Hi to evrywhon who can help me;

Look at my problem here....See the crash when i tried to Build the program.

/home/mark007/ImperatiefPro/05 Hoofdstuk Operatoren en Expressies/5.1 Operatoren/5.1.1 Rekenekundige operatoren/Ls. 5.1-Opsl/build> /usr/bin/cmake -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Debug '/home/mark007/ImperatiefPro/05 Hoofdstuk Operatoren en Expressies/5.1 Operatoren/5.1.1 Rekenekundige operatoren/Ls. 5.1-Opsl/'

CMake Warning (dev) in CMakeLists.txt:
No cmake_minimum_required command is present. A line of code such as

information run "cmake --help-policy CMP0000".

*** Mislukking: Exitcode 1 ***

The issue is resolved, the software was written in C style old school.
Therefore, the system asked for one older version Compiler.

My apologies
