Re:Linker issues for libssw on armel, mips64el and mipsel

Hi，I think you linked the library libssw.a befor compiling，see The target sequence：

loongson@debian:~/workspace/test/libssw/libssw-1.1/src$ make -n

g++ -fPIC -shared -rdynamic -Wl,-soname,libssw.so.0 -o libssw.so.0 ssw.c ssw.h ssw_cpp.h ssw_cpp.cpp

cc -o ssw-align main.c kseq.h -L. -lssw -lm -lz

cc -c -o ssw.o ssw.c

cc -o example_c ssw.o example.c -lm -lz

g++ -c -o ssw_cpp.o ssw_cpp.cpp

g++ -o example_cpp example.cpp ssw.o ssw_cpp.o -lm -lz

ar rcs libssw.a ssw.o ssw_cpp.o

in line 33 of the ./src/Makefile，Modified like this may be better：

33: $(PROG): main.c kseq.h $(LIB) $(STATICLIB)

The target sequence after ：

loongson@debian:~/workspace/test/libssw/libssw-1.1/src$ make -n
g++   -fPIC -shared -rdynamic -Wl,-soname,libssw.so.0 -o libssw.so.0 ssw.c ssw.h ssw_cpp.h ssw_cpp.cpp 
cc -c -o ssw.o ssw.c  
g++ -c -o ssw_cpp.o ssw_cpp.cpp  
ar rcs libssw.a ssw.o ssw_cpp.o
cc   -o ssw-align main.c kseq.h -L. -lssw -lm -lz 
cc -o example_c ssw.o example.c   -lm -lz 
g++ -o example_cpp example.cpp ssw.o ssw_cpp.o   -lm -lz 

Hoping to help
