Hi, We are using gcc 3.4.5-p5 compiler for cross compiling. The host is linux machine. The target is MPC8568 or MPC860 based Powerpc architecture platforms. Target OS is Vxworks. If I enable the optimization flag, -Os (optimize for space), I get some linker errors during final linker check for All the binary images generated. The linker check script checks for any unresolved symbols. The error is because Some symbols are used in the object but not defined and available in any of the binaries. These are Internal local label related symbols? This is a c++ source file. objdump -t Alarm.obj | grep .LC 00000000 *UND* 00000000 .LC1531 00000000 *UND* 00000000 .LC1533 00000000 *UND* 00000000 .LC1536 00000000 *UND* 00000000 .LC1535 00000000 *UND* 00000000 .LC1534 00000000 *UND* 00000000 .LC1532 If I don't use the optimization flag, or use -O1 or -O3, there are no errors. How do I avoid these extra symbols being generated? What are these symbols. Unfortunately I am not able to get a reduced file that results in these errors, and I cannot share the source file as it is proprietary. Thanks, R. Sairam
