If you install MySQL using a binary tarball distribution on HP-UX, you may run into trouble even before you get the MySQL distribution unpacked, as the HP-UX tar cannot handle long file names. This means that you may see errors when you try to unpack MySQL.

If this occurs, you must use GNU tar (gtar) to unpack the distribution.

There are a couple of small problems when compiling MySQL on HP-UX. Use gcc instead of the HP-UX native compiler, because gcc produces better code.

Use gcc 2.95 on HP-UX. Do not use high optimization flags (such as -O6) because they may not be safe on HP-UX.

The following configure line should work with gcc 2.95:

CFLAGS="-I/opt/dce/include -fpic" \
CXXFLAGS="-I/opt/dce/include -felide-constructors -fno-exceptions \
-fno-rtti" \
CXX=gcc \
./configure --with-pthread \
    --with-named-thread-libs='-ldce' \
    --prefix=/usr/local/mysql --disable-shared

The following configure line should work with gcc 3.1:

CFLAGS="-DHPUX -I/opt/dce/include -O3 -fPIC" CXX=gcc \
CXXFLAGS="-DHPUX -I/opt/dce/include -felide-constructors \
    -fno-exceptions -fno-rtti -O3 -fPIC" \
./configure --prefix=/usr/local/mysql \
    --with-extra-charsets=complex --enable-thread-safe-client \
    --enable-local-infile  --with-pthread \
    --with-named-thread-libs=-ldce --with-lib-ccflags=-fPIC
    --disable-shared
