Permasalahan: ketika kompilasi software dengan compiler icpc (Intel oneAPI DPC++/C++ Compiler) terjadi pesan kesalahan berikut ini:
fatal error: 'iostream' file not found

Sumber permasalahan: icpc memerlukan file library stream dan sebagainya dari g++. 
Solusi: install g++ versi yang agak baru misal versi 10, kemudian lakukan kompilasi seperti biasa.
