[pcl_io] 'boost::filesystem::filesystem_error' what(): boost::filesystem::status: Function not implemented: "XXXX.pcd"

[gaolingminhhh]

I have tried many times to reinstall boost(boost version is 1.76.0) and pcl(1.12.0) ,but the error still here .
When I type pcd_viewer at ubuntu shell,the error occured.

terminate called after throwing an instance of 'boost::filesystem::filesystem_error' what(): boost::filesystem::status: Function not implemented: "kf_output.pcd"

But I have wrote a small program to test boost like this

#define BOOST_NO_CXX11_SCOPED_ENUMS  
#include <boost/filesystem.hpp>  
#undef BOOST_NO_CXX11_SCOPED_ENUMS  
#include <iostream>  
int main(int argc,char** argv)  
{  
    if (boost::filesystem::exists("1.pcd"))  
    {  
        std::cout<<"file exists "<<std::endl;  
    }  
    else  
    {  
        std::cout<<"file not exist!!!!!!!!!"<<std::endl;  
    }  
    return 0;  
}

the output
file not exist!!!!!!!!!

• OS: [Ubuntu 18.04]
• Compiler: [GCC 7.5.0]
• PCL Version [1.12.0]
  -Boost Version[1.76.0]

So you just write pcd_viewer and then the path and name of your .pcd file? Are you sure path and name are correct and the file really exists?
Can you run the same command, but with valgrind in front of it?
I am not sure what you intend to do with the program you wrote. You are checking the existence of a file with name "1.pcd", in the same directory as the program. How does that help?
Is it possible that there are non-ASCII characters in the path or name of the file? I don't know how well Boost handles those.

I solved the problem with uninstall boost1.76 and installed boost 1.65.But I don't know the why.

I wrote the program to sure the boost work rightly,I have tracked the pcl::io::loadpcdfile,always corrupted at boost::filesystem::exists().But the small program never corrupt.

But you only check "1.pcd" in the small program? Have you checked with the filename you pass to the pcd_viewer? Something like boost::filesystem::exists(argv[1]) and then give the filename on the command line, just like you do with the pcd_viewer?
As I said in my last comment, my best guess would be that there are non-ASCII characters in the path or name of the file, which Boost might not handle correctly.

Closing this issue, since it appears to be solved and since the problem seems to come from Boost, not PCL
