[Getfem-users] file error(compilation)

Respected Users,

I have followed following steps
1- first i configure using command given on webpage
2- i make and than make test
3- i make install

(my test report passed 37 out of 38 tests)

after that i want to make some basic program in getfem++, so for understanding the method of writing program i picked one example from
test folder and copied it to /document/test1
i picked two files
laplacian.cc and laplacian.pram

than i have given the following command on my terminal

g++ -o output.o laplacian.cc
(same command is also tried with      'make laplacian' )
follwing list of error generated as below

error

can you help me in understanding the problem. I am not so good in programming at advance level. I there any problem while reading the file from parameter file

Is there also any compiled tutorials for getfem++ using C++ without any interface.

thanking in advance

Dear Asim Ullah Khan,

It should work if you performed a "make install". Can you report the error you got ?

Yves.

Respected group memebers

Is there any detailed guide for getfem with steps to follow for making a fem program. The examples given in test code i tried to compiled them using eclipse but i am not successful. I m newbe to ubuntu and has just shifted from windows.

I am copying test files with parameter file in the seperate folder and than open that file in eclipse CDT for c++ and than try to understand and when i issue the command

$ g++ -std=c++11 inputfilename.cc -o outputfilename.o i get compilation failed although all library files are already in the include folder

(I m using ubuntu 15.10)

Is there any detailed document to describe the step to follow for compiling the files and detailed tutorials set.

Regards

ASIM ULLAH KHAN
