Hi,
I'm trying to compile Therion (sources from github) on Ubuntu 16.04 for the first time. After installing several missing libraries I'm getting the following error: make[1]: Entering directory '/home/rodrigo/devel/therion/loch' c++ -o ./loch -Wall ./lxR2P.o ./lxTR.o ./lxOGLFT.o ./lxSetup.o ./lxRender.o ./lxWX.o ./lxImgIO.o ./lxLRUD.o ./lxFile.o ./lxSTree.o ./lxData.o ./lxMath.o ./lxSView.o ./lxSScene.o ./lxGUI.o ./lxGLC.o ./lxOptDlg.o ./lxAboutDlg.o ./lxPres.o ./img.o -lwx_gtk2u_gl-3.0 -L/usr/lib/x86_64-linux-gnu -pthread -lwx_gtk2u_xrc-3.0 -lwx_gtk2u_html-3.0 -lwx_gtk2u_qa-3.0 -lwx_gtk2u_adv-3.0 -lwx_gtk2u_core-3.0 -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0 -L/usr/lib/vtk-5.10 -lvtkHybrid -lvtkImaging -lvtkIO -lvtkGraphics -lvtkFiltering -lvtkCommon -lfreetype -lGLU -lGL -lpthread -lX11 -lz -s /usr/bin/ld: ./lxRender.o: undefined reference to symbol 'png_write_row@ @PNG12_0' //lib/x86_64-linux-gnu/libpng12.so.0: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status Makefile:162: recipe for target 'loch' failed make[1]: *** [loch] Error 1 make[1]: Leaving directory '/home/rodrigo/devel/therion/loch' Makefile:202: recipe for target 'loch/loch' failed make: *** [loch/loch] Error 2 The problem here is that libpng12.0-dev is already installed. After some research I believe this might be a problem related to missing symbols related to bad ordering of library inclusion: http://stackoverflow.com/questions/19901934/strange-linking-error-dso-missing-from-command-line How can I fix this?
