Hi,
I am trying to have Orbiter running under winex in Linux. I have plenty of experience in programming but I haven't used much debuggers. I would have few questions.
What is the difference between dll load methods "builtin" and "so" when debugging witch one should be used ?
When using "so" mode this error is generated. I added "_ftol" in libmsvcrt.so and that error is no longer generated. Is that right thing to do ?
When using "builtin" mode these errors won't appear. But it will crash the same way.
---------------------------------------------------------------------------------------------------- fixme:win32:ELF_FindExportedFunction function ftol not found: /usr/local/lib/libwine.so: undefined symbol: ftol err:win32:PE_fixup_imports No implementation for MSVCRT.dll.237(_ftol) imported from C:\Orbit_new\Modules\Luna.dll, setting to 0xdeadbeef

What are these ?

from msvcrt.spec: @ forward -noimport _ftol ntdll._ftol @ cdecl ?terminate@@YAXXZ() MSVCRT_terminate
This is the final crash.

I know very little about this. It seems that processor is trying to execute code in 0xdead001e. That would indicate a missing function. If that what it is. What is the missing function ? Where it shoud be ? What is calling it ? What is "1e" in 0xdead001e
I dumped MSACM32.DLL and it does not inport any MSVCRT.DLL functions. acmStreamUnprepareHeader disassembly doesn't show anything weard either.
