Hi
I was trying to build a static version of the regex library (boost 1.39), issuing this command:
./bjam --build-dir=build_static --layout=system threading=single runtime-link=static link=static
but I always get this error:
error: link=shared together with runtime-link=static is not allowed error: such property combination is either impossible error: or too dangerious to be of any use
but why is it trying to use link=shared when I explicitly specified link=static?
You must have an ICU installed, and Boost.Regex tries to use that automatically. ICU only comes as shared library. You might wish to remove the ICU_PATH setting in project-config.jam or whenever it's is made.
Hi
I removed the ICU reference from the project-config.jam, and managed to build the library; however when I statically link to boost regex library, I get
libtool: link: g++ -g -O2 -static -o check-regexp check-regexp_cmd.o check-regexp.o -L/opt/boost/lib -lboost_regex-gcc43-mt-1_39 ../gl/.libs/libgnu.a /opt/boost/lib/libboost_regex-gcc43-mt-1_39.a(static_mutex.o): In function `boost::scoped_static_mutex_lock::unlock()': static_mutex.cpp:(.text+0x16): undefined reference to `pthread_mutex_unlock' /opt/boost/lib/libboost_regex-gcc43-mt-1_39.a(static_mutex.o): In function `boost::scoped_static_mutex_lock::lock()':
thus the library was not linked with runtime-link=static, was it?
I don't think this conclusion is right -- nothing above suggests any dependency on any shared library. Rather, the errors above mean that you have: 1. Failed to linked with boost.thread library 2. Failed to pass -pthreads to the compiler
Or at least, it builds a multi-threaded version while I requested, with threading=single a single threaded version...
To begin with, you are requesting multithreaded library: -lboost_regex-gcc43-mt-1_39 Here, "mt" stands for multithreaded. Then, it's is fairly unlikely that such a library would be produced if you say threading=single. I would guess that -L/opt/boost/lib has something you previously installed, and if you run: ./bjam --build-dir=build_static --layout=system threading=single runtime-link=static link=static it puts new libraries in stage/lib. Did you copy non-MT versions to /opt/boost/lib? If so, you should be using -l option without "mt".
I actually need to build a static version of boost which does not depend on any other dynamic library (because, in turn, I need to build a completely static binary that uses boost)... where am I going wrong?
Hopefully the above explains this? - Volodya
