2.12.5.2. HP-UX Version 11.x Notes

Because of some critical bugs in the standard HP-UX libraries, you should install the following patches before trying to run MySQL on HP-UX 11.0:

PHKL_22840 Streams cumulative
PHNE_22397 ARPA cumulative

This solves the problem of getting EWOULDBLOCK from recv() and EBADF from accept() in threaded applications.

If you are using gcc 2.95.1 on an unpatched HP-UX 11.x system, you may get the following error:

In file included from /usr/include/unistd.h:11,
                 from ../include/global.h:125,
                 from mysql_priv.h:15,
                 from item.cc:19:
/usr/include/sys/unistd.h:184: declaration of C function ...
/usr/include/sys/pthread.h:440: previous declaration ...
In file included from item.h:306,
                 from mysql_priv.h:158,
                 from item.cc:19:

The problem is that HP-UX does not define pthreads_atfork() consistently. It has conflicting prototypes in /usr/include/sys/unistd.h:184 and /usr/include/sys/pthread.h:440.

One solution is to copy /usr/include/sys/unistd.h into mysql/include and edit unistd.h and change it to match the definition in pthread.h. Look for this line:

extern int pthread_atfork(void (*prepare)(), void (*parent)(),
                                          void (*child)());

Change it to look like this:

extern int pthread_atfork(void (*prepare)(void), void (*parent)(void),
                                          void (*child)(void));

After making the change, the following configure line should work:

CFLAGS="-fomit-frame-pointer -O3 -fpic" CXX=gcc \
CXXFLAGS="-felide-constructors -fno-exceptions -fno-rtti -O3" \
./configure --prefix=/usr/local/mysql --disable-shared

If you are using HP-UX compiler, you can use the following command (which has been tested with cc B.11.11.04):

CC=cc CXX=aCC CFLAGS=+DD64 CXXFLAGS=+DD64 ./configure \
    --with-extra-character-set=complex

You can ignore any errors of the following type:

aCC: warning 901: unknown option: `-3': use +help for online
documentation

If you get the following error from configure, verify that you don't have the path to the K&R compiler before the path to the HP-UX C and C++ compiler:

checking for cc option to accept ANSI C... no
configure: error: MySQL requires an ANSI C compiler (and a C++ compiler).
Try gcc. See the Installation chapter in the Reference Manual.

Another reason for not being able to compile is that you didn't define the +DD64 flags as just described.

Another possibility for HP-UX 11 is to use the MySQL binaries provided at https://dev.mysql.com/downloads/, which we have built and tested ourselves. We have also received reports that the HP-UX 10.20 binaries supplied by MySQL can be run successfully on HP-UX 11. If you encounter problems, you should be sure to check your HP-UX patch level.
