Oh, yes. I got your point.

I will try to inform the arguments.

Thank you, for now.

Wilmar.

Hi. I’m here again!

I create the CMakeLists.txt:

I create the CMakeLists.txt:

# CMake script

# Set the name of the project and target:

SET(TARGET “main”)

# Declare all source files the target consists of:

SET(TARGET\_SRC  
${TARGET}.cc  
)

CMAKE\_MINIMUM\_REQUIRED(VERSION 2.8.8)  
PROJECT(${TARGET})

After that I put the command:

administrador@administrador-desktop:~/cpp$ cmake CMakeLists.txt  
– The C compiler identification is GNU 7.3.0  
– The CXX compiler identification is unknown  
– Check for working C compiler: /usr/bin/cc  
– **Check for working C compiler: /usr/bin/cc - broken**  
CMake Error at /usr/share/cmake-3.17/Modules/CMakeTestCCompiler.cmake:60 (message):

The C compiler is in the “/usr/bin/ **cc** ”, but is not able to compile a simple test program.

I confirm that **cc** is in the /usr/bin:

administrador@administrador-desktop:/usr/bin$ **ls -lag cc**  
lrwxrwxrwx 1 root 20 set 9 2018 cc -\> /etc/alternatives/ **cc**

I didn’t understand why it was listed on **/etc/alternatives** directory. I have to put this on PATH?

I finish cmake instalation. The problem is that the 2 GByte PC RAM is insufficient to run Finite Element Analise. I turn to another PC, with 4 GByte.

O though that I manage to install once, repeat will be ease! I was wrong!

I proceead to cancel directory **cmake-3.17.2** and do everything again, but didn’t function!  
It was ok for:  
wilmar@wilmar-G31M-ES2C:~$ **sudo apt-add-repository 'deb bionic main’**

but was bad for:  
wilmar@wilmar-G31M-ES2C:~$ **sudo apt-get update**

Maybe I did many errors!

Craig or Kyle Edwards, or others could help a desperate student?

P.S.: I need to proceed with the Deal.ii too. A long journey to get there…
