Can't get sample code in readme.md to work

[dsobiera]

I am new to bgfx and am trying the D bindings for it. I am just trying to get the sample app given in the readme.md for the bindings to run to verify a good install. I am running bgfx on Ubuntu Linux.

I am using the instructions from https://github.com/GoaLitiuM/bindbc-bgfx/blob/master/readme.md

I added the subconfigurations in my dub.json because I am trying to do static linking

"subConfigurations": { "bindbc-bgfx": "static" }

"libs": { "bgfxRelease", "bxRelease", "bimgRelease" }

I added the lflag so it could find the .a files :

"lflags": [
    "-L/home/user1/src/d/helloBgfx/bgfx/bgfx/.build/linux64_gcc/bin"
],

and the source code (as supplied by the readme):

---

import bindbc.bgfx;

// commented out because trying to do static link // loadBgfx(); // required with dynamically linked bgfx

bgfx_init_t init; bgfx_init_ctor(&init);

bgfx_init(&init); bgfx_reset(1280, 720, BGFX_RESET_NONE, init.resolution.format);

bgfx_shutdown();

// commented out because trying to do static link // unloadBgfx(); // optional, only with dynamically linked bgfx

---

When I try to do a dub, I get (on linking)...

Performing "debug" build using dmd for x86_64. bindbc-bgfx 0.4.0+108: target for configuration "static" is up to date. bindbc-loader 0.3.1: target for configuration "noBC" is up to date. hellobgfx ~master: building configuration "application"...

and loads and loads of undefineds

Any idea what might be going wrong?

[dsobiera]

I got past those references (and some others) by having my lflags as:

---

"lflags": [
    "-L/home/dsobiera/src/d/helloBgfx/bgfx/bgfx/.build/linux64_gcc/bin",
    "-lstdc++",
    "-lGL",
    "-lX11"
],

---

Now I am getting:

/home/user1/src/d/helloBgfx/bgfx/bgfx/.build/projects/gmake-linux/../../../../bimg/src/image.cpp:5117: undefined reference to `bx::HashCrc32::add(void const*, int)'

as my last reference to try to fix

I got the linking to work

Here is my relevant pieces of my dub.json:

---

"lflags": [
    "-L/home/user1/src/d/helloBgfx/bgfx/bgfx/.build/linux64_gcc/bin"
],
"subConfigurations": {
    "bindbc-bgfx": "static"
},
"libs": [
    "bgfxRelease",
    "bxRelease",
    "bimgRelease",
    "stdc++",
    "GL",
    "X11"
],

Closing the issue as user error fixed but documented for anyone else in this situation.

Thank you, I've updated the readme with additional libraries to be linked against when using static libraries.
