Re: [rvm-research] Resolving External References

Hi,

I am now just experimenting with a simple function system call "int
k_poc_sys_call"
I have added relevant declarations in :

./rvm/src/org/jikesrvm/runtime/SysCall.java

./rvm/src/org/jikesrvm/runtime/BootRecord.java

./rvm/src/org/jikesrvm/tools/header_gen/GenerateInterfaceDeclarations.java

./tools/bootloader/sys.h

./tools/bootImageRunner/sys.C


And I am still getting the error of : [exec]
/home/kmahmou1/jikes/jikesrvm/target/FullAdaptiveMarkSweep_x86_64-linux/libjvm.so:
undefined reference to `k_poc_sys_call'

This function simply returns 0. There is no reference to any external
library.
