RE: [Gretl-users] Using the libgretl shared library in C++

I don't see any "-L" reference on your link line for the "libgrtl-1.0.so", just the fact you want to link to it, "-l". It appears you're building on a unix platform.. does gretl supply a precompiled binary that runs on a unix platform, as well... and if so, can it be invoked to read a text file.. I note that in a Windows environment it has this type of run state, as defined in the documentation. -----Original Message----- From: gretl-users-bounces(a)lists.wfu.edu [mailto:gretl-users-bounces@lists.wfu.edu] On Behalf Of Ganguly, Sunandan Sent: Thursday, April 30, 2009 3:25 PM To: Gretl list Subject: RE: [Gretl-users] Using the libgretl shared library in C++ Sorry, I forgot to mention my platform - Linux SLES10 64 bit AMD x86-64 Sunandan Ganguly CREDIT SUISSE Direct: (212) 325-0673 e-mail: sunandan.ganguly(a)credit-suisse.com Please follow the attached hyperlink to an important disclosure: http://www.credit-suisse.com/legal/marketcommentary -----Original Message----- From: gretl-users-bounces(a)lists.wfu.edu [mailto:gretl-users-bounces@lists.wfu.edu] On Behalf Of Ganguly, Sunandan Sent: Thursday, April 30, 2009 3:11 PM To: Gretl list Subject: [Gretl-users] Using the libgretl shared library in C++ Hi, Has anyone out there ever tried to use the api-s within the shared library from inside a C++ program? If yes, I'd like to hear about your experience with compiling and linking your program. I have spent the last two days trying to build an app where I want to use some basic regression, but I cant even get past the build stage. I get this linker error : /app/devtools/gcc-4.3.3/bin/g++ -m64 -mtune=opteron -lpthread Main.o -L/app/devtools/gretl-1.8.0.org/lib -lgretl-1.0 -L/app/devtools/zlib-1.2.3/lib -lz -L/app/devtools/libxml2-2.7.3/lib -lxml2 -L/app/devtools/glib-2.14.6/lib -lglib-2.0 -L/app/devtools/refblas3-3.0-11/lib64/libblas.so.3.0.0 -L/app/devtools/liblapack3-3.2.0-5/lib64/liblapack.so.3 -L/app/devtools/fftw-3.2.1/lib -lfftw3 -L/app/devtools/gcc-4.3.3/lib64/libgfortran.so.1 -o Application.x /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgecon_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dsytri_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgetrs_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dorgqr_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dpocon_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dtrcon_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgeqrf_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgesvd_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dtrtri_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dsyev_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dsycon_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgels_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgelss_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dpptrf_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgemm_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgetri_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dpotrf_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dspsv_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dsyrk_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgetrf_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dpotrs_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dpotri_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dpptri_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dsytrf_' /app/devtools/gretl-1.8.0.org/lib/libgretl-1.0.so: undefined reference to `dgeev_' collect2: ld returned 1 exit status make[1]: *** [Application.x] Error 1 make[1]: Leaving directory `/app/home/sganguly/dev/atlas-HEAD-64/atlas/src/Application' make: *** [All] Error 2 Note that the actual gretl shared lib was built succesfully. I get these errors in my app from which I am trying to use the gretl lib. Any insights/pointers anyone? PS: I have a suggestion as well - I think its best to avoid using C++ keywords such as "new" and "template" inside the C code for gretl as this also causes trouble to folks that are trying to use the shared lib from C++.
