要成功編譯GnuTLS必須先安裝Libgcrypt，而要成功編譯Libgcrypt又必須依賴Libgpg-error。所以必須按照Libgpg-error->Libgcrypt->GnuTLS的順序進行安裝。具體安裝方法見各程序的INSTALL文檔，以下是在安裝過程中出現的問題以及解決方法。
mpih-add1-asm.S:47:suffix or operands invalid for `push'
mpih-add1-asm.S:48:suffix or operands invalid for `push'
mpih-add1-asm.S:78:suffix or operands invalid for `jmp'
mpih-add1-asm.S:113:suffix or operands invalid for `pop'
mpih-add1-asm.S:114:suffix or operands invalid for `pop'這個錯誤可通過在configure時增加可選項disable-asm來避免。

serv.c:627: warning: passing argument 3 of '__builtin___snprintf_chk' makes integer from pointer without a cast這個錯誤是由於宏snprintf在Mac OS X 10.6下的不兼容造成的。解決方法是修改serv.c中的代碼，將宏tmp2拆成兩個宏。具體修改如下:
-#define tmp2 &http_buffer[strlen(http_buffer)], len-strlen(http_buffer)
+#define tmp2b &http_buffer[strlen(http_buffer)]
+#define tmp2l len-strlen(http_buffer)參考文章：GnuTLS does not build on OS X 10.6 due to incompatibility with snprintf macro
以下是原文中關於錯誤及解決方法的描述:
Code built with gcc on Mac OS X 10.6 uses the object size checking feature of gcc by default. This involves redefining
several functions as macros; one of these functions is snprintf:
#define snprintf(str, len, ...) \
__builtin___snprintf_chk (str, len, 0, __darwin_obsz(str), __VA_ARGS__)
The usage of snprintf in src/serv.c in gnutls-2.10.4 is not compatible with that macro. serv.c attempts to
use a macro (tmp2) that expands into two different arguments:
#define tmp2 &http_buffer[strlen(http_buffer)], len-strlen(http_buffer)
snprintf (tmp2, "%.2X", sesid[i]);
Due to how nested macro evaluation works, the snprintf macro sees tmp2 as a single argument, and copies it
into __darwin_obsz(); then, when tmp2 is expanded, __darwin_obsz has two arguments, but it is only
defined for one, and the result is a compilation error.
One way to work around this issue might be to define _FORTIFY_SOURCE=0 so that the snprintf macro is not
defined, or simply doing an #undef snprintf for that file, but it seems safer and more portable to split
tmp2 into two macros. I append a patch that does so.GnuTLS 的詳細介紹：請點這裡
