Thread: 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

by typing the following commands sequencially

./configure
make
make install

I use linux and the gcc compiler to compile

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

When i compile using

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

I still get the error message

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

Ive tried that but still no help....

I dont rely know how to do that can you help me?

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?)

Thanks i have done that and the code compiles correctly to the executable but i get the error message

Code:

 error while loading shared libraries: libcalg.so.0: cannot open shared object file: No such file or directory

Any help on this?

Did you run make install as root ?

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
