[Ipopt] compiling JIPOPT

[Joris Kinable]

Dear Tony,

Thanks, that resolved the problem! My Ipopt works great via the Java
interface under Kubuntu 11.10  (64 bit).

So in summary, if you get the following error:

========================
/opt/ipopt/build/Ipopt/contrib/JavaInterface$ make
g++ `echo -O3 -pipe -DNDEBUG -pedantic-errors -Wparentheses -Wreturn-type
-Wcast-qual -Wall -Wpointer-arith -Wwrite-strings -Wconversion
-Wno-unknown-pragmas -Wno-long-long   -DIPOPT_BUILD | sed -e
s'|-pedantic-errors||'`  -Wl,--rpath -Wl,/opt/ipopt/build/lib -shared -o
lib/libjipopt.so jipopt.o
`PKG_CONFIG_PATH=/opt/ipopt/build/lib64/pkgconfig:/opt/ipopt/build/lib/pkgconfig:/opt/ipopt/build/share/pkgconfig:
/usr/bin/pkg-config --libs ipopt`
/usr/bin/ld: jipopt.o: relocation R_X86_64_32S against `vtable for Jipopt'
can not be used when making a shared object; recompile with -fPIC
jipopt.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [lib/libjipopt.so] Error 1
=========================

You have to recompile Ipopt. Instead of running the default "../configure",
use this command:
../configure ADD_CXXFLAGS="-fPIC"

Next, continue by running make, make test, and finally make install as is
elaborated in the installation manual.

Thanks again,

Joris

Btw, is this mailing list being indexed by Google? I.e, if others have a
similar problem, will they find this e-mail conversation?
