windows docker环境，centos7.9镜像

$uname -a
Linux 0c15f8482e48 5.10.16.3-microsoft-standard-WSL2 #1 SMP Fri Apr 2 22:23:49 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

acl-3.5.3-22/app/master/tools/master_ctl/Makefile.in

OS_ENV=$(shell uname -a)
ifeq ($(findstring WSL, $(OS_ENV)), WSL)
    SYSLIB += -liconv
endif

虽然内核有WSL字样，但是还是centos的镜像，不应该加上liconv吧。

可以自行在连接时加上。

[qazwsxedckll]

我的意思是，应该不需要这个判断，docker容器和wsl，uname -a出来是一样的，但是不知道docker用的是什么镜像。

就像这里没有加-liconv的理由一样

#Path for Linux
ifeq ($(findstring Linux, $(OSNAME)), Linux)
    ifeq ($(findstring i686, $(OSNAME)), i686)
        RPATH = linux32
    endif
    ifeq ($(findstring x86_64, $(OSNAME)), x86_64)
        RPATH = linux64
    endif
#   CFLAGS += -DLINUX2
    SYSLIB += -rdynamic
endif

[zhengshuxin]

OS_ENV=$(shell uname -a) ifeq ($(findstring WSL, $(OS_ENV)), WSL) SYSLIB += -liconv endif

这个是针对WSL的环境的编译选项。

[qazwsxedckll]

windows的docker desktop，启动任何一个镜像，uname -a出来，也会带有WSL的字样，但是不代表有iconv，会导致编译不过。并不是只有wsl才会uname -a出来WSL。

[zhengshuxin]

有的Linux上的 glibc 包含有 iconv，有的不包含，需要单独引入，目前还没有更好的办法在 Makefile 中探测到底属于哪种情形，所以只能是粗略地通过 uname -a 来加以区分。

可以直接安装个iconv就好了。apt-get install libiconv-dev。
