I have access to computer in a public library and I want to try out some C++ and maybe other code. Problem is that there is no g++ installed and I can't install it using packages because I have no root access. Is there a "smart" way to make a full environment for programming in a home folder?
I have gcc installed (I can compile C code). Also, I have a home folder that is consistent. I don't know where to find precompiled g++, I found only source but I don't know what to do with it. I tried to ask them to install this but it didn't work :)

If you have no gcc there, you need to find a pre-compiled binary of gcc/g++ and install it somewhere. If you have no header files there, you need to find copies of those and put them on the system. There is no 'standard' way of installing gcc in your home folder though.
No. A C-compiler (any C-compiler, GCC is just an example, it might just as well be clang/lvm, or something else) is just incredibly handy to have.
You can run the configure script with the --prefix parameter: ../gcc-4.5.0/configure --prefix=/home/foo/bar. Since it is very likely that the c++ standard library is different then the one on your system, you have to set export LD_LIBRARY_PATH=/home/foo/bar/lib before you can start a program compiled by this compiler.

If you want to install it as a local user
GNU GSRC provides an easy way to do so
Link: http://www.gnu.org/software/gsrc/
After configuration, simply specify the following commands:
cd gsrc make -C pkg/gnu/gcc make -C pkg/gnu/gcc install The second step could also be changed to speed up for an N-core system:
make -C pkg/gnu/gcc MAKE_ARGS_PARALLEL="-jN" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
