【问题描述】：

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

输出是

/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指令的文件是cmathcomplex.hcstdlibstdlib.htgmath.htgmath.hfenv.hmath.hbits/std_abs.h

你推荐什么解决方案来解决这个问题？

【参考方案1】：

删除-includeall。这试图为每个包含的头文件中的每个函数递归地制作 swig 包装器。您通常只需要自定义 API 标头中的函数。
