[Mesa-users] Filename expansion causing line truncation compiler warnings/errors

[Warrick Ball]

Hi everyone,

I'm pretty sure this issue has been solved before but I can't seem to find 
it in the MESA Users' archive.  I've installed MESA on a cluster where the 
users are issue folders with fairly long paths.  When these are expanded 
in some of the MESA macros (usually `mesa_error(__FILE__,__LINE__)`), the 
line then exceeds the accepted line length and errors abound.  For 
example, I've currently got an astero work folder where I get

$ ./mk
gfortran -Wno-uninitialized -fno-range-check -fmax-errors=12  -fprotect-parens -fno-sign-zero -fbacktrace -ggdb -finit-real=snan -fopenmp -fbounds-check -Wuninitialized -Warray-bounds  -I/rds/projects/2017/ballwh-stellar-modelling/mesa/10398/include -c -ffree-form -x f95-cpp-input -I/rds/projects/2017/ballwh-stellar-modelling/mesa/10398/star/astero/defaults /rds/projects/2017/ballwh-stellar-modelling/mesa/10398/star/astero/src/astero_data.f
/rds/projects/2017/ballwh-stellar-modelling/mesa/10398/star/astero/src/astero_data.f:851:132:

              if (ierr /= 0) call mesa_error(__FILE__,__LINE__)
                                                                                                                                     1
Error: Line truncated at (1) [-Werror=line-truncation]
/rds/projects/2017/ballwh-stellar-modelling/mesa/10398/star/astero/src/astero_data.f:851:43:

              if (ierr /= 0) call mesa_error(__FILE__,__LINE__)
                                            1
Error: Missing ')' in statement at or before (1)
...

and then a bunch more of the same.  (These issues are a bit strange 
because it doesn't *look* like the line is too long but it is once 
__FILE__ and __LINE__ are expanded.)

Which is the relevant flag to change in the makefile, and to what? 
Unfortunately, just relocating to a shorter path isn't particularly easy.

Cheers,
Warrick
