CAMB_sources: compiling issues with gfortran

[Ze Fonseca]

Hi

I have been trying to compile CAMB_sources with gfortran. I'm using gfortran 4.4 in the server. Without further changes from the original final except in the makefile I get several errors in compiling equations.f90. I tried the following FFLAGS:
FFLAGS = -O2
FFLAGS = -O3 -fopenmp -ffast-math -funroll-loops
FFLAGS = -Ofast -march=native -fopenmp

All give me the same errors and warnings. I copy some examples:

equations.f90:1711.132:

og10Ndm)*((-4.D0*W%wing2(j)/chi*adotoa-2.D0*(-W%dwing2(j)*chi-W%wing2(j))/c
1
Error: Expected a right parenthesis in expression at (1)
equations.f90:1711.132:

og10Ndm)*((-4.D0*W%wing2(j)/chi*adotoa-2.D0*(-W%dwing2(j)*chi-W%wing2(j))/c
1
Warning: Line truncated at (1)
equations.f90:1712.24:

k*sigma+2.D0*W%wing2(j)*etak/chi/k/EV%Kf(1))
1
Error: Unclassifiable statement at (1)

Using the previous version of CAMB_sources I am able to run the code. Any hints on whats going on?

Looks like the compiler is truncating lines, try compiler options like
-ffree-line-length-132

(or you may need gfortran 4.7+)

I got the following error for the command line:

error: unrecognized command line option "-ffree-line-length−132"

I'll try to upgrade the compiler.
