Build Wine rpm with 32 bit application support

Wine is a software to allow running Windows applications in Linux, MAC etc. platforms. It is available for installation from package managers like yum (RHEL, CentOS) and apt (Ubuntu). You can find more details on how it works in Wine wiki.

But the default Wine package available from package manager does not have support for 32 bit Windows applications. This was the case for me.

There are 2 ways to upgrade your wireshark version from the default version provided by Ubuntu -


Add a third party repository to your repo conf and you can upgrade the wireshark. But I do not prefer this way as it imposes the restriction of version that can be installed.Install wireshark from source. This is best way as you can install any version of wireshark in your Ubuntu.

Here are the steps to follow -
