Compiler generated files bug?
(1/1)
BlueHazzard:
I want to use protobuf and use advanced compiler options for this.
I use
--- Code: ---protoc -I$file_dir --cpp_out=proto $file
--- End code ---
for the compiler command. So all source files will be created in the "proto" sub folder of the project
and i use this for the autogenerated files:
--- Code: ---proto/$file_name.pb.cc
proto/$file_name.pb.h
--- End code ---
But this does not work.
It searches the file in the base path of the project. So ignores the "proto" part of the directory....
i looked into the code and this is quite specious:
--- Code: --- wxFileName tmp
...
tmp.SetFullName(tool->generatedFiles[i]);
wxString tmps = tmp.GetFullPath();
// any macro replacements here, should also be done in
// CompilerCommandGenerator::GenerateCommandLine !!!
tmps.Replace(_T("$file_basename"), pf->file.GetName()); // old way - remove later
tmps.Replace(_T("$file_name"), pf->file.GetName());
tmps.Replace(_T("$file_dir"), pf->file.GetPath());
tmps.Replace(_T("$file_ext"), pf->file.GetExt());
tmps.Replace(_T("$file"), pf->file.GetFullName());
Manager::Get()->GetMacrosManager()->ReplaceMacros(tmps);
ProjectFile* pfile = AddFile(targetIndex, UnixFilename(tmps));
--- End code ---
is it a good idea to give wxFileName a string that cans contain "$" charachters? Why not replace the path before passing it to a wxFileName object?
oBFusCATed:
Does it work if you do the replacements before the c-tor of wxfilename?
BlueHazzard:
The problem is this line:
--- Code: ---tmp.SetFullName(tool->generatedFiles[i]);
--- End code ---
it sets only the name of the file, but if you use a path in the generated files this won't work...
My actual solution:
--- Code: ---wxString tmps = tmp.GetPath(wxPATH_GET_VOLUME | wxPATH_GET_SEPARATOR) + tool->generatedFiles[i];
--- End code ---
i don't know the full logic about all this, but i think this is the better solution instead of the current one...
oBFusCATed:
The logic is that the file is expected to be created in the same directory as the original file.
If you want to create it in a relative path then you need to use a path join operation.
The proposed code could probably work, you should check if setfullname doesn't do anything fancy...
I am not sure if some normalization shouldn't be done after the join. Unfortunately all wxFileName functions are rather expensive, so they should be avoided as much as possible.
Can you open a ticket on sf.net and provide a sample project which is miscompiled with the current version?
