[ECOS] Re: heapgen.cpp: C++ compiler not installed on this system

[Vinay R Patil <post2vinay at gmail dot com>]

hi John,

Yes, the toolchain I download was configured for C only.
I tried rebuilding the Tool chain according to link you have given,

1. The web page was updated in 2004, most of packages mentioned in
link were not available for download, and OpenCore is moved to SVN.
2. I modified to the Tool chain build script to configure GCC build,
by adding --enabled-languages=c,c++. Then I got below error,
   It looks the looks GCC code avialble at SVN of OpenCore doenst
configured for C++ at all.

I am now stuck, looking how to proceed further,
