<tt>Dear Michael,<br>
<br>
as far as I can tell, GCG shipped with previous releases can only
be built when SCIP is also built using the Makefile (so without
cmake). This will change with the next release (coming soon), in
which GCG can be built with cmake, too.<br>
<br>
Until then, the following workaround worked for me:<br>
<br>
1. Compile gcg with `make SHARED=true`.<br>
2. As long as this triggers any errors on missing SCIP-related
shared libraries (such as libscip, libtpi*, liblpi*,
libobjscip...), created the desired ones (for me it was looking in
scip/lib/shared/ for them) as symlinks to the cmake-built shared
library libscip.so.<br>
<br>
This is really a hack, since the linker for GCG will link to
libscip.so several times, but it seems to be clever enough to
figure out the duplicates.<br>
<br>
Sorry for the inconvenience, but I guess this will be better with
the upcoming release!<br>
<br>
Best,<br>
Matthias<br>
