Does it get ncurses to auto-disable the C++ stuff? I guess not: cd ../objects; false -I../c++ -I../include -I. -DHAVE_CONFIG_H -DNDEBUG -I. -I../include -I/home/ibid/test/ncurses/include -c ../c++/cursesf.cc make[1]: *** [../objects/cursesf.o] Error 1 make[1]: Leaving directory `/home/ibid/misc/src/musl/ncurses-5.9/c++' make: *** [all] Error 2 There are many other packages that do need that.

OK, configure --help lies about its behavior. Use --includedir=$prefix/include Anyhow... re: pcc: Probably the best thing if you want to link programs with a shared musl using pcc is to patch & recompile. It hard-codes the dynamic linker; -dynamic may work. You must rm -r musl/src/complex/ to build musl with pcc.
