Installing package increases lazarus.exe size
lazarus / 13-General

----------------------------------------------------------------------

I downloaded lazarus-1.0.8-fpc-2.6.2win32.exe and installed Lazarus.

I then installed the TOpenGLcontext component and pressed "Save and
rebuild".

This installed the component but now lazarus.exe is about 168 MB but
used to be about 14 MB.

I saw some tips about reducing exe size for user programs.

Do these settings also need to be used when rebuilding Lazarus itself?

168 MB is too low space for the actual pc, i think this is
unnecessary.

Regards.

QuoteDo these settings also need to be used when rebuilding Lazarus
itself.Yes (Lazarus is just another LCL application, you can say it's
built on top of itself similar like FPC is built with itself)

Using FPC 2.6.2:
On 64-bit Linux I get 79 MB for a debug IDE. A 32-bit version would be
smaller.
This is still less than half of your 168 MB.

Optimized IDE is 22 MB here. It opens substantially faster than the
debug version (naturally).

Curious - do you see any improvement if using -Xs? Using -g- should
not generatede debug info in the first place - does the strip step
remove more info?
(If so, I might adjust my own build tools  )

Well, look for yourself: http://photobase.co/photo/e9e3a2ama8.jpg

This is on WinXP SP3 32bit, standard Lazarus 1.0.8.

Nice picture, bit useless without comparison though - but your answer
is yes, I suppose....

Probably the already-compiled-with-debuginfo ones. For the people that
want to get deeper into this, that's what MAP files are for.

Thanks. exe size is now about 17MB with some more packages installed.

When I selected Optimized IDE the options -O2 -g- -Xs were
automatically set.
