And it seems libtool itself is the one who breaks it. This is the failing line again: /bin/sh ../libtool --tag=CC --mode=link cc -g -O2 -fstack-protector-strong -Wall -Wmissing-prototypes -Wstrict-prototypes -avoid-version -module -L/usr/local/lib -Wl,--as-needed -o sox sox.o libsox.la -lm Notice the "-L/usr/local/lib -Wl,--as-needed". The "-L/usr/local/lib" part comes from the configure arg: ./configure CC=cc CPPFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib The "-Wl,--as-needed" comes from $ grep as-needed configure.ac AX_APPEND_LINK_FLAGS([-Wl,--as-needed]) That results in the following line in src/Makefile: LDFLAGS = -L/usr/local/lib -Wl,--as-needed and that's what is passed in the above command line. Now, libtool apparently preprocesses the line into something else; in particular, it reorders the options. The very next command is: libtool: link: cc -g -O2 -fstack-protector-strong -Wall -Wmissing-prototypes -Wstrict-prototypes -Wl,--as-needed -o .libs/sox sox.o -L/usr/local/lib -L./.libs -lsox -lpng -lltdl -lao -lgsm -lmad -lmp3lame -ltwolame -lid3tag -lz -lopusfile -lopus -lsndio -lvorbisfile -lwavpack -lcrypto -lsndfile -lFLAC -lvorbisenc -lvorbis -logg -lm -Wl,-rpath,/usr/local/lib Notice where the -L/usr/local/lib has been moved. As described previously, if it comes after -lsox instead of before it, it links just fine. _______________________________________________ SoX-devel mailing list SoX-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sox-devel
