[Ipopt] Problem with MA27

[Epenoy Richard]

Dear colleagues,

When installing Ipopt, the test programs  failed.

This comes from the MA27 routine from the HSL library that cannot be found:


    ******** Test FAILED! ********
Output of the test program does not contain 'EXIT: Optimal Solution Found'.
Testing sIpopt Example parametric_cpp...
./run_unitTests: line 19: 345541 Segmentation fault      $@ > tmpfile 2>&1
0
 ---- 8< ---- Start of test program output ---- 8< ----
Exception of type: OPTION_INVALID in file "/home/eh/epenoyr/Ipopt/src/Algorithm/IpAlgBuilder.cpp" at line 268:
 Exception message: Selected linear solver MA27 not available.
Tried to obtain MA27 from shared library "libhsl.so", but the following error occured:
libhsl.so: cannot open shared object file: No such file or directory

EXIT: Invalid option encountered.
 ---- 8< ----  End of test program output  ---- 8< ----


Could you please tell me how to download the missing routinr?

Best
