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

[almage (Roy Miller)]

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.

[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

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.
