Bug 692644 – dev-db/mysql-connector-c-8.0.17-r1: '#include <mysql/mysql.h>' fails without -I/usr/include/mysql

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Arfrever Frehtes Taifersar Arahesis 2019-08-20 19:07:48 UTC]

With dev-db/mysql-connector-c-6.1.11-r1:

$ gcc -c -x c - -o /tmp/test.o <<< '#include <mysql/mysql.h>'
$ gcc -c -I/usr/include/mysql -x c - -o /tmp/test.o <<< '#include <mysql/mysql.h>'
$ 


With dev-db/mysql-connector-c-8.0.17-r1:
$ gcc -c -x c - -o /tmp/test.o <<< '#include <mysql/mysql.h>'
In file included from /usr/include/mysql/mysql.h:81,
                 from <stdin>:1:
/usr/include/mysql/mysql_com.h:1005:10: fatal error: mysql/udf_registration_types.h: No such file or directory
 1005 | #include <mysql/udf_registration_types.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
$ gcc -c -I/usr/include/mysql -x c - -o /tmp/test.o <<< '#include <mysql/mysql.h>'
$ 


Reference to udf_registration_types.h is the only <>-style reference to an mysql-connector-c's own header amongst its headers:
$ grep -E '#[[:space:]]*include' $(find /usr/include/mysql -type f | sort)
/usr/include/mysql/mysql.h:#include <stdbool.h>
/usr/include/mysql/mysql.h:#include <stddef.h>
/usr/include/mysql/mysql.h:#include <sys/types.h>
/usr/include/mysql/mysql.h:#include <windows.h>
/usr/include/mysql/mysql.h:#include <winsock2.h>
/usr/include/mysql/mysql.h:#include "field_types.h"

/usr/include/mysql/mysql/client_plugin.h:#include "plugin_auth_common.h"
/usr/include/mysql/mysql/plugin_auth_common.h:#include <windows.h>
/usr/include/mysql/mysql/udf_registration_types.h:#include <stdbool.h>
/usr/include/mysql/mysql_com.h:#include <stdbool.h>
/usr/include/mysql/mysql_com.h:#include "my_command.h"
/usr/include/mysql/mysql_com.h:#include "my_io.h"
/usr/include/mysql/mysql_com.h:#include <stdbool.h>
/usr/include/mysql/mysql_com.h:#include <mysql/udf_registration_types.h>
$ 


If this reference is changed to ""-style, then '#include <mysql/mysql.h>' would work even without -I/usr/include/mysql:
[[[

+++ /usr/include/mysql/mysql_com.h

 /* Include the types here so existing UDFs can keep compiling */

]]]

$ gcc -c -x c - -o /tmp/test.o <<< '#include <mysql/mysql.h>'
$ gcc -c -I/usr/include/mysql -x c - -o /tmp/test.o <<< '#include <mysql/mysql.h>'
$
