rpc/rpc.h missing - building dovecot for RHEL 8.1

Latest response

I am attempting to build the dovecot package from the source code provided for RHEL 8.1. All of the dependencies have been met for the build. While compiling I get the following error. I have queried yum to see what provided /usr/include/rpc/rpc.h and it didn't return any package. From my google searches other seem to have similar issues.

Does anyone know what RHEL package has rpc/rpc.h?

Hi Mikel,

Unfortunately I cannot provide you with a solution which lets you safely install /usr/include/rpc/rpc.h on RHEL 8.
The file was included in the glibc-headers package on RHEL 7 - but it's not included in that package on RHEL 8.

RHEL 7.7 :

sudo rpm -ql glibc-headers | grep rpc/

RHEL 8.1 :

sudo rpm -ql glibc-headers | grep rpc/

As manipulating glibc and related headers may lead to a broken and unusable system, I recommend to open a case.
Eventually Red Hat has an alternative solution, or can provide you with a safe workaround ... I wish you good luck ! :)


I am guessing you have the rpcgen package installed, because, if I am reading the code right, that is what triggers the build requirement for rpc/rpc.h which I don't believe RHEL 8 has. You could try uninstalling the rpcgen package before building dovecot, or could wait for RHEL 8.2 which (based on the beta) should have a later version of dovecot that handles this situation better.

It looks like rpc.h is now provided by libtirpc-devel:

$ rpm -qlp libtirpc-devel-1.1.4-3.el8.x86_64.rpm | grep rpc.h
