| 7 | v3.2.2 Alpha 2:
|
|---|
| 8 | ---------------
|
|---|
| 9 |
|
|---|
| 10 | A few bugfixes and a couple of new features.
|
|---|
| 11 |
|
|---|
| 12 | o The TCP/IP headers and libraries scheme have been changed.
|
|---|
| 13 | The default is the current OS/2 tcpip toolkit (BSD 4.4 based).
|
|---|
| 14 | To target the older OS/2 tcpip stack (BSD 4.3 based) you must
|
|---|
| 15 | define TCPV40HDRS before including any TCP/IP headers and make
|
|---|
| 16 | sure usr/lib/tcpipv4 is searched before usr/lib (this is to get
|
|---|
| 17 | the right libsocket). It is recommended to use the -D compiler
|
|---|
| 18 | option for the define and either the LIBRARY_PATH or the -L
|
|---|
| 19 | compiler/linker option for the library.
|
|---|
| 20 |
|
|---|
| 21 | o There are a couple of new and updated based on FreeBSD 5.1.
|
|---|
| 22 | sys\stdint.h and inttypes.h (and a few internal once) are new.
|
|---|
| 23 | sys\types.h and unistd.h are the ones most heavily updated.
|
|---|
| 24 | We're working on getting the headers and libc in a better shape
|
|---|
| 25 | standardwise to easy compatability and portability.
|
|---|
| 26 |
|
|---|
| 27 | o A infinite loop in emxomf has been fixed.
|
|---|
| 28 |
|
|---|
| 29 | o Linker error on sopen() has been corrected.
|
|---|
| 30 |
|
|---|
| 31 | o .... what did we forget...
|

| 32 |
|

|

| 34 | v3.2.2 Alpha 1:
|
|---|
| 35 | ---------------
|
|---|
| 36 |
|
|---|
| 37 | This is the first release from Innotek, and it contains the Innotek LIBC.
|
|---|
| 38 | In addition to the new LIBC there is a number of other major changes:
|
|---|
| 39 |
|
|---|
| 40 | o Name mangling in OMF mode have changed.
|
|---|
| 41 | Until this release emxomf used to pretty much strip one leading '_'
|
|---|
| 42 | from symbols when converting them to omf. This is now longer done
|
|---|
| 43 | chiefly in order to correctly support mangling calling conventions
|
|---|
| 44 | like __stdcall and __cdecl. This change have the following side
|
|---|
| 45 | effects:
|
|---|
| 46 | - _System and __cdecl no longer produces the same names and hence
|
|---|
| 47 | all OS/2 API which are _System must be declared as _System in
|
|---|
| 48 | order to link.
|
|---|
| 49 | - Assembly code might need an extra underscore to work, or
|
|---|
| 50 | perhaps change the prototypes to _System.
|
|---|
| 51 | - Global variables are prepended and underscore, so mixing VAC and
|
|---|
| 52 | GCC, or accessing globals from asm, take care.
|
|---|
| 53 | (MSC v6.0 does this too, so it's not any uncommon practise.)
|
|---|
| 54 |
|
|---|
| 55 | The OS/2 headers which are included are all updated to use _System.
|
|---|
| 56 |
|
|---|
| 57 | o TCPIP headers are updated a quite a bit to match the toolkit ones
|
|---|
| 58 | and to reflect the fact that the new libc does not a having common
|
|---|
| 59 | handle space for files and sockets. These changes aren't 100%
|
|---|
| 60 | completed yet, and usage probably will uncover some issues left in
|
|---|
| 61 | there. Also for the programmer there is the following changes in
|
|---|
| 62 | the apis provided:
|
|---|
| 63 | - TCPV40HDRS are supported and should work like with the toolkit
|
|---|
| 64 | headers. It will alias all functions to tcpip40_ editions
|
|---|
| 65 | (using #defines) so we get the right imports thru -llibsocket.
|
|---|
| 66 | - There is no support for sockets in select(). To do select on
|
|---|
| 67 | sockets you will have to use bsdselect() or os2_select().
|
|---|
| 68 | bsdselect() is only available for TCPV40HDRS. For
|
|---|
| 69 | !defined(TCPV40HDRS) fd_set is in the emx/bsd format and not the
|
|---|
| 70 | OS/2 tcpip v5.0 format.
|
|---|
| 71 | - Socket IOCTLs are not supported by the ioctl() libc function
|
|---|
| 72 | because of the separate handle space for sockets. For sockets
|
|---|
| 73 | so_ioctl() and os2_ioctl() are used. os2_ioctl() is not available
|
|---|
| 74 | when TCPV40HDRS is defined. According to the tcpref in v5.0
|
|---|
| 75 | so_ioctl() only supports BSD ioctls.
|
|---|
| 76 | - writev() and readv() also clashes with libc. For socket handles
|
|---|
| 77 | use so_writev() and so_readv().
|
|---|
| 78 |
|
|---|
| 79 | o The prefered OMF linker is now ilink. link386 will fail with an odd
|
|---|
| 80 | error message if you tell gcc/g++ to make debug info. Set the
|
|---|
| 81 | EMXOMFLD_LINKER environment variable to value ilink in order to use
|
|---|
| 82 | ilink as OMF linker.
|
|---|
| 83 | It likely that we will change the default OMF linker to ilink in an
|
|---|
| 84 | later version of the GCC suite.
|
|---|
| 85 |
|
|---|
| 86 | o .... what did we forget...
