At first; Different with the desktop window application; There is not the problem of compatible 16 application programs in the WinCE application program, need not to keep minimum DOS space, so the development environment of the application program of WinCE is often very lowly fixed executable application programs reflection loading address; 0x10000 for example, and don't relocation information is provided; And the Wine application program has kept the 0x110000 of user's space address least significant end, and promptly use is not allowed in the space of 17 64KB.Therefore when the application program of WinCE is loaded through Wine, the problem of failure can appear loading.
Secondly, in order to carry out the application program of WinCE, Wine Server can generate wine-pthread, and wine-pthread and WinCE target images belong to same address space, therefore possibly form conflict.
Summary of the invention
In order to solve above-mentioned technical matters, provide a kind of application program has been loaded into the method and system on the peace Zhuo Shouji, its purpose is, has solved the problem of loading failure when on the Android mobile phone, passing through Wine application program operation WinCE binary image.
The invention provides and a kind of application program is loaded into the method for peace on the Zhuo Shouji, comprising:
Step 1 judges whether the loading address of application binaries reflection is in conflict range; If, execution in step 2, otherwise middleware is loaded into the application binaries reflection on the peace Zhuo Shouji;
Step 2, the base address of revising the application binaries reflection is to avoid conflict range, and middleware is loaded into the application binaries reflection on the peace Zhuo Shouji according to the base address of amended application binaries reflection;
Wherein, said application program is not based on the application program of the tall and erect operating system of peace.
In one example, said application program is the application program based on WinCE operating system or WindowsMobile operating system; Said middleware is the Wine application program.
In one example; In the step 1, the base address of application binaries reflection is more than or equal to 0x110000, and the base address does not have when occupied; The loading address of application binaries reflection is not in conflict range, otherwise the loading address of application binaries reflection is in conflict range.
In one example, in the step 3, revise the base address of application binaries reflection through the map_view function in the Wine application program; It is NULL that second of map_view function imported parameter into.
In one example, this method also comprises step 4, and the mapping address of the wine-pthread that Wine Server generates is set to 0x80000000.
The invention provides and a kind of application program is loaded into the system of peace on the Zhuo Shouji, comprising:
The conflict determination module is used to judge whether the loading address of application binaries reflection is in conflict range;
The address modification module, when being used for being in conflict range in the loading address of application binaries reflection, the base address of revising the application binaries reflection is to avoid conflict range;
Middleware when being used for not being in conflict range in the loading address of application binaries reflection, being loaded into the application binaries reflection according to this loadings address of application binaries reflection and pacifying on the Zhuo Shouji; Perhaps the base address according to amended application binaries reflection is loaded into the application binaries reflection on the peace Zhuo Shouji;
Wherein, said application program is not based on the application program of the tall and erect operating system of peace.
In one example, said application program is the application program based on WinCE operating system or WindowsMobile operating system; Said middleware is the Wine application program.
In one example; In the base address of application binaries reflection more than or equal to 0x110000; And the base address does not have when occupied, and the loading address of application binaries reflection is not in conflict range, otherwise the loading address of application binaries reflection is in conflict range.
In one example, the map_view function in the Wine application program is revised the base address of application binaries reflection; It is NULL that second of map_view function imported parameter into.
In one example, the address modification module, the mapping address that also is used for the wine-pthread of Wine Server generation is set to 0x80000000.
The invention solves the problem of loading failure when on the Android mobile phone, passing through Wine application program operation WinCE binary image; Need not the operating system of mobile phone is made amendment; The collision detection of mapping address and the process that remaps are transparent fully to the user.
Description of drawings
Fig. 1 is the memory pattern of WinCE and (SuSE) Linux OS;
Fig. 2 is that WinCE application binaries reflection is redirected the process flow diagram that loads on the Android mobile phone.
Embodiment
The present invention is directed on the Android mobile phone problem of moving the address space conflicts that the WinCE application program produces through Wine; Designed a kind of technical scheme that the WinCE binary image is loaded on the Android mobile phone; Do not provide under the situation of relocation information at WinCE application binaries reflection; Need not carry out the modification of Android cell phone system kernel, solve the WinCE application program smoothly and on the Android mobile phone, load the problem that failure occurs through the Wine application program.
The flow process that application program is loaded on the Android mobile phone provided by the invention is as shown in Figure 2, comprising:
