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.
