[debian-mysql] Bug#742172: "mysql_config --libs" doesn't list all required libs

[Kevin Mitchell]

Package: libmariadbclient-dev
Version: 5.5.36-1
Severity: normal

$ cat > mysql_version.c <<EOF
> #include <stdio.h>
> #include <mysql.h>
> int main(int argc, char **argv)
> {
> printf("MySQL client version: %s\n", mysql_get_client_info());
> return 0;
> }
> EOF
$ gcc mysql_version.c $(mysql_config --libs --cflags)
$ gcc mysql_version.c $(mysql_config --libs --cflags)
/usr/lib/x86_64-linux-gnu/libmariadbclient.a(libmysql.c.o): In function `fetch_float_with_conversion':
(.text+0xb0d): undefined reference to `floor'
. . . and many more

On the other hand,
$ gcc mysql_version.c $(mysql_config --libs_r --cflags)
$ ./a.out
MySQL client version: 5.5.36-MariaDB

The difference is
$ mysql_config --libs
-L/usr/lib/x86_64-linux-gnu -lmariadbclient
$ mysql_config --libs_r
-L/usr/lib/x86_64-linux-gnu -lmariadbclient_r -lpthread -lz -lm -lssl -lcrypto -ldl

On Arch Linux, --libs and --libs_r include the same list of libraries except for mysqlclient/mysqlclient_r
