16.6 Particular systems

On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler:

./configure CC="cc -Ae -D_XOPEN_SOURCE=500"

and if that doesn't work, install pre-built binaries of GCC for HP-UX.

On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its <wchar.h> header file. The option ‘-nodtk’ can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try

./configure CC="cc"

and if that doesn't work, try

./configure CC="cc -nodtk"

On Solaris, don't put /usr/ucb early in your PATH. This directory contains several dysfunctional programs; working variants of these programs are available in /usr/bin. So, if you need /usr/ucb in your PATH, put it after /usr/bin.

On Haiku, software installed for all users goes in ‘/boot/common’, not ‘/usr/local’. It is recommended to use the following options:

./configure --prefix=/boot/common
