The above line means:
gcc -c "compile only, don't link"
ins "use ins as input"
ins.o "use ins.o as input"

I suppose you ought to do one of the following:

gcc -c -o ins.o ins.c
compile ins.c, don't link, output to ins.o

gcc -o ins ins.o
link the compiler output ins.o, output to executable ins

gcc -o ins ins.c
compile and link ins.c, output to executable ins

A C program source should have a name ending in .c (for a program) or
.h (for a header). So the tules for tri.o and ins.o are upside-down: I
would expect tri and ins to be executables, not sources.

See
man gcc
