Hi Dears 3DSlicer developers

I want to build Slicer as mentioned in the site of [https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build\_Instructions](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build_Instructions).  
I do the following steps:

```

(base) [sn@localhost ~]$ 

```

So I have installed the packages mentioned in the site. Also, I check Qt installed usig qtdiag:

```
(base) [sn@localhost Slicer-SuperBuild-Debug]$ qtdiag 
Qt 5.9.7 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 7.3.0) on "xcb" 
OS: Fedora 25 (Workstation Edition) [linux version 4.8.6-300.fc25.x86_64]
...

```

I think that I installed Qt (5.9.7) correctly. At now, I enter the following commands:

```
(base) [sn@localhost ~]$ git clone https://github.com/Slicer/Slicer.git
...
(base) [sn@localhost ~]$ mkdir Slicer-SuperBuild-Debug
(base) [sn@localhost ~]$ cd Slicer-SuperBuild-Debug/

```

Why do I get this error?  
Please guide me.  
Thanks a lot.

Hi -

It looks like you cut the actual error message out of the build log. Run make again without the -j5 and it will stop on the actual error.

Hmm, thanks for the extra information. It looks like something in the way DCMTK is using [ICU](http://userguide.icu-project.org/icufaq). Maybe you need to install that too. If that works we can update the wiki to indicate it’s a requirement.
