Re: [Qgis-user] Qgis failed to startup

Hi Christophe,

forwarding to dev list...

But do I see:
libQt5Widgets.so.5 ??

Are you aware that you are using Qt5.
Because building that is still experimental (but could be ok if you know
what you are doing).

Better to remove all the Qt5 stuff, and be sure that all your paths
point to the Qt4 versions of the libraries!
I think you mixup Qt4 and Qt5 versions of libs...

FYI, on Debian I start ccmake .. with the following:

# master
ccmake -DCMAKE_BUILD_TYPE=Debug
-DCMAKE_INSTALL_PREFIX=/home/richard/apps/qgis/master/debug
-DWITH_INTERNAL_QWTPOLAR=ON -DWITH_SERVER=TRUE -DBUILD_TESTING=FALSE ..

Regards,

Richard Duivenvoorde

Either run the installation

  make install
  qgis

Or run from the build folder (isolated, I use that for development)

  make
  ./output/bin/qgis

Not sure if it's this but it could potentially lead to qgis picking up
wrong libraries.

Cheers Matthias

I sometimes use 'strace' to see what happens when something stops.

So: try to build with debug info, that is use: -DCMAKE_BUILD_TYPE=Debug
or set it to Debug in ccmake..

export de LD_LIBRARY_PATH (as in your script)
And then
strace 
Maybe the segfault on the end reveals more info.

And if that fails, install gdb, and learn how to show stacktrace with
that
In short:
gdb qgis
(gdb) run
then after crash call backtrace:
(gdb) bt

Hope this helps

Richard

Hi Chris,

what distro/OS/version are you on?

(maybe you are better of on dev-list for such questions)

If you build like you do you can either run from build/output/bin directory.
OR you do make install, and if you did not point to a custom install
directory, I think you have todo 'sudo make install' because QGIS is
copying stuff to places where normal users have no write permission.

My take: install in your home dir (you can compile/run several versions
then):

-DCMAKE_INSTALL_PREFIX=/home/YOU/bin/qgis/2.1x

And create a little startup script like belose (take away stuff you do
not need, and fix paths for your situation)...:

# path to libs in install dir
# path to oracle lib
# path to grass70 lib
export
LD_LIBRARY_PATH=/home/richard/apps/qgis/master/debug/lib/:/home/richard/dev/oracle/12.1/instantclient_12_1:/usr/lib/grass70/lib

# passing ALL parameters to qgis bin
# eg to be able to call a certain translation
# qgis --lang nl
/home/richard/apps/qgis/master/debug/bin/qgis "$@"

Hope this helps,

Richard Duivenvoorde
