configure: error: C compiler cannot create executables

  • I am trying to upgrade apache 2.2.15 to 2.2.27. While running config.nice taken from apache2.2.15/build I am getting following error:

    checking whether the C compiler works... no
    configure: error: in `/home/vkuser/httpd-2.2.27/srclib/apr':
    configure: error: C compiler cannot create executables
    

    I have tried to search online but no luck. I have also tested out c compiler by running a small test.c script and it runs fine. There were few solution given online like installing 'kernel-devel' package but it did not resolve issue. How can I get this to work?

    Following is the config.log generated:

        This file contains any messages produced by compilers while
        running configure, to aid debugging if configure makes a mistake.

    In my case this was fixed by setting CXX=clang++ and CC=clang before running ./configure

    casey Correct answer

    From the output you've given, you are trying to compile a 32-bit build of apache on a 64 bit system. This is from the intput to configure here:

    --host=x86_32-unknown-linux-gnu host_alias=x86_32-unknown-linux-gnu CFLAGS=-m32 LDFLAGS=-m32
    

    Also see the output lines confirming this:

    configure:3629: checking build system type
    configure:3643: result: x86_64-unknown-linux-gnu
    configure:3663: checking host system type
    configure:3676: result: x86_32-unknown-linux-gnu
    configure:3696: checking target system type
    configure:3709: result: x86_32-unknown-linux-gnu
    

    Here it is using a 64 bit build system but a 32 bit host/target. Further down we see:

    ac_cv_env_CFLAGS_set=set
    ac_cv_env_CFLAGS_value=-m32
    

    This flag tells gcc to produce 32 bit objects. Your error that the C compiler cannot produce executable is likely caused by not having a 32 bit toolchain present.

    Testing your ability to compile 32 bit objects

    You can test this by compiling a small C example with the -m32 flag.

    // Minimal C example
    #include <stdio.h>
    int main()
    {
       printf("This works\n");
       return 0;
    }
    

    Compiling:

    gcc -m32 -o m32test m32test.c
    

    If this command fails, then you have a problem with your compiler being able to build 32 bit objects. The error messages emitted from the compiler may be helpful in remedying this.

    Remedies

    1. Build for a 64 bit target (by removing the configure options forcing a 32 bit build), or
    2. Install a 32 bit compiler toolchain

    @Vishal that seems to confirm you don't have a 32 bit build environment setup. Do you need a 32 bit apache?

    Apparantly yes. The existing apache 2.2.15 was compiled with m32 flag. I want to upgrade it to 2.2.27 instead of performing a fresh 2.2.27 installation. Can I do that by building 64bit target? Or should I install 32bit compiler toolchain for getting it work.

    Thanks. Installing glibc-devel.i386 resolved my issue. Cheers!
