Programming :: Specify A Library Search Path To Configure's AC_CHECK_LIB?
Aug 31, 2010I'm writing an application and want to make possible to compile it with or without an optional module. This module requires perl library to be compiled, so I want to check presence of it in 'autoconf'.
The problem exists because perl library is placed in 'non-standart' location itself (like a /usr/lib64/perl5/CORE/libperl.so). So when I try to run configure (with AC_CHECK_LIB or AC_SEARCH_LIBS), it cannot find and link libperl.so in its test.
Trying to pass ./configure CFLAGS=-L/usr/lib64/perl5/CORE/ or ./configure LDFLAGS=-L/usr/lib64/perl5/CORE/
How can I define a location to search for configure's tests?
Programming :: How To Change - Add To - Library Search Path At Runtime
Jan 9, 2011I'm writing an application with a plugin architecture and would like modify (specifically add to) the dynamic library search path while the main executable is running.
The plugin paths are not known until the application is running so I can't set LD_LIBRARY_PATH ahead of time.
My understanding (although I haven't tested it) is that the executable will only parse the LD_LIBRARY_PATH once, early on, so modifying this environment variable at runtime will have no effect.
(Note - on Windows the solution is to modify the PATH environment variable)
I know it's possible to specify the full path to load a dynamic library, and this would work if the plugin(s) only had a single library to load, but some of them will have a bunch of libraries with their own inter-dependencies, so I'd like the plugin folder(s) to get added to the search path to pick up the dependant libs.

Programming :: C++ Invalid Conversion From Const Char* To Char*
Jul 9, 2010I am having trouble with the following exception class.
Code:
/**Standard Exception
*
*@description
*@update
*@changes
[code]....
Line 43 points at the snprintf() command.I think the error has to do with the function being virtual and the const after the function definition, however although I have been looking really hard I have not being able to find the reason nor the solution to the problem.
One workaround that I know is moving the block of source withing the virtual function, in the constructor, however having read around (boost library exceptions tutorials) it specifically said that formating of errors messages should not take place withing the construction of objects because we are risking throwing an exceptions and messing up the flow order.

Fedora :: Search Path - Yum & Rpm Commands Fail When Executed As Root

Software :: Custom Built GCC - Default Search Path For Stdlib
Jun 15, 2011I've just built gcc 4.6.0 by myself since there is no update in Mandriva yet and I really needed the updated version, but I must be missing something in its configuration. I added ~/apps/gcc460/bin in front of my PATH, and the lib dir to my LD_LIBRARY_PATH in my .bash_profile, like so:
Code:
PATH=$HOME/apps/gcc460/bin:$PATH:$HOME/apps/bin
LD_LIBRARY_PATH=/home/duckz/apps/intel/composerxe-2011.4.191/lib/intel64/:/home/duckz/apps/gcc460/lib/
LD_RUN_PATH=/home/duckz/apps/intel/composerxe-2011.4.191/lib/intel64/:/home/duckz/apps/gcc460/lib/
export PATH
export LD_LIBRARY_PATH
export LD_RUN_PATH
I still have gcc 4.4.2 installed, but it's now hidden, so gcc --version correctly yields 4.6.0. I finally tried to build my project, all went fine, but at the moment of running it I get:
Code:
./EugGame.Release.Linux: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by ./EugGame.Release.Linux)
I assume the correct version is the one located in ~/apps/gcc460/lib, but how do I make my project load the correct lib? Is it possible at all to have two versions of gcc on the same machine? I just found that I should've added lib64 to my LD_LIBRARY_PATH instead of lib. Anyways, even if the problem is solved, I'd like to hear if my configuration is well made or if I should leave LD_LIBRARY_PATH unset and use some other way to override the default search path for stdlib.

View 6 Replies View RelatedProgramming :: GMP And Converting Mpz_t To Char?
Jul 16, 2011I'm writing the Diffie-Hellman key exchange system using GMP to handle big integers. For the most part, everything works. I can convert the string to mpz_t, set up the keys and everything, and encrypt it fine. Its the decrypting I'm having issues with. What I'm using is mpz_xor() for both. To encrypt I'm doing mpz_xor(buffer, mpz_of_text, secret_key), and to decrypt I'm doing mpz_xor(buffer, mpz_of_cipher, secret_key).
For one character, it semi-works...it'll decrypt it fine, but it'll return it as it's ASCII value (i.e.: if I encrypt "A", it'll decrypt it as 65). Which, I can easily just do sprintf(decrypted_buffer, "%c", 65) for example and be fine. But, when I'm sending text bigger than one character, the encryption for AB gives me something like 1061043 after running the decrypting xor on it.
Has anyone ever done this before or can point me in some directions? Perhaps other algorithms to try? I know XOR isn't the most secure encryption method to use, but at the time I wasn't sure what else to use. I'm really just having a hard time trying to convert a mpz_t to a character string. I've looked at mpz_get_str() and it works before running encryption (i.e.: using mpz_set_str() to create a mpz of a string, then calling mpz_get_str() to change it back). Maybe my XOR method is wrong? Here's the code I'm using:
Code:
/**
* str2mpz()
* b The current buffer of text to convert [in]
* m The mpz_t variable to store converted text [out]
