You only need to install i686 packages plus libgcc.i686 that seem not to be
picked up automatically (otherwise ld would complain "cannot find -lgcc_s").
After that I can build a 32-bit application that uses OpenSSL library:
$ cat test.c
#include <stdio.h>
#include <openssl/crypto.h>
int main(void) {
printf("%s\n", SSLeay_version(SSLEAY_VERSION));
return 0;
}
$ gcc -m32 test.c -lcrypto
$ file a.out
a.out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically
linked (uses shared libs), for GNU/Linux 2.6.18, not stripped
$ ldd a.out
linux-gate.so.1 => (0x00ede000)
libcrypto.so.10 => /usr/lib/libcrypto.so.10 (0x00396000)
libc.so.6 => /lib/libc.so.6 (0x00cc5000)
libdl.so.2 => /lib/libdl.so.2 (0x00fc1000)
libz.so.1 => /lib/libz.so.1 (0x006fd000)
/lib/ld-linux.so.2 (0x00711000)
$ ./a.out

For you reference, this is a complete list of i686 packages I installed into my
RHEL 6.10 x86_64 system:
# rpm -qa |grep i686
