Now I get:
/usr/pkg/java/sun-6/bin/java: Unknown elf note type 1: [namesz=8, descsz=0
name= 01.01]
And for a native mysqld I get this when starting the rc.d script:
/usr/pkg/bin/my_print_defaults: Unknown elf note type 1: [namesz=5, descsz=0
name= 1.00]
/usr/pkg/libexec/mysqld: Unknown elf note type 1: [namesz=5, descsz=0 name=
1.00]
See kern/46761 for other issues with older NetBSD binaries but in my case it
was a
binary build for the same OS version:
/usr/pkg/bin/my_print_defaults: ELF 32-bit LSB executable, Intel 80386, version
1 (SYSV), dynamically linked (uses shared libs), for NetBSD 6.0, stripped
/usr/pkg/libexec/mysqld: ELF 32-bit LSB executable, Intel 80386, version 1
(SYSV), dynamically linked (uses shared libs), for NetBSD 6.0, stripped
From readelf -a /usr/pkg/libexec/mysqld:
