    C-algorithms library from Sourceforge

    Hello Everyone i just downloaded and installed the c-algorithms package from here http://heanet.dl.sourceforge.net/sourceforge/c-algorithms/c-algorithms-1.2.0.tar.gz but i dont rely know how i can use it when compiling with gcc
    because when i use for example the <arraylist.h> header file and i compile with
    gcc -o main `pkg-config --cflags --libs libcalg1.0` main.c
    I get the error message
    Package libcalg1.0 was not found in the pkg-config search path.
    Perhaps you should add the directory containing `libcalg1.0.pc'
    to the PKG_CONFIG_PATH environment variable
    No package 'libcalg1.0' found
    main.c:2:22: fatal error: arraylist.h: No such file or directory
    #include<arraylist.h>
    ^
    compilation terminated.


    Any help on how to compile using this library. Thanks

    How did you install the package?
    C + C++ Compiler: MinGW port of GCC
    Version Control System: Bazaar

    by typing the following commands sequencially

    ./configure
    make
    make install

    I use linux and the gcc compiler to compile

    Well, maybe the package is named differently, e.g., libcalg1.2, but you're following documentation that was not updated to account for that.

    Perhaps you should add the directory containing `libcalg1.0.pc'

    The pkg-config file is called "libcalg
    -1.0.pc" (note the hyphen) in the source archive you've posted.

    Bye, Andreas

    gcc -o c `pkg-config --cflags --libs libcalg-1.0` main.c

    I still get the error message

    to the PKG_CONFIG_PATH environment variable

    What's the output for the following commands:
    Code:
    echo $PKG_CONFIG_PATH
    find / -name "libcalg-1.0.pc" -print 2> /dev/null
    find /usr/local -name "*calg*" -print 2> /dev/null
    (Shouldn't that thread be moved to the Linux/Tech Board?)

    Bye, Andreas

    The problem has been solve by adding the following lines to the file /etc/environment
    Code:
    	PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
    	LD_LIBRARY_PATH=/usr/local/lib
    The code can now be compiled with
    Code:
    gcc -o name_of_executable `pkg-config --cflags --libs libcalg-1.0` main.c
    Thanks
