[Thomas Frisch]

Dear All, 

Did anyone installed basilisk on a mac book pro M4. I have  problems when I  do the make

curl https://basilisk.fr/basilisk/basilisk.tar.gz >> basilisk.tar.gz

tar xzf basilisk.tar.gz

cd  basilisk/src 

ln -s config.osx config

make

sk/src/grid/memindex/virtual.h: In function 'mem_assign':

Hi Thomas,

You should be able to overcome that problem adding -D_DARWIN_C_SOURCE in the config file, see:

https://groups.google.com/g/basilisk-fr/c/7b3VHr0rsdg

However, I am still investigating if that is the correct way to resolve the problem.

In the file:

/Library/Developer/CommandLineTools/SDKs/MacOSX15.5.sdk/usr/include/sys/mman.h

those functions/macros are clearly defined only if _POSIX_C_SOURCE is NOT defined and if _DARWIN_C_SOURCE is defined:

265 #if !defined(_POSIX_C_SOURCE) || defined(_DARWIN_C_SOURCE)

266 int     madvise(void *, size_t, int);

267 int     mincore(const void *, size_t, char *);

268 int     minherit(void *, size_t, int);

269 #endif

Best,

Edoardo

Correction: those functions are defined if _POSIX_C_SOURCE is NOT defined OR if _DARWIN_C_SOURCE is defined.

So defining _DARWIN_C_SOURCE is a workaround but I'm not sure why it is necessary.
