32-bit and 64-bit DLLs?

Open IainNZ opened this issue 10 years ago • 6 comments

I was working on the getting the Julia language binding to LIBSVM working on Windows, and was wondering if you could add a 32-bit and 64-bit version of libsvm.dll to your makefile and repository? I think the current file is 32-bit only.

To keep the package small, we don't want to have both 32 and 64 bit dll in the package at this moment. Later on we may switch to provide only 64-bit dll Could you try to generate it by yourself? See instructions in README. Let us know if you face difficulties. Thanks.

The instructions look good, I'm sure they'd work. The main benefits of you compiling them and including them in the repository is to make it easier for other users (not myself) who don't have the technical skills or confidence to compile libraries, and to provide a centralized source of the binaries that multiple bindings could use. The DLL that is checked in (32-bit version I presume?) is only 160kb, so wouldn't be too space consuming.

Yes, I know. But for libsvm we somehow take code complexity (including number of files) into serious account. Some users may even ask what the difference between these two DLL files is. Adding any file has advantages/disadvantages. We only add things if we have seen enough requests.

I am working on spectra data reduction with LIBSVM working under 64-bit LabVIEW (Window 8.1). 32-bit version of libsvm.dll worked fine with Window 7, but with 64-bit LabVIEW I need 64-bit version of libsvm.llb. I was wondering if you could help me to get the 64-bit version of libsvm.llb.

I've been able to extract and use a 64-bit version of libsvm.dll from Unofficial Windows Binaries for Python Extension Packages.

I am also requesting 64 bit dll. it is extremely weak and funny argument that you cant put 64 bit dll into the package. you can name it libsvm_x64.dll very easy
