Re: [csmith-dev] Generated code does not compile: undefined reference to `safe_rshift_func_uint16_t_u_s'

[Shafiul Azam <ishafiul@gmail.com>]

Thanks again John. I build it again, now it works. :)

First time when ran "./configure" I indeed did not have m4. Then I installed m4 and built it, but NOT running "./configure" before issuing the "make" command. Do you think that's why it got built wrong?

I think you will find, if you look in your safe_math.h, that it contains nothing.  It is supposed to contain all those functions that your linker is complaining about.  Perhaps you do not have m4 installed on your system, or it didn't work for whatever reason.  Our configure script checks for it, I'll note.

Anyway your build of Csmith is all wrong.

    Hi Shafiul,

    Something basic is going wrong.  We cannot track it down using what
    you have told us so far.  One thing you could do is provide us with
    a preprocessed version of your file.  You can get that for example
    like this:

       gcc -I${CSMITH_PATH}/runtime test.c -E > preprocessed.txt

        Hi Yang,

        Thanks. I did indeed include the runtime. I used this command to
        compile: gcc -I${CSMITH_PATH}/runtime test.c -o test;

        Any idea why this still fails?

             Hi Shafiul,

             You may need to include Csmith's runtime path, e.g.,

             $ pwd
             /home/yangchen/Programs/csmith/src
             $ ./csmith > foo.c
             $ gcc -I ../runtime foo.c > /dev/null 2>&1
             $ ./a.out
             checksum = DAB3BE95

                 Hi,

                 I'm new to csmith (2.2.0) and tried generating code and
                 compiling, but
                 I'm getting lots of these errors:

                 test.c:(.text+0x221): undefined reference to
                 `safe_rshift_func_uint16_t_u_s'
                 test.c:(.text+0x22d): undefined reference to

                 test.c:(.text+0x2ee): undefined reference to
                 `safe_rshift_func_uint16_t_u_u'
                 /tmp/ccksSLp6.o: In function `func_9':

                 test.c:(.text+0x4b8): undefined reference to
                 `safe_rshift_func_uint16_t_u_u'

                 These definitions were indeed missing in the generated
        code. I'm
                 guessing that I'm missing some library. I'm using
        Ubuntu 14.04
                 and gcc
                 4.8.4.

                 Command I used: csmith --no-arrays --no-bitfields
        --no-checksum
                 --no-consts --no-longlong --no-int8 --no-uint8
        --max-block-depth 2
                 --no-structs --no-unions --no-volatiles
        --no-const-pointers > test.c

                 (I tried without passing any options to csmith but the
        result is
                 similar.)

                 I might be doing something stupid and I'm sorry for
        this post,
                 but any
                 help will be highly appreciated.
