Hello Alexander, from my understanding, we need to build a GO 32 bits DLL for a C software.
To load this DLL, the C software loads an entry point function called _RVExtension@12 wich is a decorated/mangle C name/ It seems that cgo doesn't accept to export functions with '@' in name composition wich is accepted by convention in C Le lundi 24 juin 2019 10:42:07 UTC+2, Alexander Kapshuk a écrit : > > If I understand it correctly, cgo should have generated a > _cgo_export.h header with a declaration for your exported function. > Can you please post the generated declaration? > > On Mon, Jun 24, 2019 at 12:47 AM <ono...@gmail.com <javascript:>> wrote: > > > > We are trying to make the x32 version of the extension, as shown in the > link below. > > https://community.bistudio.com/wiki/Extensions#C.2FC.2B.2B > > > > How we see, for x64 we must use entry points > > > > RVExtension > > RVExtensionArgs > > RVExtensionVersion > > > > > > but for x32 > > > > _RVExtension@12 > > _RVExtensionArgs@20 > > _RVExtensionVersion@8 > > > > > > It is very hard for me to explain to you exactly what we need, because I > am new to this language, and C doesn’t know at all.
