delete the .so files from $OSICBC_HOME/lib before you link your executable, or link with -static.<br>

It links now! But:<br>

mzn-cbc: error while loading shared libraries: libCgl.so.0: cannot open<br>

I compiled cbc as follows:<br>

I'm pretty sure this is a link order problem. If you modify the link<br>
order to<br>
<br>
-lCbcSolver -lCbc -lCgl -lOsiClp -lClpSolver -lClp -lOsi -lCoinUtils<br>
<br>
I'm guessing the problem will go away. I had forgotten that I guess<br>
this was only a problem with static libraries.<br>

Hi Ted,<br>
<br>
the linker does not really find any functions in the libraries,<br>
although it finds all the .a files. The relevant part of cmake's<br>
output is attached. Here are the contents of CBC's lib directory:<br>
<br>
bg@bg-vbox:/media/sf_SHARED/prj/libmzn/build$ ls $OSICBC_HOME/lib<br>
libCbc.a libCbcSolver.a libCgl.a libClp.a libClpSolver.a<br>
libCoinUtils.a libOsi.a libOsiCbc.la libOsiClp.la<br>
libOsiCommonTests.la pkgconfig<br>
libCbc.la libCbcSolver.la libCgl.la libClp.la libClpSolver.la<br>
libCoinUtils.la libOsiCbc.a libOsiClp.a libOsiCommonTests.a<br>
libOsi.la<br>
<br>
Looking for one of the functions missed, writeMpsNative, gives:<br>
<br>
bg@bg-vbox:/media/sf_SHARED/prj/libmzn/build$ grep writeMpsNative<br>
$OSICBC_HOME/lib/*<br>

As far as I know, there shouldn't be anything special you need to<br>
do in order to link to static libraries in Linux. What's the<br>
error? On Windows, we only support generation of static libraries<br>
at this point, so nothing should be any different there.<br>

Now it works with 2268 without any further changes, thank you.<br>
<br>
Next question: when configuring with --enable-static<br>
--disable-shared, the /lib forlder has only .a (and probably<br>
.la) files and the examples' Makefile is not much different.<br>
However my executable does not link. Is there any specific<br>
link flag in this case? What is under Win?<br>
