Re: [Lcd4linux-devel] cfg_get() > Segmentation fault

Hi all.

First, I think there is a problem with the Makefile. The configure script detects I have MySQL and pluging_mysql.c is compiled, but when compiling, it shows errors like:
undefined reference to `mysql_init'
undefined reference to `mysql_real_connect'
etc

It's because MySQL libraries are in the mysqlclient library. So while compiling a MySQL program, it is necessary to add the -lmysqlclient compiler option.
I don't know how makefile is generated, but it should include the -lmysqlclient compiler option if MySQL is installed.
I've patched manually the Makefile adding "CC = gcc  -lmysqlclient" but it is not very elegant.

Now I return to my "loved" Segmentation fault ;)

I enclose the code and a sample lcd4linux.conf. In order to test MySQL pluging , just change the display settings to fit your display.
I've also created a MySQL account on my server, so developers can test the pluging (Only select privileges). Server, login, password and db are listed in the sample lcd4linux.conf file.

Here is gdb output:
Program received signal SIGSEGV, Segmentation fault.
0x080642a4 in cfg_get ()
