Compilation error in Ubuntu 18.04

[jake-emerson]

Hi all, I'm having some trouble compiling DGtal. I built GraphicsMagick and libQGLViewer from sources. When running the following I don't get any errors:

cmake .. -DWITH_GMP=true -DWITH_ITK=true -DWITH_CAIRO=true -DWITH_QGLVIEWER=true -DWITH_MAGICK=true

However, if I have sudo apt install qt5-default then I can't install libQGLViewer (it requires Qt4).

With Qt4 I am getting the following error:

box:~/DGtal/build$ make

Is there some way out of this circular dependency problem? Is there a Dockerfile out there somewhere that will work to show a full installation example?

Thanks for the issue report. On my ubuntu18.04, I wasn't able to reproduce your issue. There may be a problem with your qglviewer version, how did you install it ?

On 18.04, the package version is 2.6.3 (working with qt4 and qt5). With that default package version, everything works fine (both qt5 and qt4) when building DGtal.

Can you please confirm me?

@jake-emerson Cannot test on 18.04 but back in the day you needed:

libqglviewer-dev-qt4, libqglviewer-headers, libqglviewer2-qt4

[jake-emerson]

Moving to version 2.6.3 of QGLViewer fixed my original error. I stuck with qt5. Thank you!

Now I have an issue with linking GraphicsMagick. I tested my install with the following:

> GraphicsMagick++-config --ldflags --libs
-L/usr/local/lib 
-lGraphicsMagick++ -lGraphicsMagick -ljbig -lwebp -lwebpmux -llcms2 -ltiff -lfreetype -ljpeg -lpng16 -lwmflite -lXext -lSM -lICE -lX11 -llzma -lbz2 -lxml2 -lz -lm -lpthread -lgomp

which seems to be fine. However, when I cmake DGtal it is unable to link properly.

I use the following for cmake:

> cmake .. -DWITH_GMP=true -DWITH_ITK=true -DWITH_EIGEN=true -DWITH_CAIRO=true -DWITH_QGLVIEWER=true -DWITH_MAGICK=true -DWITH_QT5=true -DCMAKE_BUILD_TYPE=debug -DVERBOSE=true -DDEBUG_VERBOSE=true /home/jake/DGtal

and make produces the following (truncated) error:

I compiled GraphicsMagick as follows:

wget https://sourceforge.net/projects/graphicsmagick/files/graphicsmagick/1.3.31/GraphicsMagick-1.3.31.tar.gz
tar -xzf GraphicsMagick-1.3.31.tar.gz
cd GraphicsMagick-1.3.31
./configure
make
make install
ldconfig /usr/local/lib

[jake-emerson]

Based on this PR I'm wondering if I should just switch to ImageMagick. https://github.com/DGtal-team/DGtal/pull/1366

[jake-emerson]

Scratch that. The FindMagick.cmake script seems to only look for GraphicsMagick: https://github.com/DGtal-team/DGtal/blob/1.0/cmake/FindMagick.cmake

[copyme]

@jake-emerson it works here (openSUSE 15.1) with GraphicsMagick 1.3.34

[copyme]

@jake-emerson I suggest compiling GraphicsMagick with --enable-shared --disable-static

[copyme]

@jake-emerson here you can see other compilation flags used by openSUSE package system. See lines starting from %configure.
