在Ubuntu机器上构建htdig

Question

On my Ubuntu machine, htdig (www.htdig.org) is installed. eg "which htdig" gives me, /usr/bin/htdig

I want to install htdig under /var/www/my_web_site ie /var/www/my_web_site/htdig

Extra info:

• gcc version 4.9.1 (Ubuntu 4.9.1-16ubuntu6)
• GNU Make 4.0

For htdig-3.1.6:

When I run "./configure", I got:

configure: error: To compile ht://Dig, you will need a C++ library. Try installing libstdc++

"Run /sbin/ldconfig -p | grep stdc++"

I have:

• libstdc++.so.6 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
• libstdc++.so.6 (libc6) => /usr/lib/i386-linux-gnu/libstdc++.so.6

---

I also tried out htdig-3.2.0b6 :

I run "./configure", and it seems fine. I got something like "Now you must run 'make' followed by 'make install'"

When I run "make", I got quite a few errors like:

.....

     if (input->exists("endyear"))
                                ^

Any idea what I should do?

Answer 1

The compiler is complaining that the class prefix Collection:: in Collection.h is both unnecessary, and now, illegal.

Simply change the htsearch/Collection.h header to this:

class Collection : public Object
{
public:
    //
    // Construction/Destruction
    //
    Collection(const char *name, const char *wordFile,
               const char *indexFile, const char *docFile,
               const char *docExcerpt);
    ~Collection();

    // COMMENT OUT OR REMOVE THESE TWO LINES:
    //    void Collection::Open();
    //    void Collection::Close();
    // ADD THESE TWO:
    void Open();
    void Close();

(comment out/remove old lines declaring Open/Close and add the last two lines above)

After doing this, htdig 3.2 b 6 compiled successfully for me. The warnings are just that: warnings. They won't prevent successful compilation. This is now a very old codebase, and some of the C++ is invariably not compliant with current compiler standards.
