There is no error in the attached file.
sorry, here it is…
config (3).log (431 Bytes)
No error as well… please look at what you are sending before sending it.
@prj I am not sure why what i see on my screen does not show up on config.log but I copied and pasted what i see here when i do make petsc-slepc
UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details):

make: *** [Makefile:215: petsc-3.19.5/tag-conf-real] Error 1
Does the directory /home/fem exists? Could you copy its content here? Do you have enough free space in your VM?
try something like this maybe,
ls -al `find /home -maxdepth 1`
@prj it does exist, I have created it on my vm to be able to use it in --prefix command, rather than saying --prefix=${pwd}. It is empty though, nothing to copy here. I have enough space on my vm this was my two-days ago problem, I increaed the disc space.
Thank you,
If it’s empty, then it means you don’t have the proper credentials. You should stick to a path in which you have the proper read/write access, e.g., a sub-directory not in your ${HOME}.
Hello again. I know the discussion is getting longer but I really want to get the mesh defined at the very begining of this question. @prj I have followed all instructions, created a folder with correct credentials not in my home directory (now it is not empty, it has a folder named ff-petsc and under that tw sub folders named c and r ). Following exactly the steps:
git clone GitHub - FreeFem/FreeFem-sources: FreeFEM source code
cd FreeFem-sources
git checkout develop
autoreconf -i
./configure --enable-download --without-hdf5
–prefix=…
cd 3rdparty/ff-petsc
make petsc-slepc
cd -
./reconfigure
make
I seem to go through the compilation. However when I simply want to run an example .edp file under FreeFem-sources/examples/tutorial and write FreeFem++ Laplace.edp I see the error message saying
Command ‘FreeFem++’ not found, but can be installed with:
sudo apt install freefem++
same error when I use
◦ FreeFem+±mpi
◦ ffglut
◦ ffmedit
◦ ff-c++
how should I run the examples? any comments on that? or where to look for an error ?
Is the folder FreeFem-sources/src/nw in your ${PATH}?
is there a “make install” or “make check” step?
IIRC it did some tests and some point and should have displayed pass/fail
although I may have it mixed up with other software 
I guess to just make the flower mesh you could create each segment of the
boundary individually right?
@prj when I write echo $PATH inside folder FreeFem-sources/examples/tutorial I see
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin
when I do echo $PATH inside folder FreeFem-sources I see the same thing. I guess FreeFem-sources/src/nw is not in my path. Should I add it, if yes, how?
Yes, you should add it. You can look at the end of the tutorial, last slide of Optimal Compilation Process, or do a quick Google search.
Thanks for all the comments and help @prj @marchywka, after adding the path I can run the examples correctly. Now I have other problems as rotating the level set defined geometry and disturbing the mesh , but I might create a new discussion on that.
