Golang makes statically linked binaries. (Well, until you use cgo.) By default, Crystal generates dynamically linked binaries. You absolutely do not need Crystal to run them. But you do need: - Boehm GC (libgc-threaded) - libevent - PCRE if the program uses regexps - libyaml if the program uses yaml - OpenSSL if the program uses crypto/TLS (?) Here's an example ldd output: /usr/local/bin/shards: libyaml-0.so.2 => /usr/local/lib/libyaml-0.so.2 (0x8c0bb1e000) libpcre.so.1 => /usr/local/lib/libpcre.so.1 (0x8c0bd3c000) libm.so.5 => /lib/libm.so.5 (0x8c0bfb8000) libgc-threaded.so.1 => /usr/local/lib/libgc-threaded.so.1 (0x8c0c1e6000) libthr.so.3 => /lib/libthr.so.3 (0x8c0c444000) libevent-2.1.so.6 => /usr/local/lib/libevent-2.1.so.6 (0x8c0c66c000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x8c0c8c3000) libc.so.7 => /lib/libc.so.7 (0x8c0cad2000) libdl.so.1 => /usr/lib/libdl.so.1 (0x8c0ce8f000) libcrypto.so.42 => /usr/local/lib/libcrypto.so (0x8c0d091000) You can try `crystal build --static` though :)
