Hallo Leute,
habe ein Problem beim laufen einer Application wenn sie ohne "dynamic RTL" gebuildet wurde. Hoffe, die englische Beschreibung stoert nicht - wenn doch, werd kann ichs gerne nochmal in deutsch tippseln 
I have a BCB6 project which runs fine in the debug environment / on the development pc (WinXP).
But what I want is to compile a standalone .exe which runs on its own without any additional files (components, dll, ..).
For this, as I understand, the following options in the project settings have to be untagged:
- Packages - Build with runtime packages
- Linker - Use dynamic RTL
As soon as I untag the "use dynamic RTL" the following error message shows up when I run the program:
"Access violation at address xxxxxxx. Read of address 00000000."
By debugging into the project, I could gather the following informtation:
This happens BEFORE the main fuction is called. (placing breakpoint at beginning of main, looking at callStack).
When debugging, the execution stopps in ../cbuilder6/include/stl/_ios.c at the basic_ios template, which is not my code.
The callStack lists Log::Log, which is in my code (code and callstack see below).
It is possible to place a breakpoint in the line marked with "#1" but will not reach "#2" - the problem happens before.
I have already tried to remove global variables from class files (found this to be the possible cause by research).
This did not change anything.
There are, however, files with global functions in the project.
I am new to BCB and would very much appreciate your help.
