no such file or directory

[Ak493812]

Yesterday my code was capable of opening a file "larger.dat" and today I get this message when I am debugging:

std::string::c_str (this=0xffbffaf0)

at /home/maciej/src/opencsw/pkg/gcc4/trunk/work/solaris10-sparc/build-isa-sparcv8plus/objdir/sparc-sun-solaris2.10/libstdc++-v3/include/bits/basic_string.h:1820

who is majiej? I'm not sure why it is not searching for the file in my own directory.

The message is innocuous. It means the debugger can't find the sources referenced by the debugging symbols in the library. maciej is the user name in their computer of the person who built the library.

[Ak493812]

but is program actually able to open the file that i input?

and is there any way to fix it so it properly compiles?

I guess? Can't you tell from the program's behavior?

and is there any way to fix it so it properly compiles?

The message doesn't imply an improper compilation.
