[vbox-dev] Patch for x86_64 build and a question

[Larry Finger]

I know that building VBox in x86_64 isn't supported, but I have gotten most of the way. So far, the 
only change I have needed was the following patch to configure.

My question concerns setting the proper path for libstdc++. My build goes fine up to building the 
tests, where I get the following:

kmk[4]: Entering directory `/home/finger/vbox/src/VBox/VMM/testcase'

collect2: ld returned 1 exit status

Which version of libstdc++ does the build need? Mine is /usr/lib64/libstdc++.so.6.0.8.

Any suggestions on what I need to change?

Thanks,

Larry
