[gecode-users] Gist - linking error

[Christian Schulte]

Please read how to link your program: like all other libraries you already
link against (-lgecodeint, ...) you also have to link against libgecodegist
(-lgecodegist).

If the problem pertains - as your message suggests - did you actually build
the Gist library? Do you have the required Qt libraries installed?

Christian

Subject: [gecode-users] Gist - linking error


Hi all,

I am trying to use Gist (in stand alone mode) to explore the search tree of
my CSP, but unfortunately, I cannot get it to work.
Without Gist, the CSP is solved as expected.

I just added:

#include <gecode/gist.hh>

and then called Gist::dfs on my Space object.

When I compile, I get:

c++   RCG.cc -o RCG -lgecodeint -lgecodeset -lgecodesearch
/tmp/cc7peTxn.o: In function `Gecode::Gist::dfs(Gecode::Space*,
Gecode::Gist::Options const&)':
RCG.cc:(.text._ZN6Gecode4Gist3dfsEPNS_5SpaceERKNS0_7OptionsE[Gecode::Gist::d
fs(Gecode::Space*, Gecode::Gist::Options const&)]+0x1c): undefined reference
to `Gecode::Gist::explore(Gecode::Space*, bool, Gecode::Gist::Options
const&)'
/tmp/cc7peTxn.o: In function `RCG::doSearch(RCG*)':
RCG.cc:(.text._ZN3RCG8doSearchEPS_[RCG::doSearch(RCG*)]+0x3a): undefined
reference to `Gecode::Gist::Options::def'
collect2: ld returned 1 exit status
make: *** [RCG] Error 1

I tried to link against any gecode library, the result remains the same.

Cheers,

Yannick
