failed to build due qt5 #32

Open KammutierSpule opened 7 years ago

KammutierSpule commented 7 years ago

I am using one of the latest Linux Mint (Ubuntu based) it fails to build while looking for qt libraries:

Package QtGui was not found in the pkg-config search path. Perhaps you should add the directory containing `QtGui.pc' to the PKG_CONFIG_PATH environment variable No package 'QtGui' found ... OSError: 'pkg-config QtGui QtWidgets QtCore QtOpenGL QtXml QtXmlPatterns QtNetwork --libs --cflags' exited 1: ...

It looks like it is expecting the 5 in the Qt5* library names. For instance, if I run in command line:

pkg-config Qt5Gui Qt5Widgets Qt5Core Qt5OpenGL Qt5Xml Qt5XmlPatterns Qt5Network --libs --cflags

it returns OK.

dvicini commented 7 years ago

I have exacty the same problem on my arch linux setup. I tried changing the loaded modules to the Qt5 modules (in mitsuba/data/scons/qt.py) and got it to compile. I can even run mtsgui. However, once I try to open a scene in it, I get mtsgui: relocation error: mtsgui: symbol _ZdlPvm, version Qt_5 not defined in file libQt5Core.so.5 with link time reference

I will investigate some more...

dvicini commented 7 years ago

UPDATE: I think downloading Qt5 manually is not necessary if you already installed it in your system. So you can leave out step 1.

Ok, so I figured it out now:

  1. First I installed Qt5 manually in a specific folder. In the config.py I then define

    QTDIR = '/hdd/local/qt5/5.9.1/gcc_64/'
QTINCLUDE = '/hdd/local/qt5/5.9.1/gcc_64/include/'

    (insert your path accordingly)

  2. Then in mitsuba/data/scons/qt5.py I changed all the validmodules (line 392) to include the version number, e.g. QtCore => Qt5Core

  3. I changed mitsuba/build/SConscript to load these modules by their updated names, i.e. I changed line 28 to qtEnv.EnableQt5Modules(['Qt5Gui', 'Qt5Widgets', 'Qt5Core', 'Qt5OpenGL', 'Qt5Xml', 'Qt5XmlPatterns', 'Qt5Network'])

  4. These changes should allow you to build everything. After building, I manually added the Qt5 library directory to the LD_LIBRARY_PATH, such that the correct dynamic libraries get loaded. With this I can now run mtsgui and render scenes from it

wjakob commented 7 years ago

Interesting -- especially since compiling Mitsuba with Qt5 currently works on Windows and MacOS. Do you think that this is a linux-specific requirement?

dvicini commented 7 years ago

It seems so, I don't have enough data to tell for sure though. Merlin compiled Mitsuba with Qt5 on OSX last week and that seemed fine (no changes required). I don't have a Windows setup to test, but I guess you have tested that.

I am not sure whether the Qt naming scheme can differ between distributions/package managers.

amyspark commented 7 years ago

@wjakob, I can confirm that Linux indeed needs this change, because of pkg-config's naming conventions: https://github.com/mitsuba-renderer/mitsuba/blob/46650b73a1064e0b074ef620c6da4963d7b17fa1/data/scons/qt5.py#L467 If one has Qt4 around in PATH, it returns those modules instead and thus breaks the build. However: changing module names e.g. QtGui -> Qt5Gui breaks -framework linking in MacOS, so...

lazysquid commented 7 years ago

I also have similar issue but quite different. It is weird cause although I have qt5, I also installed qt4 related libraries. 

Package QtWidgets was not found in the pkg-config search path.
Perhaps you should add the directory containing `QtWidgets.pc'
to the PKG_CONFIG_PATH environment variable
No package 'QtWidgets' found
OSError: 'pkg-config QtGui QtWidgets QtCore QtOpenGL QtXml QtXmlPatterns QtNetwork --libs --cflags' exited 1:

Currently I'm using ubuntu 16.04 and installed all dependencies.

amyspark commented 7 years ago

@FrostedPenguin, QtWidgets only appears in pkg-config in Qt5 (see qtbase5-dev). Anyway, I think I've fixed it in my fork (waiting for the Linux build to finish OK). I'll file a pull request when done.

hchoi405 commented 5 years ago

For reference, I successfully built mstgui in Ubuntu 18.04.1 with @amyspark's solution. One error I met was 'Qt5XmlPatterns not found' and resolved it by sudo apt install libqt5xmlpatterns5-dev

wuerzig commented 5 years ago

Confirmed @amyspark and @hchoi405 's solutions on Ubuntu 18 LTS

SilvioJin commented 5 years ago

Hi, I had the same problem and after doing what @dvicini suggested I tried to build running the following command:

QT_SELECT=qt5 scons -j8

but I got this errors now:

other (maybe) helpful info:

qmake --version

returns:

QMake version 3.0 Using Qt version 5.6.2 in /home/fen/anaconda3/envs/myProject/lib

added path such that echo $LD_LIBRARY_PATH

returns:

:/home/fen/anaconda3/envs/myProject/lib/pkgconfig/:/home/fen/anaconda3/envs/myProject/lib

Using Ubuntu 18.04.2 LTS.

Can anyone help?

Solved changed -std=c++11 into -std=gnu++11 in the config.py file

@SilvioJin 's solution confirm in Ubuntu 20.04. Just changed -std=c++11 into -std=gnu++11 in the config.py file
