[CP2K-user] << first time compiling CP2K with toolchain >>

[I. Camps]

Hello,

I am completely new to CP2K. 

In order to compile it, I am following the instruction to use toolchain.

My system is Ubuntu 21.04, 64 bits, Intel compilers, MPI and MKL. Also has 
GPU 1050Ti.

The command I am using is:

*./install_cp2k_toolchain.sh -j 4 --gpu-ver=P100*

which is returning me an error when compiling FFTW:

*ERROR: (./scripts/stage3/install_fftw.sh, line 58) Non-zero exit code 
detected.*

Looking for make.log, I found: 


















*tensor.c(31): error: identifier "__INT_MAX__" is undefined       if 
(FINITE_RNK(rnk) && rnk > 1)           ^tensor.c(67): error: identifier 
"__INT_MAX__" is undefined       if (!FINITE_RNK(sz->rnk))            
^tensor.c(79): error: identifier "__INT_MAX__" is undefined       if 
(FINITE_RNK(t->rnk)) {           ^tensor.c(108): error: identifier 
"__INT_MAX__" is undefined       if (FINITE_RNK(x->rnk)) {           
^compilation aborted for tensor.c (code 2)make[2]: *** [Makefile:463: 
tensor.lo] Error 1*

Searching the web, I found that this error is related to use Intel to 
compile FFTW: link 
<https://community.intel.com/t5/Intel-C-Compiler/icc-and-fftw-and-INT-MAX/m-p/1221838#M37735>
.

But I don't know how to implement this.

Also, I installed CP2K from the Ubuntu repos, but I am getting this error:

*cp2k: symbol lookup error: cp2k: undefined symbol: 
__elpa_MOD_elpa_allocate*

I have installed the ELPA libraries (also from repos).

Any help is welcome!
