Hi, I am having some trouble building getFEM++(version 4.1.1) on my macbook pro (version 10.5.8). The compilers used are i686-apple-darwin9-gcc-4.0.1 and i686-apple-darwin9-g++-4.0.1. Here are the steps I take:
./configure --with-blas=/System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Versions/Current/libBLAS.dylib --disable-python make make check The build is successful, but one of the tests failed: ============================================ | An error has been detected !!! | ============================================ Error in getfem_nonlinear_elasticity.cc, line 337 : Derivative test has failed FAIL: ../tests/nonlinear_elastostatic.pl The full output of the test is: ./nonlinear_elastostatic nonlinear_elastostatic.param MESH_TYPE=GT_PK(3,1) FEM_TYPE=FEM_PK(3,2) INTEGRATION=IM_TETRAHEDRON(6) Selecting Neumann and Dirichlet boundaries Test 74 wrong derivative of sigma, i=0, j=0, dsigma=-733.283, var sigma = -733.431 Test 90 wrong derivative of strain_energy, d=1.47731e+07, d2=1.47716e+07 Test 90 wrong derivative of sigma, i=0, j=0, dsigma=-7.06813e+11, var sigma = -7.06932e+11 Test 90 wrong derivative of sigma, i=0, j=1, dsigma=1.26474e+12, var sigma = 1.26495e+12 Test 90 wrong derivative of sigma, i=0, j=2, dsigma=6.45419e+11, var sigma = 6.45529e+11 Test 90 wrong derivative of sigma, i=1, j=0, dsigma=1.26474e+12, var sigma = 1.26495e+12 Test 90 wrong derivative of sigma, i=1, j=1, dsigma=-2.26302e+12, var sigma = -2.2634e+12 Test 90 wrong derivative of sigma, i=1, j=2, dsigma=-1.15495e+12, var sigma = -1.15515e+12 Test 90 wrong derivative of sigma, i=2, j=0, dsigma=6.45419e+11, var sigma = 6.45529e+11 Test 90 wrong derivative of sigma, i=2, j=1, dsigma=-1.15495e+12, var sigma = -1.15515e+12 Test 90 wrong derivative of sigma, i=2, j=2, dsigma=-5.89172e+11, var sigma = -5.89272e+11 ============================================ | An error has been detected !!! | ============================================ Error in getfem_nonlinear_elasticity.cc, line 337 : Derivative test has failed Computing nonlinear elasticity accurately is important for my project. Any suggestions on how to fix this? Thanks a lot! James
