1README_zOS.txt for version 7.3 of Vim: Vi IMproved. 2 3This readme explains how to build Vim on z/OS. Formerly called OS/390. 4See "README.txt" for general information about Vim. 5 6Most likely there are not many users out there using Vim on z/OS. So chances 7are good, that some bugs are still undiscovered. 8 9Getting the source to z/OS: 10========================== 11 12First get the source code in one big tar file and ftp it a binary to z/OS. If 13the tar file is initially compressed with gzip (tar.gz) or bzip2 (tar.bz2) 14uncompress it on your PC, as this tools are (most likely) not available on the 15mainframe. 16 17To reduce the size of the tar file you might compress it into a zip file. On 18z/OS Unix you might have the command "jar" from java to uncompress a zip. Use: 19 jar xvf <zip file name> 20 21Unpack the tar file on z/OS with 22 pax -o from=ISO8859-1,to=IBM-1047 -rf vim.tar 23 24Note: The Vim source contains a few bitmaps etc which will be destroyed by 25this command, but these files are not needed on zOS (at least not for the 26console version). 27 28 29Compiling: 30========== 31 32Vim can be compiled with or without GUI support. For 7.3 only the compilation 33without GUI was tested. Below is a section about compiling with X11 but this 34is from an earlier version of Vim. 35 36Console only: 37------------- 38 39If you build VIM without X11 support, compiling and building is nearly 40straightforward. 41 42Change to the vim directory and do: 43 44 # Don't use c89! 45 # Allow intermixing of compiler options and files. 46 47 $ export CC=cc 48 $ export _CC_CCMODE=1 49 $./configure --with-features=big --without-x --enable-gui=no 50 $ cd src 51 $ make 52 53 There may be warnings: 54 - include files not found (libc, sys/param.h, ...) 55 - Redeclaration of ... differs from ... 56 -- just ignore them. 57 58 $ make test 59 60 This will produce lots of garbage on your screen (including error 61 messages). Don't worry. 62 63 If the test stops at one point in vim (might happen in test 11), just 64 press :q! 65 66 Expected test failures: 67 11: If you don't have gzip installed 68 24: test of backslash sequences in regexp are ASCII dependent 69 42: Multibyte is not supported on z/OS 70 55: ASCII<->EBCDIC sorting 71 57: ASCII<->EBCDIC sorting 72 58: Spell checking is not supported with EBCDIC 73 71: Blowfish encryption doesn't work 74 75 $ make install 76 77 78With X11: 79--------- 80 81WARNING: This instruction was not tested with Vim 7.3. 82 83There are two ways for building VIM with X11 support. The first way is simple 84and results in a big executable (~13 Mb), the second needs a few additional 85steps and results in a much smaller executable (~4.5 Mb). This examples assume 86you want Motif. 87 88 The easy way: 89 $ export CC=cc 90 $ export _CC_CCMODE=1 91 $ ./configure --enable-max-features --enable-gui=motif 92 $ cd src 93 $ make 94 95 With this VIM is linked statically with the X11 libraries. 96 97 The smarter way: 98 Make VIM as described above. Then create a file named 'link.sed' with the 99 following content (see src/link.390): 100 101 s/-lXext *//g 102 s/-lXmu *//g 103 s/-lXm */\/usr\/lib\/Xm.x /g 104 s/-lX11 */\/usr\/lib\/X11.x /g 105 s/-lXt *//g 106 s/-lSM */\/usr\/lib\/SM.x /g 107 s/-lICE */\/usr\/lib\/ICE.x /g 108 109 Then do: 110 $ rm vim 111 $ make 112 113 Now Vim is linked with the X11-DLLs. 114 115 See the Makefile and the file link.sh on how link.sed is used. 116 117 118
