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