re: compling from CVS: lex.l errors

[Richard Hindmarsh]

I ran into the same problem as below - I didn't entirely follow the 
ensuing conversation, but I fixed it by

(i) updating my Cygwin "gperf" to 3.0.1. This cannot be done from Cygwin 
it seems (latest version is 2.7.2), so I had to download and make 
source. I deduce from looking at configure that versions of gperf prior 
to 3.0.1 are deprecated, but this either didn't appear or got lost in 
the "configure" output.
(ii) I had an empty oct-gperf.h left over from previous attempted makes, 
which I had to explicitly delete.

I'm trying to compile a clean checkout of the sparse-merge branch.
I'm getting the following error:

   $ ./autogen.sh
   $ ./configure --enable-shared --enable-dl --disable-static
   $ make
    ...
   g++ -c  -fPIC -I. -I.. -I../liboctave -I../src -I../libcruft/misc  -I../glob 
-I../glob -DHAVE_CONFIG_H -mieee-fp -Wall -W -Wshadow -g -O2 lex.cc -o pic/lex.o
   lex.l: In function `int is_keyword_token(const std::string&)':
   lex.l:1004: error: expected primary-expression before "const"
   lex.l:1004: error: expected `;' before "const"
   lex.l:1006: error: `kw' undeclared (first use this function)
   lex.l:1006: error: (Each undeclared identifier is reported only once for 
each function it appears in.)
    ... and lots more errors

I'm using the latest versions of g++ (3.3.5 and 3.4.4) and flex 2.5.31.
This fails under Debian and cygwin. David Bateman suggested gperf may
be an issue, but I seem to have the latest version.

Could anyone help?
