linux - Tracing linked libraries -


I'm getting some errors which I think my Linux program is connecting to libraries that it's going to do. How do I get the full path for all linked libraries? I know ldd will name me, but how can I use it to get the full path?

Thank you.

Actually ldd whatever you want with the shared library dependency of your application Finding it gives full path with file name. 

  $ ldd v8test linux-gate.so.1 = & gt; (0xb78b2000) libz.so.1 = & gt; /usr/lib/libz.so.1 (0xb787e000) librt.so.1 = & gt; /lib/i686/cmov/librt.so.1 (0xb7875000) libcppunit-1.12.so.1 = & gt; /usr/lib/libcppunit-1.12.so.1 (0xb782c000) libstdc ++ So.6 = & gt; /usr/lib/libstdc++.so.6 (0xb7604000) libm.so.6 = & gt; /lib/i686/cmov/libm.so.6 (0xb75dd000) libgcc_s.so.1 = & gt; /lib/libgcc_s.so.1 (0xb75bf000) libc.so.6 = & gt; /lib/i686/cmov/libc.so.6 (0xb7478000) libpthread.so.0 = & gt; /lib/i686/cmov/libpthread.so.0 (0xb745f000) libboost_system-mt.so.1.38.0 = & gt; /usr/lib/libboost_system-mt.so.1.38.0 (0xb745b000) /lib/ld-linux.so.2 (0xb78b3000) libdl.so.2 = & gt; /lib/i686/cmov/libdl.so.2 (0xb7456000) libboost_thread-mt.so.1.38.0 = & gt; /usr/lib/libboost_thread-mt.so.1.38.0 (0xb7383000) libboost_filesystem-mt.so.1.38.0 = & gt; /usr/lib/libboost_filesystem-mt.so.1.38.0 (0xb7370000) libtinyxml.so.1 = & gt; /home/dmitry/tinyxml/libtinyxml.so.1 (0xb7359000) libboost_regex-mt.so.1.38.0 = & gt; /usr/lib/libboost_regex-mt.so.1.38.0 (0xb728c000) libmysqlclient_r.so.15 = & gt; /usr/lib/libmysqlclient_r.so.15 (0xb70a1000) libicuuc.so.42 = & gt; /usr/lib/libicuuc.so.42 (0xb6f61000) libicudata.so.42 = & gt; /usr/lib/libicudata.so.42 (0xb601a000) libicui18n.so.42 = & gt; /usr/lib/libicui18n.so.42 (0xb5e6b000) libcrypt.so.1 = & gt; /lib/i686/cmov/libcrypt.so.1 (0xb5e39000) libnsl.so.1 = & gt; / Lib / i686 / cmov / libnsl.so.1 (0xb5e22000)

The libraries have its sonum (such as Libobf_FileSystemMTo.1.38.0) code> / etc / ld. So.conf is set in binary by , LD_LIBRARY_PATH or rpath .

If Ldd is unable to find something that will be visible to it 

  libicuuc.so.42 = & gt; Not found

In this case, consider using a method to give the correct search path.

ldd to load the library due to some reason 

  $ ldd v8test ./v8test: error while loading the shared library: / home / Dmitry / a / liba.so.2: Invalid ELF header

Of course it can not protect you from errors in the library. In fact it is possible to rely on your Library A and B For both, on the basis of incompatible versions on some Library C. In this situation, your program has a good chance of accident (unless the library is C) - LDD is not going to warn you, but you should be able to see it in the output.

It will be useful to you. Also check on some options of

ldd or

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....

wpf - Custom Message Box Advice -

Well, I'm using a custom window box that comes with some custom control boxes that accompany the text The producers who are displayed are called. I have a defined event, which has been subscribed through the original class, it gets burnt when clicking on the button. However, I can not see how to use it effectively, I would like to return one yes, whether yes or not, but obviously my code will continue to execute, so this Below is some example code to clarify the problem that the method has subscibed by clicking on the button.
