Several errors about missing GNU extensions like getline() and strndup(): > strndup from V8: char* strndup(char* str, size_t n) { // Stupid implementation of strndup since macos isn't born with // one. size_t len = strlen(str); if (len <= n) return StrDup(str); char* result = new char[n+1]; size_t i; for (i = 0; i <= n; i++) result[i] = str[i]; result[i] = '\0'; return result; } > warning: implicit declaration of function ‘getline’ > error: ‘strndup’ was not declared in this scope > for getline do you mind trying #define _GNU_SOURCE 1 before #include <stdio.h> in the offending files?
