Successful Compiling ARM64 Android via Termux

[defencedog]

Well I couldn't install ipopt as Android lacks fortran compilers & workarounds are beyond me. All were installed in /usr/local What i can install successfully are papilo. A bug is resolved as well

git clone https://github.com/scipopt/papilo.git
cd papilo 
https://github.com/scipopt/papilo/issues/20
export LDFLAGS="-llog" && cmake -DCMAKE_INSTALL_PREFIX=$PREFIX/local .. && make -j8 && make install

soplex was as well installed

git clone https://github.com/scipopt/soplex.git
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=$PREFIX/local -DPAPILO=on ..

zimpl was as well installed (very good small language). Its source was in the scioptsuite I couldn't find its separate git. On Android will throw error so link libm.so as following

cd scipoptsuite-8.0.1/zimpl/build
ln -s /apex/com.android.runtime/lib64/bionic/libm.so $PREFIX/lib/
cmake -DCMAKE_INSTALL_PREFIX=$PREFIX/local  .. && make -j8 && make install

Finally build scip (I didnt use scioptsuite tar ball except for zimpl)

cd scip-8.0.1
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=$PREFIX/local -DIPOPT=off  ..
make -j8 && make install

Further notes while configuring scip, I had COIN-OR cpl installed in my system but still following gets reported, the documentation doesnt refer how to force-enable it -- Support CLP: OFF

scip -v

SCIP can use several different lp solvers, by default, soplex is used. If you want to use clp as an lp solver, you have to set -DLPS=clp as option to the cmake call: https://scipopt.org/doc/html/md_INSTALL.php#CMAKE

@fschloesser Can you tell which is superior?

[svigerske]

No one is superior :), but SCIP is better tested with SoPlex than with Clp.
