这是我的bindings.gyp文件:
{
"targets": [
{
"target_name": "hello",
"sources": [ "hello.cpp" ],
"include_dirs": [
"<!(node -e \"require('nan')\")"
],
"cflags" : [ "-std=c++1", "-stdlib=libc++" ],
"conditions": [
[ "OS!='win'", {
"cflags+": [ "-std=c++11" ],
"cflags_c+": [ "-std=c++11" ],
"cflags_cc+": [ "-std=c++11" ],
}],
[ "OS=='mac'", {
"xcode_settings": {
"OTHER_CPLUSPLUSFLAGS" : [ "-std=c++11", "-stdlib=libc++" ],
"OTHER_LDFLAGS": [ "-stdlib=libc++" ],
"MACOSX_DEPLOYMENT_TARGET": "10.7"
},
}],
],
}
]
}
运行时
sudo node-gyp rebuild
我收到这些错误:
make: Entering directory '/home/oleg/WebstormProjects/oresoftware/replace-line/build'
CXX(target) Release/obj.target/hello/hello.o
g++: error: unrecognized command line option ‘-std=c++1’
g++: error: unrecognized command line option ‘-stdlib=libc++’
hello.target.mk:106: recipe for target 'Release/obj.target/hello/hello.o' failed
从错误跟踪中,似乎很清楚我们使用的是g ++而不是gcc,而我的g ++版本是:
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)
,是的,我在Ubuntu 16.04
有谁知道为什么会出现这个错误?
答案 0 :(得分:1)
您有-std=c++1
,这是一个错字,它应该是:-std=c++11
。
此外,-stdlib
是一个clang选项(不是g ++)。对于g ++,总是使用libstdc ++。
