Using make.inc.serial got error msg: ‘syscall’ was not declared in this scope

Hello All, I did not see this error show up in earlier issues, does any one have a suggestion? I tried compiling on an Ubuntu system.

src/count-tri.cpp: In function ‘int main(int, char_)’: src/count-tri.cpp:76:66: error: ‘syscall’ was not declared in this scope printf("My TID: %ld running on CPU: %d\n", syscall(SYS_gettid), sched_getcpu()); make[1]: _* [src/count-tri.o] Error 1 make[1]: Leaving directory `/home/saguinag/Software/INDDGO/util'

I have encountered the same problem when trying to follow the instructions in ./INSTALL (using make.inc.serial, SuiteSparse and metis):

$ make

After commenting line 76, util/src/count-tri.cpp compiled without problems.
