Dear all,

I tried to install Cryo_fit on my labtop Macbook pro M1 running OSX 13.0.

The installation of the Cryo_fit itself in Phenix went well.

I then tried to install gromacs (gromacs-4.5.5_cryo_fit) following the instructions found on https://phenix-online.org/documentation/tutorials/cryo_fit_install.html#id1

But during the compilation, I encoutered the following error that stops the process.

cc -DHAVE_CONFIG_H -I. -I../../src -I/usr/include/libxml2 -I../../include -DGMXLIBDIR=\"/Applications/phenix-1.20.1-4487/modules/cryo_fit/cryo_fit/share/top\" -O3 -fomit-frame-pointer -finline-functions -Wall -Wno-unused -msse2 -std=gnu99 -I./include -MT md.o -MD -MP -MF .deps/md.Tpo -c -o md.o md.c

I did it under a bash shell,
