I'm preparing for upcoming GCJ Finals. This year GCJ supports only Linux, and I want to learn how to compile solutions on Linux (I think I used it 9 years ago in IOI but completely forgot how to do that...).

Suppose that A.cpp, Main.java, A.py are source codes, A.in is the input, and you want to output to A.out.

On Windows+Cygwin, I usually do the following:

• g++ -Wl,--stack,268435456 A.cpp -O2 < A.in | tee A.out
• javac Main.java
• java Main < A.in | tee A.out
• python A.py

What commands do the same things on Linux?

The following things are installed on the machine:

• Debian Linux 9.4
• C++ 6.3.0
• Java 7 2.2.5
• Python 2 2.7.13
