Seems so:
cc -g -O2 -fstack-protector-strong -Wall -Wmissing-prototypes -Wstrict-prototypes -fstack-protector-strong -Wl,--as-needed -o .libs/sox sox.o -L/usr/local/lib -L./.libs -lsox -lpng -lltdl -lao -lgsm -lid3tag -lz -lmad -lmp3lame -ltwolame -lopusfile -lopus -lsndio -lvorbisfile -lwavpack -lcrypto -lsndfile -lFLAC -lvorbisenc -lvorbis -logg -lm -Wl,-rpath,/home/hans/lib -Wl,-rpath,/usr/local/lib
fails, but
cc -g -O2 -fstack-protector-strong -Wall -Wmissing-prototypes -Wstrict-prototypes -fstack-protector-strong -Wl,--as-needed -o .libs/sox sox.o -L./.libs -lsox -L/usr/local/lib -lpng -lltdl -lao -lgsm -lid3tag -lz -lmad -lmp3lame -ltwolame -lopusfile -lopus -lsndio -lvorbisfile -lwavpack -lcrypto -lsndfile -lFLAC -lvorbisenc -lvorbis -logg -lm -Wl,-rpath,/home/hans/lib -Wl,-rpath,/usr/local/lib
succeeds. The only difference between the two is the -L order, namely,
cc [...] -o .libs/sox sox.o -L/usr/local/lib -L./.libs -lsox -lpng [...]
cc [...] -o .libs/sox sox.o -L./.libs -lsox -L/usr/local/lib -lpng [...]
That confirms my suspition the ./configure LDFLAGS=-L...
puts the extra -L in a wrong place. Running ./configure
without options, on the other hand, detects e.g. flac
and puts the -L/usr/local/lib at the right place in that line.
