[gdal-dev] gdal on fedora 13

[Nahum Castro]

I can not compile gdal 1.72 on fedora 13 beacuse of this.

6.3.1. GCC now uses Implicit DSO linking
Key points:

   1. ld will no longer automatically search in the dependencies of linked
   objects.
   2. If your project used both libraries *A* and *B*, it will not compile
   unless *A* and *B* are both explicitly linked.
   3. There are more explanations on the GCC features page on the Fedora
   wiki:
   http://fedoraproject.org/w/index.php?title=UnderstandingDSOLinkChange.

 Under the new changes, if your package fails its build with a message like:


/usr/bin/ld: gpx-parser.o: undefined reference to symbol 'acos@@GLIBC_2.0'
/usr/bin/ld: note: 'acos@@GLIBC_2.0' is defined in DSO /lib/libm.so.6
so try adding it to the linker command line

Then the line that builds the specified .o needs to explicitly link *libm*.

What i have to modify to implicit DSO linking all libraries.

/bin/sh /home/nahum/Descargas/gdal-1.7.2/libtool --mode=link    g++
gdalmanage.lo  /home/nahum/Descargas/gdal-1.7.2/libgdal.la -o gdalmanage
libtool: link: g++ .libs/gdalmanage.o -o .libs/gdalmanage
/home/nahum/Descargas/gdal-1.7.2/.libs/libgdal.so
/usr/bin/ld: /usr/local/lib/libNCSUtil.so.0: undefined reference to symbol
'pthread_cancel@@GLIBC_2.2.5'
/usr/bin/ld: note: 'pthread_cancel@@GLIBC_2.2.5' is defined in DSO
/lib64/libpthread.so.0 so try adding it to the linker command line
/lib64/libpthread.so.0: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[1]: *** [gdalmanage] Error 1
make[1]: se sale del directorio `/home/nahum/Descargas/gdal-1.7.2/apps'
make: *** [apps-target] Error 2


Thanks in advance
