It contains all fixes and new features of emxfix01.zip through emxfix03.zip, and new fixes. If you are a programmer who uses emx for creating applications, install emxfix04.zip. If you just use applications which use emx, install the emxrt.zip corresponding to emxfix04.zip (see the ZIP comment). You don't have to install both.

In consequence, emxfix04.zip can be distributed only if distributed with emxsrcr.zip, gccsrc*.zip, gppsrc2.zip, and gbinusrc.zip. Caveat ------ Do not install this fix package unless you have installed emx 0.9d. It does not work with any other release of emx. Do not install emxfix04.zip if you have already installed a later fix package. Problems solved by this fix package ----------------------------------- [emxfix04.zip] o emxdoc: LaTeX and IPF output fixed o various bugs in DB fixed: put() fixed for keys in overflow pages splitting after new key (which is the first on page) fixed applied patches from http://www.sleepycat.com/update/1.85/patch.185.html o sscanf(): Don't set errno (to EACCES) when reaching EOF (C99) o fscanf(): "%[A-]" does not contain a set o strtol(): *END_PTR now points to 'x' instead of '0' for "0x*" o printf(): printf("%#.4g", 0.0) fixed o <ctype.h>: don't define macros when compiling C++ [emxfix03.zip] o emxfix01.zip and emxfix02.zip don't contain html.c and html.h for emxdoc o fork(): Don't call addsockettolist() twice for the same handle o fork(): support 256 DLLs (was 64) o emx.dll options taking numeric arguments now support hexadecimal numbers (prefixed by "0x") o Attempt to fix a bug related to closing sockets (observed in Apache); try set emxopt=-!0x800 if it still does not work o emx.exe now supports up to 1 GB of memory (was 64 MB) o printf(): incorrect output for "%0f" fixed o printf(): incorrect rounding for "%.0f" fixed o printf(): incorrect number of digits for value 0.0 with "%#g" fixed o export another symbol from emxlibc*.dll to resolve 'exception type_info node' o mktime() and ctime() no longer overwrite the structure used by gmtime() and localtime() o Prototypes added for macro functions in <ctype.h> o For C++, don't define wchar_t in the headers o as: input line length limit increased o exp(): incorrect results for +INF and -INF fixed o log(+INF) and log10(+INF): don't set errno to EDOM o <limits.h>: LONG_LONG_MAX renamed LLONG_MAX (etc.) o <math.h>: cbrt() and cbrtl() are now ISO C functions o <arpa/nameser.h>: nested comment cleaned up [emxfix02.zip] o emxfix01.zip does not contain the new versions of c_import.a o the implementation of strstr() has been simplified a bit o all REXX definitions in os2emx.h are now enclosed in #if ... #endif o emxdoc didn't treat '&' (C++!) the same way as '*' in prototypes [emxfix01.zip] o "%[...]" of scanf() should match a _nonempty_ sequence of characters only o malloc(~(size_t)0) succeeded o fseek() didn't work correctly after an attempt to read more than one buffer worth of data beyond EOF with fread() o read() read "x\r\377y" as "x\ry" in text mode o <sys/un.h> no longer tests the TCPIPV4 macro o Prototypes added for inlined functions in <ctype.h> and <stdio.h> o #pragma interface/implementation should work now o libg++ (gpp.a) has been rebuilt with the above fix Features added by this fix package ---------------------------------- [emxfix04.zip] o New function wm_putsn() [emxfix03.zip] o emxdoc: ref{} now makes a hypertext link [emxfix02.zip] [emxfix01.zip] o emxdoc: LaTeX output improved o emxdoc: HTML output added o emxdoc: options renamed (-i, -k, -l, -m, -t -> upper case) Revision indexes ---------------- emx.dll 61 emx.exe 61 emxio.dll 60 emxlibc.dll 63 emxlibcm.dll 64 emxlibcs.dll 64 emxwrap.dll 60 Installing this fix package --------------------------- 1. Stop all processes which use emxlibcm.dll or emxlibcs.dll. Use emxload -qw to stop preloaded programs under OS/2. 2. Unpack emxfix04.zip or emxrt.zip (see introduction) in the root directory of the drive where you have installed emx: cd \ unzip -o emxfix04 (or `unzip -o emxrt') Do not use the -f and -u options of unzip -- the time stamp of header files has not been updated. If you get an error message such as error: cannot create emx/dll/emx.dll about not being able to create a DLL file, create a temporary directory and run emxuzdll.cmd in that directory, giving the path name of emxfix04.zip or emxrt.zip and the path name of the emx DLL directory on the command line: mkdir \emxtmp chdir \emxtmp emxuzdll a:\emxfix04.zip c:\emx\dll chdir .. rmdir emxtmp This will replace the DLLs in c:\emx\dll with the DLLs in emxfix04.zip even if the DLLs are in use. The new versions of the DLLs become active as soon as the last process referencing them is terminated, or on the next reboot. Therefore, you should reboot after running emxuzdll, otherwise you won't know if and when the new versions become active. (Actually, you don't need a temporary directory, any directory not containing any DLL files will do.) 3. Type the following command to rebuild the OMF-style libraries (you don't need this step under DOS): cd \emx\lib emxomf -s -l -q gpp.a mt/c.a st/c.a st/c_p.a emxomf -s -l -q mt/c_import.a st/c_import.a To take advantage of the library fixes, relink your programs. You should keep the file \emx\doc\emxfix04.doc as it shows what fixes you have installed. --------------------------- END OF EMXFIX04.DOC ------------------------------
