Can't build missing ADA, Flex

Can't build missing ADA, Flex

[Keith Ross (E-Lands)]

Hi,

I know that there are lots of ongoing build issues with insight-6.30.50 
and have been following the patches, but I think my problem is operator 
error.

I'm building insight-weekly-6.30.50.20051114 under gcc-4.0.2 (c, c++ 
only) and cygwin and get
the follow error.  I install flex but where/what's ada. I assume that I 
configured it wrong.

configure --target=arm-elf --prefix=/gnutools/insight-6.3


make[2]: Entering directory `/tmp/build/gdb/gdb'
if [ "/src/insight/gdb/missing flex" ] && /src/insight/gdb/missing flex 
--version >/dev/null 2>&1; then \
    /src/insight/gdb/missing flex -oada-lex.c 
/src/insight/gdb/gdb/ada-lex.l && \
    rm -f ada-lex.c.new && \
    sed -e '/extern.*malloc/d' \
        -e '/extern.*realloc/d' \
        -e '/extern.*free/d' \
        -e '/include.*malloc.h/d' \
        -e 's/\([^x]\)malloc/\1xmalloc/g' \
        -e 's/\([^x]\)realloc/\1xrealloc/g' \
        -e 's/yy_flex_xrealloc/yyxrealloc/g' \
      < ada-lex.c > ada-lex.c.new && \
    rm -f ada-lex.c && \
    mv ada-lex.c.new ada-lex.c; \
elif [ -f ada-lex.c ]; then \
    echo "Warning: ada-lex.c older than ada-lex.l and flex not 
available."; \
else \
    echo "ada-lex.c missing and flex not available."; \
    false; \
fi
ada-lex.c missing and flex not available.

Not really. Well, at least not on linux! O:-)

Looks okay.

I think that ada support in gdb is relatively new. The lex output is 
usually not checked in. The simplest solution is to run your cygwin 
setup and install the flex package.
