-lgcc_s 和 gcc 之间的区别
通过 LDFLAGS 链接到 gcc_s 和 gcc 之间有什么区别？
gcc_s 是静态库和gcc 共享库吗？
因为我正在寻找一个解决方案，其中提到链接到 gcc 而只有 gcc_s 在我的情况下有效。我想知道真正的区别。
<<hidden symbol `__name_here' in /some/library/path.a(_filename.o) is referenced by DSO
在这种情况下，通常通过将“-l gcc”或“gcc -print-libgcc-file-name”添加到链接标志 (LDFLAGS) 来解决问题。然而，与我的其他常规平台（i386、amd64、sparc64）不同，这还不够。经过大量的头脑风暴（公平地说，它也来自音乐），我意识到这个标志在链接 libc 和最终可执行文件时都是必要的。 链接：http://people.defora.org/~khorben/200903.html
what is the difference between linking against gcc_s and gcc by means of LDFLAGS?
Is gcc_s a static library and gcc shared library?
Because I was looking for a solution where it is mentioned to link against gcc whereas only gcc_s works in my case. I wish to know the real difference.
<<hidden symbol `__name_here' in /some/library/path.a(_filename.o) is referenced by DSO
In this case, the problem is usually solved by adding either "-l gcc" or "gcc -print-libgcc-file-name" to the linking flags (LDFLAGS). However, unlike my other regular platforms (i386, amd64, sparc64) here it wasn't enough. After a lot of head-banging (to be fair, it also comes from the music) I realized that this flag is necessary both when linking the libc and the final executable file.

libgcc_s.so是共享库，libgcc.a是静态库。它们并不等同；可能有必要将两者联系起来。 libgcc_s 包含全局变量，在一个进程中不得有多个副本； libgcc 中的代码可以安全地链接多次。libgcc_s.sois a shared library,libgcc.ais a static library. They are not equivalent; it may be necessary to link both. libgcc_s contains global variables which must not have multiple copies in a process; the code in libgcc is safe to link multiple times.
