[Q-e-developers] Compilation problems with xx.f90

[Martin Schlipf]

Dear Paolo and Nicolas,

the fixes in exx.f90 are still not good enough to work for gfortran. The 
following lines are still too long and break our buildbot in Oxford
1001, 1856, 1897, 2889, 2898
In addition the lines 2563 and 2565 are too long after the preprocessor 
replaces the _CX and _CY with the macros defined in the beginning of the 
file.

Regarding the MPI_IGATHERV command: This is not a routine of the 
compiler, but of the MPI library. Which MPI library are you using?

Cheers,
Martin

First I had a stupid (but never seen before) issue with lines being truncated, in particular when the compiler-time modification of the lines was used, e.g.
