Question

我正在尝试编译一个我用ANTLR创建的简单语法，但我不断收到链接错误。最后我想在一个C ++项目中包含ANTLR语法，但是现在如果在C语言中进行编译和链接，我会很高兴。我第一次尝试：

g++ -oX -I/usr/local/include -I../src -L/usr/local/lib -lantlr3c \
../src/RtfLexer.cpp \
../src/RtfParser.cpp

然后我尝试了：

gcc -oX -lantlr3c -I../src ../src/RtfLexer.cpp ../src/RtfParser.cpp

但我一直在接受：

/tmp/ccJgJxMH.o: In function `RtfLexerNewSSD':
RtfLexer.cpp:(.text+0xb0): undefined reference to `antlr3LexerNewStream'
/tmp/ccVZ2Vco.o: In function `RtfParserNewSSD':
RtfParser.cpp:(.text+0x7d): undefined reference to `antlr3ParserNewStream'
RtfParser.cpp:(.text+0xfa): undefined reference to `ANTLR3_TREE_ADAPTORNew'
RtfParser.cpp:(.text+0x10e): undefined reference to `antlr3VectorFactoryNew'
/tmp/ccVZ2Vco.o: In function `plaintext(RtfParser_Ctx_struct*)':
RtfParser.cpp:(.text+0x8c4): undefined reference to `antlr3RewriteRuleTOKENStreamNewAE'
RtfParser.cpp:(.text+0x992): undefined reference to `antlr3RewriteRuleTOKENStreamNewAE'
RtfParser.cpp:(.text+0xa60): undefined reference to `antlr3RewriteRuleTOKENStreamNewAE'
RtfParser.cpp:(.text+0xb2e): undefined reference to `antlr3RewriteRuleTOKENStreamNewAE'
RtfParser.cpp:(.text+0xbfc): undefined reference to `antlr3RewriteRuleTOKENStreamNewAE'
[more to follow]

所以似乎无法找到库，但g ++和gcc不会抱怨。我重新安装了库，重新生成了语法，到目前为止没有运气。我错过了一些明显的东西吗？提前谢谢！

将库放在编译器命令的末尾：

g++ -oX -I../src ../src/RtfLexer.cpp ../src/RtfParser.cpp -lantlr3c

ANTLR语法链接错误
