UDF and GNU Scientific Library

Hi guys,

I have been working with acuSolve user-defined function (UDF) for a while. To utilize the computational capacity of C-programming language, I plan to use GNU Scientific Library (which is a popular library to use with C) in my UDF.

Currenly, I am using a linux machine. I have successfully added path to the library in my .bashrc file and have sourced it properly. During gcc compilation, I am giving appropriate flags so that the libraries are linked properly during compilation. I have successfully compiled the UDF--there's no error during the compilation and I am able to obtain a libusr.so file.

The problem is during running "acuRun -libs libusr.so" command, I get an error during execution of acuSolve. I checked at the log file which has the following error information.

/home/.../altair/hwcfdsolvers/acusolve/linux64/bin/acuSolve-impi: symbol lookup error: libusr.so: undefined symbol: gsl_vector_alloc

BTW, gsl_vector_alloc is a command available in GNU Scientific Library. What should I do to rectify the error?

Thanks in advance.
