[fpc-devel] Crosscompiling win towards darwin

[Alfred]

Well.

All files that are needed by the linker, have to be found by the linker.
The osxcrosstools use a findfile process that is a bit peculiar. And not 
fully understood by me. Perhaps you can help.

c++ code.

findFile(path):
Options::FileInfo Options::findFile(const std::string &path) const
calls:
if ( findFile(path, {".tbd"}, result) )
		return result;

findFile(path,{...},result):
bool Options::findFile(const std::string &path, const 
std::vector<std::string> &tbdExtensions, FileInfo& result) const
calls
for ( const auto &ext : tbdExtensions ) {
auto newPath = replace_extension(path, ext);
bool found = tbdInfo.checkFileExists(*this, newPath.c_str());
}


So, as far as I understand correctly, if a fpc abc.o file is presented 
towards the linker, it replaces the extension with tbd and goes looking 
for abc.tbd.
I checked: if I add a dummy abc.tbd in the same location, all goes well.

That why I patched the search-process. But this very rude patch only 
took care of .o files.
I forgot about the .or files.

Trying new patches at the moment to no avail unfortunately.
