在bitcask-“errno”中，rebar编译失败。h”:没有这样的文件-rebarcompilefailswithbitcask-“errno.h”:nosuchfile

I am new to Erlang, so i am going through Joe Armstrong's book "Programming Erlang". In chapter 25 there's an example on how to work with rebar. I followed the instructions and created a Makefile

我是Erlang的新手，所以我要通过Joe Armstrong的书“编程Erlang”。在第25章有一个关于如何使用钢筋的例子。我按照说明创建了一个Makefile

all:
    test -d deps || rebar get-deps
    rebar compile -v
    @erl -noshell -pa './deps/bitcask/ebin' -pa './ebin' -s myapp start

and rebar.config

和rebar.config

{deps, [
    {bitcask, ".*", {git, "git://github.com/basho/bitcask.git", "master"}}
]}.

Getting the dependencies works, but compiling fails.

获得依赖项有效，但是编译失败。

The verbose output tells me that this command fails

详细输出告诉我该命令失败

cmd: cc -c $CFLAGS -g -Wall -fPIC  -I"/usr/lib/erlang/lib/erl_interface-3.7.18/include" -I"/usr/lib/erlang/erts-6.2/include"   c_src/bitcask_nifs.c -o c_src/bitcask_nifs.o

with this error

与这个错误

/home/user/folder/deps/bitcask/c_src/bitcask_nifs.c:22:19: fatal error: errno.h: No such file or directory

But

但

find /usr/include -name errno.h

gives me

给我

/usr/include/x86_64-linux-gnu/asm/errno.h
/usr/include/asm/errno.h
/usr/include/linux/errno.h
/usr/include/asm-generic/errno.h

So I was asking myself..

所以我问自己。

• what am I missing?
• 我缺少什么?
• how can I tell rebar about the depencies on the C libraries and where to find them?
• 如何告诉rebar关于C库的依赖关系以及在哪里找到它们?
• why isn't this configured correctly in the Makefile of bitcask?
• 为什么不能在bitcask的Makefile中正确配置它呢?

Maybe I was searching for the wrong terms, but I couldn't find any solution in the internets.
Many thanks in advance

也许我在寻找错误的术语，但是我在互联网上找不到任何解决方案。提前感谢

1 个解决方案

all: ERL_CFLAGS = "$ERL_CFLAGS -I /usr/include/linux/errno.h"
all: 
    test -d deps || rebar get-deps
    rebar compile -v
    @erl -noshell -pa './deps/bitcask/ebin' -pa './ebin' -s myapp start
