请原谅我的无知...我仅将Solaris用于测试感兴趣的C / C ++库。我不是Solaris管理员或Solaris用户。
我在Solaris 11.3 x86上安装了GCC-5，因为我需要一个支持的C ++编译器-std=c++11（有关软件包输出，请参见下文）。Sun的本机GCC是4.8，它不能很好地（或根本不）支持C ++ 11。
不幸的是，安装后我找不到它：
$ g++-5 --version
-bash: g++-5: command not found
$ sudo find /usr -name gcc-5
$ sudo find /bin -name gcc-5
$
为了完整性：
$ /bin/gcc --version
gcc (GCC) 4.8.2
...
$ ls -l /usr/bin/gcc
lrwxrwxrwx 1 root root 18 Jun 7 2016 /usr/bin/gcc -> ../gcc/4.8/bin/gcc
$ which gcc-5
no gcc-5 in /usr/local/bin /usr/local/sbin /bin /sbin /usr/bin /usr/sbin /usr/sfw/bin
编译器在哪里？
根据在Stack Overflow 上的Oracle Solaris 11上安装GCC的说法，它应该/usr/bin/gcc作为符号链接进入。但是答案似乎有点偏离：
$ /usr/bin/gcc --version
gcc (GCC) 4.8.2
...
根据Solaris 11中缺少的GCC，并且服务器已在Server Fault上进行了部署：
/usr/sfw/bin是与Solaris 10捆绑在一起的gcc路径。在Solaris 11.1上，安装后，gcc可直接/usr/bin作为指向以下链接的符号链接使用：/usr/gcc/<version>/bin/gcc
答案似乎也有些偏离。
$ sudo pkg install --accept gcc-5

尝试使用：gcc --version而不是gcc-5 --version
