Install git-email on RHEL 7.0

The RHEL 7.0 ISO doesn’t provide git-email rpm package by default. Because the git rpm provided by ISO file isgit-1.8.3.1-4.el7.x86_64.rpm, you should download the same version here, and install it:

[root@linux ~]# rpm -ivh git-email-1.8.3.1-4.el7.noarch.rpm
warning: git-email-1.8.3.1-4.el7.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
error: Failed dependencies:
        perl(Authen::SASL) is needed by git-email-1.8.3.1-4.el7.noarch
        perl(Net::SMTP::SSL) is needed by git-email-1.8.3.1-4.el7.noarch

From the error message, we know also need to use yum to install perl-Net-SMTP-SSL and perl-Authen-SASL packages:

[root@linux ~]#yum install perl-Net-SMTP-SSL
[root@linux ~]#yum install perl-Authen-SASL

Done!

 

Install ktap on RHEL

My RHEL is 7.0, the minimal installation. Build ktap, it outputs the following error:

[root@redhat ktap-master]# make
    CHK libelf
Makefile:108: No libelf found, disables symbol resolving, please install elfutils-libelf-devel/libelf-dev
make -C /lib/modules/3.10.0-123.el7.x86_64/build M=/root/ktap-master modules
make: *** /lib/modules/3.10.0-123.el7.x86_64/build: No such file or directory.  Stop.
make: *** [mod] Error 2

(1)

To fix “No libelf found, disables ...” error, you need to install elfutils-libelf-devel package:

[root@redhat ktap-master]# yum install elfutils-libelf-devel

To fix “*** /lib/modules/3.10.0-123.el7.x86_64/build: No such file or directory.” error, you need to install kernel-devel package:

[root@redhat ktap-master]# yum install kernel-devel

Then make is OK!
