AddSize
I'm having a problem that is really working on my nerves for almost the whole day. I'm trying to use AddSize in a section together with a variable or a constant. So what I'm trying to do is something like this:
AddSize $R0
This is situated in a section and $R0 has an integer as value. If I replace $R0 with a value like 24352636, there's no problem.
So the problem is that AddSize doesn't seem to take variables as a parameter. Does somebody have a solution to this problem? thnx
AddSize is a copmile time command, so it can't use variables which only have values on runtime. To change the size of a section on runtime grab the latest CVS version and use SectionSetSize and SectionGetSize.
SetSectionSize 0 100 not working...
Doesn't seem to work like AddSize does?....
Quick answer: No, it doesn't. The documentation is pretty clear on the difference between AddSize and SectionSetSize.
Here is an example.
Section "Foo" GOOBAH
SectionEnd
Section "Bar"
SectionEnd
Function .onInit
SectionSetSize 0 100
SectionSetSize ${GOOBAH} 100
SectionSetSize 1 50
SectionSetSize 2 17
FunctionEnd
The first two SectionSetSize commands do the same thing because 0 is the index of the first section, and ${GOOBAH} refers to that same section. The third SectionSetSize command affects the "Bar" section because 1 is the index of the second section. The final SectionSetSize fails and sets the error flag because there isn't a third section, which the index of 2 refers to.AddSize tells the installer that the current section needs an additional "size_kb" kilobytes of disk space.The difference with SectionSetSize is that it declares an absolute size. The installer will automatically estimate how much space a section will require. You can use SectionSetSize to overwrite this estimate. SectionSetSize does not add to the estimate the installer makes.
