bidorbuy commented on DAEMON-354:
---------------------------------
I am really surprised that this has not been addressed. We are busy migrating
to Tomcat 8.5.11 with Apache Tomcat Native library 1.2.10 and the warning still
exists (as Tomcat 8.5.x still ships with commons-daemon-1.0.15-native-src)
> DMESG reports: warning: `jsvc' uses 32-bit capabilities (legacy support in
> use)

> Affects Versions: 1.0.15
> Environment: {code}
> Server version: Apache Tomcat/8.0.36
> Server built: Jun 9 2016 13:55:50 UTC
> Server number: 8.0.36.0
> OS Name: Linux
> OS Version: 3.10.0-327.28.3.el7.x86_64

> Dmesg on CentOS7 displays the following warning:
> {code}
> [ 22.742524] warning: `jsvc' uses 32-bit capabilities (legacy support in
> use)
> {code}
> To reproduce we run the following on CentOS 7:
> 1) Install Tomcat 8.0.36
> {code}
> wget -O /tmp/tomcat8.tgz
> http://apache.saix.net/tomcat/tomcat-8/v8.0.36/bin/apache-tomcat-8.0.36.tar.gz
>
> cd /tmp
> tar -zxvf /tmp/tomcat8.tgz
> mkdir /usr/share/tomcat8
> mv /tmp/apache-tomcat-8.0.36/* /usr/share/tomcat8
> {code}
> 2) Compile native library
> {code}
> yum install apr-devel gcc make zlib-devel
>
> tar -xvzf /usr/share/tomcat8/bin/tomcat-native.tar.gz -C /tmp
> cd /tmp/tomcat-native-1.2.7-src/native/
> ./configure --with-apr=/usr/bin/apr-1-config
> --with-java-home=/usr/java/default/ --with-ssl=no --prefix=/usr/share/tomcat8
> make
> make install
> {code}
> 3) Compile jsvc
> {code}
> ## Extract and compile from source:
> tar -xvf /usr/share/tomcat8/bin/commons-daemon-native.tar.gz -C /tmp/
> cd /tmp/commons-daemon-*-native-src/unix
> ./configure --with-java=/usr/java/latest
> make
>
> ## Adjust permissions/ownership and move the executable into place
> chmod a+x jsvc
> mv jsvc /usr/share/tomcat8/bin/
>
>
> ## Test that the compiled version works
> /usr/share/tomcat8/bin/jsvc --help
> {code}
> Tomcat 8.0.36 ships with DAEMON 1.0.15. I am not sure if the above compile
> settings are wrong or we are missing something?
