Win32 -> PowerPC(32) Linux: "Illegal instruction" 10 years 6 months ago #4494
|
The ToolChain-Builder is great! Very easy to use.
But I run into a problem: Cross Compilation Win32 -> PowerPC(32) Linux: "Illegal instruction" when generated executable is executed on Target Machine. Cross Compilation Win32 -> PowerPC(32) Linux works so far, that an executable is created. But the generated executable is faulty inside: "Illegal instruction" is printed when executed on the target machine. The Dump also looks faulty/incomplete: ELF Header

http://elfio.sourceforge.net/So something did happen to the toolchain ? Or FPC was untested for a while with PowerPCs(32)? The test program was reduced to the simplest form, still "Illegal instruction": program project1;
begin
writeln('Hello together');
end.So the question is: Who has an idea, what can be done to create a valid ELF image ? |
