#112 Compile Error Sun Solaris and HP-UX

[Wilfried Brunken]

Hi,
we have many UNIX-Servers and kompiled QT-Lib &
XXDIFF on SuSe LINUX 8 and IBM-AIX 4.3 successfully
with the GCC 2.95.
But we problems on Sun and HP:

Sun Solaris

GCC 2.95.3

for solaris bug: you need to ifdef.

for hp/ux bug: you need to include the file that declares
snprintf.

i have access to neither of these platforms at the moment...
feel free to send me a patch.

cheers,

Hello.

I have compiled on many platforms. Let me detail the least
common denominators for you.

You'll need to make sure you use QT 3.x. QT 2.x did
not work with xxdiff-2.9.2, on any platforms. In paticular, I
have been using QT-3.1.2. I have tried QT-2.x and the
compile blows up in a similar manner as you describe.

Also, you'll need to use/try the GCC-3.2.3 compiler on some
platforms, as it has many fixes. GCC-2.95.2 works fine on
Solaris and Linux, but the C++ compiler functionality for other
platforms like HP-UX,Tru64,AIX etc is not fully fixed/operation
until you move into the more recent GCC compilers.

Also, don't bother trying to use the native compilers unless
you are on Solaris. This is a real pain, and will get you
nowhere, unless you want to spend weeks porting the QT lib.
If you could get the QT libs ported to use all major unix
vendors compilers, the xxdiff port would be trivial, but we're
not there yet. This is my advice from a seasoned (10/15+
yrs) porter/developer.

I don't understand the rant about Qt not building with Unix
native compilers. It does build on HP-UX, Irix, Tru64,
Solaris, AIX and other Unix platforms using the native
compiler. In many cases you do need a recent version or a
properly patched compiler or system, but that's about it. Qt
builds out of the box.

About HP-UX 10.20: There's no snprintf() available on this
platform:

Either use sprintf() instead and ignore related security
issues, or copy a custom snprintf() function from some other
project:
