I am try to install Synergy. but encountered this error:

configure: error: C++ preprocessor "/lib/cpp" fails sanity check

I not familiar with linux and this is what we use.
Linux 2.6.25-rc2 i686

Some suggest to look for the package gcc-c++ but I dont know what package to use.. because I usually see for fedora.. slackware..


this is the error in the config.log:

Post what distro you are using. You probably don't have all the necessary C++ , gcc development packages installed for compiling that application. Without knowing exactly which distro you are using, it's impossible to offer further help.

That is also my problem.. because I don't know what distro this is.. I think this is from scratch.. i am not sure thought.. how can I check?

result form uname -a

You can find out if you have GCC on your system. Someone explained to me how to do this. You use the "gcc --version" command. If you get it to tell you what version of gcc you have then you have gcc installed. If you try "g++ --version" and you get a version, then you have g++ installed.

GCC has a web: http://gnu.gcc.org

You can download GCC if you do not have it, but you need GCC to bulid it unless you can find a package rpm for your distribution. I had GCC 4.2, but I got errors when trying to compile the Linux kernel 2.4.36 and had to get an earlier version of GCC.
