Re: [Qgis-user] How to build qgis

[Richard Duivenvoorde via QGIS-User]

Hi Deimer,

You did not provide very much information :-)

But from your second link I concluded that you are building on Windows x?

Not so many Windows users (OR developers) build QGIS their selves (me included) 
on their own machines. On Linux it is a lot easier as the most lib will be 
provided by your distro. On Windows it is (for what I know) best to stick to 
the Osgeo4w packages.
Note that building a complex beast as QGIS (+needed modules/libs) isn't easy, 
so unless you have experience or really want to build experience,  I think it 
is best to try to compile the same way as the Windows packagers do

IF you need help on Win builds, it is better to sent an email to the Qgis-dev 
list AND provide more information (what tools are you using, what errors do you 
see, what Windows version etc etc)...

Regards,

Richard Duivenvoorde

Is there any updated documentation to make the build successful?

Thank so much for your attention.

Re: [Qgis-user] How to Build QGIS from source in Centos 6?

[童言]

THANKS. But If I try to build QGIS from source in Centos 6 with Qt4 
dependencies, what are the substitutes for these packages ' qt5-qtwebkit-devel 
qt5-qtlocation-devel qt5-qttools-static qt5-qtscript-devel qca-qt5-devel 
python3-qt5-devel python3-qscintilla-qt5-devel qscintilla-qt5-devel 
python3-qscintilla-devel python3-qscintilla-qt5 qt5-qtsvg-devel 
qt5-qtxmlpatterns-devel' with Qt4 dependencies? For example, I can't just 
relplace qt5-qtsvg-devel by qt4-qtsvg-devel because there does not exist 
qt4-qtsvg-devel.

Hi,

Short answer: don't! QGIS 2.0.1 is really old, a lot of bugs have been
fixed since and a lot of new features have been introduced.

Long answer:

QGIS 2.0.1 is really old. It is not Qt5 compatible. If you want Qt5
support (which also means that you will have trouble to get your plugins
to work) you will need a newer QGIS version (and apparently build
dependencies like the ones you mention below).

You can also try to build with Qt4 dependencies. QGIS 2.0.1 INSTALL
states Qt >= 4.5 so it should be compatible with the (also really old)
Qt 4.6 version.

[Qgis-user] How to Build QGIS from source in Centos 6?

[童言]

I can't find the INSTALL guide on how to compile QGIS 2.0.1 from source for 
Centos platform. If I just do this on Centos 6 platform according to the guide 
for Fedora Linux, such as: 


dnf install qt5-qtwebkit-devel qt5-qtlocation-devel qt5-qttools-static 
qt5-qtscript-devel qca-qt5-devel python3-qt5-devel python3-qscintilla-qt5-devel 
 qscintilla-qt5-devel python3-qscintilla-devel python3-qscintilla-qt5 clang 
flex bison geos-devel gdal-devel sqlite-devel libspatialite-devel 
qt5-qtsvg-devel qt5-qtxmlpatterns-devel spatialindex-devel expat-devel 
proj-devel qwt-devel gsl-devel postgresql-devel.




I find there are no packages about qca-qt5-devel, python3-qt5-devel, 
python3-qscintilla-qt5-devel, qscintilla-qt5-devel, python3-qscintilla-devel 
and python3-qscintilla-qt5 for Centos 6, so what should I do now?
