[FLASH-USERS] Errors occur during 'make' in Mac OS Big Sur.

[RIGON Gabriel]

Hi,

Both errors seems linked to your compilation options - options with 
gfortran (gcc).
This might be due the newer version of gcc, you use.

Try adding -fallow-argument-mismatch and -Wuninitialized to your 
compilation flags.
More information concerning the compilation flags, you use in 
Makefile.h, might be needed if you this doesn't work.

Best,
G. Rigon
