Dear all, I am trying to install lpsymphony on my Mac. I have homebrew installed with g++-8. R, by default, used clang++.
Backstory: I tried using the default setup, but got an Installing lpsymphony on Mac OS X. I think it may be that there has to be two spaces after -TP, as I noticed other clang++ commands with -TP worked all right, but there was always two spaces after it. I'm not sure, if it's that or something else.
Making no progress with that, having tried a variety of alterations, I am trying to use g++ by altering the ~/.R/Makevars to:
and trying to install lpsymphony that way. Unfortunately, I am getting the error message:
make: Nothing to be done for `install-data-am'. touch SYMPHONY.ts g++-8 -I"/usr/local/Cellar/r/3.5.1/lib/R/include" -DNDEBUG -ISYMPHONY/include -I/usr/local/opt/gettext/include -I/usr/local/opt/readline/include -I/usr/local/include -fPIC -ggdb -O2 -c ._lp_symphony.cc -o ._lp_symphony.o ._lp_symphony.cc:1:1: warning: null character(s) ignored Mac OS X 2 � � ATTR � � < � < com.apple.quarantine q/0081; ....
and was wondering what is going on here. It seems strange that it is compiling a hidden file. One thing is that if I get out of R, download lpsymphony, and go into the symphony directory, I can do ./configure and make and all is well using the clang++ compiler. I am guessing this is some sort of configuration problem, either in Makevars or I have to pass something correctly to install.packages("[filename]", repos = NULL, type = "source").
Any thoughts you have on either this error or perhaps getting it to work with the clang++ compiler would be much appreciated. Many thanks.
