The gcc version error

[Gogo-scc]

I had updated GCC to 4.9,But error

If the error appears - this means that the compiler you used has a regex implementation which is faulty. Please check newer gcc. Maybe you should use at least 5.0? I have not tested such old compiler, I would generally prefer something newer - or just use docker images for compilation.

Centos 7 --> gcc v7.3 Centos 8 --> gcc v8.5 Centos 9 --> gcc v11.3 I suggest you build on a newer version of your OS. Back in the day, I rember you could build gcc from source and upgrade to a newer version without upgrading the OS, but, I'm not sure you have a good reason to do this.

Thanks @luss for good suggestion. I want to add that setting up custom complicated environments it not a good idea. If you find an error I would not have patience and time to recreate the same environment in my lab to help you. Please use docker images instead. The docker image contains all commands to compile both on Debian and CentOS so you are able to extract them and even compile the code manually if needed.

Definitely agree w Adam. Adam has worked very hard for several years to make OLR be a well tested solution for the mission critical task it does.

Thanks @luss - in fact it does not make really sense to spend tens of hours to allow the code to be build with all possible compiler versions. This is waste of time. To be sure that actually all different compiler versions work I would need to repeat all test cases with all possible compiler versions. I would rather spent time on real work. We have Docker these days and you can just copy the compiled binary to any system. @Gogo-scc, in the future you can of course imagine to add support also some other OS-es like Solaris or AIX. If there is reasonable business justification of course. Today I really don't have such boxes so I can't phisically even check if the code compiles.
