我正在尝试使用Swig为用C ++编写的库生成python绑定。
当我在Debian GNU / Linux 10上运行时
swig -I/usr/include \
-I/usr/include/c++/8 \
-I/usr/include/c++/8/tr1 \
-I/usr/include/linux \
-I/usr/include/x86_64-linux-gnu \
-I/usr/include/x86_64-linux-gnu/c++/8 \
-I/usr/share/swig3.0/python \
-I$(KALDI_ROOT)/tools/openfst/src/include \
-I$(KALDI_ROOT)/src \
-includeall -c++ -python ConstArpaLmRescoring.i
输出为
/usr/include/c++/8/cstdlib:75: Error: Unknown SWIG preprocessor directive: include_next (if this is a block of target language code, delimit it with %{ and %})
/usr/include/c++/8/bits/std_abs.h:38: Error: Unknown SWIG preprocessor directive: include_next (if this is a block of target language code, delimit it with %{ and %})
/usr/include/c++/8/bits/c++0x_warning.h:32: Error: CPP #error "This file requires compiler and library support \
for the ISO C++ 2011 standard. This support must be enabled \
with the -std=c++11 or -std=gnu++11 compiler options.". Use the -cpperraswarn option to continue swig processing.
/usr/include/c++/8/cmath:45: Error: Unknown SWIG preprocessor directive: include_next (if this is a block of target language code, delimit it with %{ and %})
make: *** [Makefile:38: all] Error 1
包含include_next
指令的文件为cmath
complex.h
cstdlib
stdlib.h
tgmath.h
fenv.h
math.h

您建议使用哪种解决方案来解决此问题?
答案 0 :(得分:2)
删除-includeall
。这样做试图递归地为每个头文件中的每个函数制作Swig包装器。通常,您只需要自定义API标头中的功能。
