Hello everyone, I’m having a problem with make check in the installation of FreeFEM on Ubuntu 23.10. When I do the command make -j4 check, I get the following error: ```auto Making check in 3dSurf make[2]: Entering directory '/home/sgau/lib/FREEFEM/examples/3dSurf' make check-TESTS make[3]: Entering directory '/home/sgau/lib/FREEFEM/examples/3dSurf' make[4]: Entering directory '/home/sgau/lib/FREEFEM/examples/3dSurf' PASS: buildMeshSfromMesh3.edp PASS: glu3DSurf.edp PASS: Laplace3dSP2.edp PASS: LaplacianSurf.edp PASS: operatorsOnMeshS.edp PASS: extractSurfFromMesh3.edp ../../bin/test-driver-ff: line 126: 54197 Segmentation fault (core dumped) ${TEST_FFPP} ${FLAGS_FFPP_B} "$@" ${FLAGS_FFPP_A} > $log_file 2>&1 FAIL: testvtk.edp PASS: LapP1withflux.edp PASS: cauchyproblem.edp PASS: periodicS.edp PASS: Connectivite-S.edp PASS: LaplaceRT1Surf.edp PASS: buildmeshS.edp PASS: HeatTorus.edp PASS: Pinocchio.edp ============================================================================ Testsuite summary for FreeFEM 4.14 ============================================================================ # TOTAL: 15 # PASS: 14 # SKIP: 0 # XFAIL: 0 # FAIL: 1 # XPASS: 0 # ERROR: 0 ============================================================================ See examples/3dSurf/test-suite.log Please report to frederic.hecht@sorbonne-universite.fr ============================================================================ ``` In the testsuite.log file there is written the following: ```auto ================================================== FreeFEM 4.14: examples/3dSurf/test-suite.log ================================================== # TOTAL: 15 # PASS: 14 # SKIP: 0 # XFAIL: 0 # FAIL: 1 # XPASS: 0 # ERROR: 0 .. contents:: :depth: 2 PASS: buildMeshSfromMesh3.edp ============================= -- FreeFem++ v4.14 (Tue Dec 26 09:55:30 AM CET 2023 - git no git) file : ./buildMeshSfromMesh3.edp Load: lg_fem lg_mesh lg_mesh3 eigenvalue 1 : load "msh3" 2 : //load "medit" 3 : 4 : //load "gmsh" 5 : //load "iovtk" 6 : 7 : int n= 10; 8 : int nvb = (n+1)^3 - (n-1)^3;// Nb boundary vertices 9 : int ntb = n*n*12; // Nb of Boundary triangle 10 : mesh3 Th=cube(n,n,n); 11 : Th = buildBdMesh(Th); // build the surface mesh 12 : 13 : 14 : int[int] ref2=[1,0,2,0]; 15 : mesh3 Thm=change(Th,label=ref2); 16 : 17 : 18 : meshS Th1 = Th.Gamma; 19 : 20 : assert(Th1.nv==602); 21 : assert(Th1.nt==1200); 22 : assert(Th1.nbe==120); 23 : 24 : plot(Th1); 25 : savemesh(Th1, "Th1.mesh"); 26 : 27 : meshS Th2 = readmeshS("Th1.mesh"); 28 : 29 : assert(Th1.nv==Th2.nv); 30 : assert(Th1.nt==Th2.nt); 31 : assert(Th1.nbe==Th2.nbe); 32 : sizestack + 1024 =1896 ( 872 ) -- Cube nv=1331 nt=6000 nbe=1200 kind= 6 Build meshS from mesh3....

I will try under ubuntu machine to see but my ubuntu see 20.04 Can you launch under gdb to see where is the error? ---

I tried the following command make check RUNTESTFLAGS=“–target\_board=native-gdbserver” FORCE\_PARALLEL=1, but I cannot see the error. Is there another command in linux to launch under gdb? I’m sorry, but I’m not so expert on the use of gdb. ---

ON the machine where you do the compilation. first try on a terminal , if the command gdb is install by enter gdb in the command line terminal. after go in the source directory afetr do cd examples/3dSurf/ # to try without freefem++ ../../src/FreeFem++ ./buildMeshSfromMesh3.edp -nw # to try with the debugger gdb ../../src/FreeFem++ ./buildMeshSfromMesh3.edp -nw run ---
