我能够使用这些命令正常编译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
我正在尝试使用相同的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命令给了我一些问题。
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，在f2py命令的末尾打印出错误，如：
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
我试图添加--f90flags =＆＃34; -O2 -fPIC＆＃34;我的f2py命令，但它也没有工作。任何有关这个问题的方向的想法都将非常感激。
这是f2py结束时的完整错误（请注意，为简单起见，我在上面更改了一些目录名称）：
