Ubuntu trusty, cannot compile

[ouboub]

Hi

I have installed
cmake-data
cmake
libboost1.54-dev
libboost-program-options1.54-dev
libboost-program-options-dev
libpoppler-qt5-1
autoconf-archive
libboost-test1.55.0
libboost1.55-dev
libboost-test1.55-dev
libxkbcommon-x11-0

but when I follow the installation instruction
running
cmake ../
gives
CMake Error at cmake/external_libraries.cmake:42 (find_package):
By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5Core", but
CMake did not find one.

Could not find a package configuration file provided by "Qt5Core"
(requested version 5.1.1) with any of the following names:

Qt5CoreConfig.cmake
qt5core-config.cmake

Add the installation prefix of "Qt5Core" to CMAKE_PREFIX_PATH or set
"Qt5Core_DIR" to a directory containing one of the above files. If
"Qt5Core" provides a separate development package or SDK, be sure it has
been installed.
Call Stack (most recent call first):
CMakeLists.txt:47 (include)

-- Configuring incomplete, errors occurred!
See also "/home/oub/ALLES/src/dspdfviewer/build/CMakeFiles/CMakeOutput.log".

I have libqt5core5a 5.2.1
installed.

What is the problem?

thanks

Hello Uwe,

it seems you have only installed the Qt libraries (required to run already-compiled programs), but not the headers/development files needed to compile some yourself.

A search in the ubuntu package directories suggests you should try installing qtbase5-dev.

You may need more than this one package to compile yourself. Please take a look at the dependency list inside travis.yml, which is used during the continuous integration build.

As a third option, you can use the pre-built binary from the ppa. If there is an audience for it; I'll upload the newest version to the trusty one.

I hope this helps, and sorry for the delay.

Hi Danny,

thanks for your answer!

1. I installed qtbase5-dev. The cmake gives the following error:
   CMake Error at cmake/external_libraries.cmake:47 (find_package):
   By not providing "FindQt5LinguistTools.cmake" in CMAKE_MODULE_PATH this
   project has asked CMake to find a package configuration file provided by
   "Qt5LinguistTools", but CMake did not find one.

Could not find a package configuration file provided by "Qt5LinguistTools"
with any of the following names:

Qt5LinguistToolsConfig.cmake

I searched for qt5linuisttool, but seems that qttools5-dev-tools was the package needed, but no, compilations resulted in the same error. So I am stuck again. I think it would be good to add the required packages to the INSTALL file, if possible

• 1. I found and installed the binaries and run into a problem which I will report in a different issue, because it has to do with the functionality.

Hello Uwe,

I'm not sure how to best solve this, so I'll just give my comments, maybe we'll come to an idea together.

I think it would be good to add the required packages to the INSTALL file, if possible

While I admit that the INSTALL file is a bit outdated (it lists the now-default-and-working-fine Qt5 support as experimental) I don't think listing required package names is possible, since they will be different for each distribution. Essentially all that can be said distribution-agnostic is something along the lines of "You need Boost, CMake, Qt5 and poppler-qt5, each including the development headers".

The INSTALL file mentions that the website contains specific install instructions per distribution, and I checked that the Ubuntu trusty information there still works for getting the binary. You are correct in that it does not install the build-from-source-dependencies, even though the debian/control file contains the needed information.

Having said that, if you have a concrete idea how to improve the INSTALL file, please send a pullrequest with your suggested change.

I found and installed the binaries and run into a problem which I will report in a different issue, because it has to do with the functionality.

Thank you for keeping the discussions separate, it is much appreciated. I will post there aswell.

Danny
