How to build Qt 5.2 on Solaris 10? - solaris

Question

The Qt page does not list pre-compiled Qt 5 packages for Solaris. Searching around, it does not seem to be included in the popular package repository OpenCSW, either. Some google hits suggest that building Qt 5 under Solaris involves some work under Solaris 10.
Thus my question: How to build Qt 5.2 under Solaris 10?

Answer 1

Basically it is:
cd qt-everywhere-opensource-src-5.2.0
./configure -prefix $MY_PREFIX -opensource -confirm-license -nomake tests \
-R /opt/csw/lib/64 -R /opt/csw/X11/lib/64 -qt-xcb -platform solaris-g++-64 \
-verbose
gmake -j16
gmake -j16 install
plus some adjustments because Qt 5 does not seem to be used on
Solaris much, yet.
Adjustments
Obtain the source
wget http://download.qt-project.org/official_releases/qt/5.2/5.2.0/single/qt-everywhere-opensource-src-5.2.0.tar.gz
md5sum qt-everywhere-opensource-src-5.2.0.tar.gz
228b6384dfd7272de00fd8b2c144fecd qt-everywhere-opensource-src-5.2.0.tar.gz
If the system does not habe md5sum you can use openssl md5 filename instead.
Install dependencies
I recommend to use OpenCSW because we need some dependencies to build Qt. The most important ones are:
CSWlibxcbdevel
CSWlibicu-dev # soft-dependency
CSWgcc4g++
CSWgmake
I suggest to use GCC to compile Qt. I am not aware of any advantages using the C++ compiler from Solaris Studio. On the contrary, the level of C++/STL support of this compiler may be not sufficient for a lot of use cases.
Setup environment
Make sure that you environment is clean. That means that /opt/csw/bin comes first and no LD_LIBRAYR_PATH* variables are set.
To simplify things it is probably a good idea that some directories are removed from PATH. For example such that no cc, CC commands from a Solaris Studio installation are accidentally picked up (e.g. during the compile of a bundled 3rd party component.
Adjust the specs
The software under /usr/sfw is just too outdated. /opt/csw from OpenCSW is a better replacement. Then the X-Open version is not sufficient for some used system functions.

Fix the shell
Solaris comes with a /bin/sh that violates POSIX to an extend such
that Qt's configure scripts and even shell-code in qmake-generated
code fails.
POSIX does not specify that /bin/sh has to be conforming it just specifies that the system must have a conforming shell available 'somewhere'. On Solaris it is e.g. under /usr/xpg4/bin/sh. The portable way to get a conforming shell is to search for it in the directories returned by getconf CS_PATH ...
Anyways, my choice for Solaris is to just use /usr/bin/bash:

Fix the ICU test
Solaris 10 comes with an outdated libicu - which is missing features Qt 5 needs. Thus, we simply extend the icu-test. Then either no ICU-support is build or proper one in case we install a recent libicu e.g. via OpenCSW.

Include/type/usage fixes
The uname() function is activated via a CPP construct on Solaris
and is declared in that header:

Under Solaris uid_t has an 'unexpected' sign (-> Werror). Casting it to ssize_t should be a portable and safe choice:

Similar issue with threading code (Werror because of sign-mismatch in pointer cast). Casting to size_t should be a portable safe choice:

The struct in_addr has a struct as first attribute on Solaris, thus gives a warning with GCC when initializing with {0} - thus, yields an error during Qt-compile:

The header comment of X11/Xutil.h lists X11/Xutil.h as dependency, and indeed, without that include some declarations are missing under Solaris.

The X11/extensions/XIproto.h is not C++-safe under Solaris. That means it contains struct members names class. Fortunately, the header does not seem to be used in that code.

The pow() function has some overloads as specified in the C++ standard which introduce ambiguities under Solaris. Fixing the types like this should be portable and safe:

Fix deep mkdir
Qt does a 'deep' mkdir() (e.g. something like mkdir -p for e.g. creating a directory hierarchy, e.g. ~/.config/company/product. The Qt 5.2 algorithm may abort too soon on Solaris if an existing directory is located inside a non-writable NFS mounted parent - because in that case Solaris returns EACCESS instead of EEXIST.

Temporary files
Solaris also does not have mkdtemp():

const size_t length = strlen(templateName);
Pthreads
Solaris does not have pthread_get_stacksize_np (the _np suffix stands for non-portable).
Solaris has another function for getting stack-address/size values. My attempt:

I recommend a careful review of that code because my Qt-code does not use that Qt-module, thus, I did not test it much.
XKB extension
Qt 5 seems to heavily rely on the XKB extension. It seems that you can't build Qt 5 without XKB support. It comes bundled with xkbcommon.
First, make sure that it finds the right XKB database. Otherwise keyboard input does not work at all in your Qt programs!
Solaris does not have the default value /usr/share/X11/xkb. It has instead:
/usr/X11/lib/X11/xkb
/usr/openwin/lib/X11/xkb
But I havn't had luck with those - xkbcommon simply could not find any components with those.
I ended up with copying /usr/share/X11/xkb from a cygwin distribution to a custom path and configuring that as XKB database.
Whatever XKB you choose you have to configure it:
--- a/qtbase/src/3rdparty/xkbcommon.pri
+++ b/qtbase/src/3rdparty/xkbcommon.pri
## -1,7 +1,12 ##
QMAKE_CFLAGS += -std=gnu99 -w
INCLUDEPATH += $$PWD/xkbcommon $$PWD/xkbcommon/src $$PWD/xkbcommon/src/xkbcomp
+solaris-g++-64 {
+DEFINES += DFLT_XKB_CONFIG_ROOT='\\"/MY/XKB/CHOICE\\"'
+} else {
DEFINES += DFLT_XKB_CONFIG_ROOT='\\"/usr/share/X11/xkb\\"'
+}
### RMLVO names can be overwritten with environmental variables (See libxkbcommon documentation)
DEFINES += DEFAULT_XKB_RULES='\\"evdev\\"'
For testing it also make sense to check for NULL values in error message parameters:
--- a/qtbase/src/3rdparty/xkbcommon/src/xkbcomp/xkbcomp.c
+++ b/qtbase/src/3rdparty/xkbcommon/src/xkbcomp/xkbcomp.c
## -68,8 +68,11 ## text_v1_keymap_new_from_names(struct xkb_keymap *keymap,
log_err(keymap->ctx,
"Couldn't look up rules '%s', model '%s', layout '%s', "
"variant '%s', options '%s'\n",
- rmlvo->rules, rmlvo->model, rmlvo->layout, rmlvo->variant,
- rmlvo->options);
+ rmlvo->rules, rmlvo->model,
+ rmlvo->layout ? rmlvo->layout : "(NULL)",
+ rmlvo->variant ? rmlvo->variant : "(NULL)",
+ rmlvo->options ? rmlvo->options : "(NULL)"
+ );
return false;
}
There is also the possibility that your XServer does not even support the XKB extension. Again, I don't know if Qt 5 can be configured with disabled-XKB-support under X.
You can check your X-server like this:
xprop -root | grep xkb
Or call a random xkb-program, e.g.:
xkbvleds
Such call should not result in an error like:
Fatal Error: Server doesn't support a compatible XKB
In case your XServer does not have XKB - Qt programs are likely to segfault. Qt does not seem to really check for XKB support. It does not seem to have a fallback mechanism when XKB is not usable.

make install
A gmake install surprisingly triggers the compilation of several modules not yet compiled. Thus it make sense to execute it in parallel:
$ gmake -j16 install
(assuming that your system has a sufficient number of cores)
QtHelp
The bundled QtHelp module is not build/installed with the main compile/install steps.
To fix that:
cd qttools
PATH=$MY_PREFIX/bin:$PATH qmake
gmake
gmake install
Open issues
when using a remote Cygwin-X connection some colors are weird - e.g. the standard widget-gray is some light-light-blue - any ideas where to start to look for that?
QtSVG is successfully built but displaying a small SVG (e.g. inside a QLabel) hangs the dialog - a truss -u : shows function calls inside libm/QtWidget - perhaps the system is just way too slow and/or some code-path is not optimized on Solaris/in combination with a X-forwarding over ssh
a Qt-Program prints on startup: Qt Warning: Could not find a location of the system's Compose files. Consider setting the QTCOMPOSE environment variable. - no idea what feature this is about
Conclusion
With those adjustments 'normal' Qt programs (without QtSvg) compile
and run fine under Solaris 10.
