现在,我没有在spec文件中看到任何Requires选项,但原始RPM仍然尝试安装一些额外的包.指定这些依赖项的位置？这是在configure脚本中完成的吗？
原始RPM：

所以,我已经安装了自定义版本,repoquery仍然显示speex和其他版本,尽管在yum安装期间不需要它们.这些信息来自哪里？
# repoquery --requires --resolve pjproject speex-0:1.2-0.19.rc1.el7.x86_64 libstdc++-0:4.8.5-16.el7_4.2.x86_64 libgcc-0:4.8.5-16.el7_4.2.x86_64 glibc-0:2.17-196.el7_4.2.i686 libuuid-0:2.23.2-43.el7_4.2.x86_64 gsm-0:1.0.13-11.el7.x86_64 glibc-0:2.17-196.el7.x86_64 libsrtp-0:1.4.4-10.20101004cvs.el7.x86_64 openssl-libs-1:1.0.2k-8.el7.x86_64
RPM为您提供的一个方便/烦人的事情是自动发现提供和需求.有一种记录在
filter its helpfulness的方法.例如,spec文件中的这些行将有效地删除您尝试删除的三个库的直接依赖关系：
# https://fedoraproject.org/wiki/Packaging:AutoProvidesAndRequiresFiltering
%global _privatelibs lib(gsmcodec|srtp|speex)[.]so.*
%global __provides_exclude ^(%{_privatelibs})$
%global __requires_exclude ^(%{_privatelibs})$
$rpm -q –provides -p ../RPMS/x86_64/pjproject-2.3-6.el7.centos.x86_64.rpm
libpj.so.2()(64位)
libpjlib-util.so.2()(64位)
libpjmedia-audiodev.so.2()(64位)
libpjmedia-codec.so.2()(64位)
libpjmedia-videodev.so.2()(64位)
libpjmedia.so.2()(64位)
libpjnath.so.2()(64位)
libpjsip-simple.so.2()(64位)
libpjsip-ua.so.2()(64位)
libpjsip.so.2()(64位)
libpjsua.so.2()(64位)
libpjsua2.so.2()(64位)
pjproject = 2.3-6.el7.centos
pjproject(x86-64)= 2.3-6.el7.centos
但是,如果使用repoquery,则会获得询问上游包repo而不是自己的自定义构建的结果.
