strange. I shall look into this later
I'm also hit by this issue. Here is the relevant bit of config.log: configure:5170: gcc -c -g -O2 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/sysprof-4 -pthread -I/usr/include/gmime-2.6 -D_LARGEFILE64_SOURCE -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/sysprof-4 -I/usr/lib64/libffi/include -I/usr/include/libmount -I/usr/include/blkid -pthread -I/usr/local/include/zdb -I/usr/include/zdb conftest.c >&5 In file included from conftest.c:31: /usr/include/zdb/ResultSet.h:185:1: error: unknown type name 'bool' 185 | bool ResultSet_next(T R); | ^~~~ /usr/include/zdb/ResultSet.h:29:1: note: 'bool' is defined in header '<stdbool.h>'; did you forget to '#include <stdbool.h>'? 28 | #include <time.h> 29 | /usr/include/zdb/ResultSet.h:203:1: error: unknown type name 'bool' 203 | bool ResultSet_isnull(T R, int columnIndex); | ^~~~ /usr/include/zdb/ResultSet.h:203:1: note: 'bool' is defined in header '<stdbool.h>'; did you forget to '#include <stdbool.h>'?
