Supported Environment Variables

You can customize your system environment by specifying paths where the compiler searches for certain files such as libraries, include files, configuration files, and certain settings.

Compiler Compile-Time Environment Variables

The following table shows the compile-time environment variables that affect the compiler:
Compile-Time Environment Variable
Description
CL
(Windows)
_CL_
(Windows)
Define the files and options you use most often with the CL variable. Note: You cannot set the CL environment variable to a string that contains an equal sign. You can use the pound sign instead. In the following example, the pound sign (#) is used as a substitute for an equal sign in the assigned string:
SET CL=/Dtest#100
COV_DIR
(Windows)
Same as
PROF_DIR
.
COV_DPI
(Windows)
Same as
PROF_DPI
.
IA32ROOT
(IA-32 architecture and Intel® 64 architecture)
Points to the directories containing the include and library files for a non-standard installation structure.
IA-32 architecture is no longer supported on macOS*.
ICCCFG
Specifies the configuration file for customizing compilations when invoking the compiler using
icc
.
ICPCCFG
Specifies the configuration file for customizing compilations when invoking the compiler using
