Hello Brad,

I am trying to make a package called visual python, but I keep getting this error. I am using fedora 8 and have

Linking cvisualmodule.la ... make[1]: *** [cvisualmodule.la] Error 1 make[1]: Leaving directory `/home/brad/Download/visual-4.beta16/src' make: *** [all-recursive] Error 1

The key reason I get this error is this line right here... /usr/bin/ld: cannot find -lboost_thread

I looked online saw that I could try --LDFLAGS-L[path], where path is the path to libboost_thread.so and libboost_thread.a. Those files don't exist on my computer and I have boost-1.34.1-5.fc8 and boost-devel-1.34.1-5.fc8. I did however find /usr/lib/libboost_thread-mt.so, /usr/lib/libboost_thread-mt.so.1.34.1, and /usr/lib/ libboost_thread-mt.so.3.

As far as I know (someone correct me if I'm wrong) boost_threads always comes in a `-mt' flavor (I think it's obvious why) so you must use -lboost_thread-mt instead.

I did not make the config file for this but I need to install it. Is there some kind of argument I can pass during configure to fix this?

I don't understand what you mean, which configure are you talking about? The configure of Boost itself or that of the project you're trying build? For Boost, just do a standard install, but since you already have the file /usr/lib/libboost_thread-mt.so, you don't need to worry about that. For the project you're trying to build, if it uses the autotools (that is, its configure script has been generated by autoconf) use ./configure LIBS=-lboost_thread-mt Otherwise, if none of this works, you'll just have to hack the build system of that project so that it uses -lboost_thread-mt where needed. -- Benoit Sigoure aka Tsuna EPITA Research and Development Laboratory

You must check that the required argument is specified: if( !varmap.count("a") ) { cerr << "Argument 'a' missing!" << endl; return 1; } /Mikko swapna wrote:

How to include all options as mandatory ones. ex: test.exe -a "address" -b "BW" Both -a and -b should be specified.It is manadatory How to make it mandatory using program_options in boost.
