Current github makeobj generation fails

[Junna]

Ehm, I'm having trouble compiling the latest version of the pak from github; it fails on the LMR 4-wheel coaches, saying that certain images are missing. Am I doing something wrong or is it some mistake in the .dats?

[jamespetts]

Hmm - that's rather odd, as mine works. Are you sure that you have the up to date version? What is the specific error that you are getting?

Says "empty image" doesn't exist.

I doubt my makeobj is entirely up to date however, as I was unable to compile it myself from source (missing some library and I couldn't find out which exactly and where to get it.) Could you provide a new compile?

Upon trying to compile latest makeobj I get the following errors I am unsure how to resolve, but assume is related to something missing:

[VS]

_png_* ones are from libpng (library)
dr_* are from simsys16.cc or some equivalent (ours)

The rest... I'm not sure right now. Check logs for added files, that should be at least some of these. Some of the errors also vaguely feel like linking with outdated object file or some such.

Hello

Makeobj: This is not the latest version but it works.

Are you compiling on Linux or Windows? Which compiler are you using?

Are you compiling on Linux or Windows? Which compiler are you using?

Windows and MSVC++2010. I believe I am lacking some libraries or so - I could find no list of requirements, and I am not sure my libpng is up to date, as I could find no precompiled lib/include to use of the latest version.

I added the ottd-auxillary libraries and (I think) it was bzlib already.

Have you tried to compare your own MSVC++ project with my MSVC++ project on Github to see what you are missing?
