Build environment in Ubuntu 14.04 issue

[ajukraine]

I can't properly configure my build environment. Installed Qt5.6 and still getting linker errors (with g++-4.8). Can you describe your build environment (especially Qt5+ details)?

[angrylinuxuser]

are you using some kind of ide to build or are you building by hand?

[ajukraine]

I don't think this matter whether I use QtCreator or just qmake/make. Tried both of them, got same linker error list.

[angrylinuxuser]

Could you post those linker errors? That can shed some light on your problem (im thinking you are missing some dev packages)

[BOSSoNe0013]

Hi, except qtbase5-dev, there's no requirement for Qt5. As said by @angrylinuxuser, provide your linker output and we will be able to help you.

[angrylinuxuser]

quick look at project file: -lGL -lGLU -lXext -lX11 -lXfixes so you need all those dev packackes besides qt

This is what I get, when compiling with latest installed qtbase5-dev package (5.2.1+dfsg-1ubuntu14.3):

you need qt5.5+ and you have 5.2 Go to http://www.qt.io/download/ and get it from there since i doubt that 14.04 will have 5.5 in repos. ok nvm this commnet.

[ajukraine]

I guess, I fixed that temporarily. The Qt project file contains default path to the library folder:

LIBS +=  -lGL -lGLU -lXext -lX11 -lXfixes -L/usr/lib/x86_64-linux-gnu/

But in my case (manual Qt distribution) I should have change that to:

LIBS +=  -lGL -lGLU -lXext -lX11 -lXfixes -L/home/ajukraine/Qt/5.6/gcc_64/lib

well you can just export LD_LIBRARY_PATH=/path/to/qt5.6 then run make. should work. or is it export LIBRARY_PATH? one of those
