At run time get: "Error while loading shared libraries: libgdal.so.1:"
I am trying to implement the GDAL I/O libraries as a LINUX Newbie.
When I run the test executable after my compile and link I get the error: [firani@tautog gdal-1.7.1]$ ./test ./test: error while loading shared libraries: libgdal.so.1: cannot open shared object file: No such file or directory I do not know how to trace this problem further, but I am still digging. I first managed to build gdal and my admin person installed it for me. I am trying to compile and link the code below using the following command as a test case (I am not running as su): g++ -L/home/firani/USGS/gdal/gdal-1.7.1/.libs -lgdal -o./test test.cpp #include "gdal_priv.h" int main() { GDALDataset *poDataset; GDALAllRegister(); poDataset = (GDALDataset *) GDALOpen( "urbgd001.dat", GA_ReadOnly ); if( poDataset == NULL ) { printf("poDataset is null/n."); } } My link libraries exist locally in my own directories as well as in the /usr/local/lib directories: [firani@tautog gdal-1.7.1]$ locate libgdal /usr/local/lib/libgdal.so.1 /usr/local/lib/libgdal.so /usr/local/lib/libgdal.so.1.14.1 /usr/local/lib/libgdal.la /usr/local/lib/libgdal.a /home/firani/USGS/gdal/gdal-1.7.1/wince/libgdal.la /home/firani/USGS/gdal/gdal-1.7.1/.libs/libgdal.lai /home/firani/USGS/gdal/gdal-1.7.1/.libs/libgdal.a /home/firani/USGS/gdal/gdal-1.7.1/.libs/libgdal.so.1 /home/firani/USGS/gdal/gdal-1.7.1/.libs/libgdal.so.1.14.1 /home/firani/USGS/gdal/gdal-1.7.1/.libs/libgdal.la /home/firani/USGS/gdal/gdal-1.7.1/.libs/libgdal.so /home/firani/USGS/gdal/gdal-1.7.1/libgdal.la under /usr/local/lib my libraries look like this: [firani@tautog lib]$ ls -log *gdal* -rw-r--r-- 1 78499986 May 21 11:53 libgdal.a -rwxr-xr-x 1 1134 May 21 11:53 libgdal.la lrwxrwxrwx 1 17 May 21 11:53 libgdal.so -> libgdal.so.1.14.1 lrwxrwxrwx 1 17 May 21 11:53 libgdal.so.1 -> libgdal.so.1.14.1 -rwxr-xr-x 1 34245042 May 21 11:53 libgdal.so.1.14.home under my local directory my .libs libraries look like this: [firani@tautog gdal-1.7.1]$ cd .libs [firani@tautog .libs]$ ls -log *gdal* -rw-r--r-- 1 78499986 May 21 11:49 libgdal.a lrwxrwxrwx 1 13 May 21 11:49 libgdal.la -> ../libgdal.la -rw-r--r-- 1 1134 May 21 11:49 libgdal.lai lrwxrwxrwx 1 17 May 21 11:48 libgdal.so -> libgdal.so.1.14.1 lrwxrwxrwx 1 17 May 21 11:48 libgdal.so.1 -> libgdal.so.1.14.1 -rwxr-xr-x 1 34245042 May 21 11:48 libgdal.so.1.14.1 I have played around tih my $Path and $PATH environmenal values trying to point to these locations but have had no luck running after recompiling with any combination Currently my $PATH looks like: [firani@tautog .libs]$ echo $PATH .:/home/firani/USGS/gdal/gdal-1.7.1/.libs/:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/firani/bin and my my $Path looks like: [firani@tautog .libs]$ echo $Path .:/home/firani/USGS/gdal/gdal-1.7.1/.libs/:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin |
Hi,
You don't need PATH but LD_LIBRARY_PATH. For the bash shell you can run: Code:
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH Regards |
