Hi, i'm having some problems to include mysql.h when i compile C source code.
Hello Damian,
I'm using this macro http://autoconf-archive.cryp.to/ax_lib_mysql.html to find the path to mysql.h in a Debian Linux and work fine. $ ./configure ... checking for mysql_config... /usr/bin/mysql_config checking for MySQL libraries... yes ... When i run configure it generates this line in the Makefile file: MYSQL_CFLAGS = -I/usr/include/mysql -DBIG_JOINS=1 MYSQL_CONFIG = /usr/bin/mysql_config MYSQL_LDFLAGS = -L/usr/lib/mysql -lmysqlclient MYSQL_VERSION = 5.0.32 [...] But when i run make it doesn't include the MYSQL_CFLAGS so it's imposible to resolve this #include <mysql.h>
This macro provides you with the flags required to use MySQL in your builds but it does not actually enforce them. And this is a sane behavior. So now, you simply need to use these flags whenever you need them, eg:
bin_PROGRAMS = mysqlcli mysqlcli_SOURCES = ... mysqlcli_CFLAGS = $(MYSQL_CFLAGS) $(AM_CFLAGS) (don't forget to add the AM_*flags in the target-specific_*FLAGS) Or simply... bin_PROGRAMS = mysqlcli mysqlcli_SOURCES = ... AM_CFLAGS = $(MYSQL_CFLAGS)... if you don't already use AM_CFLAGS and all the targets of this Makefile.am must use $(MYSQL_CFLAGS). If you already use AM_CFLAGS, then simply use `+=' instead of `='.
