#include <julia.h>
JULIA_DEFINE_FAST_TLS() // only define this once, in an executable (not in a shared library) if you want fast code

int main(int argc, char argv[])
{
/ required: setup the Julia context */
jl_init();

/* run Julia commands */
jl_eval_string("print(sqrt(2.0))");

/* strongly recommended: notify Julia that the
     program is about to terminate. this allows
     Julia time to cleanup pending write requests
     and run all finalizers
*/
jl_atexit_hook(0);
return 0;

}

我用如下命令设置好了 JULIA_DIR: julia 的安装目录，$JULIA_DIR/bin/julia 就是 julia 的 repl；
设置了 JULIA_BINDIR=$JULIA_DIR/bin

export JULIA_DIR=~/julia-1.1.0  # Julia's install dir
export JULIA_BINDIR=$JULIA_DIR/bin

echo $JULIA_DIR 
echo $JULIA_BINDIR

用 文档中的例子与编译条件 报同样的错误。

用 julia-config.jl 脚本编译就没有任何问题

编译 test.c (就是 你的/文档中的第一个 例子)

$JULIA_DIR/share/julia/julia-config.jl --cflags --ldflags --ldlibs | xargs gcc -o test test.c

输出

~$ ./test 
1.4142135623730951

确实通过了， 谢谢
