Hello
I am trying to install coz on CentOS and have tried to closely follow all the installation instructions. However, I am getting following errors:

I have installed the libelfin as per the directions and have set the PKG_CONFIG_PATH. Can you please let me know what steps I am missing?
gettid errors are likely #154
As for not finding your headers, try setting CPLUS_INCLUDE_PATH to the root of your libelfin's include dir, it sounds like you installed it to a non-standard location.
Agreed on the diagnosis. How old is this version of CentOS? (I just am wondering whether this is really worth supporting at this point.)
I get these errors on CentOS Linux release 7.7.1908 (Core)
According to Wikipedia, full updates for version 7 have already ended (though maintenance releases continue). Can you test on the latest release? (Version 8)
I can't but I'm sure it would work; Cent8 has a much more modern toolchain. From my understanding, CentOS is more common in enterprise than consumer/regular user land, so it's really up to you how you weigh supporting it. We were able to work around this issue by manually reverting #154.
I was having this issue when attempting to build on CentOS 7.9.2009. My solution was simply to clone the libelfin project inside of the /libcoz folder and build it there; the file structure looking something like this: coz/libcoz/libelfin/dwarf/....
I had a lot of weird issues on CentOS 7 that I had to correct (like LD_LIBRARY_PATH not pointing to /usr/lib), but I was able to build everything successfully.
