Zooming in more: configure:9679: checking if cc PIC flag -fPIC -DPIC works configure:9697: cc -c -O2 -pipe -fno-strict-aliasing -I/usr/local/include -fPIC -DPIC -DPIC conftest.c >&5 cc: warning: argument unused during compilation: '-L/usr/local/lib' configure:9701: $? = 0 configure:9714: result: no So, exit status is OK, but it still finds result no: if test ! -s conftest.er2 || diff conftest.exp conftest.er2 >/dev/null; the n lt_cv_prog_compiler_pic_works=yes fi The unused argument generates stderr output that makes libtool think it doesn't support it, even though $? is 0. Braindead by design. Adding -Qunused-arguments fixes the issue. I still don't get how it relates to ccache and why adding NO_CCACHE to a port's Makefile fixes things. Is there some magic that adds -Qunused-arguments if CC = clang and that fails to detect that CC=clang when CC=ccache? -- You are receiving this mail because: You are the assignee for the bug.
