Hello,
I'm trying to compile a test program from one of the libgretl examples on 64bit Linux
Mint 17.3. My goal is to call gretl routines from C.
I think configure went ok (linked it to lapack: sudo LAPACK_LIBS=/usr/lib/liblapack.a
./configure). Then make, make install and sudo ldconfig.
I run the following command (and other countless variations) to compile:gcc -o gretl_test
-L/usr/local/lib/libgretl-1.0.so `pkg-config --cflags --libs glib-2.0` gretl_test.c
However, I get the following errors:/tmp/ccCyYTcx.o: In function
`main':gretl_test.c:(.text+0x22): undefined reference to
`libgretl_init'gretl_test.c:(.text+0x31): undefined reference to

`gretl_print_destroy'gretl_test.c:(.text+0xf5): undefined reference to
`libgretl_cleanup'
I'm a relatively new convert to linux as well as gretl, is there something obvious
that I'm missing?
Thank you.

To ensure the correct libraries are linked in, you should use
gretl's pkgconfig file. There's an example Makefile in the "extra"
subdir of the gretl sources. Abstracting a little from the
specifics there, at minimum you need:
CFLAGS = $(shell pkg-config --cflags gretl)
LDFLAGS = $(shell pkg-config --libs gretl)

Hmmm... I cd'ed into the extras folder and tried compiling the three examples there
with the default makefile.I still get errors:

Does /usr/local/lib/libgretl-1.0.so actually exist, and point to an
valid library file such as libgretl-1.0.so.16.0.0?
If not, the installation was not successful; but if so, you might
need to tell the linker to update its cache:
sudo ldconfig
and/or if /usr/local/lib is not a directory known to the linker you
may have to add an entry for it under /etc/ld.so.conf.d.

/usr/local/lib/libgretl-1.0.so exists and points to libgretl-1.0.so.16.0.0 in the same
directory.
Ran sudo ldconfig
In /etc/ld.so.conf.d/libc.conf I already see /usr/local/lib.
Very strange, since install seemed to go through fine.

say? You should see something resembling

Possibly also relevant, what about "cc -v" and "ld -V"?

Nor there.
So at this point the failure of your compile is a mystery.
Could you try bypassing "make" by running the following shell
command (in the gretl durectory that contains simple_client.c):
cc -g -O2 -Wall -I/usr/local/include \
-I/usr/include/libxml2 \
-I/usr/include/glib-2.0 \

Thanks.

Terrific! Now it compiles... but here are some details:
Entering the above command in shell gave me a different set of errors unrelated to
libgretl, i.e. undefined reference to daxpy_undefined reference to dtrmm_. etc...
I'm not a fortran expert but it seemed like those errors were related to fortran
routines. I then did sudo apt-get install gfortran. Then went back to the gretl download
folder. Did ./configure, make, make install. Finally, I again entered the above command
you specified in shell, then it worked:

I'm going to fiddle around and see why the makefiles are not working.
Allin, thank you for your time and help. Much appreciated. Gretl seems like an amazing
piece of software and am excited to start using it.
