<p>Hi Joel,</p>
<p>Sorry for my late reply. As Tony mentioned, I am not using
CSPARSE as the linear solver for IPOPT. <span style="font-size:
12px;">KKT matrices arising in IPOPT are indefinite matrices
and CSPARSE can not solve indefinite systems. </span><span
style="font-size: 12px;">CSPARSE has the approximate minimum
degree algorithm in it. I am using this algorithm to change
the ordering of KKT matrices. </span></p>
<p>P.S I realized that my CSPARSE functions were working fine even
before I sent an email to group. A bug in my code was causing
MATLAB crash so if anyone wants to link a third party software
to IPOPT you can use the steps that I explained in my earlier
emails. </p>
<p>Have a great day.</p>

<div>For curiosity, does using CSparse work well together with
IPOPT? Or did you want to avoid the other linear solvers

I was just typing you an email about this. My code was
working fine before therefore I did not even run make
test. After I have started having troubles I have decided
to run make test and you are right it should not work
anyway because I am only adding -lcsparse into the
matlabinterface makefile. I know I am having trouble using
csparse functions because when I command out cparse
functions I can run ipopt from Matlab without any trouble
but when I add those functions my matlab crashes even
before the first ipopt iteration. I am thinking maybe the
problem is about an update I did in my computer (I dont
remember doing any updates either but why would it stop
working if I did not change anything.)

before, or were you just<br>
building the Matlab interface? To run standalone
executables like from<br>
make test then you'll need to add -lcsparse to other
link flags too,<br>
not just in the MatlabInterface folder. I think
there are some ADDLIBS<br>
configure variables you can set for this.<br>

Hi Tony,<br>
<br>
I downloaded Ipopt again did all of these steps
again and it still does<br>
not work. I have also tried adding the changes to
the Makefile.in file.<br>
<br>
@COIN_HAS_PKGCONFIG_TRUE@LIBS =
`PKG_CONFIG_PATH=@COIN_PKG_<span
style="text-decoration: underline;"></span>CONFIG_PATH@<br>
@PKG_CONFIG@ --libs ipopt | sed -e 's/-framework
vecLib//g'` I changed<br>
this line with<br>
<br>
@COIN_HAS_PKGCONFIG_TRUE@LIBS =
`PKG_CONFIG_PATH=@COIN_PKG_<span
style="text-decoration: underline;"></span>CONFIG_PATH@<br>
@PKG_CONFIG@ --libs ipopt csparse | sed -e
's/-framework vecLib//g'`<br>
<br>
and then ran the configure script again but it is
still not working.<br>
<br>

Sounds like you reran configure since you made
that change. Configure<br>
auto-generates the Makefiles from Makefile.in,
overwriting any changes<br>
you made. Try making the change where you add
-lcsparse to LIBS in<br>
Makefile.in instead, then run configure and it
should work again.<br>

Subject: [Ipopt] Using a Third Party Software in
IPOPT MA57 Interface<br>
<br>
<br>
Hello everyone,<br>
<br>
I am trying to use a Third party software in<br>
<br>
<br>
<br>
../CoinIpopt/Ipopt/src/<span
style="text-decoration: underline;"></span>Algorithm/LinearSolvers/<span
style="text-decoration: underline;"></span>IpMa57SolverInterface.cpp.<br>
This third party software is called CSPARSE
which is written by Tim<br>
Davis. I was able to use this software in this
file before but it<br>
stopped working. Obviously I have changed
something somewhere but I<br>
could not find it maybe one of you can think of
anything.<br>
<br>
These are the steps that I am performing right
now.<br>
<br>
1) Compile the third party software and obtain
libcsparse.a library.<br>
2) Copy this library to CoinIpopt/lib folder.<br>
3) Copy the main .h file of CSPARSE (cs.h) to
the same folder with<br>
IpMa57SolverInterface.cpp file which is in<br>
CoinIpopt/Ipopt/src/Algorithm/<span
style="text-decoration: underline;"></span>LinearSolvers
folder.<br>
4) Modify the makefile in
CoinIpopt/Ipopt/contrib/<span
style="text-decoration: underline;"></span>MatlabInterface/src
.<br>
I used to have LIBS = -L/CoinIpopt/lib -lipopt .
I added -lcsparse to<br>
this line.<br>
5) The last step is adding<br>
<br>
extern "C"<br>
{<br>
<br>
#include "cs.h"<br>
<br>
}<br>
<br>
command at the beginning of the
IpMa57TSolverInterface.cpp file.<br>
<br>
As I mentioned before these steps used to work
fine but now when I run<br>
make test it gives me the following error<br>
<br>
Undefined symbols for architecture x86_64:<br>
"_cs_amd", referenced from:<br>
Ipopt::Ma57TSolverInterface::<span
style="text-decoration: underline;"></span>SymbolicFactorization(int
const*,<br>
int const*) in libipopt.a(<span
style="text-decoration: underline;"></span>IpMa57TSolverInterface.o)<br>
<br>
cs_amd is the function that I am trying to use
from CSPARSE software.<br>
<br>
Thank you.</blockquote>
