python扩展lsblib.so由cython和distutils创建，distutil生成的build命令如下：
/gpfs/software/openlava_sqa/3.3.3/etc/../include/lsbatch.h:1681: warning: function declaration isn’t a prototype
gcc -pthread -shared -L/gpfs/DEV/PLT/software/anaconda2-4.0.0/lib -Wl,-rpath=/gpfs/DEV/PLT/software/anaconda2-4.0.0/lib,--no-as-needed build/temp.linux-x86_64-2.7/openlava/lsblib.o /gpfs/software/openlava_sqa/3.3.3/etc/../lib/liblsfint.a /gpfs/software/openlava_sqa/3.3.3/etc/../lib/liblsf.a /gpfs/software/openlava_sqa/3.3.3/etc/../lib/liblsbatch.a -L/gpfs/software/openlava_sqa/3.3.3/etc/../lib -L/gpfs/DEV/PLT/software/anaconda2-4.0.0/lib -llsfint -llsf -llsbatch -lnsl -ltools -lpython2.7 -o build/lib.linux-x86_64-2.7/openlava/lsblib.so -g
请注意，通过lsblib.o + lib * .a和-lXX两次链接四个库，目标模块是 lsblib.so
-llsfint -llsf -llsbatch -lnsl -ltools
build/temp.linux-x86_64-2.7/openlava/lsblib.o /gpfs/software/openlava_sqa/3.3.3/etc/../lib/liblsfint.a /gpfs/software/openlava_sqa/3.3.3/etc/../lib/liblsf.a /gpfs/software/openlava_sqa/3.3.3/etc/../lib/liblsbatch.a
导入模块时：
/gpfs/software/openlava_sqa/3.3.3/lib/ liblsbatch.so.0 ：undefined 符号：mergeResreq
但是，编译后的 lsblib.so 的符号为
000000000009dc9b T mergeResreq
，符号mergeResreq位于liblsfint.a和liblsfinit.so.0.0.1
nm /gpfs/software/openlava_sqa/3.3.3/lib/liblsfint.so.0.0.1 |grep merge
0000000000010017 T mergeResreq
00000000000161d5 t mergeW
nm /gpfs/software/openlava_sqa/3.3.3/lib/liblsfint.a |grep merge
00000000000041ff T mergeResreq
0000000000000581 t mergeW
为什么在导入模块时，它会在错误的lsbatch.so中找到符号？它不使用lsblib.so中的符号，即使我设置了LD_LIBRARY_PATH，它也不会使用lsfint.so .0.0.1
