Compiles fine but no graphics in Freefem++ executable (V4)

FreeFEM installation
1

I compile the new v4 with:
./configure --prefix=/media/ali/extra/install/ffm4.0 --enable-download --with-mpi=no --disable-generic --disable-system-blas --disable-system-umfpack --disable-mshmet --disable-pipe --disable-tetgen --disable-hips --disable-ipopt --disable-parmetis --disable-gmm --disable-nlopt --disable-parms --disable-pastix --disable-pipe --disable-scotch --disable-yams --disable-MMAP --disable-pardiso --disable-hpddm --disable-mmg3d CFLAGS=-march=native CXXFLAGS=-march=native FCFLAGS=-march=native FFLAGS=-march=native

No error, however the Freefem++ executable doesn’t show any plot and acts just like Freefem+±nw exec. I have been using these options for every release so far without any problems.

the reason is ffglut is not compile general

att the end of configure you have a message like:

     *********************************************** 
     WARNING: you do not have the new grachics tools 
         because the configure do not find OpenGL, GLUT or pthread  developer stuff 
         read the README to find missing package  
         F. Hecht  ])
 to install missing package  under debian or ubuntu, try: sudo apt-get install freeglut3-dev ])
     ***********************************************

see https://doc.freefem.org/introduction/installation.html#compilation-on-ubuntu
for example;

Thanks, I don’t get the warning at the end of configure. Actually I have compiled v3.61 and it works fine. I think the best way is to attach the config.log. Unfortunately looks it’s not possible to attache a file to a post. Here is the summary I get at the end of config:

configure:22637:   freefem++ used  download : yes 
configure:22639: 	--  Dynamic load facility: yes

the raison is ffglut v 4 is not compatible with version 3.xx due to surface element
so please install the new ffglt of version 4. to replace the old one.

Thanks, you mean the new version of freeglut? Right now I have freeglut3 installed which looks to be the latest version of the freeglut library.

No change the ffglut by the new version in src/nw/ffglut

MBP-FH5:ff-git hecht$ which ffglut

/usr/local/ff++/openmpi-2.1/4.1/bin/ffglut

Worked, thanks! Also I tried the latest release of V4.2 and the problem is fixed
