Using GEOIP_INDEX_CACHE on some older versions of libGeoIP (e.g. 1.5.0
which is the default version on CentOS 7) leads to "Error reading file"
error while opening completely valid GeoIP.dat:
# cat test.c
#include <stdio.h>
#include "GeoIP.h"
int main(void) {
GeoIP *g;
g = GeoIP_open("/tmp/GeoIP.dat", GEOIP_INDEX_CACHE);
if (g == NULL) {
printf("error!\n");
}
GeoIP_delete(g);
exit(0);
}
# cc -lGeoIP -o test test.c
# ./test
Error reading file /tmp/GeoIP.dat
error!
# sed -i -e 's,GEOIP_INDEX_CACHE,GEOIP_MEMORY_CACHE,' test.c
# cc -lGeoIP -o test test.c
# ./test
# geoiplookup -f /tmp/GeoIP.dat -v 8.8.8.8
