Device::SerialPort on Redhat 8

The end of life for Redhat 6.2 security updates happened at the end of March. Because of this, I have been upgrading our remote buildings with Redhat 8. Since each building has a T1 router, I wrote a small program to log the routers messages to a text file. While performing these upgrades, I ran into some small trouble with my code, which relies on the perl module: "Device::SerialPort". While attempting to install this, I ran into this error:

[root@domain Device-SerialPort-0.13]# perl Makefile.PL
Finding ioctl methods ...
trying 'termios.ph'... nope
trying 'asm/termios.ph'... nope
trying 'sys/termiox.ph'... nope
trying 'sys/termios.ph'... nope
trying 'sys/ttycom.ph'... nope
trying 'sys/modem.ph'... nope
Device::Serial could not find ioctl definitions!
Perl did not find any .ph files to get at least the following ioctls:
        TIOCMBIS
        TIOCMBIC
        TIOCMGET
        CRTSCTS
Please check your Perl installation, or read 'man h2ph'.  As root, you may
need to run:
        cd /usr/include; h2ph -r -l .
before the Perl *.ph files will work.
 

So, I did what it told me to do: 'cd /usr/include; h2ph -r -l .' However, after trying to build Device::SerialPort again, it gave the same error. Time to google.

I came across a post: (Long url moved to end of page ) Which started me in the right direction. Although this post didn't fix *my* problem, at least I was headed in the right direction. After a trial and error with the post, this method finally worked for me:

cd /usr/include/
h2ph asm/*.h
h2ph -r -l termios.h
h2ph -r -l asm/termios.h
h2ph -r -l sys/termios.h
h2ph -r -l sys/ttychars.h
h2ph asm/termbits.h
h2ph asm/ioctls.h
h2ph asm/termios.h
 

I had setup a machine last weekend using this, and I am currently configuring another machine for this weekend. Good thing for .bash_history, because I had no idea on which combination of using 'h2ph' worked for me.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
