<div class="">I am trying to compile the MEX files using "ft_compile_mex(true)“ on my Mac as described here: <a href="https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.fieldtriptoolbox.org%2Ffaq%2Fcompile%2F&data=05%7C01%7Cfieldtrip%40science.ru.nl%7Ce4fc6682164f41049ec608dbd5eaa6c1%7C084578d9400d4a5aa7c7e76ca47af400%7C1%7C0%7C638338976017550695%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=PKmWKNDw51sCCC4EUEZ78dhcVYRB7pYINRNf0%2BH%2BZw0%3D&reserved=0" originalsrc="https://www.fieldtriptoolbox.org/faq/compile/" shash="L/xwk+97bOx7kYYz20QS2TWka/q9jveDzlbSX1Wqn6iHfMbkjJAZxtYthgTh404l5E9kD+UXvgdkSMnHpWKg1/V9mEADM4HZVJzLjvRrR7ltyom3mtQlW/igtcJOcL0yJJQCUe+kQpMCDU1TenZP7JtyjWufvBg9xKzmYgX34/s=" originalsrc="https://www.fieldtriptoolbox.org/faq/compile/" shash="Q6IFZhmPPfSJ1gBEuiCa6gyQaU4tIiUwBNA2qXTWeosCaF4EQBEWAHYjWVaSSmE5UcQmthjy7UnzuttDViu3nICiK4Hv0xYiNaQTAh/udRKgPg0OzFpBAP06x+hnc6HJoDDzVd9vB3ELJMtbLM2oavV4ZxP4ycYOvyXyUjbrFDg=" class="">https://www.fieldtriptoolbox.org/faq/compile/</a>.
