nco @4.5.2_2: /opt/local/include/antlr/CharScanner.hpp:565:41: error: 'strcasecmp' was not declared in this scope

Description

It appears that the nco build fails due to an issue in the ncoLexer, due to an issue in the antlr port CharScanner.hpp "strcasecmp" routine, if I'm reading the main.log properly.

I believe the issue is shown in this main.log excerpt:

Replying to gryphon.csd8@…:

Almost right: strcasecmp is an operating system function, which for some reason is not being found.

It seems that clang++ can compile ncoLexer.cpp but g++. I was able to compile ncoLexer.cpp by patching CharScanner.hpp. But I still have link errors.

comment:6 Changed 9 years ago by tenomoto (Takeshi Enomoto)

clang++ used to compile antlr and g++ seems to generate different symbols. e.g. for antlr::ASTFactory::create

$ nm work/nco-4.5.5/src/nco++/ncoParser.o | grep ASTFactory | grep create
                 U __ZN5antlr10ASTFactory6createENS_13TokenRefCountINS_5TokenEEE

Resolution: wontfix
Status: newclosed

I simply disabled ncap2 when compiled with gcc in r146325. I added a patch to antlr in r146324. If someone let me know how to fix the symbol problem, I'll enable ncap2 again for gcc.
