SWIG不支持include_next GNU指令

Question

我正在尝试使用Swig为以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cmathcomplex.hcstdlibstdlib.htgmath.hfenv.hmath.h bits/std_abs.h

您建议使用什么解决方案来解决此问题？

删除-includeall。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。
