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
