Vivado HLS 2017.1 : cc1plus.exe: out of memory allocating 65536 bytes


The hls_math.h library can cause the following error during C-simulation when used in Windows with the GCC compiler:

cc1plus.exe: out of memory allocating 65536 bytes
make: *** [obj/tb.o] Error 1
ERROR: [SIM 211-100] 'csim_design' failed: compilation error(s).
INFO: [SIM 211-3] *************** CSIM finish ***************


This issue is specific to Windows and the GCC compiler and will be fixed in Vivado HLS 2017.3.

Prior to this you will need to use one of the following work-arounds:

  • Use Vivado HLS 2016.4 if you are using Windows.
  • Use Vivado HLS 2017.x on a Linux OS.
