Help / Re: High CPU usage during build operation when verbose is enabled

« Last post by stahta01 on Yesterday at 07:00:38 pm »

I would suggest disabling all the CB plugins you are not using or try selecting a different default compiler to see if any difference happens.
Edit: Also, change the project compiler and see if that helps.

Some regex implementations are known to perform badly. For details see e.g:

Help / Re: High CPU usage during build operation when verbose is enabled

I believe that there are a lot of codes to parse the compiler log message. So, if the compiler generate a lot of warnings, it takes a lot of time to parse those output.

So, sometimes, the building stage is really slow.

Not sure how to improve.

If I remember correctly, I have added some checks for the return line encoding, see this: The encoding text from GCC compiler should be UTF8 by default?

Help / High CPU usage during build operation when verbose is enabled

« Last post by christo on Yesterday at 12:57:04 pm »

Seeing high CPU usage by codeblocks, more than that of gcc, during compilation. I'm working external makefile project (makefile generated by cmake), and lot of verbose is enabled.

When analysed by perf, pcre2_match_32 is taking most of the CPU. Cause is that each of the build log line is check against 34 regular expressions.

I'm not much familiar with regex, but can anything to be done to improve the performance here?

As far as I know, there is currently no tool to convert virtual folders into real folders on the system.

Thank you.

I just compiled it on ubuntu linux without any compile-error. Arch I can do only in the evening. Since the configure args are the same and both use wxWidgets trunk, chances are, that the outcome will be the same on arch.
