[英]Integrating Crashpad with MacOS Qt application
我們的 Qt 應用程序是使用 qmake 構建的。 我們已經從這個提交構建了 Crashpad,目前是 master 的提示。 我們已將 Qt 應用程序與libclient.a
、 libbase.a
、 libhandler.a
、 libutil.a
、 Security.Framework
和AppKit.Framework
相關聯,並添加了相關的包含目錄。 當我們構建我們的應用程序時,我們從 linker 中收到以下錯誤:

當我們調查child_port_server.o
(使用 nm)時,我們發現符號___MIG_check__Request__child_port_check_in_t
未定義。 這導致我們回到out/Default/gen/util/mach/child_port_server.c
,我們發現以下內容:
#if !defined(__MigTypeCheck) && defined(TypeCheck)
#define __MigTypeCheck TypeCheck /* Legacy setting */
#endif /* !defined(__MigTypeCheck) */
...
#if ( __MigTypeCheck )
#if __MIG_check__Request__child_port_subsystem__
#if !defined(__MIG_check__Request__child_port_check_in_t__defined)
#define __MIG_check__Request__child_port_check_in_t__defined
mig_external kern_return_t __MIG_check__Request__child_port_check_in_t(__attribute__((__unused__)) __Request__child_port_check_in_t *In0P)
{
typedef __Request__child_port_check_in_t __Request;
#if __MigTypeCheck
if (!(In0P->Head.msgh_bits & MACH_MSGH_BITS_COMPLEX) ||
(In0P->msgh_body.msgh_descriptor_count != 1) ||
(In0P->Head.msgh_size != (mach_msg_size_t)sizeof(__Request)))
return MIG_BAD_ARGUMENTS;
#endif /* __MigTypeCheck */
#if __MigTypeCheck
if (In0P->port.type != MACH_MSG_PORT_DESCRIPTOR)
return MIG_TYPE_ERROR;
#endif /* __MigTypeCheck */
return MACH_MSG_SUCCESS;
}
#endif /* !defined(__MIG_check__Request__child_port_check_in_t__defined) */
#endif /* __MIG_check__Request__child_port_subsystem__ */
#endif /* ( __MigTypeCheck ) */
由於對 gen 和 ninja 的了解有限,我們試圖通過修改util.ninja
來傳遞-DTypeCheck
標志,但這破壞了編譯。 我們被困住了,我們將感謝社區願意提供的任何幫助!
我們如何修復 linker 錯誤的其余部分?
由於對我們在 Crashpad-dev 中的帖子的回復,我們能夠解決這個問題
將 libbsm 添加到 your.pro 文件
macx: LIBS += -lbsm
將 out/Default/obj/out/Default/gen/util/mach 中的所有 .o 文件添加到 your.pro 文件中
macx: LIBS += /path/to/crashpad/crashpad/out/Default/obj/out/Default/gen/util/mach/mig_output.child_portServer.o
macx: LIBS += /path/to/crashpad/crashpad/out/Default/obj/out/Default/gen/util/mach/mig_output.child_portUser.o
macx: LIBS += /path/to/crashpad/crashpad/out/Default/obj/out/Default/gen/util/mach/mig_output.excServer.o
