Link /usr/lib64/libssl.so and /usr/lib64/libcrypto.so to cargo build ?

[tjyang]

Hi
c2rust is a good tool for newbie like me. After playing around with the examples. I am trying bigger one like sqlite3 and smaller one like nrpe.

• Manually merged check_nrpe.c and utils.c into check_nrpe1.c
• check_nrpe1.c are able to be compile via following command but need to link to ssl and crypto libs.

gcc -g -O2 -I/usr/include/krb5  -DHAVE_CONFIG_H -I . -o check_nrpe1 ./check_nrpe1.c -lssl -lcrypto

• gen_c2rust_check_nrpe.sh and build c2rust from github.

[me@rocky8t01d src]$ cat gen_c2rust_check_nrpe.sh
c2rust transpile -b  check_nrpe1 -e  compile_commands.check_nrpe.json -o c2rust_check_nrpe
[me@rocky8t01d src]$ c2rust -V
C2Rust unknown (5ce9db6f6 2022-12-16) dirty 1 modification
[me@rocky8t01d src]$

• cargo build errors below have many C function calls not found due to C libssl.so not linked.

[me@rocky8t01d src]$ grep SSL_CTX_free /usr/include/openssl/*
/usr/include/openssl/ssl.h:void SSL_CTX_free(SSL_CTX *);
