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 build/X86/sim/init.cc: In static member function 'static PyObject* EmbeddedPyBind::initAll()': build/X86/sim/init.cc:201:41: warning: 'pybind11::module_::module_(const char*, const char*)' is deprecated: Use PYBIND11_MODULE or module_::create_extension_module instead [-Wdeprecated-declarations] 201 | py::module_ m_m5 = py::module_("_m5"); | ^ In file included from build/X86/sim/init.hh:44, from build/X86/sim/init.cc:44: ext/pybind11/include/pybind11/pybind11.h:947:14: note: declared here 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.

Hi Preet, I faced this error when I was trying to compile an old version of Gem5 (from 2018) on a relatively recent system with the latest glibc/gcc. SIGSTKSZ used to be a macro in older glibc/gcc. You can simply set the size of fatalSigStack to 8192.
