I want to use hash tables in my c program.
I code:
...
#include <glib.h>
void main(int argc, char **argv)
{
GHashTable *g_hash_table;
...
g_hash_table = g_hash_table_new(g_int_hash, g_int_equal);
...
}
Then I compile:
$ gcc -I/usr/include/glib-2.0
-I/usr/lib/i386-linux-gnu/glib-2.0/include
-lglib-2.0 -o test test.c
or the same command:
$ gcc `pkg-config --cflags --libs glib-2.0` -o test test.c
but anyway the result is:
test.c: underfined reference to `g_int_equal`
test.c: underfined reference to `g_int_hash`
test.c: underfined reference to `g_hash_table_new`
collect2: ld returned 1 exit status
Why I cant compile my program? I do wrong include of glib library?
您需要在使用它们的源文件和目标文件之后在命令行中指定库:
gcc test.c `pkg-config --cflags --libs glib-2.0` -o test
From this pdf at IBM developper works, it's better to use the pkg-config if you have a standard install of glib
with this command :
$ gcc `pkg-config --cflags --libs glib-2.0` -o ex-compile ex-compile.c
Your include look right and the way you are using it to. Not sure the '
will change anything but you might want to check the PDF, it contains a lot of examples and explainations.
