Hi Everyone,

I have missed something... I am unable to even get rsyslog to configure before compiling. I am running a fresh install of FreeBSD 6.2 and Mysql 4.1.21.

Rsyslog 1.19.10


When I run ./configure here is what I see:

checking mysql/mysql.h usability... no
checking mysql/mysql.h presence... no
checking for mysql/mysql.h... no
configure: error: MySQL is missing
See `config.log' for more details.


What have I missed?
Thanks in advance everyone.

• Custom written rsyslog.conf?
• Maintenance Contract?
• Installation support?

In a similar thread, I cannot get my mysqlclient libraries recongnized.
their are in ldconfig and LDFLAGS

I'm running Centos 5.

[root@harry rsyslog-2.0.2]# ./configure --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --sbindir=/sbin --disable-static --enable-mysql
.

checking for mysql/mysql.h... yes
checking for mysql_config... yes
checking for mysql_init in -lmysqlclient... no
configure: error: MySQL library is missing
See `config.log' for more details.
[root@harry rsyslog-2.0.2]# rpm -ql mysql-devel-5.0.22-2.2.el5_1.1 | grep mysqlclient
/usr/lib/mysql/libmysqlclient.a

[root@harry rsyslog-2.0.2]# echo $LDFLAGS

[root@harry rsyslog-2.0.2]# ldconfig -v | grep -E "^/|mysql"
/usr/lib/mysql:
libmysqlclient_r.so.15 -> libmysqlclient_r.so.15.0.0
libmysqlclient.so.15 -> libmysqlclient.so.15.0.0
/usr/lib64/mysql:
libmysqlclient_r.so.15 -> libmysqlclient_r.so.15.0.0
libmysqlclient.so.15 -> libmysqlclient.so.15.0.0

That's weird, why are they at /usr/lib/mysql and not /usr/lib/ ?
libmysqlclient.so should really be in /usr/lib.
Anyways, what does mysql_config --libs say?

Also, please check config.log, as ./configure said.

Redhat likes to put stuff in it's own section.
It's a lot easier to have a directory containing config files than 1 large config
file that you have to edit when a package is removed.

I guess they are starting to apply it to the libraries.

What difference does it make, either LDFLAGS is used or not.
Either ld.so is used, or it's not.

What am I looking for in config.log?

I found several lines like:
configure:23458: gcc -o conftest -g -O2 -W -Wall -Wformat-security -Wshadow -Wcast-align -Wpointer-arith -Wmissing-format-attribute -g -L/usr/lib/mysql -L/usr/lib64/mysql conftest.c >&5

Which tells me that my LDFLAGS are being used.
I should try again without the LDFLAGS.

configure: exit 1

And other than configure failed, it doesn't tell me much.

How about this?
This is from config.log where it is looking for mysql_init.
What is -lz? Or what is this z library?

configure:24649: gcc -o conftest -g -O2 -W -Wall -Wformat-security -Wshadow -Wcast-align -Wpointer-arith -Wmissing-format-attribute -g conftest.c -lmysqlclient -L/usr/lib64/mysql -lmysqlclient -lz -lcrypt -lnsl -lm -L/usr/lib64 -lssl -lcrypto
>&5
/usr/bin/ld: skipping incompatible /usr/lib/libz.so when searching for -lz
/usr/bin/ld: skipping incompatible /usr/lib/libz.a when searching for -lz
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status

-lz is from zlib.
Is there a specific version of zlib that is required?

I do not know that we require a specific version, its pretty plain stuff that is used. Any fairly recent version should do.

Rainer

hmmm... I'm already using 1.2.3.

FWIW, I took it to a 32bit machine, and it compiled nicely.

This lets me suspect the original machine has a problem. I am developing under Fedora 8 / 64 bit and everything runs smoothly... Mabye a problem with mysql-dev?

In any case, I am glad it works.

Rainer

It appears that I had 32/64 bit issues.
I replaced my zlib and openssl packages and things started working.
