(I realize that this is not a well-documented question, but as I write below I don't know which information to share; I am willing to provide more as it appears useful)
I am modifying a pre-existent collection of Fortran90 programs for data processing in fluid-dynamics (which was not written by me), not substantially but more on the structural side (e.g. using shared files instead of copies and making it independent of its location).
When compiling, I get the following error (compiling on MacOS 10.15.2 with mpifort->gfortran), which I can not relate to anything since I don't know Assembly language:
gfortran -c -mcmodel=medium -fconvert=big-endian -ffixed-line-length-140 -fno-align-commons -fbounds-check -Wall -cpp -O3 -I/usr/local/include/ -L/usr/local/lib/ -lfftw3 -lm -Wl,-stack_size,0x10000000,-stack_addr,0xc0000000 calc_pressure.f90
/var/folders/l7/2v2vqp1n1xlcp_6_gg2y7k0r0000gn/T//ccz3q6Vo.s:1537:2: error: unsupported symbol modifier in relocation
movabsq $270012416+_stermc.4115@GOTOFF, %rdx
^
I can compile in a way that I don't get this error, but it doesn't happen changing this file: I just reference different directories (i.e. different simulations).
I cannot share the whole code, both because it would be too much and because it is not open; but I am willing to provide more details, as long as I can.
The code below gives a similar error: Undefined symbols for architecture x86_64: "_GLOBAL_OFFSET_TABLE_"
program main
integer i
double precision, dimension(10) :: myarr
double precision :: q
q = stuff(i)
contains
function stuff(j) result(y)
integer :: j
double precision, dimension(10) :: ar
do j=1,10
ar(j) = 1.0d2 * j
end do
write(*,*) ar
end function
end program
