Formerly called OS/390. +See "README.txt" for general information about Vim. + +Most likely there are not many users out there using Vim on z/OS. So chances +are good, that some bugs are still undiscovered. + +Getting the source to z/OS: +========================== + +First get the source code in one big tar file and ftp it a binary to z/OS. If +the tar file is initially compressed with gzip (tar.gz) or bzip2 (tar.bz2) +uncompress it on your PC, as these tools are (most likely) not available on +the mainframe. + +To reduce the size of the tar file you might compress it into a zip file. On +z/OS Unix you might have the command "jar" from java to uncompress a zip. Use: + jar xvf <zip file name> + +Unpack the tar file on z/OS with + pax -o from=ISO8859-1,to=IBM-1047 -rf vim.tar + +Note: The Vim source contains a few bitmaps etc which will be destroyed by +this command, but these files are not needed on zOS (at least not for the +console version). + + +Compiling: +========== + +Vim can be compiled with or without GUI support. For 7.4 only the compilation +without GUI was tested. Below is a section about compiling with X11 but this +is from an earlier version of Vim. + +Console only: +------------- + +If you build VIM without X11 support, compiling and building is nearly +straightforward. + +Change to the vim directory and do: + + # Don't use c89! + # Allow intermixing of compiler options and files. + + $ export CC=cc + $ export _CC_CCMODE=1 + $./configure --with-features=big --without-x --enable-gui=no + $ cd src + $ make + + There may be warnings: + - include files not found (libc, sys/param.h, ...) + - Redeclaration of ... differs from ... + -- just ignore them. + + $ make test + + This will produce lots of garbage on your screen (including error + messages). Don't worry. + + If the test stops at one point in vim (might happen in test 11), just + press :q! + + Expected test failures: + 11: If you don't have gzip installed + 24: test of backslash sequences in regexp are ASCII dependent + 42: Multibyte is not supported on z/OS + 55: ASCII<->EBCDIC sorting + 57: ASCII<->EBCDIC sorting + 58: Spell checking is not supported with EBCDIC + 71: Blowfish encryption doesn't work + + $ make install + + +With X11: +--------- + +WARNING: This instruction was not tested with Vim 7.4 or later. + +There are two ways for building VIM with X11 support. The first way is simple +and results in a big executable (~13 Mb), the second needs a few additional +steps and results in a much smaller executable (~4.5 Mb). These examples +assume you want Motif. + + The easy way: + $ export CC=cc + $ export _CC_CCMODE=1 + $ ./configure --enable-max-features --enable-gui=motif + $ cd src + $ make + + With this VIM is linked statically with the X11 libraries. + + The smarter way: + Make VIM as described above. Then create a file named 'link.sed' with the + following content (see src/link.390): + + s/-lXext *//g + s/-lXmu *//g + s/-lXm */\/usr\/lib\/Xm.x /g + s/-lX11 */\/usr\/lib\/X11.x /g + s/-lXt *//g + s/-lSM */\/usr\/lib\/SM.x /g + s/-lICE */\/usr\/lib\/ICE.x /g + + Then do: + $ rm vim + $ make + + Now Vim is linked with the X11-DLLs. + + See the Makefile and the file link.sh on how link.sed is used. + + |
