[Boost-users] Re: Problems using boost-regex after being compiled as non root.

Actually I tried generating the object file which is possible:

c++ -I$PATH1/include/boost-1_32 -L$PATH1/lib -c credit_card_example.cpp

This provides me with credit_card_example.o.  Then when it comes to the
linking stage all the whole bunch of error messages show up:

c++ -I$PATH1/include/boost-1_32 -L$PATH1/lib credit_card_example.o -o
trial

Then someone in the list indicated I at least needed to indicate I want
to link regex library, and "-l" was indicated for that purpose:

c++ -I$PATH1/include/boost-1_32 -L$PATH1/lib -llibboost_regex-gcc
credit_card_example.o -o memo

I'm not sure why this is necessary, but it works, but it links using
the dynamic library, something I surely do NOT want (I want a
statically linked executable with no dependancies).  So then I tried
-static:

c++ -I$PATH1/include/boost-1_32 -L$PATH1/lib -static -lboost_regex-gcc
credit_card_example.o -o memo

And I got a whole bunch of error messages again:

       1 credit_card_example.o: In function

std::allocator<char> >::bas

      59 rge]()'
      60 collect2: ld returned 1 exit status

When I read the documentation for "-l" I found "The linker
searches a standard list of directories for the library,
which is actually a file named liblibrary.a. The linker
then uses this file as if it had been specified precisely by name.",
so I'm confused why the dynamic library is being used...  Any ways, I
used -static, and it didn't work when it should ("On systems that
support dynamic linking, this prevents linking with the shared
libraries").

1st thing is indications on what I need to be able to get a static
linkage, and 2nd maybe a clarification about specifying the boost
libraries...

Besides this static/dynamic problem, I'm wondering why I need to
specify the boost libraries to use (that's not required for std
libraries at all).  If one requires several boost libraries, then are
all them to be specified as well?

Please include my e-mail in your replies, so I can soon and easily get
them...


Thanks a lot,

Javier.
