Hello,
I am trying to build Ugene from source (because i want it to work with Cuda).

Something goes wrong with the Smith-Waterman plugin that makes the build fail, it looks like a path issue:

qmake -r
Code:

...
Reading /home/persalteas/ugene-1.30.0/src/plugins/smith_waterman/smith_waterman.pro
QDir::mkpath: Empty or null file name
WARNING: nvzz: Cannot access directory ''
... 

And if i try to build it anyway, it works well for a while, and finally fails on the Smith-Waterman plugin again:

make
Code:

...

nvcc -m 32 -g -G -Xcompiler -Zi,-MD -Xlinker /DEBUG -c -I -Isrc -I_tmp -I../../include -I../../corelibs/U2View/_tmp -L -lcudart -o _tmp/obj/release/sw_cuda.o src/sw_cuda.cu
nvcc warning : Compiling in the 32-bit mode when the host compiler targets x86 or x86_64 is no longer supported on Linux
gcc-6: error: unrecognized command line option ‘-Zi’; did you mean ‘-Z’?
Makefile.Release:292: recipe for target '_tmp/obj/release/sw_cuda.o' failed
 

I tried to edit src/plugins/smith_waterman/smith_waterman.pri to force -m 64 (removed the warning about 32 bit mode) and to replace -Zi by -Z. The compilation went a bit further, but failed again:

Code:

make[1] : entering directory « /home/persalteas/ugene-1.30.0/src/plugins/smith_waterman »
/usr/lib/qt5/bin/qmake -o Makefile smith_waterman.pro
QDir::mkpath: Empty or null file name
WARNING: nvzz: Cannot access directory ''
 

and then linking fails.


Additional info:
- Issue observed on two different machines:

• a Centos 7 workstation with 8 core Intel Xeon, GCC 5, Nvidia driver 390, CUDA 9.2,
• an Ubuntu 18.04 with 16-core AMD Ryzen, GCC 6, Nvidia 390 driver, CUDA 9.1.

- Used the source of UGENE 1.30, downloaded from here : ugene.unipro.ru/downloads/ugene_get_latest_source.html


Any idea what to do ? Any help would be appreciated, thanks in advance !

Thank you, i am waiting to hear from you, then. 

Hi again!

I'm writing to inform you that we're still working on the issue. We fixed the compilation issues, but we have some problems with testing the issue on a Linux machine. Hopefully, we'll solve them in the nearest future.

Sorry again for the delay!

The latest source version with the issue fix is available on GitHub.

Please inform us, if it works fine on your system also.

Hi Louis!

We use Qt Creator on Linux, so you can try the steps below.
Your environment and hardware may be some different, but I think it’s not very important.

Anyway, our CUDA platform is the following:
1)      X64 desktop with ASUS motherboard, Intel processor, 16 Gb memory, 1 Tb HDD
2)      Tesla K20c CUDA card
3)      All video is processed by embedded Intel graphic card
4)      CUDA card is used only for accelerating of the numeric computations. More over the card hasn’t any video output (some X11 setting is needed to setup).
5)      The Linux version is Ubuntu 18.04 which was installed on clean HDD from desktop variant of the Ubuntu 18.04 iso distribution.
6)      CUDA version (nvcc –version)
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2018 NVIDIA Corporation
Built on Wed_Apr_11_23:16:29_CDT_2018
Cuda compilation tools, release 9.2, V9.2.88
7)      Nvidia driver version (output of the nvidia-smi command)


As I mentioned, we use Qt Creator on Linux, and we used the following steps to set the CUDA environment:
1) In the main qt creator window view click the button "Projects"
2) Build settings windows is opened. You need just add three env vars for CUDA:
    CUDA_HOME=/usr/local/cuda
    CUDA_INC_PATH=/usr/local/cuda/include
    CUDA_LIB_PATH=/usr/local/cuda/lib64
3) Another solution is to set these vars as global, for example in ~/.bashrc (before build):
    export CUDA_HOME=/usr/local/cuda
    export CUDA_INC_PATH=/usr/local/cuda/include
    export CUDA_LIB_PATH=/usr/local/cuda/lib64

Both solution works for me
Please don't forget to add cuda to PATH and LD_LIBRARY_PATH global vars too.

Thanks,
--Igor.

Hi Louis!

Can you try to add CONFIG+=x64 to qmake command? And rebuild Ugene.
As I know cuda needs x64-bit compiler option.
So, if you want to have cuda support you need x64 compilation

Thanks,
Igor.

Hi Igor,

Thanks a lot, the compilation successfully finished ! 

Unfortunately, Ugene fails to start:
Code:

ugene -ui 

I get the "Ugene crash reporter" window with the following message:
Code:

Any idea ?

Hi Igor,

I restarted all the installation from scratch to give you an exhaustive description of what i did and.... it worked !

I think i know what the issue was : Cuda is not compatible with GCC/G++ 7 on Ubuntu 18.04 (yet). I think i used the 7 without noticing in my previous compilation.

As i did the work of listing everything, let's post it for the case someone would have the same issue:

- Do a fresh install of Ubuntu 18.04 (minimal install is enough).
- Do your updates (sudo apt update, sudo apt upgrade)
- Install libraries and building packages: sudo apt install build-essential git htop zlib1g-dev qt5-default qttools5-dev-tools qtscript5-dev libqt5svg5-dev libqt5webkit5-dev
- Install nvidia driver : From control center > additional drivers > nvidia-driver-390
- Install Cuda : sudo apt install nvidia-cuda-toolkit
- Install GCC 6 and set it by default:
Code:

sudo apt install gcc-6 g++-6
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 10
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-6 10
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 20
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 20
sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 30
sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 30
sudo update-alternatives --set cc /usr/bin/gcc
sudo update-alternatives --set c++ /usr/bin/g++
sudo update-alternatives --config gcc
sudo update-alternatives --config g++ 

- Then, create a directory and cd to it (mkdir -p ~/Sources & cd ~/Sources)
- Clone Ugene : git clone https://github.com/ugeneunipro/ugene.git
- cd ugene
- nano src/ugene_globals.pri and edit the line "isEmpty(UGENE_CUDA_DETECTED) : UGENE_CUDA_DETECTED = 0", replace 0 by 1
- return to Sources/ugene
- qmake -r CONFIG+=x64 (a warning about paths still appears after reading Smith-Waterman .pro)
- make -j 16 release
- sudo make install
- ugene -ui


And everything works !!    This topic can be marked [Solved].
Thanks a lot !

Louis
