compilation tips and tricks
Here are some common problems I encountered when compiling fossg C libraries.
This includes geos and proj.4.
ON centos, when I issued the make command I saw this:
../../../libtool: line 1223: g++: command not found
The googles suggested
yum install gcc-c++
which worked first time.
If the output from "make install" included the following
----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable during linking
- use the `Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
you need to do this:
echo '/usr/local/lib' >> /etc/ld.so.conf.d/local-lib.conf ldconfig
If things get ugly and the simple steps above do not work, you can use a buckshot approach.
Obviously this should be avoided.
> yum install gcc > yum install make > yum groupinstall "Development Libraries" > yum install glibc-headers glibc glibc-commonglibc-devel > yum update glibc glibc-common glibc-headers glibc-devel
Lather, rinse, repeat as needed.
You should eventually see no errors and no dependency check failures.
