The judge system use the following commands internally to compile and run the submitted programs. These commands are also available on your workstation.
| C | compilegcc(no “run” command) |
| C++ | compileg++(no “run” command) |
| Java | compilejava / runjava |
| Python3 | compilepython3 / runpython3 |
| Kotlin | compilekotlin / runkotlin |
For your reference, below are how your programs will be compiled and run. ”$@” is substituted with your source file(s); ”$DEST” is the name of the binary (which is “./a.out” by default) and is chosen arbitrarily by the system.
| C | |
| Compile | gcc -x c -g -O2 -std=gnu11 -static -o"$DEST" "$@" -lm |
| Run | "$DEST" < infile > outfile |
| C++ | |
| Compile | g++ -x c++ -g -O2 -std=gnu++20 -static -o"$DEST" "$@" |
| Run | "$DEST" < infile > outfile |
| Java | |
| Compile | javac -encoding UTF-8 -sourcepath . -d . "$@" |
| Run1 | java -Dfile.encoding=UTF-8 -XX:+UseSerialGC -Xss64m -Xms1920m -Xmx1920m MainClass < infile > outfile |
| Python 3 (PyPy) | |
| Compile2 | /usr/local/py3-venv/bin/pypy3 -m py_compile "$@" |
| Run | /usr/local/py3-venv/bin/pypy3 "$@" < infile > outfile |
| Kotlin | |
| Compile | kotlinc -d . "$@" |
| Run1 | kotlin -Dfile.encoding=UTF-8 -J-XX:+UseSerialGC -J-Xss64m -J-Xms1920m -J-Xmx1920m MainClass < infile > outfile |
Note:
1: DOMjudge will detect the main class automatically; you do not have to name it Main. See the DOMjudge team manual for details.
2: Python’s “Compile” command only verifies the syntax. *.pycfiles will not be used in the real run.
