[Gretl-users] undefined reference when trying to compile

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_new'gretl_test.c:(.text+0x3a): undefined reference to `datainfo_new'gretl_test.c:(.text+0x51): undefined reference to `gretl_read_native_data'gretl_test.c:(.text+0x83): undefined reference to `pprintf'gretl_test.c:(.text+0x94): undefined reference to `errmsg'gretl_test.c:(.text+0xb0): undefined reference to `pprintf'gretl_test.c:(.text+0xc5): undefined reference to `print_smpl'gretl_test.c:(.text+0xd8): undefined reference to `varlist'gretl_test.c:(.text+0xe4): undefined reference to `destroy_dataset'gretl_test.c:(.text+0xf0): 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.
