when install the memtier, I got the error

  ./configure: line 5167: syntax error near unexpected token `LIBEVENT_OPENSSL,'
  ./configure: line 5167: `       PKG_CHECK_MODULES(LIBEVENT_OPENSSL,'

OS : Centos libevent-2.0.22-stable has been installed

My install step is:

 1: install libevent, 
         wget https://github.com/libevent/libevent/releases/download/release-2.0.22-stable/libevent-2.0.22-stable.tar.gz
         tar xvzf libevent-2.0.22-stable.tar.gz
         cd libevent-2.0.22-stable
        ./configure
         make && make install

  2: config the libevent
           echo "export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:\${PKG_CONFIG_PATH}" >> /etc/profile
           source /etc/profile
            ldconfig /usr/local/lib

 3: install memtier_benchmark-1.3.0
         autoreconf -ivf
        ./configure --prefix=/usr/local/memtier       
   now , got the error above

@gxkevin Looks like an autoconf issue, make sure you have pkg-config installed before running autoreconf.

yes，I have already install the pkg-config @yossigo

 []# which pkg-config
      /usr/bin/pkg-config
    pkg-config -version
        1.4.2

[yossigo]

@gxkevin But also please confirm that you've executed autoreconf after the package was installed. Otherwise the generated configure script would not work.

I am having same problem. what would be right way to fix if package was installed after executing autoreconf ?

[yossigo]

@tgupta-adc autoreconf -ivf should be able to set up the build tree properly. If that's not working, please provide information about your OS / Linux Distro / Version.

@yossigo Probably I have different issue. I am seeing this error . I am using CentOS Linux release 7.8.2003 shard_connection.cpp:198:79: error: ‘bufferevent_openssl_socket_new’ was not declared in this scope sockfd, ctx, BUFFEREVENT_SSL_CONNECTING, BEV_OPT_CLOSE_ON_FREE); ^ shard_connection.cpp: In member function ‘void shard_connection::handle_event(short int)’: shard_connection.cpp:518:61: error: ‘bufferevent_get_openssl_error’ was not declared in this scope while ((sslerr = bufferevent_get_openssl_error(m_bev))) { ^ make[1]: *** [memtier_benchmark-shard_connection.o] Error 1

@tgupta-adc Did you run ./configure successfully before attempting to build?

I was able to get is working on Ubuntu20.04 VM, Centos is still a problem, but not a blocker for me

[yossigo]

@tgupta-adc Strange, because the configure script should confirm libevent_openssl is available before enabling it. I also don't see this reproducing on a vanilla CentOS environment, so it might be something special in your setup.

@yossigo Hello! I'm totally follow the steps on the README.md, but also meet this problem . ./configure: line 5665: syntax error near unexpected token LIBEVENT_OPENSSL, ./configure: line 5665: PKG_CHECK_MODULES(LIBEVENT_OPENSSL,

My OS information as follows: Operating System: CentOS Linux 7 (Core) Kernel: Linux 3.10.0-1127.el7.x86_64

And my libevent version is libevent-2.0.22-stable.

But I execute ./configure successfully on another machine with Ubuntu 22.04.3 LTS and 5.15.0-88-generic kernel.

[yossigo]

@Jude-Lu Make sure you have pkgconfig installed, and run autoreconf -ivf prior to executing ./configure to refresh the script.

[Jude-Lu]

@yossigo I have fixed the bug using four steps :)

1. upgraded the pkg-config from 0.27 version to 0.29. But it still reports an error: cannot find libssl;
2. located the direction of libssl using 'ldconfig -p | grep libssl';
3. found the libssl.pc using find /lib64/ -name libssl.pc 2>/dev/null. The /lib64 is the output of step 2 on my machine;
4. exportd the output of step 3, /lib64/pkgconfig/, to the enviroment variable PKG_CONFIG_PATH.
