Problem with the linking about libccd HOT 13 OPEN

I have the same problem. You can try to add extern int ccdGJKIntersect(const void *obj1, const void *obj2, const ccd_t *ccd) before main() function. And if you find red line under CCD_INIT,you can try this https://github.com/danfis/libccd/pull/40/files

from libccd.

I had similar linking issues. I had set the library to be built static in cmake but it seemed like the CCD_EXPORT definition wasn't right. Is the CCD_STATIC_DEFINE defined properly? Anyway, I was able to resolve the issue by overriding the ccd_export.h with

#ifndef CCD_EXPORT_H
#define CCD_EXPORT_H

#define CCD_EXPORT

#endif

from libccd.

Have same problem - fatal error LNK1120.
I tried to do as advised vekkuli, but it did not help.

Warning means you can run it but you still have some potential problem. In most situation, it is just a useless hint. It depends on your compiler.

But I still get the error LNK1120.
I tried different tips, but nothing helps.

Please tell me your compiler, if you use visual stdio2015, maybe I could give you my test program.

This is a test program for cube, open libccdtest.sln, maybe it works.

Where? I do not see the link.

At first， I used the link as I said in the comment.But then I found that it is more convenient to put some files directly into the project.I couldn't find the original version.Sorry.😐

No problems, thx.

I found sulution:
Add "#define CCD_STATIC_DEFINE" to "config.h" and copy to includes.
It's work for me.

from libccd.

I've solved linkage errors with msvc like this.
If static, CCD_STATIC_DEFINE has to be defined:

• At libccd compilation time (otherwise it leads to a lot of C4273 warnings "inconsistent dll linkage", and after that it may fail to link into an executable or shared lib).
• When consuming static libccd.

CMakeLists.txt of libccd could be easily fixed by defining CCD_STATIC_DEFINE not only when CCD_HIDE_ALL_SYMBOLS is ON, but also when BUILD_SHARED_LIBS is OFF.
