<br>
when we added these compiler flags, we were not aware that they would create trouble with such old GCC versions, sorry for that. For now the attached patch should fix your problem. (Hopefully: I have no way to test it quickly.) Please let us know, whether it works.<br>
<br>
Kind regards,<br>

Hi All,<br>
<br>
I am trying to compile SCIP on a server with gcc version 4.1.2<br>
Based on the instructions specified on the website and the INSTALL text<br>
file, I tried compiling SCIP using CPLEX as the LP solver with the<br>
following (most compatible) set of flags:<br>
<br>
make ZLIB=false GMP=false READLINE=false LPS=cpx LPSOPT=opt-gccold<br>
OPT=opt-gccold<br>
<br>
When I tried compiling, this is the error which terminates the compilation:<br>
<br>
******************************<u></u>******************************<u></u>******************************<u></u>***********************<br>
-> compiling obj/O.linux.x86_64.gnu.opt-<u></u>gccold/lib/objscip/<u></u>objbranchrule.o<br>

<br>
Could you please help me figure out how I can compile SCIP on this<br>
machine ? I was able to successfully compile and implement some code on<br>
a different machine with gcc version 4.4.7, but now I need to compile my<br>
code on this machine with an older version of gcc.<br>
<br>
Thank you very much,<br>
<br>
