the SCIP makesystem should ask you for the link. Try running<br>

make IPOPT=true links<br>

Hi, thanls Ambros and Hans for the reply.<br>
<br>
I installed and compiled IPOPT. I am not being able to install SCIP with<br>
IPOPT, I tried to reinstall scip like you said:<br>
<br>
make IPOPT=true<br>
<br>
But I don't know where do I provide the link to IPOPT libraries. I get the<br>
error:<br>
<br>
src/nlpi/nlpi_ipopt.cpp:45:25: fatal error: IpoptConfig.h: No such file or<br>

compilation terminated.<br>
make[2]: *** [obj/O.linux.x86_64.gnu.opt/<u></u>lib/nlpi/nlpi_ipopt.o] Error 1<br>
<br>
Do you know how to proceed?<br>
<br>
Thank you very much and sorry if this is stupid,<br>
Cristiano<br>

Hi Cristiano,<br>
<br>
exactly, your installation seems to miss Ipopt. You have to use "make<br>
IPOPT=true" when compiling SCIP and provide the link to the build directory<br>
of your Ipopt installation.<br>
<br>
Best regards,<br>

Hi again,<br>
<br>
I've been using the NEOS server to test SCIP and I've been impressed<br>
with its speed. I tried solving 36 nonlinear instances and the largest<br>
one can be downloaded here:<br>

It takes NEOS SCIP 6 seconds to solve it. I am using the same scip.set<br>
parameters file that can be found on NEOS. I installed the SCIP<br>
optimization suite following the steps in the link provided in the first<br>
message of this thread.<br>
<br>
I know my PC is slower than the NEOS server but SCIP on my PC has been<br>
solving the same instance for 1200s. In the output file I get this<br>
message:<br>

Do you know why I cannot reproduce such results? Might I be missing<br>

Hi,<br>
<br>
what is not supported so far is to set SCIP options via the AMPL<br>
script language.<br>
However, AMPL/SCIP reads by default SCIP options from the file<br>
scip.set, if present.<br>
<br>
Alternatively, one can specify a SCIP settings file as argument<br>
to the AMPL/SCIP binary. However, that would require to write<br>
out the AMPL model as .nl file first and to run the binary<br>
explicitly, e.g.,<br>
./bin/scipampl <a href="http://foo.nl" target="_blank">foo.nl</a> <<a href="http://foo.nl" target="_blank">http://foo.nl</a>> myoptions.set<br>
<br>
<br>
Btw, adding "-i" to the command line arguments gives you the<br>
SCIP interactive shell.<br>
<br>
Hope that helps,<br>
Stefan<br>

In the tutorial it is said that no SCIP options are<br>
currently supported. Do<br>
you know if there is a way to use options with AMPL or if<br>
there is an<br>
alternate way to do this, for example, by presenting an<br>
options file?<br>
<br>
Thank you very much,<br>
