error whilst compiling EPW-4

[eliephys78]

I am trying to compile EPW-4. Everything runs smoothly and I was very close to to correctly compile both QE-5.4.0 and EPW-4 until the code stops:

IF (iverbosity.eq.1) write (stdout, *) &
1
Error: Expected expression in WRITE statement at (1)
make[1]: *** [setphases.o] Error 1
make[1]: Leaving directory `/home/eamoujaes/espresso-5.4.0/EPW/src'
make: *** [epw] Error 2

How can this be corrected?

thank you

Dear eliephys78,

This is quite interesting. I never had this bug before.
Could you tell me which compiler you are using (exact version) ?
In the meantime I suppose the bug for that compiler could be corrected with:

open the "setphases.f90" and remove line 188

From:

Code: Select all

  IF (iverbosity.eq.1) write (stdout, *) &
!$$  if (.true.) write (stdout, *) & 
     ik0, nset, (ndeg (iset) ,iset=1,nset)

to:

Code: Select all

  IF (iverbosity.eq.1) write (stdout, *) &
     ik0, nset, (ndeg (iset) ,iset=1,nset)

Could you tell me if that works?

Thank you,

Best,

Samuel

Line 188 is the one above the "!" but this cannot be taken out. The line starting with "!" is line 189 and this is already "commented":

188 IF (iverbosity.eq.1) write (stdout, *) &
189 !$$ if (.true.) write (stdout, *) &
190 ik0, nset, (ndeg (iset) ,iset=1,nset)

so which line do I have to remove? My compiler version is:

gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC)

Dear sponce,

thanks for your help. It actually worked.

Dear eliephys78,

Thank you for the information. I've modify the code in the trunk of QE.

I would recommend to update, if possible, your compiler to more recent version (like gcc 4.9.3 or so).

Best,

Dear Developers,
I followed the video in your youtube for installing EPW and everything went well except the last step "make epw" it always gives me the following message

I found the executable file in ../espresso-5.4.0/bin/ but when I tried to run epw by using the command "./epw.x" , gives

Fatal error in PMPI_Comm_rank: Invalid communicator, error stack:
PMPI_Comm_rank(108): MPI_Comm_rank(comm=0x0, rank=0xf00568) failed

Note, I am using gcc 4.8.4 in my machine. I am waiting for your a valuable suggestions. Thank you in advance.

Best regards,
Khaled.

Dear Khaled,

Which mpi implementation are you using?

Could you try the following inside /home/khaled/Espresso_5.4/espresso-5.4.0:

Code: Select all

make distclean
./configure
make pwall
make ph
cd EPW/src
make 

Best,

Samuel
