Hi to all, I'm trying to build first commit of git made by Linus. I mean the one named e83c5163316f89bfbde7d9ab23... (I think this is enough). But at building stage i have the following error: make all gcc -g -o update-cache update-cache.o read-cache.o -lssl /usr/bin/ld: update-cache.o: undefined reference to symbol 'SHA1_Update@@OPENSSL_1_1_0' //usr/lib/i386-linux-gnu/libcrypto.so.1.1: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status make: *** [update-cache] Errore 1 Makefile:16: set di istruzioni per l'obiettivo "update-cache" non riuscito I run a debian stretch on my machine. Could anyone help me? Thanks in advance. Fabio.
