链接到库和模块时，创建f2py共享对象文件
我可以通过这些命令正常编译fortran程序：
ifort -O2 -I/work/GSI/include -c create_upperair.f90
ifort -o create_upperair.exe -O2 create_upperair.o -L/work/GSI/lib -lbufr
我试图采用相同的fortran程序，但将其编译为python共享对象文件，以便我可以从python脚本调用此子例程。 但是，f2py命令给我的问题。
这是我目前使用的命令：
f2py -c -L/work/GSI/lib -lbufr -I/work/GSI/include --f90flags=-O2 --fcompiler=ifort -m create_upperair create_upperair.f90
但是，它会在f2py命令的末尾显示类似以下内容的错误：
ld: /work/GSI/lib/libbufr.a(closbf.o): relocation R_X86_64_32S against `nulbfr_' can not be used when making a shared object: recompile with -fPIC
我试图在我的f2py命令中添加--f90flags =“ - O2 -fPIC”，但它也不起作用。 任何有关如何解决这个问题的想法都将非常感谢。
以下是f2py结尾处的完整错误（请注意，为简单起见，我更改了几个目录名称）：
