howto select the static version of a library with -l (but not for all the other libraries)

[Sid Touati]

Hello everyone,

I have a question that I am unable to solve by myself (and also by 
googling; other computer scientists colleagues fail too).

To give a concrete example, suppose that I have a g++ compiler command 
line  such as :
g++ -O0 -g3  -o sira sira.o RG.o intLPSIRA.o siraloop.o anyoption.o 
-L/home/touati/lib -L/usr/ilog/cplex100/lib/x86_rhel4.0_3.4/static_pic 
-L/home/touati/lp_solve_5.5/lib -L/usr/lib -llpsolve55 -lpthread -lm 
-lcplex -lDDG -lG -lL -lboost_filesystem


And I would like to select the static version of libboost_filesystem. 
That is, I would like to tell to the linker to use 
libboost_filesystem.a as a the library -lboost_filesystem. We have 
experimented two solutions :
- with -static g++ option : this option makes g++ to consider static 
libraries for all other libraries. But we would like to consider it for 
only one library, not all of them.

- by providing libboost_filesystem.a as a direct object file to the line 
command, but this solution would not be portable to all UNIX platforms.

Does someone has a suggestion ?

Yours
Sincerely
Sid
