g++ and knoppix

[rafal_rr]

i've tried to install lactivemq-cpp libraries, but i get error:

checking for pthread_create in -lpthread... no configure: error: libpthread not found!

but lpthread.so is in a directory /usr/lib nevermind. i've tried to compile an example program in c++ and i get error:

g++: command not found

how to install g++ using apt-get? there is no "build-essential" (like in ubuntu) in repositories

Try using aptitude. You didn't say which version of knoppix you are using , but in 6.0.2 ,

aptitude update

followed by

apt-cache policy build-essential

will show that it is in indeed available.

aptitude install build-essential

will install it, you will have to reject it's first attemp and accept a downgrade of some other packages before it will install. Then you should be able use aptitude to install the libraries.

Good luck.

Not sure, perhaps posting in one of the Activemq forums would yield an answer.
