Executing the configure script of centericq-4.8.9 ended thus:
“checking for vector… no
configure: error: You need to have the libstdc++ headers installed”
The header vector.h is in /usr/include/g+±3 with a lot of other headers. It would seem that the compiler isn’t looking there. I tried using CPPFLAGS=-I/usr/include/g+±3, but that didn’t make any difference. I suppose I could comment out checks for the headers that are in /usr/include/g+±3, but I’m hoping someone has a more elegant solution.
