Just add a line #define BOOST_LOG_DYN_LINK 1 as the first line of boosttest.cc. Alternatively, you can add -DBOOST_LOG_DYN_LINK to you compilation step (not the linking step, as you posted in the question): g++ -std=c++11 -Wall -pedantic -g -O0 -DBOOST_LOG_DYN_LINK -c boosttest.cc g++ boosttest.o -lpthread -lboost_log -o boosttest
If want compile the file as 32 bits, you can use: ld -m elf_i386 -s -o file file.o
These are typically part of the linker command line, and are either supplied directly in a target action, or more commonly assigned to a make variable that will be expanded to form link command. In that case: -L is the path to the directories containing the libraries. A search path for libraries. -l is the … Read more
It depends a bit on what you want: A) If you want to specify which libraries to link to, you can use find_library to find libs and then use link_directories and target_link_libraries to. Of course, it is often worth the effort to write a good find_package script, which nicely adds “imported” libraries with add_library( YourLib … Read more
This won’t work. From the man page for gcc: This option will not work on Mac OS X unless all libraries (including libgcc.a) have also been compiled with -static. Since neither a static version of libSystem.dylib nor crt0.o are provided, this option is not useful to most people.
Because that’s how the linking algorithm used by GNU linker works (a least when it comes to linking static libraries). The linker is a single pass linker and it does not revisit libraries once they have been seen. A library is a collection (an archive) of object files. When you add a library using the … Read more
Not exactly kosher, but after digging through the source code for GNU ld it looks like you can specify the address of section after it is defined. The following linker script should give you the desired behavior: MEMORY { ram (rwx) : ORIGIN = 0x10000, LENGTH = 0x0002000 } SECTIONS { .bss (NOLOAD) : { … Read more
It is for resolving circular dependences between several libraries (listed between -( and -)). Citing Why does the order in which libraries are linked sometimes cause errors in GCC? or man ld http://linux.die.net/man/1/ld -( archives -) or –start-group archives –end-group The archives should be a list of archive files. They may be either explicit file … Read more
Passing -relocatable or -r to ld will create an object that is suitable as input of ld. $ ld -relocatable a.o b.o -o c.o $ gcc c.o other.o -o executable $ ./executable The generated file is of the same type as the original .o files. $ file a.o a.o: ELF 32-bit LSB relocatable, Intel 80386, … Read more
You must be reading some outdated copies of the manpages (emphasis added): -rpath=dir Add a directory to the runtime library search path. This is used when linking an ELF executable with shared objects. All -rpath arguments are concatenated and passed to the runtime linker, which uses them to locate shared objects at runtime. vs. -L … Read more
