/LTCGOUT (Name LTCG incremental object file)

The /LTCGOUT linker option tells the linker where to put the intermediate .iobj object file for incremental link-time code generation (/LTCG:INCREMENTAL).

Syntax

/LTCGOUT:[pathname]

Arguments

pathname
The optional destination directory and filename for the generated .iobj file. If the /LTCGOUT option isn't specified when /LTCG:INCREMENTAL is used, the filename is created by appending .iobj to the target base filename. If the /LTCGOUT option is specified with an empty pathname when /LTCG:INCREMENTAL isn't used, no .iobj file is generated.

Remarks

The /LTCGOUT linker option tells the linker the path and filename to use for the intermediate .iobj object file when you specify /LTCG:INCREMENTAL. If you remove the /LTCG:INCREMENTAL option from your project, you should also remove any /LTCGOUT option.

2. Select the Configuration Properties > Linker > Optimization property page.

3. Modify the Link Time Code Generation Object File property. The option isn't set if this property is empty.
