level of granularity.
/debug:inline-debug-info
Generates enhanced debug information for inlined code.
On inlined functions, symbols are (by default) associated with the caller. This option causes symbols for inlined functions to be associated with the source of the called function.
IDE Equivalent
Visual Studio:
Debugging > Enable Expanded Line Number Information
(
/debug:expr-source-pos
)
Eclipse:
None
Alternate Options
For
/debug:all
or
/debug
Linux: None
Windows:
/Zi
