Dear All,
gcc-11.2.0 fails to compile src/pmemd/src/cuda/gpu.cpp line 2852
with "error: ordered comparison of pointer with integer zero".
That line 2852 also look suspicious:
if (nmrat[i][0] >= 0 && nmrat[i][1] >= 0 && nmrat[i][2] >= 0 && nmrat[3] >= 0) {
"nmrat" is a two-dimensional array. And all other accesses to the
variable in that file are two-dimensions.
Should "nmrat[3]" therefore instead be "nmrat[i][3]"??
If "nmrat[3]" is as expected the comparison operator is not
standard compliant and should be rewritten.
Best regards
Thomas Zeiser
