I am trying to compile a simple a hello world QBASIC program in ubutu 12.04. Compiler is downloaded and installed as instructed here. http://www.freebasic.net/get
Also I posted it on askubuntu.com https://askubuntu.com/questions/226084/free-basic-compiler-error-23-file-not-found-libsupc-a#comment279100_226084 but reported to post here. Here is my simple QBASIC program and compilation details.
print "hello word"
I compiled it with
fbc hello.bas
But I got the following error.
hello.bas() error 23: File not found, libsupc++.a
ld: cannot find -lncurses ld: cannot find -lsupc++
回答1:
Your system lacks dependencies required by fbc. At least one package is missing. libsupc++ is part of libstdc++ which is installed when installing g++.
Have a look at the list at http://www.freebasic.net/wiki/wikka.php?wakka=CompilerInstalling
On Ubuntu you will need at least these packages:
- gcc, g++
- libncurses5-dev
- libx11-dev, libxext-dev, libxrender-dev, libxrandr-dev, libxpm-dev
- libffi-dev
You can install them using apt-get or aptitude or a GUI package management tool of your choice.
