[gem5-users] Error while compiling gem5 in opt mode

[Preet Derasari]

Hi all!

I am trying to compile gem5 in opt mode and it keeps giving me this error:

build/X86/sim/init_signals.cc:65:32: error: size of array 'fatalSigStack'
is not an integral constant-expression
   65 | static uint8_t fatalSigStack[2 * SIGSTKSZ];
      |                                ^
scons: *** [build/X86/sim/init_signals.o] Error 1

  947 |     explicit module_(const char *name, const char *doc = nullptr) {
      |              ^~~~~~~

Can someone help me understand this? I feel like I need to install python
libraries that can fix this maybe?

Thank you.
