configure: error: ERROR: ProtoBuf compiler headers require

[wangchong666]

1. Download protobuf-all-3.15.1.tar.gz and install success.
2. R CMD INSTALL RProtoBuf_0.4.17.tar.gz

   configure: error: ERROR: ProtoBuf compiler headers required; use '-Iincludedir' in CXXFLAGS for unusual locations.
   [czl@tkpcjk01-07 ~/RProtoBuf]$ configure: error: ERROR: ProtoBuf compiler headers requireno

   After read the configure file i found the error log

   /usr/local/include/google/protobuf/stubs/port.h:115:2: error: #error "Protobuf requires at least C++11."
   #error "Protobuf requires at least C++11."

   So we should add -std=c++11 flag R CMD INSTALL --configure-args="CPPFLAGS='-std=c++11'" RProtoBuf_0.4.17.tar.gz

Debug the configure script。。。

After export LD_LIBRARY_PATH=/usr/local/lib finally install success!!

You may have that wrong. What operating system are you on? What compiler do you use, and what version does it have? I.e. please show g++ --version or clang++ --version or whatever corresponding compiler you use.

We have been enforcing use of C++11 for a long time -- at least for four years now per the git blame below. So when a build fails at your end it usually means ... your compiler is too old.

@eddelbuettel thanks for reply

1. g++ (GCC) 5.4.0 clang++: command not found
2. centos 7

[eddelbuettel]

CentOS 7 and g++ 5.4.0 "should be" good enough.

Re-reading, I think I also jumped at the wrong line in your log output (and you may have misread it too). The other problem we have is

checking if ProtoBuf version >= 2.2.0... configure: error: Need ProtoBuf version >= 2.2.0

So configure, when called from R when trying to compile the RProtoBuf package from source, does find an old version of the protocol buffers library on your system. That too is likely on your end. Here (using Ubuntu) I have

edd@rob:~$ dpkg -l | grep libproto | cut -c-70
ii  libprotobuf-c-dev:amd64                    1.3.3-1build2          
ii  libprotobuf-c1:amd64                       1.3.3-1build2          
ii  libprotobuf-dev:amd64                      3.12.3-2ubuntu2

You may have a library either from CentOS or from a local installation that makes the test go off. The test for this is really simple (once you know to read autoconf which is a little like shell):

## also check for minimum version
AC_MSG_CHECKING([if ProtoBuf version >= 2.2.0])
AC_RUN_IFELSE([AC_LANG_SOURCE([[
#include <google/protobuf/stubs/common.h>
int main() {
   if (GOOGLE_PROTOBUF_VERSION >= 2001000) {
        exit (0);
   } else {
        exit(1);
   }
}
]])],
[pb_version_ok=yes],
[pb_version_ok=no],
[pb_version_ok=yes])
if test x"${pb_version_ok}" == x"no"; then
    AC_MSG_ERROR([Need ProtoBuf version >= 2.2.0])
else
    AC_MSG_RESULT([yes])
fi

There is a four-line C program in there that gets built and which reports back if the version is larger that 2001000 (which is actually more lax then the display; I may have a buglet there). In any event most installations will have Protocol Buffers 3.* these days.

I suggest you build the littler four-liner by hand (and maybe add a printf()) and see where you end up with. That too is really old test code which has worked for many users, including invariably some on CentOS.

@eddelbuettel I copy the exe file generated by the test source code to /tmp/conftest ,and then run ldd /tmp/conftest

    linux-vdso.so.1 =>  (0x00007ffddcdf7000)
    libprotobuf.so.26 => not found
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f5d09002000)
    libstdc++.so.6 => /usr/local/lib64/libstdc++.so.6 (0x00007f5d08c87000)
    libm.so.6 => /lib64/libm.so.6 (0x00007f5d08985000)
    libgcc_s.so.1 => /usr/local/lib64/libgcc_s.so.1 (0x00007f5d0876d000)
    libc.so.6 => /lib64/libc.so.6 (0x00007f5d083ab000)
    /lib64/ld-linux-x86-64.so.2 (0x0000557ed5d3b000)

I think the problem is not mutiple version of protobuf but the LD_LIBRARY_PATH,the program seems do not scan the protobuf install path /usr/local/lib After set LD_LIBRARY_PATH=/usr/local/lib I finally install success.
