Before cautiously tackling a shared library, I thought I'd have a trial
run with cmem in the program that's going to call it. I find that if I
put 'cmem, heaptrc' at the start of the .lpr it runs and I get heaptrc
output, /but/ one of the files has a wildly erroneous error number.
Should read "wildly erroneous line number".
If I remove both cmem and heaptrc from the .lpr I still get the error,
despite having carefully removed all binaries etc. Is there a cache
somewhere that also needs to be cleared?
AFAIK cmem and heaptrc only change the program and not any other unit
ppu/o.
But you can use Run / Clean up build files to make sure.
I did do, and checked for old files in the project directories. I'm
definitely running the right binary, since I don't get heaptrc output if
I disable it in the IDE options. I get the error whether or not I'm
using cmem. Laz 1.1, FPC 2.6.0, Linux, GTK2, all CG range checks etc.
enabled.
How do you share the shared units between library and program?
I haven't got that far yet, I'm trying to tackle it one stage at a time.
But my plan is to use a class which wraps and opens the shared library
on first use, that contains methods which are exact analogues of
exported entry points (and can be described by a .inc file shared
between the two projects).
