出现错误：“ar: 创建 ../lib/libmgr.a”

发布于 2024-11-29 02:57:27 字数 727 浏览 2 评论 0原文

我有一个 bash 脚本，它执行 make，然后在 make 写入 stderr 时中止。代码是这样的：

make all 2>${ERROR_FILE}
ERR=$(cat ${ERROR_FILE})
if [ ! -z "${ERR}" ];
then
    abort "Halted because of errors in make $1: ${ERR}"
fi

但是，make 将以下内容写入文件：

ar: creating ../lib/libmgr.a
ar: creating ../lib/libnet.a
ar: creating ../lib/libeoc.a
ar: creating ../lib/libdvr.a
ar: creating ../lib/libmsg.a
ar: creating ../lib/liblgc.a
ar: creating ../lib/libshm.a
ar: creating ../lib/libsys.a
ar: creating ../lib/librsk.a
ar: creating ../lib/librep.a
ar: creating ../lib/libmdl.a
ar: creating ../lib/libmdb.a
ar: creating ../lib/libdat.a
ar: creating ../lib/libchs.a

这是什么意思？这些是错误吗？如果不是，为什么它们会写入 stderr？

I have a bash script that performs makes and then aborts when a make writes to stderr. The code is like this:

make all 2>${ERROR_FILE}
ERR=$(cat ${ERROR_FILE})
if [ ! -z "${ERR}" ];
then
    abort "Halted because of errors in make $1: ${ERR}"
fi

However, make writes the following to the file:

ar: creating ../lib/libmgr.a
ar: creating ../lib/libnet.a
ar: creating ../lib/libeoc.a
ar: creating ../lib/libdvr.a
ar: creating ../lib/libmsg.a
ar: creating ../lib/liblgc.a
ar: creating ../lib/libshm.a
ar: creating ../lib/libsys.a
ar: creating ../lib/librsk.a
ar: creating ../lib/librep.a
ar: creating ../lib/libmdl.a
ar: creating ../lib/libmdb.a
ar: creating ../lib/libdat.a
ar: creating ../lib/libchs.a

What does this mean? Are these errors? If not, why are they written to stderr?

您可以将 -c 标志与 ar 一起使用，以抑制创建存档时默认写入标准错误的诊断消息。例如：

$ ar -cruv libfoo.a foo.o bar.o baz.o

You can use the -c flag with ar to suppress the diagnostic message that is written to standard error by default when an archive is created. For example:

$ ar -cruv libfoo.a foo.o bar.o baz.o

它们看起来不像错误，它们看起来像是来自 ar 的消息。如果 std err 文件非零，为什么要停止？您也想停止警告吗？如果没有，您可能需要根据 make 命令的状态停止（make 命令后的非零 $? 值表示错误）。

我同意@skjaidev。此外，您还可以更具体地说明您在 ERR 变量中查找的内容。一种方法是

编辑：将引用从 ar 更改为 make

 make ....
 make_rc=$?
 case "${ERR}" in
    *[Ee][Rr][Rr][Oo][Rr]* )
        # real error, modify or duplicate as needed
        echo "real error" >&2
        exit ${make_rc}
    ;;
    *[Ww][Aa][Rr][Nn]* )
        # modify or duplicate as needed for various warning msgs
        echo "real warning $(echo "$ERR" | grep -i warn) >&2
        # exit ?
    ;;
    * )
      # other stuff
    ;;
 esac

我希望这会有所帮助。

I agree with @skjaidev. Additionally, you can also be more specific about what you are looking for in your ERR variable. One approach is

Edit : changed references from ar to make

 make ....
 make_rc=$?
 case "${ERR}" in
    *[Ee][Rr][Rr][Oo][Rr]* )
        # real error, modify or duplicate as needed
        echo "real error" >&2
        exit ${make_rc}
    ;;
    *[Ww][Aa][Rr][Nn]* )
        # modify or duplicate as needed for various warning msgs
        echo "real warning $(echo "$ERR" | grep -i warn) >&2
        # exit ?
    ;;
    * )
      # other stuff
    ;;
 esac

I hope this helps.
