[compile error] "posix_fallocate not available on OpenBSD"

[thyssentishman]

Describe the error

I'm trying to port PCL to OpenBSD and I'm running into the following error when compiling:

I believe that posix_fallocate is not yet (or will not be) available on OpenBSD. I bluntly tried to use the __APPLE__ workaround, but I had no success. Any other workarounds I could implement to fix this?

To Reproduce Try building PCL on OpenBSD.

Your Environment (please complete the following information):

• OS: OpenBSD 7.4-current
• Compiler: Clang 16.0.6
• PCL Version: 1.14.0
• PCL Type: Compiled from source

Interesting, on FreeBSD it seems to be available, based on what I have read. Have you tried pretending to be an ANDROID ? https://github.com/PointCloudLibrary/pcl/blob/master/io/include/pcl/io/low_level_io.h#L174 :smile:

Sadly it doesn't work either:

I will have a look

I bluntly tried to use the __APPLE__ workaround, but I had no success

What happened? Another compiler error?

@thyssentishman Can you test if https://github.com/PointCloudLibrary/pcl/pull/5957 solves your problem?

[thyssentishman]

@thyssentishman Can you test if #5957 solves your probl

Yes, it does! And with that pcl finishes to compile. I have the port ready for submission now. Thank you very much.
