Porting S2 to qnx700

[BeyondWang]

Hi Guys,
We team want to use S2 on QNX700, after a quick start through cross-compile, lots of error occurs.
I do not get any description of QNX. Is it feasible to port it to QNX? Any pages we can refer to?

It should be feasible to port. Only C++11 is required. Do you have abseil-cpp working and the tests passing? What are your errors?

I'm not sure what it takes to get cmake to work with a cross-compiler. Is it finding the QNX include/lib dirs?

Hi,

It reports "#error "Unsupported bytesex: Either IS_BIG_ENDIAN or IS_LITTLE_ENDIAN must be defined"", after I add "add_definitions(-DIS_LITTLE_ENDIAN)" in the toolchain file, it build successfully. I will test if all the functions work as expected.

Thanks a lot.

You probably want to add defined(__QNX__) (or whatever the appropriate macro is) here:

s2geometry/src/s2/base/port.h

Line 151 in 7f0dc0b

// IS_LITTLE_ENDIAN, IS_BIG_ENDIAN

Yes, that's where the error message locates.
