Thanks Raul, Nat, and Roland,
I appreciate the help.
I finally found my way here:
http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Link-Options.html#Link-Options
It seems these are key for static linking:
-static -static-libgcc
I am not used to the gcc compiler and it seems like it
does dynamic linking by default. Is that correct? I
thought that -l specified static linking (it seems I
was wrong)
...and are currently using these options for compiling
and linking:
Compile:
g++ -I/home/quirk/dev/lib/boost_1_33_1/ -O0 -g3 -Wall
-c -fmessage-length=0 -pthread -MMD -MP -MF"main.d"
-MT"main.d" -o"main.o" "../main.cpp"
Finished building: ../main.cpp
Link:
g++ -L/home/quirk/dev/lib/boost_1_33_1/stage/lib
-static -static-libgcc -o"ManagedMakeProject"
./main.o -lboost_thread-gcc-mt-d-1_33_1 -lpthread

Thanks for the reply.
When I change the linker line to this (added the .a extension): g++
-L/home/fejimush/development/libraries/boost_1_33_1/stage/lib
-o"ManagedMakeProject" ./main.o -lboost_thread-gcc-mt-d-1_33_1.a
I get the follow error:
/usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../../../i686-pc-linux-gnu/bin/ld:
cannot find -lboost_thread-gcc-mt-d-1_33_1.a
The file is there and everything seems to be spelled correctly, path and filename.
If you want that the linker doesn't search the library, you dont have to use the -l flag. Try linking with this:
g++ \ -o"ManagedMakeProject" ./main.o \
/home/fejimush/development/libraries/boost_1_33_1/stage/lib/libboost_thread-gcc-mt-d-1_33_1.a
(Assuming that the file libboost_thread-gcc-mt-d-1_33_1.a is in the directory
/home/fejimush/development/libraries/boost_1_33_1/stage/lib)
The -l flag searches first for the dinamic (.so) library, and only if it can't find it, it searches for the static version.
But, returning to your first post, I think that your problem doesn't happens at build time, does it? When do you get the message "error while loading shared libraries"? At link time or at run time?
If you are sure that the file
/home/quirk/dev/libraries/boost_1_33_1/stage/lib/libboost_thread-gcc-mt-d-1_33_1.so
exists and that the problem is at run time, then try this:
g++ -L/home/quirk/dev/libraries/boost_1_33_1/stage/lib \ -o"ManagedMakeProject" ./main.o -lpthread \ -lboost_thread-gcc-mt-d-1_33_1 \
-Wl,-rpath,/home/quirk/dev/libraries/boost_1_33_1/stage/lib
Regards, Raul.
