ISE Simulator (ISim) - "WARNING:Simulator:1010 - One or more environment variables have been detected which affect the operation of the C compiler."

Description

I am running a simulation using ISE Simulator, but the simulation fails due to the following messages:

"WARNING:Simulator:1010 - One or more environment variables have been detected which affect the operation of the C compiler..."

"FATAL_ERROR:Simulator:Fuse.cpp:508:1.95.2.22 - Failed to compile generated C file isim/test_mux_isim_beh.exe.sim/work/a_3764543196_3212880686.c Process will terminate. For technical support on this issue, please open a WebCase with this project attached at http://www.xilinx.com/support."

How can I resolve this problem?

Solution

This fatal error can occur if certain GCC-specific system environment variables are set. Setting these environment variables might cause the ISim compiler to fail. These include (but might not be limited to):

GCC_EXEC_PREFIX

CPATH

C_INCLUDE_PATH

CPLUS_INCLUDE_PATH

OBJC_INCLUDE_PATH

COMPILER_PATH

LIBRARY_PATH

To resolve the fatal error, disable the environment variables above.
