<div class=""><br class="">
</div>
<div class="">Sorry about the delay in getting back. I couldn’t spend much time on this until now.</div>
<div class=""><br class="">
</div>
<div class="">Tonight, I did put in some time, and was able to make the SPICE Library compile on MacOS on Apple Silicon.</div>
<div class="">It had to do with the inclusion of the unistd.h header file that gives the access() function explicitly in the cspice/src/inquire.c</div>
<div class=""><br class="">
</div>
<div class="">I have written a short note on this. I have also include an Appendix in this Note on how to get the C Compiler environment going on Apple Silicon - because it was a bit of a learning curve for me, and it might help someone else.</div>
<div class=""><br class="">
</div>
<div class="">I have attached the Note, and a short file inquire.c.diff that you may use to quickly patch the inquire.c file (for Apple Silicon - if you were to make a SPICE library package for this hardware platform) as in:</div>
<div class="">patch inquire.c inquire.c.diff</div>

As of now, no work on an Apple ARM64 Mac by NAIF. We built and successfully tested CSPICE on the Raspberry Pi platform, so I believe an ARM64 build a solvable problem.<br class="">

What compile errors did you observe?<br class="">

<div class="x_PlainText">Hi all,<br class="">
<br class="">
I was wondering if any of us have successfully compiled and using CSPICE library on the new Apple Silicon (ARM64) M1 Macs?<br class="">
<br class="">
I got the gcc from Apple via Developer-Tools / XCODE package, but ran into certain compilation errors in the process. It would be good to know if anyone had already run into / solved issues on this front..<br class="">
<br class="">
Thanks & Regards,<br class="">
