How to compile makeobj?

How does one compile the makeobj sources that come with the svn? I have been following the instructions here successfully when compiling Simutrans itself, but they do not explain how to compile makeobj. Any help would be appreciated.

You need cygwin or mingw. I did not bother with a MSVC script.

Prissi,

thank you for your reply. However, I am having great difficulties compiling with either of the utilities that you suggested. There is no setting in the makefile for cygwin, and using the mingw settings, the output complains of a missing mingw file. I have tried all of the other settings, but all produce missing file errors. Using mingw, I get the following output:

Edit:

This is the output that I get with cygwin:

I should be most grateful for any ****istance.

I can tell that cygwin compiled succesfully but linker can't find mingw32.o or mingw32.a or whatever extension it has. You must find it and add that folder to path, then it might work. Or complain about other not found files... :(

VS,

thank you for your reply. Where might I find those files?

Errrrm, dunno.

But if you have msvc all set up for Simturans, I just now updated the sticky introductory thread (its first post) with project files for Makeobj ;)

VS,

thank you. I downloaded the files (incidentally, it seems that the makeobj files should go in the makeobj subdirectory, not the trunk directory, as all of the relative paths to the trunk directory start with "../"), but, when I go to build makeobj, I get the following linker errors:

Edit: When I opened the file on its own, rather than adding it to the Simutrans project, it seemed to work, except, for some reason, I had to change the order of certain lines of code in dr_rdpng.c (putting png_uint_32 widthpu32,heightpu32; above the pngptr lines, or else it would give me unfathomable syntax errors).

Here I am not so sure I understand what you are saying.

You can build either Simutrans or Makeobj. Not both. -> Two project files

For Makeobj, you need to define MAKEOBJ (most likely cause of this problem) and link with zlib and libpng. The project file should take care of that... If you want to set this yourself, it's somewhere in the menus. I don't remember where - once set, you (or I) can forget about it.

Folder is correct since I have a folder with all project files, thus separated from actual code so that svn does not complain all the time. But anything that has path .. leading to trunk works.
