1. get all the -Fu and -Fi folders so the package can search them and allow the user to include/exclude them from profiling, which method to use in LazIDEIntf?

Again a couple of questions regarding the IDE interface;
</div>
<div>
</div>
<div>
1. Is it possible to (temporarily) suppress the check if a file on disk has changed?

With a simple patch the central loading can be extended for an overload. This costs no performance and has very low maintenance cost for the FPC team, so there is a good chance the patch will be applied. At that time DoDi was working on the compiler, so I waited for the dust to settle and then I forgot to provide the patch. The patch is on another computer. I can search for it next week.</div></div></blockquote><div>Sounds very promising, I would welcome your sources to see if I can use this in fpprofiler.</div><br><blockquote type="cite"><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">A custom compiler can then add the file hook to feed fpc with preprocessed source files, for example your fpfprofile code.</div></div></blockquote><div>Or even read the files from a stream instead, so the profiling code can be inserted on the fly?</div><br><blockquote type="cite"><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Of course eventually it would be nice if FPC could use an optional preprocessor without the need to compile your own compiler.</div></div></blockquote><div>I'm for that, sure. But I would also like to be able to use a profiler without the need to have to compile a new compiler with different pre-processor. Quite some users might find this difficult or even scary.</div><br><blockquote type="cite"><div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Another solution is to implement a ramdisk.

Not my prefference, in that case I would rather stay with disabling the check in Lazarus for changed files.</div><div><br></div><div><br><blockquote type="cite"><div>

2. I would like to add a unit search path to the project and later be able to remove it again. Is this possible?
