README_os_390.txt for version 7.0d of Vim: Vi IMproved. Welcome to the OS/390 Unix port of VIM. ATTENTION: THIS IS AN _ALPHA_ VERSION!!! I expect you to know how to handle alpha software! This port was done by Ralf Schandl . This port is not maintained or supported by IBM!! For the list of changes see runtime/doc/os_390.txt. Compiling: ---------- Note: After the file configure was created via autoconf, it had been handedited, to make the test for ICEConnectionNumber work. DO NOT run autoconf again! Without X11: If you build VIM without X11 support, compiling and building is nearly straightforward. The only restriction is, that you can't call make from the VIM toplevel directory. Change to the src directory first and call make from there. Here is a what to do: # Don't use c89! # Make additional symbols visible. # Allow intermixing of compiler options and files. $ export CC=cc $ export CFLAGS=-D_ALL_SOURCE $ export _CC_CCMODE=1 $./configure --enable-max-features --without-x --enable-gui=no $ cd src $ make $ make test Note: Test 28 will be reported as failed. This is because diff can't compare files containing '\0' characters. Test 11 will fail if you don't have gzip. $ make install With X11: 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). This examples assume you want Motif. The easy way: $ export CC=cc $ export CFLAGS="-D_ALL_SOURCE -W c,dll" $ export LDFLAGS="-W l,dll" $ 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 contense: 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. Hint: ----- Use the online help! (See weaknesses below.) Example: Enter ':help syntax' and then press several times, you will switch through all help items containing 'syntax'. Press on the one you are interested at. Or press and you will get a list of all items printed that contain 'syntax'. The helpfiles contains cross-references. Links are between '|'. Position the cursor on them and press to follow this link. Use to jump back. Known weaknesses: ----------------- - You can't call make from the toplevel directory, you have to do a 'cd src' first. If you do it, make will call configure again. I don't know why and didn't investigate it, there were more important things to do. If you can make it work drop me a note. - The documentation was not updated for this alpha release. It contains lot of ASCII dependencies, especially in examples. - Digraphs are dependent on code page 1047. Digraphs are used to enter characters that normally cannot be entered by an ordinary keyboard. See ":help digraphs". - Using 'ga' to show the code of the character under the cursor shows the correct dec/hex/oct values, but the other informations might be missing or wrong. - The sed syntax file doesn't work, it is ASCII dependent. Bugs: ----- If you find a bug please inform me (schandl@de.ibm.com), don't disturb Bram Moolenaar. It's most likely a bug I introduced during porting or some ASCII dependency I didn't notice. Feedback: --------- Feedback welcome! Just drop me a note.
