I am probably missing something obvious - after downloading Pavel's github tree for cifs-utils to see if it worked around a setcifsacl problem, and running configure, make didn't build setcifsacl and building it explicitly got this error (this is Ubuntu 18). Does anyone remember the missing dependency or other build configuration step that would cause this error: ~/cifs-utils-staging# make setcifsacl gcc -Wall -Wextra -D_FORTIFY_SOURCE=2 -fpie -pie -Wl,-z,relro,-z,now -g -O2 -o setcifsacl /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start': (.text+0x20): undefined reference to `main' collect2: error: ld returned 1 exit status Makefile:778: recipe for target 'setcifsacl' failed make: *** [setcifsacl] Error 1 -- Thanks, Steve
