Cmake can't find X11 libs

Question

I'm trying to compile a GUI-based package on my RHEL 7.2 (XFCE environment). But every time I run cmake .. , it fails with the report:

[user@localhost build]$ cmake ..
-- BUILD TYPE set to the default type:  'Release'
-- Setting fallback CUDA_ARCH=35
-- Setting cpu precision to double
-- Setting gpu precision to single
-- Using cuda wrapper to compile....
-- Cuda version is >= 7.5 and single-precision build, enable double usage warning.
-- MPI_INCLUDE_PATH : /usr/local/openmpi-3.0/include
-- MPI_LIBRARIES : /usr/local/openmpi-3.0/lib/libmpi.so
-- MPI_CXX_INCLUDE_PATH : /usr/local/openmpi-3.0/include
-- MPI_CXX_LIBRARIES : /usr/local/openmpi-3.0/lib/libmpi.so
-- 
-- ------------------ YOU HAVE NO X11-LIBS ------------------
-- CCmake found no X11-libs on your system, which are required for the GUI.
--  You CAN add the flag -DGUI=OFF to avoid using X11
CMake Error at CMakeLists.txt:200 (message):
  X11 is required for GUI.

I also checked for the installed X11 libraries in my system:

[root@localhost build]# rpm -qa | grep libX11
libX11-devel-1.6.5-1.el7.x86_64
libX11-common-1.6.5-1.el7.noarch
libX11-1.6.5-1.el7.x86_64

Despite this other GUI programs are running fine. How can I solve this issue?

Solution

CentOS 7 example, building Relion.

# yum install openmpi-devel fftw-devel fltk-devel
# cp /usr/lib64/openmpi/bin/* /usr/bin/

git clone https://github.com/3dem/relion.git
cd relion/
mkdir -p external/fltk/lib      // 'make install' fails if no (empty) lib/ folder
mkdir build
cd build/
cmake ..
make
.
[100%] Built target tiltpair_plot

# make install

Result : Relion-git.040918-1.el7.x86_64.rpm ( 2.0MB ) https://drive.google.com/file/d/1c3loJFCladmqvemHyKu44FxZzdOr-XJN/view?usp=sharing → Provides /usr/local/bin/{45 files}, /usr/local/lib/{ gui_background.xpm, librelion_gui_lib.so, librelion_lib.so }

Download, and install : cd Downloads/ && yum install ./Relion-git.040918-1.el7.x86_64.rpm

$ relion : The Relion GUI opens OK.

# yum provides */libXcursor.so.1,
Etc. etc. to decide the names of your "missing libX**-devel".

X11 files are a lot more than libX11-devel. And some build scripts will reply for any missing parts of X11 without being specific. Please do # yum install libXmu-devel, which will install "the usual required X11 collection".

@Kund I have libXmu-devel libSM-devel libICE-devel installed in my system, still cant proceed with cmake.

[Knud Larsen]

Is cmake still asking for X11-libs ?

[diffracteD]

Yes. Still giving the same error. @Kund

[diffracteD]

I'm not building an XFCE package. I'm building an open source package on XFCE env

[diffracteD]

Relion-2.3 is the package @Knud

[diffracteD]

I performed the exact same steps, yet I'm stuck with the same error !

[Knud Larsen]

Solution : Get the rpm package, and install it with yum. ( No CUDA )

[diffracteD]

Alright but without CUDA its highly time-inefficient to use the package.

[diffracteD]

@Kund I have all the Xlib (you mentioned) present in /usr/lib64, however can't resolve the issue. I don't get it why cmake cant find these !! Is there any way to manually point the libraries to cmake ?

[Knud Larsen]

Did you install all libX[name]-devel ? ... I.e. "so.1" won't do for cmake. Files required for compiling are libX[name].so , found in packages-devel. .... And by the way, no reason to build anything when you can install Relion-git.040918-1.el7.x86_64.rpm

[diffracteD]

@Kund I had installed the rpm but after successful installation when I ran relion it gave me an error: relion: error while loading shared libraries: librelion_lib.so: cannot open shared object file: No such file or directory. That is why I'm trying to build it.

[Knud Larsen]

? May be you lost /usr/local/bin/ from the LD_LIBRARY_PATH ? → See edited answer.

Building on my previous attempt for building from Source > Including X11 header files manually to the ''/usr/include'' moved the installation quite a bit but again stuck at: /usr/include/X11/Xlib.h:1686:1: error: ‘_X_DEPRECATED’ does not name a type _X_DEPRECATED ^ /usr/include/X11/Xlib.h:3571:3: error: expected initializer before ‘_X_SENTINEL’ ) _X_SENTINEL(0);

[diffracteD]

Thank you. Both worked for me. .rpm also worked and simultaneously I have been able to build from the source. Thanks a lot !
