linux, datasocket, shared library, error 1143

[gonzaloz]

Hi,

I have the following problem: I've built under linux a shared library using Application Builder of Labview 8.6, this shared library contains function using datasocket, and finally I've linked this library to a C++ program. Sometimes (let say 1 every 10) running my program I get errror 1143 every time I call functions of the library using datasocket, at this point killing my program and running again most of the times works but sometimes not. Am I missing some initialization? or  something wrong with datasocket, or compiler options?

I am using gcc 3.3 and if it could be useful this is what returns ldd on my program (libmylibrary.so is the shared library built with Application Builder):

$ ldd myprogram 

        linux-gate.so.1 =>  (0xffffe000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb75a2000)
        libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xb758a000)
        libmylibrary.so => ./lib/libmylibrary.so (0xb7585000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7579000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7438000)
        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0xb737e000)
        liblvrtdark.so.8.6 => /usr/local/lib/liblvrtdark.so.8.6 (0xb689d000)
        libnsl.so.1 => /lib/tls/i686/cmov/libnsl.so.1 (0xb6886000)
        libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb685f000)
        /lib/ld-linux.so.2 (0xb7f12000)

Thanks in advance,

Hi Gonzalo,

have you installed NI Datasocket?

Yes, in fact, as I said, most of the times it works.

But some times it happens that just killing my program and relaunching it, without changing anything, gives error 1143.

Maybe a problem of firewall?
