MinGW symbols not found

[ddobrev]

While wrapping QtCore, no symbol is found. The searched for symbols (that is, the parameter "symbol" of Library.FindSymbol) have a format similar to:

??0QForeachContainerBase@@qeaa@XZ

while the keys of Library.Symbols are of the formats:

__imp___Zls6QDebugRK21QPersistentModelIndex
_z_inflatePrime

Changing Driver.Options.Abi to Itanium (the default is Microsoft) makes no difference.

Hey Dimitar,

What controls the mangling of the is the MicrosoftMode option. This seems a bit unexpected, I'll fix it to use the ABI option in the future.

You can see in Parser::SetupHeader.

    TargetABI = Opts->MicrosoftMode ? TargetCXXABI::Microsoft
        : TargetCXXABI::GenericItanium;

Unfortunatey, setting Driver.Options.MicrosoftMode to false produces tons of header parsing errors.

You are right, these two concepts (name mangling/ABI and Microsoft parsing extensions) should be decoupled from each other to handle cases like MinGW code correctly. I will send a fix soon.

Could you clarify this? I don't want name mangling at all. I tried to set the LanguageVersion to C and that just crashes everything with warnings about using the GNU standard C library with "C++ objects"

Based on what you said I cannot tell what the issue might be or it is related to this issue.

Please open a new issue and provide more information so that we can help.

@tritao Done, thanks for your time.
