cd was just change directory to the root of the repo so that the Cmakelists.txt file is accessible on the path.

You can get CMake from here: https://cmake.org/download/
Make sure CMake is also on the Path then run CMake . in the Collada2glTF directory to build out the solution file - Collada2GLTF.sln.

To open the sln file get Visual Studio Community Edition here: https://www.visualstudio.com/vs/community/

Build the solution file in Visual Studio (CTRL+SHIFT+B). This will give you collada2gltf.exe command line tool in the bin\debug or bin\release subfolder depending on your build configuration (I believe default is debug).

(cd stands for "change directory", and is what you usually type to change between directories at the Command Prompt...)

BTW: You also need a Visual Studio installed for all this.

Regarding CMake: You can use it from the command line as well. For us windows users, using "cmake-gui" may be more convenient, though:

Start "cmake-gui"
In the field "Where is the source code", enter the directory where you cloned the repo. For example, C:/COLLADA2GLTF
In the field "Where to build the binaries", enter a target directory. I'd recommend to use a different directory than the source directory, to keep the source directory clean. For example, C:/COLLADA2GLTF.build
Press "Configure". This will ask for the compiler. Select your visual studio compiler there. It may print some warnings in the output, but you can ignore them for now.
Press "Generate". This will create the build files in the output directory that you defined.
Open ALL_BUILD.vcxproj with visual studio.
Press F7 to compile
If there are no errors, then the resulting exe file will be in C:\COLLADA2GLTF.build\bin\Debug\

EDIT: I was too slow here.

Compiling on Windows w/o libpng is simple:

Clone repository

git clone --recursive https://github.com/KhronosGroup/COLLADA2GLTF.git

Create VS solution

cd COLLADA2GLTF
cmake .

Open COLLADA2GLTF.sln
Build collada2gltf project

from collada2gltf.

javagl commented on May 24, 2024

There's a pending pull request with build instructions for Linux ( #6 ). Further build instructions (for Windows, where the handling of dependencies may be a bit more fiddly) will probably be added soon. Depending on whether you explicitly want to build it on your own or just use a precompiled binary, you might want to have a look at #1 (comment)

@lexaknyazev Thank you for the tips,
But can you please explain a bit more?
--what does cd stand for? (in cd COLLADA2GLTF)
--cmake?

@javagl @sbtron Thank you guys; I will try these steps. Hope it works

I ran into following error while building the .sln.

javagl commented on May 24, 2024

I cannot check of verify this right now, but a first guess based on the message: In the toolbar of Visual Studio, there are two dropdown menus: The left one allows selecting "Debug", "Release" etc. The right one by default shows "x86" (or "Win32", this depends on VS version and other things). You may have to select an entry that indicates 64 bits, usually called "x86_64" or "x64"

(If there is no such entry, you will have to create one - a quick websearch brings up http://www.viva64.com/en/l/0004/ which shows the basic steps, if necessary)

@javagl Thank you for the suggestion. I tried the x64 config. Probably that wasn't the issue.

I'm assuming the original error on Win32 config exists due to unlinked libraries. Still looking into it.

from collada2gltf.

javagl commented on May 24, 2024

Yes, exactly: My guess was that the "unresolved external symbol: png...." messages had been caused by the fact that it could not link the PNG library due to the wrong architecture type, which it said as the last message. And the messages "module machine type 'x64' conflicts with target machine type 'X86'" still indicate that there is something wrong with this setting. But you most likely already found the related stackoverflow posts (http://stackoverflow.com/questions/3563756/fatal-error-lnk1112-module-machine-type-x64-conflicts-with-target-machine-typ , which says indicates that you might have to manually select "Properties > Configuration Properties > Linker > Advanced > Target Machine: MachineX64", or http://stackoverflow.com/questions/25936688/lnk1112-module-machine-type-x64-conflicts-with-target-machine-type-x86 ...). But actually, the files as generated by CMake should be "clean" in that sense, and it should not be necessary to manually fiddle around with these settings. Since I can't reproduce the error at the moment, I can't give further or more focussed hints right now (sorry).

The unofficial build provided here #1 worked.
I ended up using ubuntu bash now available in windows 10.

@javagl Thank you again for your input.

javagl commented on May 24, 2024

Just the quick link for the main developers:

COLLADA2GLTF/COLLADA2GLTFWriter.cpp

Line 238 in 6bc66f2

 this->_asset->log("WARNING: unsupported opaque mode:%s fallback to A_ONE\n", opaqueModeToString(opaqueMode).c_str()); 

Transparency and opacity in COLLADA is .... sometimes not entirely straightforward, and there are some related issues already.

Do you have the option to change the transparency/opaqueness mode in the COLLADA input file?

A_ZERO and A_ONE should conceptually be supported. (Whether they are properly translated into glTF is a different story, though....)

Closing as this seems to have been resolved, feel free to reopen if you have any other issues.
