G++ Always Fails with Undefined Reference to _Unwind_Getipinfo

G++ always fails with undefined reference to _Unwind_GetIPInfo

GCC-4.6 was finding an older, incompatible version of libgcc.a in $LIBRARY_PATH; in my case it was the also the first entry in $LIBRARY_PATH. The entry was $G95/g95-install/lib/gcc-lib/i686-unknown-linux-gnu/4.0.3/ and relates to the G95 Fortran compiler. I had done this myself some time ago, in the .bash_profile, as I would, at that time, often link C++ programs to the libfortran.a library in that same directory. Removing this entry fixed my problem. In future I would use the -L switch to GCC for such situations.

_Unwind_GetIPInfo' symbol

Looks like you used different stdc libs for compilation and runtime, check G++ always fails with undefined reference to _Unwind_GetIPInfo

How do I output the value to terminal

You could always use printf...

printf("%c", buffer[0]);

Running 'gcc' on C++ source file on Linux gives cc1plus: out of memory allocating ... error message

It turns out I had saved the C++ source file as a UTF-16 Unicode-encoded file, complete with leading Unicode Byte Order Mark (BOM) bytes at the beginning of the file. The file was saved as UTF-16 on a Windows system, committed to a version control system, then checked out to Linux. gcc does support Unicode encoded as UTF-8, but not Unicode encoded as UTF-16.

The solution was to convert the source file back to a standard, non-Unicode encoding.

I got stuck with my first code in C programing language, I cannot make an excutable file?

From the output of the various commands in your other question, it looks like you are using a file system that does not respect or store file permissions (is this an NTFS partition used by Windows and you configured the machine for dual boot?).

Try working in a directory that is on a native Linux file system, for example your home directory.

Looks like LTS doesn't mean they support newer code. I had to upgrade.
