2008年9月5日 · Each component can be treated as one library - if any one library from the component is needed, the dependency cycle(s) will cause all libraries in that component to be needed. So no, there really is no need to cycle through all the libraries in order to resolve everything, and no need for awkward command-line options - one method using two well-known algorithms can handle all cases correctly.
But this is not talking with gcc driver, but with ld linker as options like -Wl,anything are. When you tell gcc or ld -Ldir -lLIBRARY, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose). To change order of library .
2015年7月16日 · The -l options specifying library names should appear after the object file names. The -L options, which specify a library directory, should appear before the -l options for libraries that are stored in the directory.
2010年4月29日 · To conclude: The static library under Linux is nothing more than an archive of object files. fun1(10); fun2(10); return 0; printf("%i\n",x); extern “C” {. printf("%i\n",2*x); extern “C” {. it would have helped to point out what the commands do, and what they intend to achieve. especially in this case the ar needs explanation, as it is ...
2017年5月30日 · I have a shared library (*.so) created using Real View Compiler Tools (RVCT 3.2) on windows target. Then I try to link this *.so file with my application using gcc on linux system. What is the gcc
2012年7月25日 · I believe that there are three arguments that you will need to set: -I <include directory>. -L <library directory>. -l <library name>. The include directory will be location of the header files. The library directory will be the location of the library (.a or .so), and the library name will be the name of the library file, without the leading ...
2019年10月29日 · In order to figure out the default paths used by gcc / g++, as well as their priorities, you need to examine the output of the following commands: For C: echo | gcc -xc -E -v -. For C++: echo | gcc -xc++ -E -v -. The credit goes to Qt Creator team. Here's a breakdown of the flags: -x selects the language, C or C++ respectively.
2011年5月8日 · If you are on RPM based Linux (Red Hat/CentOS/Fedora/SUSE) then you would get the location of the installed glibc with rpm -ql glibc and rpm -ql glibc-devel . locate libc.a would get you the location. And to see from where it comes do: rpm -qf /usr/lib/libc.a. Here is what rpm -qi has to tell about these packages.
420. To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag. gcc -c -fPIC hello.c -o hello.o. This will generate an object file (.o), now you take it and create the .so file: gcc hello.o -shared -o libhello.so. EDIT: Suggestions from the comments: You can use.
LIBRARY_PATH is used by gccbefore compilation to search directories containing static and shared libraries that need to be linked to your program. LD_LIBRARY_PATH is used by your program to search directories containing shared libraries after it has been successfully compiled and linked. EDIT: As pointed below, your libraries can be static or ...
