[Moose-g3-devel] Compilation issues with flex on Ubuntu Dapper

[Upinder S. B. <bh...@nc...>]

Dear all,
  I've shifted to Ubuntu Dapper and moose compilation issues arise becaus=
e
it seems that flex and other tools have been upgraded. Suggestions for
cleaner fixes would be nice.

- flex-old does not work: seems like enough other things have also change=
d.
- I can eliminate most warnings using a few extra compiler flags
- I can get the whole thing to compile and run by manually editing the
generated parser code. This is obviously not a clean way to do things, bu=
t
it shows that the errors are pretty minor provided one can persuade Flex
to behave.

- Here are the compiler flags that eliminate most errors:
             -DYYMALLOC -DYYFREE

- Here are the remaining error messages:

/usr/include/FlexLexer.h:113: error: redefinition of =91class yyFlexLexer=
=92
/usr/include/FlexLexer.h:113: error: previous definition of =91class
yyFlexLexer=92
GenesisParser.yy.cpp:1850: error: declaration of =91int isatty(int)=92 th=
rows
different exceptions
/usr/include/unistd.h:717: error: than previous declaration =91int
isatty(int) throw ()=92
GenesisParser.tab.cpp: In member function =91int myFlexLexer::yyparse()=92=
:
GenesisParser.tab.cpp:2756: error: =911=92 cannot be used as a function
make[1]: *** [GenesisParser.tab.o] Error 1

The first error (line 113) is fixed if we comment out this line:

GenesisParser.yy.cpp:20
    #define yyFlexLexer yyFlexLexer

(yes, it seems like an incredibly dumb line)


The second error (1850) goes away if we comment out the declaration
The third error (2756) I don't recall the cure for, but I think it was to
eliminate the offending line.

By the way, Joe mentioned that he had MOOSE compiled on Windows. We shoul=
d
look at merging the branches with the main development line.

Thanks,
  Upi
