How can I make rpm tell what libraries are provided inside it?

Dear stackoverflow users,

I was trying to install newer openssl in CentOS 6.5 as follows:

# curl -O https://www.openssl.org/source/openssl-1.0.1i.tar.gz
# tar xzf openssl-1.0.1i.tar.gz
# sed -i "s@/usr/lib@/usr/lib64@g" openssl-1.0.1i/openssl.spec
# tar czf openssl-1.0.1i.tar.gz openssl-1.0.1i
# rpmbuild -tb openssl-1.0.1i.tar.gz

However installing the generated rpm returns following errors:

bash-4.1# rpm -Uvh /rpmbuild/RPMS/x86_64/openssl-1.0.1i-1.x86_64.rpm

error: Failed dependencies:

Thus I modified openssl.spec as follows:

# diff -u .openssl/openssl.spec openssl-1.0.1i/openssl.spec

Inside the created package libssl.so.10 and libcrypto.so.10 do exist:

# rpm -iqlp /rpmbuild/RPMS/x86_64/openssl-1.0.1i-1.x86_64.rpm | grep \.10
/usr/lib64/libcrypto.so.10
/usr/lib64/libssl.so.10

But it is not recognized as libraries to be provided:

Summary     : Secure Sockets Layer and cryptography libraries and tools
Description :
The OpenSSL Project is a collaborative effort to develop a robust,
commercial-grade, fully featured, and Open Source toolkit implementing the
Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1)
protocols as well as a full-strength general purpose cryptography library.
The project is managed by a worldwide community of volunteers that use the
Internet to communicate, plan, and develop the OpenSSL tookit and its related
documentation.

OpenSSL is based on the excellent SSLeay library developed from Eric A.
Young and Tim J. Hudson.  The OpenSSL toolkit is licensed under an
Apache-style licence, which basically means that you are free to get and
use it for commercial and non-commercial purposes.

This package contains the base OpenSSL cryptography and SSL/TLS
libraries and tools.
SSL  
config(openssl) = 1.0.1i-1
libcrypto.so.1.0.0()(64bit)  
libssl.so.1.0.0()(64bit)  
openssl = 1.0.1i-1
openssl(x86-64) = 1.0.1i-1

modifying LIBCOMPATVERSIONS= to LIBCOMPATVERSIONS=10 in Makefile* does not solve this issue. So the question is, “How can I make rpm tell it has libssl.so.10 and libcrypto.so.10?”

Any comments would be appreciated, thank you.

Solution

You could use the ‘’Provides: ‘’ tag:

[embed]Manual Dependencies You might have noticed that we've been using the words "requires" and "provides" to describe the dependency…ftp.rpm.org
