Hi, I’m trying to install FreeFEM++ on my laptop.

OK, I tried the set of instructions given in [http://jolivet.perso.enseeiht.fr/FreeFem-tutorial/main.pdf](http://jolivet.perso.enseeiht.fr/FreeFem-tutorial/main.pdf) Again, errors appear in make -j4, attached is the config.log [config.log](https://community.freefem.org/uploads/short-url/vb3dF0S0DH3ikrXr1gl4ZoFBrYP.log) (352.9 KB) f ---

Another try with the \*deb file.

The `.deb` will not work on Linux Mint. Your library installed FFTW3 is messed up (does not support shared library), so you should add `--disable-system-fftw --disable-download_fftw`, then reconfigure and recompile. ---

What is the output of `make`? ---

I don’t see any particular error there. What is the error you are currently getting? ---

Here are the issues I’m having when I run: 1. Everything has \*dpkg-new appended at the end, so for example /usr/local/lib/ff++/4.6/lib/scotch.so.dpkg-new. 2. Serial code fails to plot: sh: 1: ffglut: not found. Maybe also related to \*dpkg-new issue. 3. Parallel run: **FreeFem+±mpi.dpkg-new -np 4 File2\_MPI.edp** gives **– FreeFem++ v4.6 (Thu Apr 2 15:47:38 CEST 2020 - git v4.6)** **sh: 1: ffglut: not found** \*\* Load: lg\_fem lg\_mesh lg\_mesh3 eigenvalue parallelempi \*\* \*\* Error opening file -np in: \*\* \*\* – try :“-np”\*\* \*\* – try :“/usr/local/lib/ff++/4.6/include/-np”\*\* \*\* Error line number 1, in file – unkown --, before token \*\* **lex: Error input opening file \*\* \*\* current line = -1 mpirank 0 / 1** **Compile error : lex: Error input opening file \*\* \*\* line number :1, \*\* terminate called after throwing an instance of ‘ErrorCompile’ \*\* what(): Compile error : lex: Error input opening file \*\* \*\* line number :1,** 1.

You are not using the version you just compiled, so of course it’s not working. You need to remove everything that is not related to your latest installation that should work. ---

It seems to be working, thank you!
