请教交叉编译报错： libgcc_s.so.1: 版本`GCC_4.2.0'未找到(文件 helloworld 必需的) -- /tank/obsnew/lib/libgcc_s.so.1: 错误的 ELF 类型： ELFCLASS32

[jimy1]

从 Linux 64 位（ Redhat 6.5 ）交叉编译生成 Solaris 5.10 目标可执行程序，golang 语言打印一个 hello world，先从 Solaris 拷贝了头文件和库文件到红帽，再编译 binutils，再编译 gcc-5.1.0，生成 sparc-sun-solaris2.10-gccgo

拷贝到 Solaris 后执行报错：

t5240-1:/tank/obsnew/yinq/shandonglt% ./helloworld
ld.so.1: helloworld: 致命的: libgcc_s.so.1: 版本`GCC_4.2.0'未找到(文件 helloworld 必需的)

[changnet]

libgcc_s.so.1 (GCC_4.2.0) => (version not found) 说明了对应版本的 so 库找不到。你的系统存在 libgcc_s.so.1 这个库，但与编译 aiReqResend 这个程序时的版本(4.2.0)不兼容。

你应该在当前系统重新编译一次这个程序，或者把 4.2.0 版本的拷过来共存(即使能用也有可能存在未知的问题)
