Ubuntu ccmake issue: "ITK should not be configured & built in the ITK source directory"

[Kevin-Mattheus-Moerman]

Unable to run ccmake .., c configure and g generate

I'm using Ubuntu 18.04 and am trying to build ITK. I'm following the steps here (are these still up to date?): https://itk.org/Wiki/ITK/Getting_Started/Build/Linux. After creating a /bin directory and trying ccmake ..,and c to configure I get:

i.e. it says: "ITK should not be configured & built in the ITK source directory". So I am unable to proceed. Am I doing something wrong?

Steps to Reproduce

Expected behavior

Actual behavior

Unable to start with ccmake

Hi @Kevin-Mattheus-Moerman, thanks for reporting, the wiki is outdated (pinging @thewtex).
It is general good practice with any CMake project that the build (or bin) folder shouldn't be inside the source folder, but in a parallel folder. For example, the following will create ITK-src with the code and ITK-build in the same level:

git clone https://itk.org/ITK.git ITK-src
mkdir ITK-build; cd ITK-build
ccmake ../ITK-src

Great. Thanks that solved it.

@Kevin-Mattheus-Moerman the best getting started guide for C++ can be found in the ITK Software Guide here:

I added a historical note to the referenced wiki page for future reference.

That note looks mint!
