But it crashes telling me it needs libhsl.so whereas my buid created a lib called libcoinhsl.so<br><br>I'm on a linux-64 platform (ubuntu 12.04)<br>I'm running Matlab R2012a <br>I'm using gcc-4.4 g++-4.4 and gfortran-4.4 to compile all the parts of the source code. <br>I have BLAS ans LAPACK installed<br><br>here is the ./configure line i'm using : <br><br>./configure --prefix=$HOME/ipopt/install CXX=g++-4.4 CC=gcc-4.4 F77=gfortran-4.4 ADD_CXXFLAGS="-fPIC -fexceptions" ADD_CFLAGS="-fPIC -fexceptions" ADD_FFLAGS="-fPIC -fexceptions"<br><br>I should mention that I tried changing the name of the ThirdParty build from libcoinhsl to libhsl but it couses matlab to crash.<br><br>I tried to use MUMPS instead but the same problem occurs.<br><br>Do you have any idea about what I'm doing wrong ? <br><br>Thank you very much <br>Jérémy Sinoir <br><br><br><br><br></div></body></html>
