cannot find crt1.o:

[meocomandante]

I'm compiling a program based on f77 and I get that

/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
collect2: ld returned 1 exit status

crt1.o and crt0.o both are in

/usr/mipsel-linux-gnu/lib/crt1.o
/usr/lib/x86_64-linux-gnu/crt1.o

even after add path to bashrc

Library_PATH=/usr/lib/x86_64-linux-gnu:$LIBRARY_PATH
export LIBRARY_PATH

I'm getting crazy with this error.
Does anyone have a solution to this problem?

my system is lubuntu 18.04.05

You may just need to install the gcc for mutlilib support

sudo apt install gcc-multilib
