Hi… :-)

When installing rams, it seems to be a problem with the glic libraries. Here is the prompt:

How can i solve this?

Hi waldyd,

The warning messages are just saying that the dynamic libc library must be use for some of the symbols and your application will not be completly static. Since libc must be on every Linux system, I doubt this will cause problems.

For the undefined references, you want to find the library which contains the symbols. In this case, the symbols can be found in “/usr/lib/gcc/i386-redhat-linux/4.0.0/libgcc_eh.a”. Using the “nm” utility, followed by a “grep” will show if the symbol is present and an upper case “T” indicates that the symbol is defined. A “U” indicates that the symbol is used but undefined. For exmple:

fedora4:/usr/lib/gcc/i386-redhat-linux/4.0.0% nm libgcc_eh.a | grep -i "_Unwind_GetCFA"
nm: unwind-sjlj.o: no symbols
00000224 T _Unwind_GetCFA

To search multiple libraries use the “foreach” command.

foreach i ( `ls *.a` )
foreach? echo $i
foreach? nm $i | grep "_Unwind_GetCFA"
foreach? end

Exactly why the g++ exception handling library is needed, I’m not entirely sure, but adding “-lgcc_eh” should solve your linking problem.

Hope this helps,
Mat
