CB perf
grahamo:
Hi,
I have to say I'm delighted with the setup... Codeblocks compiles our 30 .a's/.so's and links our exe perfectly. It runs perfectly under the debugger. Its compilation time is *five* times faster than the monolithic make system.
I've configured codeblocks to use dependencies and I've set the "Number of processes for parallel builds" to 8 (the number of CPU's on our linux server host where I compile). Our linux host is not loaded with other users.
Now I'm delighted with the setup and people are going to be delighted with the performance. However seeing as I'm a newbie I might as well ask...
Is there any other way to speed up my build. I might naively expect codeblocks to compile 8 times faster than the monolithic make, seeing as its configured to run on 8 cpus versus the old monothreaded makefile approach.
Am I dreaming? Or is there another area I should look at to bleed another bit of performance out of CB. FYI html logging is disabled and running from the compile line has been tested. It gives me a tiny perf improvement but I'm looking for tips from the pro's here: )
Again, nice job. Its been a while since I've used an IDE that runs as smoothly (and I've used just about all of them over the years! :)

Fastest way is to use batch build mode with all plugins (except compiler, of course) disabled. Leave the rest as you did.

I have searched a lot for this, but I can't find where you configure it?

Which part of the logical or ("|") you need, depends on the version of C::B you use.
By the way:
recent versions of make have the "-j" switch to set the number of parallel processes.

Thanks! I am using version 8055, and there is no "Compiler and debugger" setting. There is one for the compiler and one for the debugger, but neither includes this option. I suppose this has been moved elsewhere?
