I have Ubuntu 14.04. It came with openssl 1.0.1f. I want to install another openssl version (1.0.2) and I want to compile it by myself.
I configure it as follows:
LDFLAGS='-Wl,--export-dynamic -L/home/myhome/programs/openssl/i/lib
-L/home/myhome/programs/zlib/i/lib'
CPPFLAGS='-I/home/myhome/programs/openssl/i/include
-I/home/myhome/programs/zlib/i/include'
./config --prefix=/home/myhome/programs/openssl/i \
zlib-dynamic shared --with-zlib-lib=/home/myhome/programs/zlib/i/lib \
--with-zlib-include=/home/myhome/programs/zlib/i/include
make
make install
After install, when i check the binary with ldd openssl
, and the result is:
...
libssl.so.1.0.0 => /home/myhome/programs/openssl/i/lib/libssl.so.1.0.0 (0x00007f91138c0000)
libcrypto.so.1.0.0 => /home/myhome/programs/openssl/i/lib/libcrypto.so.1.0.0 (0x00007f9113479000)
...
which looks fine. But when I check ldd libssl.so
, the result is:
...
libcrypto.so.1.0.0 => /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007fac70930000)
...
It still uses the system version of libcrypto. I tried different ways to
build, but result is always stays the same.
My question is how to configure the build in a way, that it can hardcode all binary and library dependencies of shared libraries without using LD_LIBRARY_PATH
, or anything like that.

OpenSSL supports RPATH
's out of the box for BSD targets (but not others). From Configure:
# Unlike other OSes (like Solaris, Linux, Tru64, IRIX) BSD run-time
# linkers (tested OpenBSD, NetBSD and FreeBSD) "demand" RPATH set on
# .so objects. Apparently application RPATH is not global and does
# not apply to .so linked with other .so. Problem manifests itself
# when libssl.so fails to load libcrypto.so. One can argue that we
# should engrave this into Makefile.shared rules or into BSD-* config
# lines above. Meanwhile let's try to be cautious and pass -rpath to
# linker only when --prefix is not /usr.
if ($target =~ /^BSD\-/)
{
$shared_ldflag.=" -Wl,-rpath,\$(LIBRPATH)" if ($prefix !~ m|^/usr[/]*$|);
}
The easiest way to do it for OpenSSL 1.0.2 appears to be add it as a CFLAG
:
./config -Wl,-rpath=/usr/local/ssl/lib
The next easiest way to do it for OpenSSL 1.0.2 appears to be add a Configure line and hard code the rpath
. For example, I am working on Debian x86_64. So I opened the file Configure
in an editor, copied linux-x86_64
, named it linux-x86_64-rpath
, and made the following change to add the -rpath
option:
"linux-x86_64-rpath", "gcc:-m64 -DL_ENDIAN -O3 -Wall -Wl,-rpath=/usr/local/ssl/lib::
-D_REENTRANT::-Wl,-rpath=/usr/local/ssl/lib -ldl:SIXTY_FOUR_BIT_LONG RC4_CHUNK DES_INT DES_UNROLL:
${x86_64_asm}:elf:dlfcn:linux-shared:-fPIC:-m64:.so.\$(SHLIB_MAJOR).\$(SHLIB_MINOR):::64",
Above, fields 2 and 6 were changed. They correspond to $cflag
and $ldflag
in OpenSSL's builds system.
Then, Configure with the new configuration:
$ ./Configure linux-x86_64-rpath shared no-ssl2 no-ssl3 no-comp \
--openssldir=/usr/local/ssl enable-ec_nistp_64_gcc_128
Finally, after make
, verify the settings stuck:
$ readelf -d ./libssl.so | grep -i rpath
0x000000000000000f (RPATH) Library rpath: [/usr/local/ssl/lib]
$ readelf -d ./libcrypto.so | grep -i rpath
0x000000000000000f (RPATH) Library rpath: [/usr/local/ssl/lib]
$ readelf -d ./apps/openssl | grep -i rpath
0x000000000000000f (RPATH) Library rpath: [/usr/local/ssl/lib]
Once you perform make install
, then ldd
will produce expected results:
$ ldd /usr/local/ssl/lib/libssl.so
linux-vdso.so.1 => (0x00007ffceff6c000)
libcrypto.so.1.0.0 => /usr/local/ssl/lib/libcrypto.so.1.0.0 (0x00007ff5eff96000)
...
$ ldd /usr/local/ssl/bin/openssl
linux-vdso.so.1 => (0x00007ffc30d3a000)
libssl.so.1.0.0 => /usr/local/ssl/lib/libssl.so.1.0.0 (0x00007f9e8372e000)
libcrypto.so.1.0.0 => /usr/local/ssl/lib/libcrypto.so.1.0.0 (0x00007f9e832c0000)
...
