Linking matlab libraries with source in linux

[sudhansangeetha]

Hi,

I am trying to link matlab libraries with my sourcecode in ubuntu 11.04. compilation is fine but the linking part fails as follows:

/bin/ld:warning: libstdc++.so.5 needed by libmx.so not found;
libut.so:undefined reference to 'cxa_throw at CXXAB1_1.2'
libustdio.so: undefined reference to 'std::ios_base::Init::~Init() at GLIBCPP_3.2

and similar undefined references..

I am using gcc-4.6 compiler and i could see that my system folder has libstdc++.so.6 in /usr/lib folder whereas matlab looks for libstdc++.so.5.

Any ideas will be very helpful.

The 4.6 compiler is so new, that it is not widely available. In any case, your Matlab code needs a revision earlier of libstdc++, so since you are using 4.6, my recommendation is to install 4.5 and use that. You can have multiple versions of gcc and associated libraries installed on a system without problems, although you may need to change your Makefile(s) to use gcc45 instead of the installed gcc (4.6).
