This is the dumbest thing. The makefile couldn't be simpler: $ cat makefile hello: hello.c gcc -o hello hello.c
When I run this, I get: $ make gcc -o hello hello.c make: *** [hello] Error 255 If I do a dry run and pass the output to the shell it works just fine: $ make -n > dryrun $ sh dryrun (no errors) I tried changing the line terminators in the makefile from CR/LF to LF. The SHELL environment variable points to a valid sh. "which sh" finds the same shell. I tried the --unix and --win32 switches. The output of make -d ends with: Must remake target `hello'. gcc -o hello hello.c Putting child 0x1002c7f0 (hello) PID 444 on the chain. Live child 0x1002c7f0 (hello) PID 444 Got a SIGCHLD; 1 unreaped children. Reaping losing child 0x1002c7f0 PID 444 make: *** [hello] Error 255 Removing child 0x1002c7f0 PID 444 from chain.
