Cannot install ROOT 6.10 on Cygwin

Hello. I’ve been trying to install ROOT version 6.10 on my Windows 10 64bit using Cygwin.
Here are the following commands I use:

git clone

mkdir build
cd build

cmake …/root -Dimt=OFF
make -j8

The additional “-Dimt=OFF” on the cmake is due to a problem I had with TBB. It did not seem to be able to install it, even after downloading it from the internet, so I set a variable to skip this step completely.
Currently, at “make -j8” or even “make -j2” the following error happens:

[ 27%] Performing configure step for 'LZ4'
[ 27%] Built target move_headers
CMake Error at /build/LZ4-prefix/src/LZ4-stamp/LZ4-configure-RelWithDebInfo.cmake:16 (message):
  Command failed: 2

   '/bin/sh' '-c' 'PREFIX=/build CMAKE_PARAMS='-DCMAKE_C_COMPILER="/usr/bin/cc" -DCMAKE_C_FLAGS=" -pthread" -DCMAKE_OSX_SYSROOT=""' make cmake'

In LZ4-configure-err.log is written:

make[3]: warning: jobserver unavailable: using -j1.  Add '+' to parent make rule.
make[3]: *** No rule to make target 'cmake'.  Stop.

Please note that I don’t have much experience with Cygwin or this programming language in general.
Is there any other information I can give about this problem?
Thank you in advance.


Cygwin is not officially supported, and CMake will most probably not produce correct makefiles… You can try the classic configure/make procedure. For example, something like:

../root/configure win32gcc [options]

But this might be failing too…

Chers, Bertrand.

That makes sense, I was not aware of that. I will download Ubuntu instead and run it there. Thank you.

You can also try running ROOT with the Ubuntu 16 docker image:
