Problem building lpsymphony on macos

[jorainer]

Hi Vlad,

I'm experiencing the following error when installing lpsymphony on macos:

/usr/local/opt/llvm/bin/clang++ -std=gnu++11 -w -g -O2 -DSYMPHONY_BUILD -TP -o symphony symphony-main.o -framework Accelerate -framework Accelerate -framework Accelerate -framework Accelerate -framework Accelerate -framework Accelerate -Wl,-bind_at_load  ./.libs/libSym.a /private/var/folders/fg/g7fr2fs50l3frgx731lv3mjw0000gn/T/RtmpGQLusa/R.INSTALLfd4c6326cd64/lpsymphony/src/SYMPHONY/Cgl/src/.libs/libCgl.a /private/var/folders/fg/g7fr2fs50l3frgx731lv3mjw0000gn/T/RtmpGQLusa/R.INSTALLfd4c6326cd64/lpsymphony/src/SYMPHONY/Clp/src/OsiClp/.libs/libOsiClp.a /private/var/folders/fg/g7fr2fs50l3frgx731lv3mjw0000gn/T/RtmpGQLusa/R.INSTALLfd4c6326cd64/lpsymphony/src/SYMPHONY/Clp/src/.libs/libClpSolver.a /private/var/folders/fg/g7fr2fs50l3frgx731lv3mjw0000gn/T/RtmpGQLusa/R.INSTALLfd4c6326cd64/lpsymphony/src/SYMPHONY/Clp/src/.libs/libClp.a /private/var/folders/fg/g7fr2fs50l3frgx731lv3mjw0000gn/T/RtmpGQLusa/R.INSTALLfd4c6326cd64/lpsymphony/src/SYMPHONY/Osi/src/Osi/.libs/libOsi.a /private/var/folders/fg/g7fr2fs50l3frgx731lv3mjw0000gn/T/RtmpGQLusa/R.INSTALLfd4c6326cd64/lpsymphony/src/SYMPHONY/CoinUtils/src/.libs/libCoinUtils.a

have you any idea how to solve this or could you give me some hint where I could start digging into it?

BTW my R:

Note: I managed to install the package now by modifying the src/SYMPHONY/SYMPHONY/configure.ac and src/SYMPHONY/SYMPHONY/configure files removing the -TP CXXFLAGS (which at least llvm does not seem to support). Without that symphony compiles and I can install the package.
