ERROR: couldn't parse MOT configuration

In my CentOS machine (CentOS 7.8.2003 (Core), gcc 4.9.4) launching:

$>pfaedle -D -x [osmfile] -i [feedname]

I get this error:

/usr/local/etc/pfaedle/pfaedle.cfg:8, at pos 25: Expected <valid regular expression>, found <regex error: '\[': regex_error>

So I compiled the same (current) source code on a MacBook (OS Catalina 10.15.5, clang 11.0.3): launching pfaedle with the arguments everything work fine.

A past issue was closed in 2019; should I try with gcc > 4.9.4 on CentOS?

[patrickbr]

Yes, a newer gcc version will most likely fix this issue :) Although it should work in 4.9.4, according to the research I did back in 2019. Are you absolutely sure you are compiling with gcc 4.9.4?

[marti1959it]

Yes 4.9.4; I'll try a > 4.9.4 tomorrow

Now it works fine on CentOS! I installed gcc 9.1.0 but got the same run error. By default the 9.1.0 (compiled from source) executable is installed in /usr/local/bin, but pfaedle build script seems to search gcc in /usr/libexec folder, where is installed gcc 4.8.5 (guess by CentOS 7 default...). So I uninstalled 4.8.5: the pfaedle compilation process was now OK (it found 9.1.0), but in runtime it crashed:

pfaedle: /lib64/libstdc++.so.6: version 'GLIBCXX_3.4.20' not found (required by pfaedle)
pfaedle: /lib64/libstdc++.so.6: version 'GLIBCXX_3.4.26' not found (required by pfaedle)
pfaedle: /lib64/libstdc++.so.6: version 'GLIBCXX_3.4.21' not found (required by pfaedle)

This issue was resolved by setting the environment variable LD_LIBRARY_PATH to:

export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/usr/local/lib64:/usr/lib64

At last pfaedle works fine! Guess it works fine in 4.9.4 as I you told me...I'll keep 9.1.0 anyway... Thank you @patrickbr !
