Can't guess file format: unhandled file extension 'pcd'

[msfTinMar]

Hello,
I just updated Cloudcompare in ubuntu, and now I can't open .pcd files.
The error is get is [Load] Can't guess file format: unhandled file extension 'pcd'
Is that supposed to happen?

best regards

Indeed, the default PCD I/O filter was broken (it worked only for a few kinds of PCD files). It has been replaced by the qPclIO plugin (a new kind of plugin for loading/saving files). So you simply have to compile qPclIO (see CMake) to be able to load PCD files.

I am stuck on this also. Apologies for my ignorance but Daniel could you please details steps needed to make this work a little more please.
Thank you

You shouldn't need to do it now (this was true a long time ago ;). What version are you using?

I'm trying to compile CC on a mac since the lastest OS X does not support the older CC version that had pcd-support.

I can compile everything fine as long as I don't include the QPCL plugin. This is the error message I am getting:

I've set all my paths correctly and my guess would be that it's related to my default compiler. gcc -v gives me:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/c++/4.2.1
Apple LLVM version 8.0.0 (clang-800.0.42.1)
Target: x86_64-apple-darwin16.4.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I installed the latest gcc with brew - would it help if I can point the compiler to that version instead of the default one (and if yes, how do i do that)? Thanks a lot, any feedback is much appreciated!

[daniel]

If I remember well OpenMP is not supported on Mac OS (or maybe it's only with gcc on Mac OS, or something like this).

However the CMakeLists.txt script in 'plugins\qPCL\PclUtils' does enable OpenMP by default. I guess you should simply remove the '-fopenmp' part on line 7 of this script.

Thanks Daniel - that worked and compiled fine now. Installation works too, but I keep getting this libc++abi.dylib error when I try to open CC. Do you have any idea what this is related to?

[daniel]

Not at all (I'm not a Mac user/dev). Have you tried to ask google? ;)

[kcal]

Got it working now, with pcd support! For future reference, removing qt5 from homebrew and installing qt5.6.2 through the qt creator package did the trick.

[Matt]

Does this issue have a workable resolution? I've encountered this error and I'm not sure how to fix it.

For reference, I'm using CloudCompare v2.8.1 binaries on Ubuntu 14.04.
