7z.dll missing RRS feed

  • Question

  • Hi All,

    Currently I am working on 7zip compression. When i run 7zip source code on windows platform its running without any issue.

    But if i use same code on WINCE platform its throwing exception that 7z.dll is missing. I loaded same 7z.dll which i used for windows platform but still same issue continues. Is there separate 7z.dll available for WINCE? If so where can i get it? Need Help.

    Thanks in advance.

  • Hi,

    For debugging the issue, provide the error report/log. Wndows7 or any x86 code will not run directly for WEC.

    And if you want 7zip for wince, download from here.It is working and I have used it in WEC7.

  • You can't use the SAME dll.

    Modify the source code of that dll (7z.dll) and build it for WinCE.

    Or else, you can use the project suggested by Shan.

  • Thanks Shan and Keshava,

    The link you provided is for 7zip .exe file. Where I can get the source code?

  • Your requirement is not exactly application but code ? I don't think it will be available openly. You need to build the available source code of x86 to ARM, WEC platform using platform builder.

  • Thanks Shan,

    Currently I am not working on x86 or ARM. I am using virtual machine to run the code. Is there any other compression algorithm source code that is available for WINCE?

  • The emulator/virtual machine BSP should be able to run either ARM or x86 code (you have to build applications for the target for some target processor). Maybe I missed it but don't see which version of WinCE you are using.

  • Hi,

    I am using WINCE 7 version. And i dont have code for either ARM or x86. I have 7zip source code for  windows 7 platform. And i am using it for WINCE platform with some cosmetic changes. But this code has a line of code which loads 7z.dll file. But 7z.dll which I am having is for Windows platform and not for wince. I am not finding WINCE compatible 7z.dll in internet also. 

    Need help.

  • If you have source code (or it's functionality) of 7z.dll, you can try porting it to WinCE. Otherwise it will not be possible to use that app...

  • Yeah correct, But I didn't find source code.

    Is wince providing any built in file compression techniques? I found "FSCTL_SET_COMPRESSION" but its not working. And do you know any compression algorithm which is supported by WINCE?

  • No ZIP compression, no. You might find something on one of the source code sites that could be ported.

    7-Zip has an ARM-targeted install for Windows Mobile/CE. If your target processor is ARM, it's possible (though not certain) this would work.
