Okay, I installed gcc and cairo-devel.

Thanks! I still run into a problem when I try to compile the C renderer: at

#include <librsvg-2.0/librsvg/rsvg.h>

it complains that the file cannot be found. Indeed there doesn't appear to be any librsvg sub-directory in /usr/include. While the binary run-time library librsvg.so is present in /usr/lib64. I did not run into this problem in my own installation of Rocky Linux.

Is there some additional rsvg package that we are still missing? (Like rsvg-devel?)

[Edit] The include files for gdk-pixbuf-2.0 were similarly missing. I was able to work around it by copying the /usr/include/librsvg-2.0 and /usr/include/gdk-pixbuf-2.0 subtrees from my own installation of Rocky Linux 8 to the folder where I compile (/home/chessvariants/hgm), and adapt the compilation command to look for the include files there. This still led to an error message from the linker, which was not able to find the rsvg-2 run-time library. It appears to be called librsvg-2.so.2 here, and the command probably choked on the final .2. Mentioning the library pathname explicitly, rather than using the -lrsvg-2 compiler flag, solved that problem, and finally gave me a binary. I don't understand how the system here can be so different from the installation I have on my PC.

There still is a problem left. I tried the binary in /index/fen2.cgi, but when I try to invoke it there from the web it just download the binary. So apparently it does not recognize the .cgi extension as special. Then I tried it in /cgi-bin, where I would expect CGI files to work. But it appears that files there are not accessible from the web at all (not even text files like piclist.txt). So it seems the server is somehow configured to block access to the cgi-bin directory. (Even though there are many files there, including PHP and CGI files.)
