Hi, while porting kde2 the rebase tool solved some problems for me on using libtools libltdl.
In the past I have to use the LTDL_DLOPEN_DEPLIBS in the config.h of libtldl, which enables loading of all dependency dll's of a lib and because of many dll's used for kde this slow down application loading significantly. If I haven't used this flag, cygwin tells about a "... can't remap ..." problem. After rebasing the dll's from the kdelibs, this error does not happens anymore and I can reject this config option. libltdl/config.h ... /* Define if the OS needs help to load dependent libraries for dlopen(). */ //#define LTDL_DLOPEN_DEPLIBS 1 .... On analysing this problem I added an option "-l" to the rebase tool to list dll's imagebase and -size without rebasing. It's very interesting to see how MS chooses there Imagebase. Because I hacked this very quick, I have used simple FILE structure and fopen/fread calls. Perhaps someone like to change this to iostream functionality. $ rebase -h rebase: unknown option -- h usage: rebase -b BaseAddress [-d] -o Offset <file> ... rebase <file> usage: rebase -l <file> ... list Imagebase and -size of <file> Example: $ rebase -l /opt/kde2/bin/*.dll c:\programme\cygwin\opt\kde2\bin\cygDCOP-1.dll - ImageBase: 74fb0000 ImageSize: 00026000 c:\programme\cygwin\opt\kde2\bin\cygartsc-0.dll - ImageBase: 74f80000 ImageSize: 00007000 c:\programme\cygwin\opt\kde2\bin\cygartsflow-0.dll - ImageBase: 74ee0000 ImageSize: 0007a000 c:\programme\cygwin\opt\kde2\bin\cygartsflow_idl-0.dll - ImageBase: 74e50000 ImageSize: 0006f000 c:\programme\cygwin\opt\kde2\bin\cygartskde.dll - ImageBase: 74df0000 ImageSize: 0003f000 c:\programme\cygwin\opt\kde2\bin\cygkICE-0.dll - ImageBase: 74db0000 ImageSize: 00017000 c:\programme\cygwin\opt\kde2\bin\cygkab-3.dll - ImageBase: 74d30000 ImageSize: 0005e000 c:\programme\cygwin\opt\kde2\bin\cygkbuildsycoca.dll - ImageBase: 74cf0000 ImageSize: 0001d000 c:\programme\cygwin\opt\kde2\bin\cygkdecore-3.dll - ImageBase: 74b30000 ImageSize: 00194000 c:\programme\cygwin\opt\kde2\bin\cygkdefakes-3.dll - ImageBase: 74b00000 ImageSize: 00007000 c:\programme\cygwin\opt\kde2\bin\cygkdeprint-0.dll - ImageBase: 74a50000 ImageSize: 00084000 c:\programme\cygwin\opt\kde2\bin\cygkdeprint_management-0.dll - ImageBase: 749b0000 ImageSize: 00075000 c:\programme\cygwin\opt\kde2\bin\cygkdesu-1.dll - ImageBase: 74960000 ImageSize: 0002d000 c:\programme\cygwin\opt\kde2\bin\cygkdeui-3.dll - ImageBase: 74750000 ImageSize: 001ee000 c:\programme\cygwin\opt\kde2\bin\cygkfile-3.dll - ImageBase: 74690000 ImageSize: 0009c000 c:\programme\cygwin\opt\kde2\bin\cygkio-3.dll - ImageBase: 74590000 ImageSize: 000d2000 c:\programme\cygwin\opt\kde2\bin\cygkjava-1.dll - ImageBase: 74540000 ImageSize: 00027000 c:\programme\cygwin\opt\kde2\bin\cygkjs-1.dll - ImageBase: 744d0000 ImageSize: 00044000 c:\programme\cygwin\opt\kde2\bin\cygkmedia2-0.dll - ImageBase: 74480000 ImageSize: 00025000 c:\programme\cygwin\opt\kde2\bin\cygkmedia2_idl-0.dll - ImageBase: 74400000 ImageSize: 00054000 c:\programme\cygwin\opt\kde2\bin\cygkmid-0.dll - ImageBase: 743c0000 ImageSize: 0001b000 c:\programme\cygwin\opt\kde2\bin\cygkonq-3.dll - ImageBase: 74300000 ImageSize: 0009c000 c:\programme\cygwin\opt\kde2\bin\cygkonqsidebartree_bookmarks-0.dll - ImageBase: 742d0000 ImageSize: 0000e000 c:\programme\cygwin\opt\kde2\bin\cygkparts-1.dll - ImageBase: 74270000 ImageSize: 00033000 c:\programme\cygwin\opt\kde2\bin\cygkspell-3.dll - ImageBase: 74220000 ImageSize: 00029000 c:\programme\cygwin\opt\kde2\bin\cygkssl-2.dll - ImageBase: 741d0000 ImageSize: 0002e000 c:\programme\cygwin\opt\kde2\bin\cygksycoca-3.dll - ImageBase: 740f0000 ImageSize: 000b9000 c:\programme\cygwin\opt\kde2\bin\cygktexteditor-0.dll - ImageBase: 740c0000 ImageSize: 0000f000 c:\programme\cygwin\opt\kde2\bin\cygltdl-0.dll - ImageBase: 74090000 ImageSize: 0000a000 c:\programme\cygwin\opt\kde2\bin\cygmcop-0.dll - ImageBase: 73f60000 ImageSize: 00101000 c:\programme\cygwin\opt\kde2\bin\cygmcop_mt-0.dll - ImageBase: 73f30000 ImageSize: 00007000 c:\programme\cygwin\opt\kde2\bin\cygqtmcop-0.dll - ImageBase: 73ef0000 ImageSize: 0001f000 c:\programme\cygwin\opt\kde2\bin\cygsoundserver_idl-0.dll - ImageBase: 73e70000 ImageSize: 0005a000 c:\programme\cygwin\opt\kde2\bin\cygxml2-2.dll - ImageBase: 73dc0000 ImageSize: 00085000 c:\programme\cygwin\opt\kde2\bin\cygxslt-0.dll - ImageBase: 73d70000 ImageSize: 00021000 Regards Ralf
