[Ipopt] MATLAB crash

[Tony Kelman]

The stack trace you provided looks like it was coming from algencan (and 
from May?), not ipopt.

Regardless, it's not a good idea to tell Matlab to use the version of 
libstdc++ from your operating system. Depending what release of Ubuntu 
you're running, your default GCC version is likely quite a bit newer, and 
binary incompatible, with the version Mathworks recommends. See 
http://www.mathworks.com/support/compilers/R2012a/glnxa64.html

What's probably easiest is to install the older GCC compilers with (I'm 
hoping you have install rights on this machine, otherwise you can build GCC 
from source but that takes quite some time)
sudo apt-get install gcc-4.4 g++-4.4 gfortran-4.3
It looks like gfortran-4.3 might not be available quickly through apt-get in 
the most recent Ubuntu releases, you can try gfortran-4.4 and things might 
still work. Tell ipopt configure to use these compiler versions by 
specifying CC=gcc-4.4 CXX=g++-4.4 F77=gfortran-4.4 (or 4.3).

Are you telling ipopt configure specifically to use a preinstalled coinhsl 
shared library? You're probably better off building the coinhsl source along 
with Ipopt and linking the libraries statically. As long as you have the 
coinhsl source under ThirdParty/HSL/coinhsl, and are using the site script 
which sets --disable-shared, you shouldn't need a shared libcoinhsl.

I had recently wanted to test the ipopt mex with ma97. I downloaded ipopt
3.11, installed all the third party software, coinhsl, copied the .site
file, as described in the installation instructions, into build/share. I
saw that the configuration and make recognizes all the linear solvers I
have available and goes error-free.

First, in order to be able to even run ipopt in matlab, I need to call
matlab as such:
LD_PRELOAD="/usr/lib/x86_64-linux-gnu/libstdc++.so.6
/usr/local/lib/libcoinhsl.so.0" /usr/local/MATLAB-R2012a/bin/matlab


Otherwise matlab, upon attempting to run ipopt, returns an error saying
that it cannot find these libraries that I now preload.

Once I run it like this and run ipopt, with any linear solver, MATLAB
crashes, with the details below.


I am not sure as to what could be causing this. I am using ubuntu, and
others with ubuntu have had no trouble installing and using the ipopt mex.

Thank you
